"Understanding the intricate interplay between cannabinoids,
terpenes, and flavonoids is paramount for realizing the full
therapeutic benefits of cannabis," say Al-Khazaleh et al
(2024)
"Cannabinoids, pivotal in cannabis's bioactivity, exhibit
well-documented analgesic, anti-inflammatory, and neuroprotective
effects. Terpenes, aromatic compounds imbuing distinct flavours, not
only contribute to cannabiss sensory profile but also modulate
cannabinoid effects through diverse molecular mechanisms. Flavonoids,
another cannabis component, demonstrate anti-inflammatory,
antioxidant, and neuroprotective properties, particularly relevant to
neuroinflammation. The entourage hypothesis posits that combined
cannabinoid, terpene, and flavonoid action yields synergistic or
additive effects, surpassing individual compound efficacy. Recognizing
the nuanced interactions is crucial for unravelling cannabiss complete
therapeutic potential. Tailoring treatments based on the holistic
composition of cannabis strains allows optimization of therapeutic
outcomes while minimizing potential side effects."

To this end, Namdar et al of the Institute of Plant Sciences and the
Israeli Gene Bank
"...found that in 'high THC' or 'high CBD' strains, phytocannabinoids
are produced alongside certain sets of terpenoids. Only co-related
terpenoids enhanced the cytotoxic activity of phytocannabinoids on
MDA-MB-231 and HCT-116 cell lines. This was found to be most effective
in natural ratios found in extracts of cannabis inflorescence. The
correlation in a particular strain between THCA or CBDA and a certain
set of terpenoids, and the partial specificity in interaction may have
influenced the cultivation of cannabis and may have implications for
therapeutic treatments."
The scientists discovered that for cytotoxicity in MDA-MB-231 and
HCT-116 cell lines, ingredients that went together went
together.
"In this paper we present a clear example of the inter-entourage
effect on cytotoxic activity. We showed: (1) A significant correlation
between certain terpenoids and the main phytocannabinoids in various
C. sativa strains. (2) Terpenoids, present in relatively minute
amounts in cannabis extracts and possessing no therapeutic effect by
themselves at these concentrations, add to the cytotoxicity of the
dominant phytocannabinoid. This demonstrates the inter-entourage
effect in cannabis treatments. (3) The inter-entourage interaction is
specific, in part, since THC activity was enhanced only by its
co-related terpenoids, at terpenoid to phytocannabinoid ratios found
naturally in the plant, while CBD was more tolerant. (4) The relative
ratio of phytocannabinoid to terpenoids, demonstrating the enhanced
biological activity, entitled entourage effect, showed nonlinear dose
dependency, rather a dose-specificity mode of action."

In 2006 Varvel et al
"investigated whether CBD may modulate the pharmacological effects of
intravenously administered THC or inhaled marijuana smoke on
hypoactivity, antinociception, catalepsy, and hypothermia, the well
characterized models of cannabinoid activity."
They found
"Intravenously administered CBD possessed very little activity on its
own and, at a dose equal to a maximally effective dose of THC (3
mg/kg), failed to alter THC's effects on any measure. However, higher
doses of CBD (ED(50)=7.4 mg/kg) dose-dependently potentiated the
antinociceptive effects of a low dose of THC (0.3 mg/kg). Pretreatment
with 30 mg/kg CBD, but not 3 mg/kg, significantly elevated THC blood
and brain levels."

A UK study by Imperial College looked at childhood epilepsy, again
making the astonishing discovery that THC and CBD work better
together.
"Twenty-three (65.7%) patients achieved a 50% reduction in seizure
frequency. 94.1% (n = 16) of patients treated with CBD and 9 -THC
observed a 50% reduction in seizure frequency compared to 31.6% (n 6)
and 17.6% (n = 3) of patients treated with CBD isolates and
broad-spectrum CBD products, respectively (p< 0.001)."

It's almost as if it's part of some divine plan! In 2017 King et al,
at something called the "Center for Substance Abuse Research" in
Philadelphia discovered that THC and CBD go together! They work better
together at treating the symptoms of anti-cancer drugs with lots of
side effects.
"Both CBD and THC alone attenuated mechanical allodynia
[touch-sensitive pain] in mice treated with paclitaxel. Very low
ineffective doses of CBD and THC were synergistic when given in
combination. CBD also attenuated oxaliplatin- but not
vincristine-induced mechanical sensitivity, while THC significantly
attenuated vincristine- but not oxaliplatin-induced mechanical
sensitivity. The low dose combination significantly attenuated
oxaliplatin- but not vincristine-induced mechanical
sensitivity."

[1325]
Ozmen et al (2024) found CBD reduced the harm caused by another
cancer drug.
"Methotrexate (MTX) is a widely used medication for various cancers,
yet its use is associated with adverse effects on organs, notably the
lungs. Cannabidiol (CBD), known for its antioxidant and
anti-inflammatory properties, was investigated for its potential
protective effects against MTX-induced lung injury. Thirty-two female
Wistar Albino rats were divided into four groups: control, MTX (single
20 mg/kg intraperitoneal dose), MTX + CBD (single
20 mg/kg MTX with 0.1 ml of 5 mg/kg CBD for 7 days
intraperitoneally) and CBD only (for 7 days). Lung tissues were
analysed using histopathological, immunohistochemical and PCR methods
after the study. Histopathological assessment of the MTX group
revealed lung lesions like hyperemia, edema, inflammatory cell
infiltration and epithelial cell loss. Immunohistochemical examination
showed significant increases in Cas-3, tumour necrosis factor-alpha
(TNF-α) and nuclear factor-kappa B (NF-κB) expressions.
PCR analysis indicated elevated expressions of apoptotic peptidase
activating factor 1 (Apaf 1), glucose-regulated protein 78 (GRP 78),
CCAAT-enhancer-binding protein homologous protein (CHOP) and
cytochrome C (Cyt C), along with reduced B-cell lymphoma-2 (BCL 2)
expressions in the MTX group, though not statistically significant.
Remarkably, CBD treatment reversed these findings."

In "Cannabidiol Increases Psychotropic Effects and Plasma
Concentrations of Δ9-Tetrahydrocannabinol Without Improving Its
Analgesic Properties" Gorbenko et al (2024) found the influence of CBD
on THC to be rather different to what most would expect:
"Cannabidiol (CBD), the main non-intoxicating compound in cannabis,
has been hypothesized to reduce the adverse effects of
Δ9-tetrahydrocannabinol (THC), the main psychoactive and
analgesic component of cannabis. This clinical trial investigated the
hypothesis that CBD counteracts the adverse effects of THC and thereby
potentially improves the tolerability of cannabis as an analgesic. A
randomized, double-blind, placebo-controlled, five-way cross-over
trial was performed in 37 healthy volunteers. On each visit, a
double-placebo, THC 9 mg with placebo CBD, or THC 9 mg
with 10, 30, or 450 mg CBD was administered orally.
Psychoactive and analgesic effects were quantified using standardized
test batteries. Pharmacokinetic sampling was performed. Data were
analyzed using mixed-effects model. Co-administration of 450 mg
CBD did not reduce, but instead significantly increased subjective,
psychomotor, cognitive, and autonomous effects of THC (e.g., VAS
'Feeling High' by 60.5% (95% CI: 12.7%, 128.5%,
P < 0.01)), whereas THC effects with 10 and
30 mg CBD were not significantly different from THC alone. CBD
did not significantly enhance THC analgesia at any dose level.
Administration of 450 mg CBD significantly increased AUClast of
THC (AUClast ratio: 2.18, 95% CI: 1.54, 3.08,
P < 0.0001) and 11-OH-THC (AUClast ratio: 6.24, 95%
CI: 4.27, 9.12, P < 0.0001) compared with THC alone,
and 30 mg CBD significantly increased AUClast of 11-OH-THC
(AUClast ratio: 1.89, 95% CI: 1.30, 2.77, P = 0.0013),
and of THC (AUClast ratio: 1.44, 95% CI: 1.01, 2.04,
P = 0.0446). Present findings do not support the use of
CBD to reduce adverse effects of oral THC or enhance THC
analgesia."

Summarising the benefits of cannabis in "Cannabis and cancer:
unveiling the potential of a green ally in breast, colorectal, and
prostate cancer" AlSalamat et al (2024) add to data on the synergy of
cannabinoids and oxaliplatin:
"Oxaliplatin is a chemotherapeutic medication that is used to treat
cancer. It is a platinum medication with alkylating properties (O'Dowd
et al. 2023). Oxaliplatin, like other alkylating drugs, operates by
interfering with the development of DNA in a cell. It kills cells by
preventing them from growing and replicating (O'Dowd et al. 2023).
This aids in the treatment of cancer, which is characterized by
uncontrollable cell growth and division (O'Dowd et al. 2023).
Exploring novel techniques to improve the efficacy of CRC treatment by
identifying molecules and mechanisms linked with oxaliplatin
resistance is necessary (Jeong et al. 2019). CBD has the potential to
assist human CRC cells overcome Oxaliplatin resistance. Jeong et al.
conducted a study to demonstrate the effect of CBD on inducing
autophagy in Oxaliplatin resistance colorectal cancer cell (CRC), they
generated oxaliplatin-resistant cell lines, which didnt respond to
oxaliplatin treatment (Jeong et al. 2019). When the cell lines were
treated with a combination of CBD and oxaliplatin, the death of
oxaliplatin-resistant CRC was considerably raised (Jeong et al. 2019).
The authors also performed an in-vivo study on mice. They injected a
group of mice with oxaliplatin-resistant cell lines subcutaneously,
then they measured the tumor size and weight every 2 days. They found
that both size and weight of tumor were lower in mice that were
treated with both oxaliplatin and CBD than in the non-treated control
group and mice that were treated with either drug. The mechanism
behind this is that CBD decreases NOS3 phosphorylation-which is
essential for Oxaliplatin resistance development- and superoxide
dismutase-2 (which is an intracellular antioxidant) increasing
Reactive Oxygen Species (ROS) through mitochondrial dysfunction
leading to induce autophagy (Jeong et al. 2019)."

[4655]
Summarising the anti-cancer activities of cannabis, Nigro et al (2021)
say:
"Both THC and non-psychoactive cannabinoids have been reported to
possess peripheral anti-inflammatory properties in a plethora of in
vitro and in vivo models. In human peripheral blood cells, CB1 is
expressed by B cells, NK cells, neutrophils, CD8+ T cells, monocytes,
and CD4+ T cells, whereas CB2 mRNA is expressed by human B cells, NK
cells, monocytes, neutrophils, and T cells. Typically, CB2 inhibits
the production of proinflammatory cytokines, such as tumor necrosis
factor alpha (TNF-𝛼), interleukin (IL)-2, IL-6, IL-8, and IFN-𝛾 by
immune cells. CBD decreases peripheral inflammation through reduction
of prostaglandin E2 (PGE2), nitric oxide (NO), and malondialdehyde
production. In addition, CBD, in combination with minor
phytocannabinoids of Cannabis sativa L. extracts, can induce a greater
pharmacological anti-inflammatory activity. Indeed, a standardized
cannabis extract enriched with CBD exerts a more powerful
anti-inflammatory activity than CBD alone. Besides CBD, THC also
possesses potent anti-inflammatory properties both in vivo and in
vitro. Recently, in a mouse model of acute respiratory distress
syndrome, THC leads to the suppression of the cytokine storm. The
molecular mechanisms at the basis of THC down-regulation of the
inflammatory processes are various and tissue-dependent. Indeed,
regarding gastrointestinal and systemic inflammatory reactions, THC
suppresses both lymphocytes and neutrophils activity; in epithelial
and skin cells, THC inhibits the release of inflammatory mediators
through impairment of the nuclear factor kappa-light-chain-enhancer of
activated B cells (NF-kB) pathway. It is of note that there is clear
evidence of the synergistic action of THC and CBD in terms of
down-regulation of the inflammatory processes.
"Regarding other combination extracts, Shebabya et al. demonstrated
that Cannabis sativa L. oil extract markedly suppresses the release of
TNF-α in LPS-stimulated rat monocytes with inhibition of
LPS-induced COX-2 and i-NOS protein expression and blockage of MAPKs
phosphorylation. Additionally, the presence of phenols, terpenes, or
other phytocannabinoids enhance the therapeutic activity of CBD,
defined as entourage effects. In addition, cannabis extract inhibits
the production of IL-8, matrix metallopeptidase (MMP)-9, and vascular
endothelial growth factor (VEGF), an effect not detected with CBD
alone, in skin cells. Other non-psychoactive cannabinoids, including
CBC and CBN, also showed substantial in vivo anti-inflammatory
responses. On the other hand, monoterpenes such as α- and
β-pinene, myrcene, and limonene have been also reported to
possess substantial anti-inflammatory properties.
"Regarding neuroinflammation, both CBD and THC have protective effects
through the activation of NF-𝜅B as well as the inhibition of Toll like
receptor (TLR4). Indeed, in a vitro model of LPS-stimulated
neuroinflammation, CBD suppresses the release of TNF-α,
IL-1β, and IL-6 through the inhibition of NF-𝜅B phosphorylation
and the concomitant activation of COX and iNOS. In addition, THC
treatment selectively reduces CD8+ T cell response accompanied by
inhibition of IL-6 release. The combination of THC and CBD seems to be
the most potent anti-inflammatory drug able to inhibit the T helper
response as well as CD4+ T response in a mouse model of multiple
sclerosis (MS).
"Beyond the regulation of inflammation, phytocannabinoids can prevent
proliferation, metastasis, and angiogenesis, as well as induce
apoptosis in a variety of cancer cell types. Treatments with CBC and
THC or CBD led to cell cycle arrest and cell apoptosis. Additionally,
CBC and THC or CBD treatments inhibit bladder urothelial carcinoma
cell migration and affected F-actin integrity.
"Beyond the actions of CBC, THC, and CBD on different pathways
involved into development of cancer cell types, also cannabigerol
(CBG), cannabidivarin (CBDV), cannabinol (CBN), cannabivarin (CBV),
and tetrahydrocannabivarin (THCV) have showed a role as anti-cancer
for different cells line."

[5796]
For Anis et al (2025) "Targeting bladder cancer: Potent anti-cancer
effects of cannabichromene and delta-9-tetrahydrocannabinol-rich
Cannabis sativa strains"
"A large retrospective epidemiological study revealed that cannabis
use among the general population may be associated with a reduced
incidence of bladder cancer. This association remained unexplained. We
have previously shown that cannabis-derived compounds have cytotoxic
synergistic activity against UC cell lines. Our work demonstrated a
consistent inhibitory effect of cannabichromene (CBC) and
delta-9-tetrahydrocannabinol (THC) at well-defined concentrations and
ratios on UC cell proliferation, migration, cell cycle arrest, and
treatment-induced apoptosis of UC cells."

[5797]
Apparently the worst thing that can happen to you if cannabinoids make
you better is that you will actually feel that you are better. Having
such feelings is very much against the trend of modern western
pharmaceutical interventions.
"One of the major challenges for future research is designing
synthetic cannabinoids that elicit positive effects of CB1 activation
in peripheral neurons and in specific brain regions, but without
significant cognitive effects."
...say Scott et al in an otherwise enthusiastic article loaded
heavily in favour of synthetic cannabinoids. But it remains
inescapable that a plant got there first. [4027]
And how or why these "positive effects of CB1 activation" must take
place without cognitive effects is not explained. An analogy:
"Alcohol free pubs allow people to gather, and you can laugh, spill
things, or fall over, leading to neuronal stimulation, without the
significant cognitive effects caused by alcohol."
Indeed no pro-alcohol researchers claiming red wine has health
benefits have ever claimed that it ought to be alcohol-free red wine.
So the feelgood benefits of wine and those of cannabis are strangely
set apart for no discernable reason. Except of course, the reason that
you won't get any money for supporting cannabis euphoria. Thus
Doboviek et al are able to state in "Cannabinoids and triple-negative
breast cancer treatment" (2024):
"Cannabinoids show antitumor activity in most preclinical studies in
TNBC models and do not appear to have adverse effects on
chemotherapy."
and
"The antitumor effect of THC on breast cancer cell lines was
documented. Among the tumor cells, those with a more aggressive
phenotype, including the MDA-MB-231 cell line, were more sensitive to
THC."
and
"The antitumor efficacy of pure THC was compared with that of an
herbal drug preparation of fresh cannabis flowers containing a variety
of cannabinoids and terpenes. The herbal drug preparation contained
THC and CBG, but no CBD, and was more effective than pure THC in
producing antitumor responses in cell cultures and animal models of
various breast cancer subtypes, including the TNBC subtype (MDA-MB-231
and SUM159 cell lines)."
and
" The herbal drug preparation was significantly more potent than pure
cannabinoid (the same dose of THC was administered)."
As for reducing the harms of the official cures:
"Importantly, the major cannabinoids (THC, CBD, and cannabinol) and
their metabolites found in the plasma of cannabis users can inhibit
several P450 enzymes, including CYP2B6, CYP2C9, and CYP2D6, and cause
pharmacokinetic interactions between these cannabinoids and
xenobiotics that are extensively metabolized by these enzymes. There
is evidence that cannabinoids alleviate peripheral neuropathic pain
caused by chemotherapy and prevent doxorubicin-induced cardiomyopathy.
Both are side effects of taxane and anthracycline chemotherapy, which
is frequently used in TNBC."
While it may seem important that
"Cannabis use correlated with a significant reduction in time to
tumor progression and OS [overall survival]. Cannabis users were
associated with a lower number of immune-related adverse events
(iAEs)."
The researchers do not seem to think much of the placebo effect or
belief:
"Many patients take cannabinoids in the belief that this will help
cure their disease, although there is currently no clinical data to
support this claim in breast cancer patients, including TNBC. A survey
of breast cancer patients found that 42% of survey participants used
cannabis to treat symptoms and about half of these participants
believed that cannabis could treat the cancer itself."
But it is as all this never existed when we learn that, for some
reason, CBD
"...is a non-psychoactive substance and therefore a potential
therapeutic agent."
https://www.frontiersin.org/journals/immunology/articles/10.3389/fimmu.2024.1386548/pdf
[3427]
Many researchers have plodded on obediently with this "rather die
than get high" mentality (RDTGH). Thus, in a study of
phytocannabinoids' effects upon calcium fluxes dependent on transient
vanilloid receptor type 1 only
"Cannabinoids other than the highly psychoactive tetrahydrocannabinol
(THC) that rank order in abundance directly below THC in Cannabis
chemotypes were selected for analysis. Cannabidiol (CBD), Cannabinol
(CBN) and the minor cannabinoids Cannabidiolic Acid (CBDA),
Cannabidivarin (CBDV), Cannabichromene (CBC), Cannabigerol (CBG),
Cannabigerolic Acid (CBGA) were selected."
They writhe around in a twisted mess of self-interest and
legality:
"Cannabinoids are of significant interest in the context of
'medicinal' [note the sarcastic quotes] Cannabis use. Pain is one of
the most common indications for which medical marijuana is legally
allowed to be prescribed and is demanded by patients."
According to their thinking, which is apparently
anti-euphoria:
"The psychoactive nature of THC-containing whole chemovars of
Cannabis, which is typically the available form of the drug in
dispensaries, leads to regulatory issues and adverse
side-effects."
A key assumption is that a pain-free existence and happiness are
mututally exclusive - it sounds like a religious idea. You can see
what they are trying to do is like alcohol-free beer or decaf. We
could go on to take vitamin pills instead of eating vegetables. We
have meat-free protein, but perhaps what we really need is a scientist
to design protein-free meat.
"The distinct response profiles of the different cannabinoids that we
observe also provide the possibility of fine-tuning or shaping
desirable responses using cannabinoid mixtures. At the level of the
sensory neuron bundles, the fact that cannabinoids appear to
discriminate between TRP receptors and that the receptors in turn
respond distinctively to the compounds, again offers the potential for
rational design of therapeutic mixtures."
Their 2019 ideas for the future are not much use if you wanted pain
relief in 2012 or 1991, are they?
While they continue to tinker around, there's this plant, isn't
there?

Other researchers are more understanding to THC and other CCx.
Consider Reva et al (2025) who examined "Comparative Effects of THC
and CBD on Chemotherapy-Induced Peripheral Neuropathy: Insights from a
Large Real-World Self-Reported Dataset":
"Chemotherapy-induced peripheral neuropathy (CIPN) is a common
dose-limiting adverse effect of various chemotherapeutic agents.
Previous work demonstrated that cannabis alleviates symptoms of
oxaliplatin-induced CIPN. To evaluate the effects of cannabis
components, cannabidiol (CBD) and tetrahydrocannabinol (THC), on
CIPN-related symptoms. Methods: We reviewed a patient-reported
outcomes dataset from 'Tikun Olam,' a major medical cannabis provider.
Of 1493 patients, 802 reported at least one CIPN symptom at baseline,
including a burning sensation, cold sensation, paresthesia (prickling)
and numbness, and 751 of them met the study inclusion criteria.
Patients were categorized into THC-high/CBD-low and CBD-high/THC-low
groups. Symptom changes after six months of cannabis use were analyzed
using K-means clustering and logistic regression, incorporating
interactions between baseline symptoms and THC and CBD doses. Linear
regression assessed changes in activities of daily living (ADL) and
quality of life (QOL). Results: Both groups reported symptom
improvement. The THC-high group showed significantly greater
improvement in burning sensation and cold sensation (p = 0.024 and p =
0.008). Improvements in ADL and QOL were also significantly higher in
the THC group (p = 0.029 and p = 0.006). A significant interaction
between THC and CBD was observed for symptom improvement (p <
0.0001). Conclusions: Cannabis effectively reduces CIPN symptoms and
improves QOL and ADL. Higher THC doses were more effective than lower
doses, with combined CBD and THC doses yielding greater symptom
relief."

Is there any evidence Jan Smuts knew anything about insulin in 1924?
Here's an ngram.

Smuts was a keen reader, so he might have come across it. Would he
have associated it in his mind with dagga? This proposition is
impossible to prove. Smuts' contributions to the field of physiology
are more of a philosophical nature:
"Also at that time, biological science was evolving away from
materialism as the pure physiology model of nineteenth century. So,
while psychologys original aim was to explain all mental activity by
mechanical principles with its failure on the physiological level
biochemistry as the familiar partner of mechanistic physiology began
pointing in another, relativistic-biologic direction. Escaping this
irrelevance, biochemistry better and better differentiated living from
dead matter and, as a result, scientific interest turned to
investigating living material. These investigations produced questions
more fundamental to human life; those about organic material and about
its biological phenomena, for example the process of regeneration in
nature (e.g., tapeworm survival after vivisection) and the healing
process in general. What grew to be a revolution in biology joined
phenomenology in conceptualizing organisms as unities. As Smuts (1926)
had conjectured philosophically and Goldstein (1934/1963) contended
neurologically, maintenance of the integrity of the whole cannot be
deduced biochemically. Each tissue and every organ seem to follow a
law of the total organism."
Though he was probably interested in battle wounds, the Defendant
could find no evidence Smuts dug deeply into the small stuff, like
insulin. In the Boer War, if you got shot in a limb, they chopped it
off. If you were shot anywhere else, you died.
In fact the idea of lipid cell membranes began in December 1925, with
a paper by Gortel and Grendel at the University of Leiden.
"It is clear that all our results fit in well with the supposition
that the chromocytes are covered by a layer of fatty substances that
is two
molecules thick."
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2130960/pdf/439.pdf
[2539]
Theories of cell membrane structure continued through the prohibition
era and various iterations of the cannabis legislation:
"Then in the 1950s, Robertson proposed a three-layer structure, where
two layers of proteins were attached to a lipid layer in the middle. A
few years later Lenard and Singer suggested a revised model, where the
proteins were now allowed to span a lipid bilayer structure. This
picture was yet considered incomplete, and in 1972 Singer and Nicolson
proposed the famous 'fluid mosaic' model that is nowadays generally
known also as the SingerNicolson model."
But even by 2019, many mysteries were unresolved:
"Biological membranes are everywhere. All our cells are surrounded by
a biological membrane. So also are the tiny organelles such as the
nucleus that contains our genetic code and the endoplasmic reticulum
that synthesizes most of our proteins. Biological membranes keep us
alive when they transfer oxygen from our lungs to our bloodstream.
Biomembranes also control our mood, because they host the receptors of
signaling molecules such as dopamine in our brain.
"It is quite intriguing that membranes can play such crucial roles in
maintaining life, yet these membranes are basically just soft, few
nanometers thick lipid interfaces. However, the more closely one looks
at them, the more complex they turn out to be. It is quite justified
to note that despite about 100 years of research, we still do not
understand exactly what biological membranes really look
like."
https://pubs.acs.org/doi/10.1021/acs.chemrev.8b00538
[2531]
So obviously Smuts did not know anything about that?
Smuts was already 55 by 1925. Germ layer theory was wiped out in
1926. Endosymbiosis in evolutionary theory was proposed in 1927.
Penicillin arrived in 1928. ATP was discovered in 1929. Vitalism had
died by the end of the 20s. Essential fatty acids arrived in
1929/1930. Human metabolism was far removed from anything going on in
Smuts' head about cannabis.

[2129]
Here's another example of woo woo in the way.
Jan Smuts or the League of Nations could not have known in 1924 that
"The endocannabinoid system has emerged as a key regulatory signaling
pathway in the pathophysiology of alcohol-associated liver disease
(ALD). More than 30 years of research have established different roles
of endocannabinoids and their receptors in various aspects of liver
diseases, such as steatosis, inflammation, and fibrosis."
But what is curious is how the introduction goes on. For, they
warn
"However, pharmacological applications of the endocannabinoid system
for the treatment of ALD have not been successful because of
psychoactive side effects, despite some beneficial effects."
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8496755/
[2048]
Two things should strike the Court as curious about this.
Firstly, nowhere do they query the role of alcohol in
alcohol-associated liver disease. For these authors these liver
diseases are alcohol-associated because it says so in the name. It is
incontrovertibly true that alcohol has gotten the ALD patients into
this disease spectrum.
Secondly, their complaint about euphoria is entirely directed towards
the putative medicaments for ALD.
Why is no one suggesting making alcohol non-euphoric?
Rather than trying to cure liver disease after you have drunk the
legal drugs, why not make them ineffective? You could limit the
alcohol content to 0.2%. You could make it no crime to buy but illegal
to sell. Or you could make a complicated medical model concentrating
the supply into the hands of a coterie of doctors or therapists,
thickening Slovenia's starchy rentier economy. Why not do
that?
Why, given the euphoria potential for alcohol, is that not reason
enough alone to stop people being attracted to it in the first place?
And yet for someone who doesn't want to be a fat alcoholic diabetic
with cancer, these kind of measures are in effect?
The euphoria of alcohol is brief, and associated with a low BAC. Why
are the scientists closing the barn door after the horse has bolted?
So we have, essentially a "good euphoria" in the past which has made
all these people ill, and a "bad euphoria" which - like most anxiety -
concerns the future, specifically the future for patentable
pharmaceuticals that can target the endocannabinoid system without the
alcohol victim losing his shit. The Defence fears this is much more of
a concern around the former reason than the latter. "Bad euphoria" may
be added to the list of Prohibition's friends.
Later they come back to this "limitation" of drugs that make you
happy while fixing your alcohol-ravaged liver:
"The endocannabinoid system has been observed in both the hepatocytes
and various nonparenchymal cells in the liver, in which the
endocannabinoid production and its receptor activation may contribute
to the development of a spectrum of ALD, ranging from simple alcoholic
steatosis to more severe forms such as steatohepatitis and fibrosis.
Therefore, understanding the precise physiology of the endocannabinoid
system in the liver and unveiling the mechanism underlying the
association between ALD progression and hepatic endocannabinoid
signaling seem to bear a paramount significance for the advancement of
ALD treatment, as well as for the treatment of other chronic liver
diseases (e.g., NAFLD, viral hepatitis). Moreover, developing
efficacious and highly selective cannabinoid receptormodulating drugs
could be a major breakthrough in the treatment of ALD.
"However, efforts to develop second- and third-generation CB1R
antagonists must overcome the complications caused by the first
generation of CB1R antagonists, which were able to penetrate the
blood-brain barrier and produced critical psychiatric side
effects."
and
"However, pharmacological applications of the endocannabinoid system
for the treatment of ALD have not been successful because of
psychoactive side effects, despite some beneficial effects."
Meanwhile findings continue to demonstrate the relative uselessness
in many pathways of legally-available CBD products and point towards
whole-plant effectiveness due to the so-called entourage
effect.
University of Michigan researchers with the company Gb Sciences Inc.
evaluated the effect of selected terpenes and cannabinoids on human
primary leukocytes.
The terpenes evaluated included α-pinene, trans-nerolidol,
D-limonene, linalool and phytol. The three immune cell types were
chosen based on their important roles in modulating the inflammatory
cascade.
The study found that the most efficient cannabinoid was THC, followed
by CBDV (Cannabidivarin), CBG (Cannabigerol), CBC (Cannabichromene),
CBN (Cannabinol) and finally, CBD.
The terpene α-Pinene showed the greatest immune modulating
activity from the group followed by linalool, phytol and
trans-nerolidol. Limonene had no effect which was attributed to some
terpenes being highly selective or targeting a single cell
type.
Peripheral Blood Mononuclear Cells are any peripheral blood cell
having a round nucleus, and include lymphocytes (T cells, B cells, and
NK cells), monocytes, and dendritic cells. In humans, the frequencies
of these populations vary across individuals, but typically,
lymphocytes are in the range of 7090 %, monocytes from 10 to 20 %,
while dendritic cells are rare, accounting for only 12 %.
"Human PBMC were pretreated with each compound, individually, at
concentrations extending from 0.001 to 10 μM and then stimulated
with CpG (plasmacytoid dendritic cell), LPS (monocytes), or
anti-CD3/CD28 (T cells). Proliferation, activation marker expression,
cytokine production and phagocytosis, were quantified. Of the 21
responses assayed for each compound, cannabinoids showed the greatest
immune modulating activity compared to their vehicle control.
Delta-9-tetrahydrocannabinol possessed the greatest activity affecting
11 immune parameters followed by cannabidivarin, cannabigerol,
cannabichromene, cannabinol and cannabidiol. α-Pinene showed the
greatest immune modulating activity from the selected group of
terpenes, followed by linalool, phytol, trans-nerolidol. Limonene had
no effect on any of the parameters tested. Overall, these studies
suggest that selected cannabis-derived terpenes displayed minimal
immunological activity, while cannabinoids exhibited a broader range
of activity."

Some consider the effect to be additive, rather than synergistic or
multiplicative in nature. Discussing D9-THC and terpene interactions
in 2021, Liktor-Busa et al at the Department of Pharmacology of the
University of Arizona summarise:
"These studies suggest that although terpenes may have significant
antinociceptive properties (discussed above), it is likely that these
properties are not modulated through direct interactions at
cannabinoid receptors, nor does it appear they will modify
antinociception induced by cannabinoids such as D9 -THC. However,
these studies are limited and do not rule out an interaction
definitively."
As for CBD, evidence is "limited":
"An in vivo study observing the difference between CBD, D9 -THC, or a
C. sativa high-CBD extract (containing other phytocompounds)
demonstrated that the antinociceptive properties of the CBD extract
were greater than CBD or D9 -THC alone in a chronic constriction
injury model of neuropathic pain (Comelli et al., 2008). Furthermore,
combining pure CBD and pure D9 -THC in a similar ratio to the high-CBD
extract could not recapitulate the greater effect of the extract,
suggesting other noncannabinoid contributions. They also state that
although a single dose of CBD could not alleviate the neuropathic
pain, a single dose of the CBD extract could reduce thermal
hyperalgesia comparable to D9 -THC, but data were not provided. The
antinociceptive effects of the CBD extract could be blocked with a
TRPV1 antagonist but not a CB1 or CB2 antagonist."

Tomko et al at Dalhousie University in Halifax, Canada found
"Anti-cancer properties of cannflavin A and potential synergistic
efects with gemcitabine, cisplatin, and cannabinoids in bladder
cancer" (2022):
"Cell viability of bladder cancer cell lines was affected in a
concentration-dependent fashion in response to cannflavin A, and its
combination with gemcitabine or cisplatin induced differential
responses-from antagonistic to additive-and synergism was also
observed in some instances, depending on the concentrations and drugs
used. Cannflavin A also activated apoptosis via caspase 3 cleavage and
was able to reduce invasion by 50%. Interestingly, cannflavin A
displayed synergistic properties with other cannabinoids like
Δ9-tetrahydrocannabinol, cannabidiol, cannabichromene, and
cannabivarin in the bladder cancer cell lines."

Cannabis components such as the cannflavins may be manipulable using
different artificial light and cultivars:
"Increased solar UV radiation results in higher CBDA, terpene, and
cannaflavin [sic] content in the hemp variety Kompolti (Giupponi et
al., 2020). Notably, UV radiation sources used in both studies had
relatively broad spectra, compared to electrical UV radiation sources,
such UV-discharge lamps and light-emitting diodes (LEDs). It is
unknown if there is was an interactive effect between UV-A (315380 nm)
and UV-B radiation, as a high percentage of UV-A radiation was present
in both the UV-B and control light treatments (Mirecki and Teramura,
1984; Lydon et al., 1987; Giupponi et al., 2020). A subsequent study
examined the impact of UV-A radiation on cannabinoid accumulation, and
reported increased cannabinoid levels other than Δ9-THC
(Magagnini et al., 2018). Low percentages of UV-A radiation (2%) from
full-spectrum LED arrays induced an increase of several cannabinoids,
including CBD, CBG, Δ9-THC, and tetrahydrocannabivarin (THCV),
compared to a high pressure sodium (HPS) lamp that contained 1% of
UV-A radiation (Magagnini et al., 2018)."
Yet by 2021, according to "Cannabinoids and Terpenes: How Production
of Photo-Protectants Can Be Manipulated to Enhance Cannabis sativa L.
Phytochemistry" the pathway(s) by which cannflavins are produced in
the plant was still a matter of debate.

Brousseau et al also offer a "simplified overview" of the effect of

de Christo Scherer et al found a dose-dependent effect in the "Wound
healing activity of terpinolene and α-phellandrene by
attenuating inflammation and oxidative stress in vitro" (2019). As
they explain:
"Terpenoids represent the oldest and most diverse class of secondary
metabolites formed from five-carbon isoprene units called isoprenoids.
They represent a highly diversified group of naturally occurring
organic compounds, and more than 30,000 different natural terpene
metabolites were identified. In plants, terpenoids have a multitude of
ecological and physiological functions. They chemically defend against
insects and environmental stress and are involved in the repair
mechanism of wounds and injuries."
and
"In summary, the results of the present study showed that terpinolene
and α-phellandrene, which share similar chemical
characteristics, exhibited similar wound healing properties. Using
cell-based assays, both compounds effectively stimulated proliferation
and migration of fibroblasts, protected macrophages against cellular
oxidative damage, and suppressed the production of pro-inflammatory
cytokines (IL-6 and TNF-α) and NF-κB activity."

According to Susanto et al (2024) phellandrene, found in several
herbs, has a synergestic antiproliferative effect on cancer cells with
5-fluorouracil. HT-29 is a human colorectal adenocarcinoma cell line
with epithelial morphology, sensitive to 5-FU.
"The combination of 5-FU and α-PA had a synergistic inhibitory
effect on cell viability, as determined by assessing the combination
index value. Bax protein expression levels were higher in the 50, 100
or 250 M α-PA combined with 5-FU groups compared with those in
the 5-FU alone group (P<0.05). By contrast, Bcl-2 protein
expression levels and mitochondrial membrane potential (MMP,
ΔΨm) were lower in the 100 or 250 M α-PA combined with
5-FU groups than those in the 5-FU alone group (P<0.05). In
addition, hexokinase-2 (HK-2) protein expression levels were lower in
the 50, 100 or 250 M α-PA combined with 5-FU groups than those
in the 5-FU alone group (P<0.05). Compared with 5-FU alone, after
HT-29 cells were treated with 50, 100 or 250 M α-PA combined
with 5-FU, the mRNA expression levels of extrinsic-induced apoptotic
molecules, including caspase-8 and Bid, were higher (P<0.05).
Treatment with 50, 100 or 250 M α-PA combined with 5-FU also
increased the mRNA expression levels of cytochrome c, caspase-9 and
caspase-3, regulating intrinsic apoptosis (P<0.05). These results
showed that α-PA and 5-FU had a synergistic effect on reducing
the viability of human colon cancer HT-29 cells by inducing extrinsic
and intrinsic apoptosis pathways."

Ten years earlier, Slovenia's alcohol-worshippers could have learned
from Hsieh et al (2014) about "Induction of necrosis in human liver
tumor cells by α-phellandrene":
"Human liver tumor (J5) cells were incubated with α-PA and
analyzed for cell cycle distribution, expression of Bax, Bcl-2, poly
(ADP-ribose) polymerase (PARP) protein, and caspase-3 activity of J5
cells, and levels of nitric oxide (NO) production, lactate
dehydrogenase (LDH) leakage, and ATP depletion were also analyzed in
this study. Results found that α-PA significantly (P < 0.05)
decreased the cell viability of J5 cells after 24-h treatment. The
cell cycle distribution, Bax, Bcl-2, PARP protein levels, and
caspase-3 activity of J5 cells did not change for 24 h after treatment
with 30 μM α-PA. Reactive oxygen species levels significantly
increased, mitochondrial membrane potential levels significantly
decreased when J5 cells were treated with 30 μM α-PA for 24 h
(P < 0.05). Thirty μM α-PA significantly (P < 0.05)
increased the necrotic cell number, NO production, LDH leakage, and
ATP depletion after 24 h of incubation. These results suggest that
α-PA induced J5 cell necrosis but not apoptosis, and
α-PA-induced necrosis possibly involved ATP depletion."

Aydin et al (2013) investigated "Anticancer and antioxidant
properties of terpinolene in rat brain cells":
"Terpinolene (TPO) is a natural monoterpene present in essential oils
of many aromatic plant species. Although various biological activities
of TPO have been demonstrated, its neurotoxicity has never been
explored. In this in vitro study we investigated TPO's
antiproliferative and/or cytotoxic properties using the
3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyltetrazolium bromide (MTT)
test, genotoxic damage potential using the single-cell gel
electrophoresis (SCGE), and oxidative effects through total
antioxidant capacity (TAC) and total oxidative stress (TOS) in
cultured primary rat neurons and N2a neuroblastoma cells.
Dose-dependent effects of TPO (at 10 mg L(-1), 25 mg L(-1), 50 mg
L(-1), 100 mg L(-1), 200 mg L(-1), and 400 mg L(-1)) were tested in
both cell types. Significant (P<0.05) decrease in cell
proliferation were observed in cultured primary rat neurons starting
with the dose of 100 mg L(-1) and in N2a neuroblastoma cells starting
with 50 mg L(-1). TPO was not genotoxic in either cell type. In
addition, TPO treatment at 10 mg L(-1), 25 mg L(-1), and 50 mg L(-1)
increased TAC in primary rat neurons, but not in N2a cells. However,
at concentrations above 50 mg L(-1) it increased TOS in both cell
types. Our findings clearly demonstrate that TPO is a potent
antiproliferative agent for brain tumour cells and may have potential
as an anticancer agent, which needs to be further studied."
As for genotoxicity:
"In vitro exposure to TPO of either cell type did not result in comet
formation, regardless of the dose, indicating the non-genotoxic nature
of TPO (Figure 2)."
For total antioxidant capacity (in Trolox Equivalent / mmol
L-1)...
"TPO at the concentrations of 100 mg L-1 and 200 mg L-1 did not
affect TAC in primary rat neuron cells, increased it signifi cantly at
the concentrations of (10, 25, and 50) mg L-1, and decreased it
signifi cantly at the highest concentration (400 mg L-1) compared to
control (Table 1). Similarly, in N2a neuroblastoma cells TPO (at 10 mg
L-1 and 25 mg L-1) did not change TAC levels, but decreased them
signifi cantly at ((50, 100, 200, and 400) mg L-1, compared to
control."

Reminding us that "Cannabis sativa has been utilized for medical
purposes for thousands of years. It continues to be recognized as a
plant with an extensive variety of medicinal and nutraceutical uses
today," a paper on the discovery of "New Cannabinoids and Chlorin-Type
Metabolites from the Flowers of Cannabis sativa L.: A Study on Their
Neuroblastoma Activity" by Nguyen et al from Korea reported in April
2025:
"Eleven compounds were isolated from the flowers of C. sativa,
including two new compounds, namely cannabielsoxa (1),
132-hydroxypheophorbide c ethyl ester (2), and six known cannabinoids
(611), together with the first isolation of chlorin-type compounds:
pyropheophorbide A (3), 132-hydroxypheophorbide b ethyl ester (4), and
ligulariaphytin A (5) from this plant. The results also demonstrated
that cannabinoid compounds had stronger inhibitory effects on
neuroblastoma cells than chlorin-type compounds. Conclusions: The
evaluation of the biological activities of compounds showed that
compounds 410 could be considered as the potential compounds for
antitumor effects against neuroblastomas. This is also highlighted by
using docking analysis. Additionally, the results of this study also
suggest that these compounds have the potential to be developed into
antineuroblastoma products."

Sztolsztener et al (2023) describe the "Concentration-Dependent
Attenuation of Pro-Fibrotic Responses after Cannabigerol Exposure in
Primary Rat Hepatocytes Cultured in Palmitate and Fructose
Media":
"Hepatic fibrosis is a consequence of liver injuries, in which the
overproduction and progressive accumulation of extracellular matrix
(ECM) components with the simultaneous failure of matrix turnover
mechanisms are observed. The aim of this study was to investigate the
concentration dependent influence of cannabigerol (CBG, Cannabis
sativa L. component) on ECM composition with respect to transforming
growth factor beta 1 (TGF-β1) changes in primary hepatocytes with
fibrotic changes induced by palmitate and fructose media. Cells were
isolated from male Wistar rats livers in accordance with the two-step
collagenase perfusion technique. This was followed by hepatocytes
incubation with the presence or absence of palmitate with fructose
and/or cannabigerol (at concentrations of 1, 5, 10, 15, 25, 30 M) for
48 h. The expression of ECM mRNA genes and proteins was determined
using PCR and Western blot, respectively, whereas media ECM level was
evaluated using ELISA. Our results indicated that selected low
concentrations of CBG caused a reduction in TGF-β1 mRNA
expression and secretion into media. Hepatocyte exposure to
cannabigerol at low concentrations attenuated collagen 1 and 3
deposition. The protein and/or mRNA expressions and MMP-2 and MMP-9
secretion were augmented using CBG. Considering the mentioned results,
low concentrations of cannabigerol treatment might expedite fibrosis
regression and promote regeneration."

Smith et al examined the chemical reality of THC-dominant,
CBD-dominant and balanced THC:CBD strains and found the present labels
inadequate. 2022's "The phytochemical diversity of commercial Cannabis
in the United States" found that CBD-dominant and THC:CBD balanced
products "displayed myrcene-dominant terpene profiles compared to
THC-dominant samples."
"Mapping the chemical diversity of the Cannabis-derived products
consumed by millions of people has important implications for consumer
health and safety, such as identifying the number of chemically
distinct types of Cannabis being consumed in legal markets. This may
be consequential if distinct chemotypes are later determined to cause
reliably different effects."
The researchers analyzed 89,923 different samples of loose-leaf
cannabis from six certified testing laboratories in the U.S.
states.
"84.5 percent of CBD-dominant samples had total THC levels above 0.3
percent, the threshold used to legally define hemp in the U.S.," noted
the researchers. "This indicates that a substantial fraction of
CBD-dominant cannabis would not meet the legal definition of hemp in
the U.S.," indicating a collision between the biochemical reality of
this plant species and the regulatory framework wrapped around it in
the United States.
The most common terpenes present in the flower samples were
beta-caryophyllene (BCP), limonene, and myrcene (the most common
terpene in cannabis, according to other studies). "In most cases,
individual terpenes were rarely present at more than 0.5 percent
weight."
and the research found that THC-dominant cannabis products (Type I)
"displayed significantly higher levels of [terpene] diversity than
both balanced THC:CBD [Type II] and CBD-dominant products [Type III]."
The study found that the labels of indica, sativa, and hybrid did not
correspond well to the terpene profiles of the samples. "It is likely
that a sample with the label 'indica' will have an indistinguishable
terpene composition as samples labelled 'sativa' or 'hybrid.'"
The scientists determined that a simple product labeling system "in
which THC-dominant samples are labelled by their dominant terpene"
would better serve both the industry and consumers and be "better at
discriminating samples than the industry-standard labelling system" of
indica, sativa, and hybrid.
The study found "a large amount of variability in mean consistency
scores across all 'strain names.'" Sometimes, the chemical makeup of a
strain featured relatively strong consistency across the data set. For
example, 96 percent of flower samples labeled to be the strain Purple
Punch feature strong levels of beta-caryophyllene and limonene, while
only 62.5 percent of products labeled Tangie fell into a single
cluster.
The study identified three cluster groups that each are dominated by
a different terpene pair.
Cluster I: Relatively high levels of beta-caryophyllene and
limonene
Cluster II: Relatively high levels of myrcene and pinene
Cluster III: Relatively high levels of myrcene and terpinolene
"Samples across these clusters display similar total THC
distributions, while Cluster III is associated with modestly higher
CBG levels," summarized the study's authors.
The scientists concluded that their study results "provide new
possibilities for systematically categorizing commercial cannabis
[products] based on chemistry, the design of preclinical and clinical
research experiments, and the regulation of commercial cannabis
marketing."
"The general approach we have used in this study can serve as a basic
guide for cannabis product segmentation and classification rooted in
product chemistry," they wrote. "Consumer-facing labelling systems
should be grounded in such an approach so that consumers can be guided
to products with reliably different sensory and psychoactive
attributes."

government-approved strain names like "Bureaucrat Grey" and "Reverend

For some researchers, the major cannabinoids are relatively
uninteresting:
"In this study we provide the first comprehensive overview of the
effects of whole-plant Cannabis extracts and various pure cannabinoids
on store-operated calcium (Ca2+) entry (SOCE) in several different
immune cell lines. Store-operated Ca2+ entry is one of the most
significant Ca2+ influx mechanisms in immune cells, and it is critical
for the activation of T lymphocytes, leading to the release of
proinflammatory cytokines and mediating inflammation and T cell
proliferation, key mechanisms for maintaining chronic pain. While the
two major cannabinoids cannabidiol and
trans-Δ9-tetrahydrocannabinol were largely ineffective in
inhibiting SOCE, we report for the first time that several minor
cannabinoids, mainly the carboxylic acid derivatives and particularly
cannabigerolic acid, demonstrated high potency against SOCE by
blocking calcium release-activated calcium currents. Moreover, we show
that this inhibition of SOCE resulted in a decrease of nuclear factor
of activated T-cells [NFAT] activation and Interleukin 2 production in
human T lymphocytes. Taken together, these results indicate that
cannabinoid-mediated inhibition of a proinflammatory target such as
SOCE may at least partially explain the anti-inflammatory and
analgesic effects of Cannabis."
You should know
"The release of proinflammatory mediators is regulated by
calcium-dependent signaling mechanisms that activate several
transcription factor pathways, including NFAT, nuclear factor kappa B
(NF-KB), and cAMP response element-binding protein."

Musetti et al, discussing the anti-atherosclerotic effects of three
cannabis extracts, point out that:
"...the effect of the extracts was greater than the addition of the
inhibitory effect of the individual cannabinoid components. This
synergy or more than additive effect could be explained by the
entourage effect. The term was first coined by Ben-Shabat et al. to
explain that non-active metabolites potentiated the effect of the
endocannabinoid 2-arachidonoylglycerol. Individual components could
exhibit additive effects, their combined impact is simply the sum of
their individual effects; antagonistic interactions, or synergistic
interactions when compounds produce an effect surpassing the sum of
their individual contributions. Cannabinoid-cannabinoid interactions,
cannabinoid-terpene, and terpene-terpene interactions could account
for intra or inter entourage effects. Our observation that the
extracts as a whole exhibit stronger inhibition than the sum of the
effect of the component cannabinoids supports either an entourage
effect or the additive effect of a low-abundance component with potent
bioactivity.

addition, we used the phorbol 12-myristate 13-acetate (PMA)-induced

kinase C, stimulates HMC-1 cells to exhibit characteristis of tissue
mast cells including degranulation, surface antigen profile, and

and
"Under stress conditions such as alcohol abuse, the level of
histamine is elevated, which increases acid production, thus inducing
gastritis. Therefore, we investigated the inhibitory effect of
α-humulene on histamine release using HMC-1 cells. When
stimulated with compound 48/80 or PMA, HMC-1 cells release histamine.
Here, we showed that α-humulene significantly decreased
histamine secretion without cellular toxicity. Previous studies have
shown that both intracellular calcium and cAMP act as important
modulators during the degranulation of HMC-1 cells. When mast cells
are stimulated, calcium channels rapidly open at the membrane, and a
large amount of calcium enters the cytoplasm. Moreover, activated
phospholipase C converts phosphatidylinositol 4,5-bisphosphate (PIP2)
to inositol 1,4,5-trisphosphate (IP3), which binds to the IP3-gated
calcium channel of the mast cell endoplasmic reticulum (ER). Then, a
large amount of calcium stored in the ER is released into the
cytoplasm. To investigate the underlying molecular mechanism of the
antihistamine effect of α-humulene, the following experiment was
conducted. First, we examined the changes in calcium influx using the
fluorescent dye, Fluro-2/AM. Compared to compound 48/80-treated cells,
α-humulenetreated cells showed lower levels of intracellular
calcium. Next, we investigated the changes in cAMP, because
intracellular cAMP increases to inhibit the release of mediators in
mast cell. Similar to curcumin (positive control), α-humulene
increased intracellular cAMP levels, which resulted in the inhibition
of histamine release. Taken together, α-humulene inhibits
histamine secretion by regulating intracellular calcium and cAMP
concentrations without any cytotoxicity."

In "Terpenes from Cannabis sativa Induce Antinociception in Mouse
Chronic Neuropathic Pain via Activation of Spinal Cord Adenosine A2A
Receptors" by Schwarz et al (2024) five cannabis terpenes were tested
on pain in mice using a Chemotherapy-Induced Peripheral Neuropathy,
and lipopolysaccharide-induced Acute Inflammatory Models:
"Terpenes are small hydrocarbon compounds that impart aroma and taste
to many plants, including Cannabis sativa. A number of studies have
shown that terpenes can produce pain relief in various pain states in
both humans and animals. However, these studies were methodologically
limited and few established mechanisms of action. In our previous
work, we showed that the terpenes geraniol, linalool, β-pinene,
αhumulene, and β-caryophyllene produced cannabimimetic
behavioral effects via multiple receptor targets. We thus expanded
this work to explore the efficacy and mechanism of these Cannabis
terpenes in relieving chronic pain. We first tested for
antinociceptive efficacy by injecting terpenes (200 mg/kg, IP) into
male and female CD1 mice with chemotherapy-induced peripheral
neuropathy (CIPN) or lipopolysaccharide-induced inflammatory pain,
finding that the terpenes produced roughly equal efficacy to 10 mg/kg
morphine or 3.2 mg/kg WIN55,212. We further found that none of the
terpenes produced reward as measured by conditioned place preference,
while low doses of terpene (100 mg/kg) combined with morphine (3.2
mg/kg) produced enhanced antinociception vs. either alone. We then
used the adenosine A2A receptor (A2AR) selective antagonist
istradefylline (3.2 mg/kg, IP) and spinal cord-specific CRISPR
knockdown of the A2AR to identify this receptor as the mechanism for
terpene antinociception in CIPN. In vitro cAMP and binding studies and
in silico modeling studies further suggested that the terpenes act as
A2AR agonists. Together these studies identify Cannabis terpenes as
potential therapeutics for chronic neuropathic pain, and identify a
receptor mechanism in the spinal cord for this activity."
In the LPS arm
"Mechanical allodynia was produced by LPS in all mice (Figure 2A).
Most terpenes (200 mg/kg, IP) produced significant time-dependent
antinociception over vehicle control; the only exception was
β-pinene, which produced a small, non-significant improvement in
mechanical threshold (Figure 2A). AUC analysis backed up this
conclusion, with geraniol and linalool both producing significant
elevation in AUC over vehicle control (Figure 2B). Much like with CIPN
above, while the other terpenes had non-significant AUC increases, the
mean values were still elevated 5-7 fold over the vehicle mean (Figure
2B). Both data types together suggest that all terpenes except
β-pinene are effective antinociceptive agents in this second,
different pathological pain type."
https://journals.lww.com/pain/fulltext/2024/11000/terpenes_from_cannabis_sativa_induce.16.aspx
[3100]
"'The terpenes were tested individually and compared with morphine.
The research team found that each terpene was successful in reducing
the sensation of pain at levels near to or above the peak effect of
morphine. When the terpenes were combined with morphine, the
pain-relieving effects of all five terpene/morphine combinations were
significantly increased.
"'That was really striking to us, but just because something relieves
pain doesnt necessarily mean its going to be a good therapy,' [lead
researcher John] Streicher said.
"Comparing Terpenes and Opioids
Opioids are often used to treat many types of pain, but they can come
with a host of unwanted side effects. Opioids activate the brains
reward system, which is what can lead to addiction, and can cause
tolerance, a condition that occurs when the body gets used to a
medication and needs increasingly larger doses to have the same
effect. Opioids also can cause respiratory depression, which can lead
to death.
'We looked at other aspects of the terpenes, such as: Does this cause
reward? Is this going to be addictive? Is it going to make you feel
awful?' Streicher said. 'What we found was yes, terpenes do relieve
pain, and they also have a pretty good side effect profile.'
"None of the terpenes had reward liability, making them a low risk
for addiction. Some of the terpenes also did not cause aversive
behaviors, which suggests they could be effective therapeutics without
producing distressing side effects.
"Finally, researchers tested different routes of terpene
administration: injection, oral dosing, and inhalation of vaporized
pure terpenes. They found that when terpenes were given orally or
inhaled, the effects were significantly reduced or absent.
"'A lot of people vape or smoke terpenes as part of cannabis extracts
that are available commercially in states where cannabis use is
legal,' Streicher said 'We were surprised to find that the inhalation
route didnt have an impact in this study, because there are a lot of
at least anecdotal reports saying that you can get the effects of
terpenes whether taken orally or inhaled. Part of the confounding
factor is that terpenes smell quite nice and its hard to disguise that
aroma, so people could be kind of having the psychosomatic
placebo-style effect.'"
Their future aims to exploit this supposedly placebo, anti-rewarding
effect:
"...you could have a combination therapy, an opioid with a high level
of terpene, that could actually make the pain relief better while
blocking the addiction potential of opioids,' Streicher said. 'Thats
what we are looking at now.'"

[3101]
2019's "The heterogeneity and complexity of Cannabis extracts as
antitumor agents" from the University of Haifa, Israel concluded your
chances against cancer are improved with a shotgun effect of natural
cannabinoid combinations compared to single extracts. Nature got it
right again.
"Dr. Baram et al. investigated the effect of various combinations of
cannabis extracts and their effect on 12 different cancers. Results
demonstrated a variable response depending upon the cancer type and
content profile of the specific cannabis extract. Of the 12 cancer
varieties tested, components of THC were found to be successful in
inducing cell death. Apoptotic features and/or inhibition of
proliferation were found to be the underlying mechanism.
Interestingly, two extracts consisting of equal amounts of THC but
varying levels of other cannabinoids (i.e., CBD, Cannabigerol [CBG],
THCA, etc.) had different outcomes in terms of cell death. Such
findings indicate the likelihood that the interplay of the combination
of cannabinoids may be the true determining factor of the extract's
effectiveness rather than the presence or amount of THC. Therefore,
the authors recommend whole extract cannabinoid therapy as opposed to
single-agent THC formulations that have higher anti-tumor
properties."

"The 124 extracts segregate into five major clusters comprised of
phytocannabinoids that associate with: (1) larger amounts of CBG-type;
(2) larger amounts of CBD-type.; (3) larger amounts of CBDA-type; (4)
larger amounts of Δ9-THC-type; (5) larger amounts of
Δ9-THCA-type."
Twelve cannabinoids were selected and their effect on A549 lung
cancer cell survival is shown in

"A549 cells were treated with three different Cannabis extracts:
CAN5, a Δ9-THC-rich extract; CAN9, a CBD-rich extract; and
CAN10, a CBG-rich extract. Treatment with each of these Cannabis
extracts for 24 h led to apoptosis of A549 cells in a dose-dependent
manner."
Again in A549,
"CAN5 and CAN9 extracts produced statistically significant reductions
in cell proliferation."
Both CAN2 (a CBD-type extract) and CAN5 (high THC) were among the top
scorers overall.
The colorectal adenocarcinoma HT29 cell line was the least sensitive
to all the extracts studied of all the cell lines studied, but even
so, increased apoptosis was observed with all 12 extracts in
HT29.
The values in Supplementary Table I are IC50 (not LC50 as printed -
the LC50 is an LD50 for substances in air) and IC50 is measured in
g/ml. Values above 10 are lumped together as showing the action to be
relatively useless: the lower the figure the more effective the
extract.
The half maximal inhibitory concentration (IC50) is a measure of the
potency of a substance in inhibiting a specific biological or
biochemical function. IC50 is a quantitative measure that indicates
how much of a particular inhibitory substance (e.g. drug) is needed to
inhibit, in vitro, a given biological process or biological component
by 50%.
The 144 cell line/extract combinations are CAN1 to CAN12 and
A549 (lung cancer)
NCIH460 (fast growing hypertriploid lung cancer)
PC3 (Caucasian prostate adenocarcinoma)
LNcAP (androgen-sensitive human prostate adenocarcinoma)
HT29 (colorectal adenocarcinoma)
SW480 (adenocarcinoma of the colon)
A431 (squamous carcinoma)
A375 (melanoma)
MDA231 (breast adenocarcinoma)
MCF7 (breast cancer)
U87MG (glioblastoma)
T98G (glioblastoma)
"CAN7, a Δ9-THC-rich extract, was the least discriminatory of
the twelve extracts, as it significantly reduced the survival of both
cancerous and non-cancer lung epithelial cell lines."
By my own count, pure THC beat extracts in 31 (19.9%) out of 156
pairings (Supplementary Table 1). This of course means that entourage
effects were more proapoptotic in 125 (80.1%) of the cases. At the
same time this doesn't mean THC did not contribute in the
19.9%.
The results are summarised in graphical form in Figure 3:

In their discussion the authors refer to some other reports of
synergistic effects between THC and CBD and consider that
"...beyond the major phytocannabinoids present in these extracts,
other Cannabis extract components may play a role in either increasing
phytocannabinoid potency or phytocannabinoid affinity to respective
cannabimimetic receptors, and therefore are important for the
anti-tumor effects produced by Cannabis."
They are quite definite that
"Although we observed that specific Δ9-THC-rich Cannabis
extracts were very potent in inducing cell death, their cytotoxic
effects cannot be explained solely by the amount of Δ9-THC in
the extracts. Nor can the potencies of these extracts be explained by
other individual phytocannabinoids detected in them." (Supplementary

Rios et al (2025)
"...investigated the effect of combining a terpene, Beta-Caryophyllene
(BCP), and cannabidiol (CBD) on neuropathic pain and associated
depression. We employed a chronic constriction injury (CCI)
neuropathic pain model and a series of behavioral tests to evaluate
how oral administration of this combination influences neuropathic
pain and depression-like behaviors in mice. We employed
immunohistochemistry and proteomics approaches to explore the
mechanism. Results: The analgesic effect of combining CBD and BCP is
synergistic in neuropathic pain and also shows an antidepressant
effect. Additionally, we found that this combination decreases
neuroinflammation associated with CCI and affects specific genes
involved in the inflammation."

"Does cannabidiol make cannabis safer? A randomised, double-blind,
cross-over trial of cannabis with four different CBD:THC ratios"
examined various cognitive and physiological markers:
"This study aimed to determine if increasing the CBD content of
cannabis can reduce its harmful effects. Forty-six healthy, infrequent
cannabis users participated in a double-blind, within-subject,
randomised trial of cannabis preparations varying in CBD content.
There was an initial baseline visit followed by four drug
administration visits, in which participants inhaled vaporised
cannabis containing 10 mg THC and either 0 mg (0:1
CBD:THC), 10 mg (1:1), 20 mg (2:1), or 30 mg
(3:1) CBD, in a randomised, counter-balanced order. The primary
outcome was change in delayed verbal recall on the Hopkins Verbal
Learning Task. Secondary outcomes included change in severity of
psychotic symptoms (e.g., Positive and Negative Syndrome Scale [PANSS]
positive subscale), plus further cognitive, subjective, pleasurable,
pharmacological and physiological effects. Serial plasma
concentrations of THC and CBD were measured. THC (0:1) was associated
with impaired delayed verbal recall (t(45) = 3.399, d = 0.50, p =
0.001) and induced positive psychotic symptoms on the PANSS (t(45) =
−4.709, d = 0.69, p = 2.41 105). These effects
were not significantly modulated by any dose of CBD. Furthermore,
there was no evidence of CBD modulating the effects of THC on other
cognitive, psychotic, subjective, pleasurable, and physiological
measures. There was a dose-response relationship between CBD dose and
plasma CBD concentration, with no effect on plasma THC concentrations.
At CBD:THC ratios most common in medicinal and recreational cannabis
products, we found no evidence that CBD protects against the acute
adverse effects of cannabis. This should be considered in health
policy and safety decisions about medicinal and recreational
cannabis."
and
"There were no significant differences in either peak plasma THC,
OH-THC or COOH-THC, or their respective AUCs [areas under the curve]
between the CBD:THC ratios (p > 0.008, Fig. 3A, Appendix pp612). In
contrast, there was a significant, dose-dependent increase in peak
plasma CBD, and in plasma CBD AUC, as CBD:THC ratio increased (p <
0.001, Fig. 3B, Appendix pp612). Peak plasma 7-OH-CBD was higher for
the 3:1 ratio compared to 0:1 (EMM [estimated marginal mean]
difference = 2.686, 95%CI: 1.888, 3.483, p =
1.25 10−9) and 1:1 (EMM difference = 2.206, 95%
CI: 1.551, 2.861, p = 0.002), with AUC higher for 2:1 compared to 0:1
(EMM difference = 4.676, 95% CI: 3.287, 6.064, p = 0.003) and for 3:1
compared to 0:1 EMM difference = 8.898, 95%CI: 6.256, 11.540, p =
1.71 10−9) and 1:1 (EMM difference = 6.843, 95%
CI: 4.811, 8.875, p = 3.57 10−6). Logarithmic
concentrations of THC and CBD over time, with intercept and slope
across ratios are presented in Appendix pp1314."
CBD and coughing...
"There was evidence of greater CBD:THC ratios increasing inhalation
time and coughing in a dose responsive manner (Appendix pp4650).
Greater inhalation time was correlated with lower peak and AUC
concentrations of cannabinoids at higher CBD:THC ratios."
and as for the pleasure
"All CBD:THC ratios increased scores for both chocolate and music
compared to baseline, but there were no significant differences
between the CBD:THC ratios (p > 0.008, Appendix pp4345)."

[1876]
In another study Preet et al (2007) demonstrated that two different
lung cancer cell lines as well as patient lung tumor samples express
CB1 and CB2, and that non-toxic doses of THC inhibited growth and
spread in the cell lines. When the cells are pretreated with THC, they
have less EGFR stimulated invasion as measured by various in-vitro
assays, Preet said.
"In this study we characterized the effects of THC on the EGF-induced
growth and metastasis of human non-small cell lung cancer using the
cell lines A549 and SW-1573 as in vitro models. We found that these
cells express the cannabinoid receptors CB(1) and CB(2), known targets
for THC action, and that THC inhibited EGF-induced growth, chemotaxis
and chemoinvasion. Moreover, signaling studies indicated that THC may
act by inhibiting the EGF-induced phosphorylation of ERK1/2, JNK1/2
and AKT. THC also induced the phosphorylation of focal adhesion kinase
at tyrosine 397. Additionally, in in vivo studies in severe combined
immunodeficient mice, there was significant inhibition of the
subcutaneous tumor growth and lung metastasis of A549 cells in
THC-treated animals as compared to vehicle-treated controls. Tumor
samples from THC-treated animals revealed antiproliferative and
antiangiogenic effects of THC."

[1734]
In 2010 Preet et al confirmed:
"Reduced proliferation and vascularization, along with increased
apoptosis, were observed in tumors obtained from animals treated with
JWH-133 and Win55,212-2. Upon further elucidation into the molecular
mechanism, we observed that both CB1 and CB2 agonists inhibited
phosphorylation of AKT, a key signaling molecule controlling cell
survival, migration, and apoptosis, and reduced matrix
metalloproteinase 9 expression and activity. These results suggest
that CB1 and CB2 could be used as novel therapeutic targets against
NSCLC."
https://pubmed.ncbi.nlm.nih.gov/21097714/
[3681]
According to Ramer et al (2011) "Cannabidiol inhibits lung cancer
cell invasion and metastasis via intercellular adhesion
molecule-1":
"Cannabinoids inhibit cancer cell invasion via increasing tissue
inhibitor of matrix metalloproteinases-1 (TIMP-1). This study
investigates the role of intercellular adhesion molecule-1 (ICAM-1)
within this action. In the lung cancer cell lines A549, H358, and
H460, cannabidiol (CBD; 0.001-3 μM) elicited
concentration-dependent ICAM-1 up-regulation compared to vehicle via
cannabinoid receptors, transient receptor potential vanilloid 1, and
p42/44 mitogen-activated protein kinase. Up-regulation of ICAM-1 mRNA
by CBD in A549 was 4-fold at 3 μM, with significant effects already
evident at 0.01 μM. ICAM-1 induction became significant after 2 h,
whereas significant TIMP-1 mRNA increases were observed only after 48
h. Inhibition of ICAM-1 by antibody or siRNA approaches reversed the
anti-invasive and TIMP-1-upregulating action of CBD and the likewise
ICAM-1-inducing cannabinoids Δ(9)-tetrahydrocannabinol and
R(+)-methanandamide when compared to isotype or nonsilencing siRNA
controls. ICAM-1-dependent anti-invasive cannabinoid effects were
confirmed in primary tumor cells from a lung cancer patient. In
athymic nude mice, CBD elicited a 2.6- and 3.0-fold increase of ICAM-1
and TIMP-1 protein in A549 xenografts, as compared to vehicle-treated
animals, and an antimetastatic effect that was fully reversed by a
neutralizing antibody against ICAM-1 [% metastatic lung nodules vs.
isotype control (100%): 47.7% for CBD + isotype antibody and 106.6%
for CBD + ICAM-1 antibody]. Overall, our data indicate that
cannabinoids induce ICAM-1, thereby conferring TIMP-1 induction and
subsequent decreased cancer cell invasiveness."
https://pubmed.ncbi.nlm.nih.gov/22198381/
[3680]
Meanwhile in real life:
"Conventional lung cancer treatments include surgery, chemotherapy
and radiotherapy; however, these treatments are often poorly tolerated
by patients. Cannabinoids have been studied for use as a primary
cancer treatment. Cannabinoids, which are chemically similar to our
own bodys endocannabinoids, can interact with signalling pathways to
control the fate of cells, including cancer cells. We present a
patient who declined conventional lung cancer treatment. Without the
knowledge of her clinicians, she chose to self-administer cannabidiol
(CBD) oil orally 23 times daily. Serial imaging shows that her cancer
reduced in size progressively from 41 mm to 10 mm over a period of 2.5
years. Previous studies have failed to agree on the usefulness of
cannabinoids as a cancer treatment. This case appears to demonstrate a
possible benefit of CBD oil intake that may have resulted in the
observed tumour regression. The use of cannabinoids as a potential
cancer treatment justifies further research."

Research that began in 1975 with the discovery of the antineoplastic
properties of Δ9-THC, Δ8-THC and CBN, which inhibited the
growth of Lewis lung adenocarcinoma cells. More research was needed
then and more research is still needed, now. Of course a lot of
cannabis users have delayed or prevented their death and a lot of
NECUD sufferers have not, in the intervening period.
According to "Antineoplastic activity of cannabinoids",
"Lewis lung adenocarcinoma growth was retarded by the oral
administration of delta9-tetrahydrocannabinol (delta9-THC),
delta8-tetrahydrocannabinol (delta8-THC), and cannabinol (CBN), but
not cannabidiol (CBD). Animals treated for 10 consecutive days with
delta9-THC, beginning the day after tumor implantation, demonstrated a
dose-dependent action of retarded tumor growth. Mice treated for 20
consecutive days with delta8-THC and CBN had reduced primary tumor
size. CBD showed no inhibitory effect on tumor growth at 14, 21, or 28
days. Delta9-THC, delta8-THC, and CBN increased the mean survival time
(36% at 100 mg/kg, 25% at 200 mg/kg, and 27% at 50 mg/kg,
respectively), whereas CBD did not. Delta9-THC administered orally
daily until death in doses of 50, 100, or 200 mg/kg did not increase
the life-spans of (C57BL/6 times DBA/2)F1 (BDF1) mice hosting the
L1210 murine leukemia. However, delta9-THC administered daily for 10
days significantly inhibited Friend leukemia virus-induced
splenomegaly by 71% at 200 mg/kg as compared to 90.2% for actinomycin
D. Experiments with bone marrow and isolated Lewis lung cells
incubated in vitro with delta9-THC and delta8-THC showed a
dose-dependent (10(-4)-10(-7)) inhibition (80-20%, respectively) of
tritiated thymidine and 14C-uridine uptake into these cells. CBD was
active only in high concentrations (10(-4))."
https://pubmed.ncbi.nlm.nih.gov/1159836/
[1996]
Powells et al (2005) found that THC is cytotoxic to leukemic cell
lines:
"Concentration-dependent decreases in cell viability were seen in all
cell lines cultured with THC for 2 days".
However:
"Cytotoxic effect of THC is not mediated via the CB1-R and CB2-R."
And:
"THC does not increase p53 expression."
Moreover, THC decreases phosphorylated pERK protein expression:
"Genes in the MAPK signaling cascade that showed altered expression
were DUSP6 (encoding dual specificity phosphatase 6/MAPK phosphatase 3
[MKP3]) and MAP2K2 (mitogenactivated protein kinase kinase 2/MEK2).
Interestingly, MKP3 and MAP2K2 have the same intracellular target, the
extracellular signal-regulated kinase 2 protein
(ERK2/mitogen-activated protein kinase 1). They have, however,
opposing functions: MEK2 phosphorylates, and thereby activates ERK2,
whereas MKP3 dephosphorylates ERK2, taking it to an inactive state.
Accordingly, the expression changes in response to THC observed were
an increase in MKP3 expression in all 3 samples and a decrease in
MAP2K2 expression (Table 2). Both changes are consistent with
decreased MAPK signaling."

Now the idea in practice is, you ignore alcohol causing cancer, food
causing cancer, heavy metals causing cancer, plastics causing cancer
and everything else causing cancer. After you have ignored those
things for a while,...Oh! You have cancer. But the mechanisms involved
in the progress of cancer did not suddenly appear with the diagnosis
of the disease. They were there all the time, but in balance and under
control.
Following the 1975 Munson et al paper on Lewis lung adenocarcinoma,
according to Abrams:
"For unclear reasons, that line of research was not pursued further
at the National Institutes of Health in the United States, but was
subsequently picked up by investigators in Spain and Italy, who have
made enormous contributions to the field.
"If cannabinoids are postulated to have a potential anticancer effect
working through the cb1 receptor, it would follow that the brainwhere
the cb1 receptor is the most densely populated seven-transmembrane
domain G protein coupled receptor would be a good place to start the
investigation. And, in fact, numerous studies in vitro and in animal
models have suggested that cannabinoids can inhibit gliomas. Other
tumour cell lines are also inhibited by cannabinoids in vitro, and
cannabinoid administration to nude mice curbs the growth of various
tumour xenografts representing multiple solid and hematologic
malignancies, including adenocarcinomas of the lung, breast, colon,
and pancreas, and also myeloma, lymphoma, and melanoma."

Abrams, who can be found in the Hematology-Oncology department at San
Francisco General Hospital; also at Integrative Oncology, UCSF Osher
Center for Integrative Medicine; and also at the University of
CaliforniaSan Francisco, San Francisco, CA, U.S.A., writing March 23
in Current Oncology, wrote:
"Much attention has been paid to the unearthing of the 2500-year-old
mummy known as the 'Siberian Ice Maiden.' Discovered in 1993, her
subterranean burial chamber included a pouch of cannabis among other
archeologic findings. Magnetic resonance imaging revealed that the
princess had a primary tumour in the right breast, with axial
adenopathy and metastatic disease. It is hypothesized that the
cannabis was used to manage her pain and perhaps other symptoms, or
even possibly as a treatment for her malignant disease.
"Widely used as medicine during the ensuing millennia, cannabis
disappeared from the pharmaceutical armamentarium in the 1940s as its
prohibition took hold. Today, we are in the midst of what appears to
be something of a medicinal cannabis renaissance, with patients across
the globe gaining increased access to this potent botanical medicine.
In a 2014 WebMD poll, 82% of oncologists indicated their belief that
patients should have access to cannabis, ranking highest among medical
subspecialists in their support. Regrettably, most oncologists trained
during the era of cannabis prohibition and have no knowledge of how to
use the plant as medicine. In these days of targeted therapies and
nanotechnology, the modern oncologist might feel somewhat ill at ease
recommending a herbal intervention, notwithstanding the number of
potent cytotoxic chemotherapeutic agents derived from plants."

and in a suggestion for more research that might be needed...
"Even more exciting would be a study demonstrating the potential for
cannabis to actually lower the risk for neuropathy or to prevent it
from developing in the first place, as the animal models
suggest."
Meanwhile we are reminded
"The cb receptors are not present to react with the phytocannabinoids
from cannabis alone. They exist because, on demand, humans produce
endogenous cannabinoidsendocannabinoidsthat react with the receptors,
effecting changes in intracellular signalling. It has been suggested
that the entire function of the system of cannabinoid receptors and
endocannabinoids might be to assist in modulation of the response to
pain. With that in mind, it is not surprising that an increasing body
of knowledge is being developed about the effects on pain of
cannabinoid medicines." [1997]
By 2022 the same author was reporting that
"THC and CBD may both impact the metabolism of other pharmaceuticals
and botanicals by way of cytochrome p450 interactions. To date, very
few pharmacokinetic interaction studies have been investigated to
evaluate the effects of cannabis or isolated cannabinoids on blood
levels of conventional cancer therapies."
and
"No studies of cannabis to promote weight gain in cancer patients
have been reported likely due to the barriers to conducting research
with the botanical. Cannabis, however, with both antiemetic and
orexigenic effects, may be a useful therapeutic for cancer patients
and should be further explored in future clinical
investigations."

Tai, Wong and Wen (2015), recalling that
"Innate immunity is the first line of defense of the body in response
to exogenous insults such as bacterial, viral and fungal infections
and innate immunity acts through highly conserved pattern-recognition
receptors, such as Toll-like receptors (TLR), to coordinate the innate
inflammatory response to both endogenous and exogenous stimuli. After
engaging with their ligands, the downstream inflammatory responses of
most TLRs are mediated through the [Myeloid differentiation primary
response 88] MyD88-dependent pathway, except TLR3, which is
[TIR-domain-containing adapter-inducing interferon-β] TRIF
dependent."
and they tell us a 2014
"...study by Alkanani and colleagues also showed that induction of
diabetes in the RIP-B7.1 C57BL/6 mouse model was critically dependent
on TLR3 and MyD88 pathways and an altered intestinal microbiome was
responsible for the diabetes modulation. Experimental data from BB
rats performed by Roesch and colleagues also showed the altered gut
microbiota were linked to the onset of diabetes in BB-DP
(diabetes-prone) compared to BB-DR (diabetes-resistant) rats.
Moreover, Hara et al showed that antibiotic treatment could prevent
Kilham rat virus-induced insulitis and T1D in the LEW1.WR1 rat model,
suggesting that microbiota might also be involved in virus-induced
diabetes. Transfer of gut microbiota from diabetes-protected
MyD88-deficient [non-obese diabetic] NOD mice at an early age could
stably alter the composition of the gut microbiota of recipient NOD
mice, reduce insulitis and significantly delay the onset of diabetes.
Taken together, these data indicate altered gut microbiota are
strongly associated with T1D and modulation of the gut microbiota by
transfer of so-called 'protective gut flora' could delay and/or
prevent diabetes development. However, how gut microbiota are altered
and what mechanisms are involved in the immune regulation by the
commensal bacteria in diabetes development need to be further
investigated."

In "CNS Demyelination Syndromes Following COVID-19 Vaccination: A
Case Series" by Yasser et al (2024):
"The study was carried out on 18 patients who presented with
different neurological disorders after the first or second dose of the
COVID-19 vaccine. There were eight men (44.44%) and ten women (55.56%)
with a mean age of 34.78 7.13 years, ranging from 23 to 44 years. The
mean duration between the onset of symptoms and the date of the last
dose of the COVID-19 vaccine was 7.67 3.83 days, ranging from 214
days. Regarding the type of vaccine, 12 patients (66.67%) received the
Pfizer vaccine, and the remaining six (33.33%) received the
AstraZeneca vaccine. Eight patients (44.44%) developed neurological
manifestations after the first dose of the vaccine, and the remaining
ten (55.56%) developed them after the second dose [Table 1].
"Four patients (22.22%) presented with optic neuritis, three (16.67%)
with hemiparesis, three (16.67%) with paraparesis, three (16.67%) with
seizures (GTC and myoclonic), two (11.11%) with ataxia, one (5.56%)
with hemihypesthesia, one (5.56%) with headache, and one (5.56%) with
tinnitus [Table 2]. Sixteen patients (88.89%) had brain MRI findings
suggestive of a demyelinating disorder [Figures 1 and 2], and two
(11.11%) had a normal brain MRI but with the spine MRI showing a
picture of transverse myelitis [Figure 3]. In the results of the
oligoclonal band in CSF and serum, ten patients (55.56%) had a
positive oligoclonal band in the CSF only, and the remaining eight
(44.44%) had negative results. VEP was performed for ten patients. The
results showed that four (22.22%) had prolonged P 100 latency, and the
remaining six had normal P 100 latency. AQP-4 was performed for three
patients and was negative [Tables 3 and 4]."
As to the potential mechanisms of this they say:
"Although the precise mechanism of demyelination following COVID-19
vaccinations is still not fully known, a combination of
vaccine-related variables and patient susceptibility plays a
significant role. Some individuals may experience an unintended immune
reaction as a result of the resemblance between the proteins of the
viruses used for vaccination and self-antigens (such as myelin).
Another factor is the use of immunologic adjuvants, which are
substances that increase immune responses to certain antigens and can
mimic evolutionarily conserved chemicals that activate both the innate
and adaptive immune systems. TLR7 and TLR8 activation also results in
the production of type I interferon, potent T and B cell responses,
and the activation of bystander autoreactive cells. This bystander
activation and cytokine secretion by macrophages might lead to local
inflammation and the recruitment of more T-helper cells."

Anything which could ameliorate these odds ought not to be banned.
In 2000, five months after the enactment of the ZPPPD, Derocq and
colleagues investigated the "enigma" of the CB2 receptor, becoming the
first to discover a role in immune cell differentiation and
chemotaxis, as:
"...activation of the CB2 receptors induced an up-regulation of nine
genes involved in cytokine synthesis, regulation of transcription, and
cell differentiation. A majority of them are under the control of the
transcription factor NF-kB, whose nuclear translocation was
demonstrated. Many features of the transcriptional events, reported
here for the first time, appeared to be related to an activation of a
cell differentiation program, suggesting that CB2 receptors could play
a role in the initialization of cell maturation. Moreover, we showed
that CB2-activated wild-type HL-60 cells developed properties usually
found in host defense effector cells such as an enhanced release of
chemotactic cytokines and an increased motility, characteristic of
more mature cells of the granulocytic-monocytic lineage."
https://www.jbc.org/article/S0021-9258(19)80340-X/pdf
[3531]
In 2005 the CB2 receptor was shown to be essential for macrophage
chemotaxis.

[3530]
Low dose THC was found to reduce the progression of atherosclerosis
in mice. According to Steffens et al (2005):
"Lymphoid cells isolated from THC-treated mice showed diminished
proliferation capacity and decreased interferon-γ secretion.
Macrophage chemotaxis, which is a crucial step for the development of
atherosclerosis, was also inhibited in vitro by THC. All these effects
were completely blocked by a specific CB2 receptor antagonist. Our
data demonstrate that oral treatment with a low dose of THC inhibits
atherosclerosis progression in the apolipoprotein E knockout mouse
model, through pleiotropic immunomodulatory effects on lymphoid and
myeloid cells."

This could turn out to be useful and adds to the risks of NECUD as
SARS-CoV-2, the virus that causes COVID-19, can directly infect the
arteries of the heart and cause the fatty plaque inside arteries to
become highly inflamed, increasing the risk of heart attack and
stroke, according to "SARS-CoV-2 infection triggers pro-atherogenic
inflammatory responses in human coronary vessels" by Eberhardt et al
(2023):
"Here we report that SARS-CoV-2 viral RNA is detectable and
replicates in coronary lesions taken at autopsy from severe COVID-19
cases. SARS-CoV-2 targeted plaque macrophages and exhibited a stronger
tropism for arterial lesions than adjacent perivascular fat,
correlating with macrophage infiltration levels. SARS-CoV-2 entry was
increased in cholesterol-loaded primary macrophages and dependent, in
part, on neuropilin-1. SARS-CoV-2 induced a robust inflammatory
response in cultured macrophages and human atherosclerotic vascular
explants with secretion of cytokines known to trigger cardiovascular
events. Our data establish that SARS-CoV-2 infects coronary vessels,
inducing plaque inflammation that could trigger acute cardiovascular
complications and increase the long-term cardiovascular risk."
Cholesterol-laden foam cells were the most susceptible to infection
and unable to readily clear the virus. This suggested that foam cells
might act as a reservoir of SARS-CoV-2 in the atherosclerotic
plaque:
"The significantly higher accumulation of nucleoprotein (NP) in foam
cells compared to macrophages infected with SARS-CoV-2 USA WA1/2020
isolate (Fig. 2b and Extended Data Fig. 3b) confirmed a higher
susceptibility of foam cells to the virus."

In a 2015 study macrophage chemotaxis was found to be activated by
CB2R agonists but independently of them. According to Taylor et
al:
"Activation of CB2 has been demonstrated to induce directed immune
cell migration. However, the ability of CB2 to act as a
chemoattractant receptor in macrophages remains largely unexplored.
Using a real-time chemotaxis assay and a panel of chemically diverse
and widely used CB2 agonists, we set out to examine whether CB2
modulates primary murine macrophage chemotaxis. We report that of 12
agonists tested, only JWH133, HU308, L-759,656 and L-759,633 acted as
macrophage chemoattractants. Surprisingly, neither pharmacological
inhibition nor genetic ablation of CB2 had any effect on CB2
agonist-induced macrophage chemotaxis. As chemotaxis was pertussis
toxin sensitive in both WT and CB2-/- macrophages, we concluded that a
non-CB1/CB2, Gi/o-coupled GPCR must be responsible for CB2
agonist-induced macrophage migration. The obvious candidate receptors
GPR18 and GPR55 could not mediate JWH133 or HU308-induced cytoskeletal
rearrangement or JWH133-induced β-arrestin recruitment in cells
transfected with either receptor, demonstrating that neither are the
unidentified GPCR. Taken together our results conclusively demonstrate
that CB2 is not a chemoattractant receptor for murine macrophages.
Furthermore we show for the first time that JWH133, HU308, L-759,656
and L-759,633 have off-target effects of functional consequence in
primary cells and we believe that our findings have wide ranging
implications for the entire cannabinoid field."
They say:
"Real-time analysis of changes in cell morphology demonstrated that
L-759,656 induced concentration dependent signalling (Fig. 3D),
whereas the chemotaxis negative compounds CP55,950, AM1241 (Fig. 3D),
GP1a and WIN55212-2 (Fig. 3E) did not induce signalling at any
concentration tested. In summary, using both Boyden chamber and
real-time chemotaxis assays we have shown that only a subset of CB2
agonists act as primary murine macrophage chemoattractants and only
chemotaxis positive compounds were capable of inducing changes in cell
morphology as measured by changes in electrical impedance.

Writing in 2016, F Rohan Walker and Raz Yirmani describe the shift in
thinking about microglia:
"The remarkable number of discoveries over the last decade concerning
microglial involvement in the most fundamental CNS processes has
caught many by surprise. To a certain extent, this surprise has been
driven by long established assumptions concerning the primary role of
microglia as immune type cells within the brain. Indeed, the
literature prior to 2005 is filled with descriptions of microglia as
the macrophages of the brain, with detailed investigation of how these
cells function as the first-responders to tissue injury or insult
(Kreutzberg, 1996). However, 2005 represented a departure from this
classical outlook, with the first observation of these cells in real
time being reported (Davalos et al., 2005, Nimmerjahn et al., 2005).
These multiphoton imaging studies revealed that microglia are
incredibly active, rapidly extending and retracting their processes,
apparently in an effort to scan their microenvironment. The question
on all microgliologists minds at the time was, scanning for what? In
rapid succession, it became apparent that rather than patrolling for
threats (or only for threats), microglia were in fact making
continuous contact with pre- and post-synaptic terminals to monitor
synaptic activity (Kettenmann et al., 2013, Tremblay et al., 2010,
Wake et al., 2009). Furthermore, during development, such
microglial-neuronal interactions were found to be crucial for synaptic
maturation and pruning, which underlie the activity-dependent tuning
and refinement of neuronal circuits and the brains global connectivity
pattern (Paolicelli et al., 2011, Schafer et al., 2012, Zhan et al.,
2014). These discoveries subsequently proved to be immensely
important, as there was now a credible chain of evidence through which
immunological activity could directly influence both neuronal
architecture and function."

[3533]
According to "Neuroscience" 2nd edition (2001):
"By acting as an electrical insulator, myelin greatly speeds up
action potential conduction (Figure 3.14). For example, whereas
unmyelinated axon conduction velocities range from about 0.5 to 10
m/s, myelinated axons can conduct at velocities up to 150 m/s. The
major reason underlying this marked increase in speed is that the
time-consuming process of action potential generation occurs only at
specific points along the axon, called nodes of Ranvier, where there
is a gap in the myelin wrapping (see Figure 1.4F). If the entire
surface of an axon were insulated, there would be no place for current
to flow out of the axon and action potentials could not be generated.
As it happens, an action potential generated at one node of Ranvier
elicits current that flows passively within the myelinated segment
until the next node is reached. This local current flow then generates
an action potential in the neighboring segment, and the cycle is
repeated along the length of the axon. Because current flows across
the neuronal membrane only at the nodes (see Figure 3.13), this type
of propagation is called saltatory, meaning that the action potential
jumps from node to node. Not surprisingly, loss of myelin, as occurs
in diseases such as multiple sclerosis, causes a variety of serious
neurological problems."
https://www.ncbi.nlm.nih.gov/books/NBK10921/
[2273]
A 2019 view of multiple sclerosis:
"The pathogenesis of this disease is characterized by
neuroinflammation leading to demyelination and consequently paralysis.
Although the complete etiology and the pathogenesis of MS remains
unclear, there is evidence that increased migration of myelin-reactive
CD4 + Th1 and Th17 cells across the blood-brain barrier (BBB) causing
inflammation in the CNS which leads to axonal demyelination of
neurons, axonal injury, oligodendrocyte loss, neuronal damage, and
glial plaques (Wu and Chen, 2016)." [1285]
In 2022 Biomedicine published "Neurological Benefits, Clinical
Challenges, and Neuropathologic Promise of Medical Marijuana: A
Systematic Review of Cannabinoid Effects in Multiple Sclerosis and
Experimental Models of Demyelination" by Longoria et al.
"Despite current therapeutic strategies for immunomodulation and
relief of symptoms in multiple sclerosis (MS), remyelination falls
short due to dynamic neuropathologic deterioration and relapses,
leading to accrual of disability and associated patient
dissatisfaction. The potential of cannabinoids includes add-on
immunosuppressive, analgesic, neuroprotective, and remyelinative
effects."
and
"MS exhibits heterogeneity with respect to clinical, genetic,
radiographic, and pathologic features. Triggers for MS development and
relapses involve interactions between genetic, lifestyle, and
environmental factors. Genome-wide association studies (GWAS) have
identified over 230 genetic risk loci for MS, revealing a ~5-fold
increase in the risk of MS when the presence of the class II variant
HLA-DRB1*15:01 is combined with an absence of the class I variant
HLA-A*02. Other risk factors for MS include smoking, alcohol
consumption, obesity, low dietary intake of vitamin D, lower sun
exposure, latitude farther away from equator, and certain chronic
viral infections. Longitudinal analysis using data from US military
recruits over a period of 20 years has revealed that EpsteinBarr virus
(EBV) increased the risk of subsequent MS by 32-fold. MS patients have
significantly higher serum anti-EBV nuclear antigen-1 (EBNA-1) titers
as compared to healthy controls, and the higher EBV responses
correlate with more extensive lesion and gray matter tissue
destruction as measured by magnetization transfer imaging in RRMS
patients. Molecular mimicry may explain the association between EBV
titers and more severe neuropathology since ~2025% of MS patients have
anti-EBNA1 antibodies that cross-react with the CNS protein glial cell
adhesion molecule (GlialCAM].
"In humanized non-obese diabetic-severe combined immunodeficiency
(NOD-scid) IL2 receptor γ-chain-deficient (huNSG) mice, EBV
infection was found to synergize with HLA-DR15 by priming
cross-reactive CD4+ T-cell clones which control the viral infection
less efficiently. It is hypothesized that EBV might activate ancestral
human endogenous retroviruses (HERVs) in the human genome. Antibodies
to other viruses have been associated with increased MS conversion and
relapse including human herpes virus 6 (HHV-6). It is believed that
the induction of demyelination in the brain and spinal cord in MS may
be initiated by excess innate and myelin-specific autoimmune
activation mechanisms that are sensitive to chronic viral infections
and gut microbiome status and perpetuated by the loss of
oligodendrocytes and their progenitors through either
perforin-mediated lysis or apoptotic cell death."
and
"Early studies also demonstrated that cannabinoids could ameliorate
clinical progression, downregulate proinflammatory T cells, and
promote remyelination in TMEV-IDD."
and
"Clinical studies suggest that combinations of the cannabinoids
derived from the Cannabis sativa plant, cannabidiol (CBD) and
Δ9-tetrahydrocannabinol (Δ9-THC), are comparably as
effective for short-term symptomatic relief as conventional
pharmacotherapeutic agents while causing less side effects. An
oromucosal spray formulation, Sativex (nabiximols), which contains
Δ9-THC and CBD in a nearly 1:1 ratio, was licensed in the United
Kingdom in 2010 as a prescription-only medicine for the treatment of
spasticity in multiple sclerosis."
14 animal and 14 human studies were reviewed. In the human
tests:
"Spasticity outcomes were reported in nine studies: three randomized,
double-blind, placebo-controlled clinical trials, and six
cohort/observational studies. The quality of evidence [Cochrane] GRADE
[Grading of Recommendation Assessment, Development and Evaluation] was
moderate in six and low in three of the studies (Table 7 and Table 8).
The total number of subjects for spasticity studies was 1582. The mean
maximal change in NRS [numerical rating scale] spasticity scores was
2.8 (range 0.04 to 7.4) lower than baseline. Assessments were repeated
more than once within a period of 4 months, and two of the studies
extended up to 12 months. In the three clinical trials, the mean
difference in NRS spasticity scores was 0.62 (range 0.5 to 0.83)
points lower in the treatment groups as compared to controls, as a
placebo effect was noted in two of the trials."
"Cannabis-based medicine has long been known to be useful in pain
management including central pain in multiple sclerosis and
post-operative pain. Promising benefits of cannabis use and medical
marijuana have also been observed for relief of neurologic symptoms in
patients with movement disorders, including Parkinson disease and
Huntington disease. Furthermore, oral CBD has been used for the
treatment of drug-resistant seizures in children with tuberous
sclerosis (TSC), and Epidiolex (pure CBD) has been approved for the
treatment of intractable epilepsy in patients with developmental
epileptic encephalopathies including Dravet syndrome and LennoxGastaut
syndrome (LGS). Multiple mechanisms are implicated in the ability of
CBD to modulate seizures that include antagonism of CB1, CB2, GPR18,
GPR55, and voltage-gated sodium channel (VGSC) receptors; agonism of
GABAA receptors; activation and desensitization of TRPV1/2 receptors;
and allosteric modulation of opioid receptor types μ [mu] and
δ [delta], leading to inhibition of glutaminergic
N-methyl-D-aspartate (NMDA) receptors."
...
"In addition to neuroprotective effects, cannabinoid treatment in
vitro and in vivo has antiseizure, antiemetic, anti-inflammatory, and
antitumor effects which include antiproliferative, proapoptotic,
autophagic, antiadhesion, antimigration, and antiangiogenic mechanisms
affecting cancer cells, cell lines, human tumor xenografts, and animal
cancer models."
...
"Recent studies have provided evidence implicating lysophosphatidic
acid (LPA) signaling through its G protein-coupled receptor, LPA1, as
a mechanism of macrophage activation that correlates with the onset of
relapses and greater disease severity in both EAE and MS. Interactions
between the endocannabinoid system and the LPA system in the mouse
brain have been identified in studies demonstrating upregulation of
LP1 receptor activity in CB1 knockout mice. Cannabinoids have also
been shown to promote a reparative activation state of microglia and
macrophages, diminishing the reactivity and the number of microglia in
Theilers virus-induced demyelination disease. RNA sequencing analysis
has revealed that oral CBD treatment of EAE mice can reduce the
expression of CXCL9, CXCL10, and IL-1β, leading to decreased
macrophage infiltration into the CNS, and also induce myeloid-derived
suppressor cells (MDSCs)."
...
"CB2-mediated facilitation of oligodendrocyte survival involved
decreases in the phosphorylation of the protein kinase R (PKR)-like
endoplasmic reticulum (ER) kinase (PERK), eIF2α, ATF4, and
GADD34 (Growth Arrest and DNA Damage-inducible protein) signaling
pathway in microglia."
...
"Treatment with Δ9-THC also promoted axonal remyelination in
organotypic cerebellar cultures. CB1 receptors regulate the mTORC1
signaling pathway during oligodendrocyte development, and the
remyelination effects could be abrogated by both mTORC1 blockade and
CB1 receptor-selective antagonism."

"Analysis of patient-reported outcome measures in 312 patients from

In 2022, examining the effects of cannabinoids on toll-like
receptors, Fitzpatrick et al
"...employed the use of poly(I:C) and lipopolysaccharide (LPS) to
induce viral TLR3 and bacterial TLR4 signalling, and [peripheral blood
mononuclear cells] PBMCs were pre-exposed to plant-derived highly
purified THC (10 μM), CBD (10 μM), or a combination of both
phytocannabinoids (1:1 ratio, 10:10 μM), prior to LPS/poly(I:C)
exposure. TLR3 stimulation promoted the protein expression of the
chemokine CXCL10 and the type I IFN-β in PBMCs from both cohorts.
THC and CBD (delivered in 1:1 combination at 10 μM) attenuated
TLR3-induced CXCL10 and IFN-β protein expression in PBMCs from
[people with multiple sclerosis] pwMS and HCs, and this effect was not
seen consistently when THC and CBD were delivered alone."
As their paper "Botanically-Derived ∆ 9 -Tetrahydrocannabinol and
Cannabidiol, and Their 1:1 Combination, Modulate Toll-like Receptor 3
and 4 Signalling in Immune Cells from People with Multiple Sclerosis"
explains:
"A body of preclinical data indicate that THC and CBD have
anti-inflammatory and antioxidant propensity, and TLRs are cannabinoid
targets. Indeed, recent findings from our laboratory indicate that
both THC and CBD target inflammatory signalling governed by TLRs in
human macrophages, specifically TLR3 and TLR4. Such data, particularly
with regard to THC, are important in the context of evidence linking
the endocannabinoid system (ECS) with the pathogenesis of MS. Indeed,
the expression of the endocannabinoid anandamide (AEA) is enhanced in
CSF, lymphocytes, and plasma of pwMS, while knock-out of the
cannabinoid receptors CB1 and CB2, and administration of the AEA
metabolising enzyme fatty acid amide hydrolase (FAAH), alters the
clinical progression of [experimental autoimmune encephalomyelitis]
EAE in mice."

"Δ9-Tetrahydrocannabinol and cannabidiol selectively suppress
toll-like receptor (TLR) 7 and TLR8-mediated interleukin-1β
production by human CD16+ monocytes by inhibiting its
post-translational maturation" say Sermet et al (2025):
"We hypothesized that THC and CBD suppress toll-like receptor (TLR) 7
or TLR8-induced inflammatory profiles by CD16+ and CD16−
monocytes, specifically interleukin (IL) 1β maturation.
Cannabinoid receptor 2 selective agonist, JWH-015, was used to deduce
whether cannabinoid receptor 2 signaling alone can mimic
immune-modulating properties of THC. Primary human CD16+ and
CD16− monocytes were pretreated with THC, CBD, or JWH-015 and
then activated through TLR7 or TLR8. Activated monocytes mainly
produced IL-1β, tumor necrosis factor-⍺, and IL-6. We show that
THC and CBD, but not JWH-015, exert anti-inflammatory effects on
primary human monocyte apoptosis-associated speck-like
proteinincorporating inflammasome formation and subsequent caspase-1
activity, contributing to suppressed IL-1β production. In
addition, mRNA expression of IL1B, CASP1, NLRP3, and PYCARD were
unaffected by THC. Minimal THC effects were observed on TLR8-mediated

So we need to know a bit more about oligodendrocytes. These were
discovered by the application of a novel silver carbonate staining
method in 1918 by Pio Del Ro Hortega.
"After developing modifications of Achcarros ammoniacal silver method
(Del Ro Hortega, 1916), Del Ro Hortega challenged the accuracy of Ramn
y Cajals concept about the third element of CNS which grouped non
neuronal (first element) and non-astrocytic (second element) cells
(Ramn y Cajal, 1913b, 1916; Garca-Marn et al., 2007). Later, he
described his silver carbonate staining technique which was the
methodological key to identify two distinct elements: the microglia,
the true third element, and what he called initially interfascicular
cells and later oligodendroglia (Del Ro Hortega, 1918, 1920,
1921)."
And, writing in 2015, Achucarro Basque Center for Neuroscience
authors say that:
"He established their ectodermal origin and suggested that they built
the myelin sheath of CNS axons, just as Schwann cells did in the
periphery. Notably, he also suggested the trophic role of OLGs for
neuronal functionality, an idea that has been substantiated in the
last few years....Yet, the difficulty of metal impregnation methods
and their variability in results, delayed for some decades the
confirmation of his great insights into oligodendrocyte biology until
the development of electron microscopy and
immunohistochemistry."

From whence does damage to oligodendrocytes originate? All around us,
in everyday household products, in my home and yours. According to
Cohn et al at the Department of Genetics and Genome Sciences, Case
Western Reserve University School of Medicine, Cleveland,
who...
"...revealed environmental chemicals in two classes that disrupt
oligodendrocyte development through distinct mechanisms. Quaternary
compounds, ubiquitous in disinfecting agents, hair conditioners, and
fabric softeners, were potently and selectively cytotoxic to
developing oligodendrocytes through activation of the integrated
stress response. Organophosphate flame retardants, commonly found in
household items such as furniture and electronics, were non cytotoxic
but prematurely arrested oligodendrocyte maturation. Chemicals from
each class impaired human oligodendrocyte development in a 3D organoid
model of prenatal cortical development. In analysis of epidemiological
data from the CDCs National Health and Nutrition Examination Survey,
adverse neurodevelopmental outcomes were associated with childhood
exposure to the top organophosphate flame retardant identified by our
oligodendrocyte toxicity platform."

A Madrid-Boston collaboration states that it is not just a matter of
maintenance for people already diagnosed with MS, but also of
remyelination - i.e. repair of myelin - and prevention of
demyelination in the first place that cannabinoids impart to the user
population, and they say:
"Neuroprotective therapies, and those targeting oligodendrocyte
progenitors and other CNS cells, such as astrocytes and microglia, are
likely to promote recovery and prevent long-term neurodegeneration.
Indeed, the neuroprotective effects of CBs have been confirmed in
different models of injury and CNS disease, like Alzheimers Disease
(Martn-Moreno et al., 2012; Schubert et al., 2019), stroke (Zarruk et
al., 2012; Kolb et al., 2019), ischemic injury (Fernndez-Lpez et al.,
2007), Parkinsons Disease (Garca et al., 2011) and ALS (Rodrguez-Cueto
et al., 2018). In the TMEV-IDD model of progressive MS, the
administration of synthetic CBs (Arvalo-Martn et al., 2003) or pCBs
(Mecha et al., 2013; Feli et al., 2015) has been associated with an
improvement in neurological defects, also observed by inhibiting
selective AEA uptake (Ortega-Gutirrez et al., 2005) or the enzymatic
hydrolysis of 2-AG (Feli et al., 2017). In this latter study, both
remyelination and axon preservation was showed, while chondroitin
sulfate proteoglycans diminished through the involvement of CB1R and
CB2R. In addition, 2-AG administration or inhibition of its hydrolysis
favors oligodendrocyte precursor cell (OPC) differentiation (Gomez et
al., 2015) and, by diminishing the excitotoxicity of oligodendrocytes,
demyelination is prevented in the EAE (Bernal-Chico et al., 2015) and
the cuprizone model (Manterola et al., 2018)."

Next, to a recent but flawed review, "Drugs and Bugs: The Gut-Brain
Axis and Substance Use Disorders":
"CBD is immune suppressive in both in vitro and in vivo models

explored in individuals with cannabis use disorder, IL-1β, IL-6,
IL-8 and TNF⍺ were increased in cannabis users compared to

By 2016 Omar Abdel-Salam at the Department of Toxicology and
Narcotics in the Medical Division of the National Research Centre, in
Cairo, Egypt, was convinced that "The effects of Cannabis are,
however, the sum of its constituents."
This is an article which begins with the sentence:
"Cannabis is the most commonly abused illicit substance
worldwide."
But he could have said, "Cannabis is the most commonly prohibited
substance used worldwide."
It's clear from the context of the following paragraph that what
Abdel-Salam means to say is:
"The effects of Cannabis are, however, [more than] the sum of its
constituents. There are more than 70 different cannabinoids and these
may have effects that are synergistic with or antagonistic to
Δ9-THC effects. Other important constituents are terpenoids and
the flavonoids flavocannabiside. One terpenoid that is
beta-caryophyllene has been shown to inhibit the development of
gastric lesions evoked by ethanol or 0.6 N HCl when given orally to
rats."

A year later mrstinkysgreengarden.com discussing the benefits of
linalool:
"Modern research has confirmed the practices of ancient
civilizations, revealing strong medical efficacy for many severe
conditions.
"Linalool has been shown to be a major anti-inflammatory, meaning it
helps those with cancer and arthritis. Research has also proven the
value of this terpene for treating anxiety and insomnia due to its
sedative properties.
"Linalool is actually one of the minor terpenes available in certain
strains of cannabis. It is found in smaller quantities than major
terpenes like myrcene (the most common), pinene, and limonene. It
emits a floral, sometimes spicy aroma. Hundreds of species of plants
produce linalool, including a variety of mints and herbs."

[975]
"It comes in two main forms: an R isomer (R-linalool, also known as
licareol) and an S isomer (S-linalool, or coriandrol).
"Linalool smells floral and musky with a faint hint of spice much like
lavender. However it is far more ubiquitous in nature, with R-Linalool
found in over 200 different plants such as flowering plants in the
Lamiaceae family (lavender, lemon balm, bergamot, rosemary, sage) as
well as the present in the Lauraceae and Apiaceae plant families."

One starting point for a consideration of CCx synergistic or
antagonistic effects is sleep.
In your mission to construct an artificial optimally balanced mix of
CCx so you can patent a drug affecting pathway Y for condition Z, you
might start by varying the simplest variables, THC and CBD, then add
linalool, or any one or more of these major or minor cannabinoids or
terpenes, or not.
As you can see, there will be quite a lot of sleep experiments to do,
to invent cannabis.
More sleep might not be the only solution. If you are simply unable
to get enough "β-Caryophyllene (BCP) prevented cognitive deficits
induced by acute sleep deprivation" according to Cao et al (2026):
"Here we administered β-caryophyllene (BCP), the highly selective
CB2R agonist, and observed whether cognitive impairment following
acute sleep deprivation (ASD) was prevented. Our results demonstrated
that administration of BCP for 3 days before ASD markedly prevented
both long-term spatial learning and memory, along with short-term
episodic recall in mice exposed to ASD, but the four experimental
groups of mice exhibited comparable hippocampal CB2R expression
without marked differences. In addition, BCP effectively reversed the
disruption of long-term potentiation (LTP) in the hippocampal CA1 area
induced by ASD, but failed to reestablish long-term depression (LTD)
or paired pulse ratio (PPR). Furthermore, BCP prevented synaptic
ultrastructural alterations and promoted the recovery of both
dendritic spine density and morphological complexity within the CA1
subfield of the hippocampus. Overall, these results indicate that BCP
prevented cognitive impairment after ASD by preventing damage to
synaptic function and structural plasticity, preventing alterations of
pyramidal cell dendritic complexity and density of dendritic spines
within CA1 subregion of hippocampi of mice."

Advances in the relatively recent tools to study sleep mean that, as
with the microbiome and the inflammasome, most of the findings
postdate the applicable treaties and legislation.
Matthew P Walker is a British author, scientist and professor of
neuroscience and psychology at the University of California, Berkeley.
He is a public intellectual focused on the subject of sleep. A list of
studies to which has contributed can be located at
https://scholar.google.com/citations?user=11L5sOQAAAAJ&hl=en
[3090]
Matt Walker has a 19 minute talk about the deleterious effects of
poor sleep. (Warning: contains testicles).
"Sleep is your life-support system and Mother Nature's best effort
yet at immortality, says sleep scientist Matt Walker. In this deep
dive into the science of slumber, Walker shares the wonderfully good
things that happen when you get sleep -- and the alarmingly bad things
that happen when you don't, for both your brain and body. Learn more
about sleep's impact on your learning, memory, immune system and even
your genetic code..."
In case you are too tired to watch it all, Walker emphasizes that
sleep is not a luxury but a biolgical necessity, and declares
"the shorter your sleep, the shorter your life"
The genetic profile of healthy adults limited to six hours' sleep for
one week was compared to their baseline profile when they received a
"normal" eight hours.
"First, a sizeable and significant 711 genes were distorted in their
activity, caused by a lack of sleep. The second result was that about
half of those genes were actually increased in their activity. The
other half were decreased.
"Now those genes that were switched off by a lack of sleep were genes
associated with your immune system....in contrast, those genes that
were actually upregulated or increased by way of a lack of sleep were
genes associated with the promotion of tumours, genes associated with
long-term chronic inflammation of the body, and genes associated with
stress, and, as a consequence, cardiovascular disease. There is simply
no aspect of your wellness that can retreat at the sign of sleep
deprivation."
and
"And let me just tell you about one area that we've moved this work
out into, clinically, which is the context of aging and dementia.
Because it's of course no secret that, as we get older, our learning
and memory abilities begin to fade and decline. But what we've also
discovered is that a physiological signature of aging is that your
sleep gets worse, especially that deep quality of sleep that I was
just discussing. And only last year, we finally published evidence
that these two things, they're not simply co-occurring, they are
significantly interrelated. And it suggests that the disruption of
deep sleep is an underappreciated factor that is contributing to
cognitive decline or memory decline in aging, and most recently we've
discovered, in Alzheimer's disease as well."

In a poll of 229 "mental health experts" the statement "sleep

NECUD may affect quality of sleep. According to Mller-Levet et al
(2013):
"Insufficient sleep and circadian rhythm disruption are associated
with negative health outcomes, including obesity, cardiovascular
disease, and cognitive impairment, but the mechanisms involved remain
largely unexplored. Twenty-six participants were exposed to 1 wk of
insufficient sleep (sleep-restriction condition 5.70 h, SEM = 0.03
sleep per 24 h) and 1 wk of sufficient sleep (control condition 8.50 h
sleep, SEM = 0.11). Immediately following each condition, 10
whole-blood RNA samples were collected from each participant, while
controlling for the effects of light, activity, and food, during a
period of total sleep deprivation. Transcriptome analysis revealed
that 711 genes were up- or down-regulated by insufficient sleep.
Insufficient sleep also reduced the number of genes with a circadian
expression profile from 1,855 to 1,481, reduced the circadian
amplitude of these genes, and led to an increase in the number of
genes that responded to subsequent total sleep deprivation from 122 to
856. Genes affected by insufficient sleep were associated with
circadian rhythms (PER1, PER2, PER3, CRY2, CLOCK, NR1D1, NR1D2, RORA,
DEC1, CSNK1E), sleep homeostasis (IL6, STAT3, KCNV2, CAMK2D),
oxidative stress (PRDX2, PRDX5), and metabolism (SLC2A3, SLC2A5, GHRL,
ABCA1). Biological processes affected included chromatin modification,
gene-expression regulation, macromolecular metabolism, and
inflammatory, immune and stress responses. Thus, insufficient sleep
affects the human blood transcriptome, disrupts its circadian
regulation, and intensifies the effects of acute total sleep
deprivation. The identified biological processes may be involved with
the negative effects of sleep loss on health, and highlight the
interrelatedness of sleep homeostasis,
circadian rhythmicity, and metabolism."

Erin C Hanlon (2021) examined diurnal patterns of AEA and 2-AG and the
possible effect of sleep deprivation. However:
"The 24-hr rhythm of AEA is markedly different from that of 2-AG,
being of lesser amplitude and biphasic, rather than monophasic. These
observations suggest distinct regulatory pathways of the two eCB and
indicate that time of day needs to be carefully controlled in studies
attempting to delineate their relative roles. Moreover, unlike 2-AG,
AEA is not altered by sleep restriction, suggesting that physiological
perturbations may affect AEA and 2-AG differently. Similar 24-hr
profiles were observed for OEA and PEA following normal and restricted
sleep, further corroborating the validity of the wave-shape and lack
of response to sleep loss observed for the AEA profile. Therapeutic
approaches involving agonism or antagonism of peripheral eCB signaling
will likely need to be tailored according to time of day."

NECUD can accelerate aging by inducing sleep deprivation. Even one
night's sleeplessness increases amyloid accumulation. [see
3557
on cannabis and amyloid clearance]. The study "β-Amyloid
accumulation in the human brain after one night of sleep deprivation"
is from Shokri-Kojori et al (2018) at the NIH Laboratory of
Neuroimaging, National Institute on Alcohol Abuse and Alcoholism:
"The effects of acute sleep deprivation on β-amyloid (Aβ)
clearance in the human brain have not been documented. Here we used
PET and 18F-florbetaben to measure brain Aβ burden (ABB) in 20
healthy controls tested after a night of rested sleep (baseline) and
after a night of sleep deprivation. We show that one night of sleep
deprivation, relative to baseline, resulted in a significant increase
in Aβ burden in the right hippocampus and thalamus. These
increases were associated with mood worsening following sleep
deprivation, but were not related to the genetic risk (APOE genotype)
for Alzheimers disease. Additionally, baseline ABB in a range of
subcortical regions and the precuneus was inversely associated with
reported night sleep hours. APOE genotyping was also linked to
subcortical ABB, suggesting that different Alzheimers disease risk
factors might independently affect ABB in nearby brain regions. In
summary, our findings show adverse effects of one-night sleep
deprivation on brain ABB and expand on prior findings of higher
Aβ accumulation with chronic less sleep."

NECUD-induced poor sleep quality could make your balls smaller. Here's
Figure 2 from one testicle study by Zhang et al (2018):

"Sleep duration and architecture were measured by actigraphy and
polysomnography, testicular volume by Prader orchidometer, total
testosterone by liquid chromatography tandem mass spectrometry, free
testosterone by equilibrium dialysis, and luteinizing hormone and
follicle-stimulating hormone (FSH) by immunochemiluminometric
assay."
They note:
"An earlier study showed inverse-U shaped relationships between sleep
duration and semen parameters and concluded that semen volume and
total sperm count fell with sleep durations less than or equal to 6.5
hours or more than 9 hours."
While...
"Testicular volumes measured by Prader orchidometer remain the
foundation of the standard andrological examination, and such
measurements have long been accepted as important clinical markers of
male fertility that correlate positively with sperm count."

Does Slovenia want or need a law to prevent the dimensional adequacy
of its testicles?
Along the way we should not exclude the possibility of cannabis
effects on semen quality. Avoiding the expectancy of preconceptions by
the use of direct measurements, Joseph et al (2025) found a similarly
non-linear association:
"Overall, 22.6% of participants reported current cannabis use and 3.3%
reported daily use. Nearly 6% of participants had low semen volume
(≤1.5 mL), 13% low sperm concentration (≤15 million/L), 8% low
TSC (≤39 million), 25% low sperm motility (≤40%), and 11% low
TMSC (≤16 million). Adjusted %Ds (95% CIs) comparing current
cannabis use versus non-use were −3.2 (−9.1, 2.7) for
semen volume, 3.5 (−10.3, 19.5) for sperm concentration,
−0.6 (−14.3, 15.3) for TSC, 2.5 (−2.9, 8.0) for
motility, and 3.0 (−13.4, 22.4) for TMSC. Cannabis use ≥1
times/week (vs. non-use) was associated with low semen volume (RR =
2.16, 95% CI = 0.935.04). Associations were imprecise and showed no
monotonic association between frequency of cannabis use and the semen
parameters evaluated.
"Conclusion
In this North American preconception cohort study, current cannabis
use was not appreciably associated with semen quality."

In 2021 scientists stumbled upon an amazing discovery for sufferers
of chronic insomnia.
Happily the restorative effect on testicles via REM sleep latency is
not confined to cannabis, as reported by Dudysov et al in Czechia in
"The Effects of Daytime Psilocybin Administration on Sleep:
Implications for Antidepressant Action" (2020):
"Serotonergic agonist psilocybin is a psychedelic with antidepressant
potential. Sleep may interact with psilocybins antidepressant
properties like other antidepressant drugs via induction of
neuroplasticity. The main aim of the study was to evaluate the effect
of psilocybin on sleep architecture on the night after psilocybin
administration. Regarding the potential antidepressant properties, we
hypothesized that psilocybin, similar to other classical
antidepressants, would reduce rapid eye movement (REM) sleep and
prolong REM sleep latency. Moreover, we also hypothesized that
psilocybin would promote slow-wave activity (SWA) expression in the
first sleep cycle, a marker of sleep-related neuroplasticity. Twenty
healthy volunteers (10 women, age 2853) underwent two drug
administration sessions, psilocybin or placebo, in a randomized,
double-blinded design. Changes in sleep macrostructure, SWA during the
first sleep cycle, whole night EEG spectral power across frequencies
in non-rapid eye movement (NREM) and REM sleep, and changes in
subjective sleep measures were analyzed. The results revealed
prolonged REM sleep latency after psilocybin administration and a
trend toward a decrease in overall REM sleep duration. No changes in
NREM sleep were observed. Psilocybin did not affect EEG power spectra
in NREM or REM sleep when examined across the whole night. However,
psilocybin suppressed SWA in the first sleep cycle. No evidence was
found for sleep-related neuroplasticity, however, a different dosage,
timing, effect on homeostatic regulation of sleep, or other mechanisms
related to antidepressant effects may play a role. Overall, this study
suggests that potential antidepressant properties of psilocybin might
be related to changes in sleep."

While the Defendant completely understand Slovenians' desire to limit

antediluvian condition of the legislative instruments compared to
these researches with implications for testicle health, I'd like to
see the ZPPPD's classification of cannabis and psychedelics justified
in the context of everything we do know about these substances and
sleep, and by extension the measurement in question.
Zhai et al (2025) examined "The Intersection of Psychedelics and
Sleep: Exploring the Impacts on Sleep Architecture, Dream States, and
Therapeutic Implications", saying:
"Psychedelics hold promise as therapeutic agents for sleep disorders
such as insomnia, PTSD, and nightmares, which are often linked to
underlying psychological conditions like anxiety, depression, and
trauma. These substances, particularly psilocybin, LSD, and DMT, may
offer novel treatment options by modulating sleep architecture,
emotional processing, and neurotransmitter activity."

In "Treating insomnia symptoms with medicinal cannabis: a randomized,
crossover trial of the efficacy of a cannabinoid medicine compared
with placebo" (2021) Walsh et al
"...employed a double-blind, randomized, placebo-controlled,
crossover design to evaluate the safety and efficacy of a cannabinoid
formulation which included THC, CBD, and CBN (ZTL-101), for treating
insomnia symptoms in patients with chronic insomnia disorder."
and
"Of the 23 participants who completed the protocol, 12 (52%) were
taking a double dose of ZTL-101 on the 14th night. Sixteen (69.5%)
were taking a double dose of placebo on the 14th night. Twenty-one of
21 participants (100%) (n = 2 missing data) guessed that they were
receiving the active medication when taking ZTL-101. 'Improvement in
sleep quality' was the reason for their guess in 17 (81%) with adverse
reactions the reason in the remaining four participants. When taking
the placebo, 18 of 23 participants (78%) thought they were receiving
placebo. Sixteen noted 'lack of improvement in sleep quality' as the
reason for their guess that they were receiving placebo."
...leading Walsh et al to conclude:
"Two weeks of nightly sublingual administration of a cannabinoid
extract (ZTL-101) is well tolerated and improves insomnia symptoms and
sleep quality in individuals with chronic insomnia symptoms."

We have a graphic from the Sleep Foundation about brain
waves:

"Alpha brain waves are the main brain wave pattern that develops when
a person becomes drowsy and transitions from wakefulness to sleep.
They continue during the early phase of sleep until they are replaced
by slower theta waves.
"Alpha waves are also present when a person is awake and relaxing,
such as with the eyes closed or during meditation Alpha wave
production is associated with states of creativity, but they tend to
disappear when a person performs mental activity requiring greater
attention."
and
"Alpha-delta sleep is an abnormal brain wave pattern associated with
certain health conditions. In alpha-delta sleep, the brain produces
alpha waves during deep sleep, when it would normally be producing
slow delta waves. The intrusion of alpha waves can make sleep
unrefreshing and leave people feeling sleepy during the day.
"Alpha-delta sleep is found in many people with fibromyalgia, a
chronic pain condition. It can also affect people with arthritis,
depression, sleep disorders, and lupus. Some evidence suggests that
alpha-delta sleep can cause pain or make pain worse for people with
fibromyalgia. But more research is needed to determine whether
alpha-delta sleep causes pain, or if it is caused by pain
instead."

Data of interest to those willing to risk illegal sleeping continued
in 2022's "Acute effects of combined cannabidiol (CBD) and
∆9-tetrahydrocannabinol (THC) in insomnia disorder: A randomised,
placebo-controlled trial using high-density EEG" by Suarez et
al:
"Compared to placebo, CBD/THC significantly decreased TST [total
sleep time] (-24.5 min, p=0.047) with no significant change to WASO
[wake after sleep onset] (+10.7 min, p=0.422). CBD/THC significantly
decreased time spent in REM (rapid eye movement] sleep (-33.9min,
p<0.001) and increased REM sleep latency (+65.6 min, p=0.008).
Preliminary high-density EEG analysis revealed increased alpha
activity during REM sleep overlying the parietal cortex (p<0.05).
CBD/THC did not impair next-day (+12 h post-treatment) cognitive
performance, alertness or simulated driving performance (all
ps>0.05). Eighty-five mild, non-serious, adverse events were
reported (55 during CBD/THC; most common dry mouth, drowsiness, and
fatigue).
"Conclusions
An acute dose of 200 mg CBD and 10 mg THC reduced TST and the time
spent in REM sleep. Analysis of all high-density EEG outcomes is
ongoing. CBD/THC did not affect next-day performance. Further research
is required to determine the impact of chronic cannabinoid dosing on
REM sleep and other objective sleep outcomes in insomnia
disorder."

"Here, we examined possible next day impairment following evening
administration of a typical medicinal cannabis oil in adults with
insomnia disorder, compared to matched placebo. This paper describes
the secondary outcomes of a larger study investigating the efects of
THC/CBD on insomnia disorder. Twenty adults [16 female; mean (SD) age,
46.1 (8.6) y] with physician-diagnosed insomnia who infrequently use
cannabis completed two 24 h in-laboratory visits involving acute oral
administration of combined 10 mg THC and 200 mg CBD (THC/CBD) or
placebo in a randomised, double-blind, crossover trial design. Outcome
measures included next day (≥9 h post-treatment) performance on
cognitive and psychomotor function tasks, simulated driving
performance, subjective drug efects, and mood. We found no diferences
in next day performance on 27 out of 28 tests of cognitive and
psychomotor function and simulated driving performance relative to
placebo. THC/CBD produced a small decrease (-1.4%, p=.016, d=-0.6) in
accuracy on the Stroop-Colour Task (easy/congruent) but not the
Stroop-Word Task (hard/incongruent). THC/ CBD also produced a small
increase (+8.6, p=.042, d=0.3) in self-ratings of Sedated at 10 h
post-treatment, but with no accompanying changes in subjective ratings
of Alert or Sleepy (ps>0.05). In conclusion, we found a lack of
notable next day impairment to cognitive and psychomotor function and
simulated driving performance following evening use of 10 mg oral THC,
in combination with 200 mg CBD, in an insomnia population who
infrequently use cannabis."

On the other hand, Suraev et al found in "Acute effects of combined
cannabidiol (CBD) and ∆9-tetrahydrocannabinol (THC) in insomnia
disorder: A randomised, placebo-controlled trial using high-density
EEG" (2022) that a high THC:CBD ratio product actually shortened total
sleep time (TST).
"Compared to placebo, CBD/THC significantly decreased TST (-24.5 min,
p=0.047) with no significant change to WASO [wake after sleep onset]
(+10.7 min, p=0.422). CBD/THC significantly decreased time spent in
REM sleep (-33.9min, p<0.001) and increased REM [rapid ey movement]
sleep latency (+65.6 min, p=0.008). Preliminary high-density EEG
analysis revealed increased alpha activity during REM sleep overlying
the parietal cortex (p<0.05). CBD/THC did not impair next-day (+12
h post-treatment) cognitive performance, alertness or simulated
driving performance (all ps>0.05). Eighty-five mild, non-serious,
adverse events were reported (55 during CBD/THC; most common dry
mouth, drowsiness, and fatigue)." [1875]
In 2024 prohibition was no longer able to prevent Arnold et al
publishing "A sleepy cannabis constituent: cannabinol and its active
metabolite influence sleep architecture in rats" in Nature:
"Medicinal cannabis is being used worldwide and there is increasing
use of novel cannabis products in the community. Cannabis contains the
major cannabinoids, Δ9-tetrahydrocannabinol (Δ9-THC) and
cannabidiol (CBD), but also an array of minor cannabinoids that have
undergone much less pharmacological characterization. Cannabinol (CBN)
is a minor cannabinoid used in the community in isolate products and
is claimed to have pro-sleep effects comparable to conventional sleep
medications. However, no study has yet examined whether it impacts
sleep architecture using objective sleep measures. The effects of CBN
on sleep in rats using polysomnography were therefore examined. CBN
increased total sleep time, although there was evidence of biphasic
effects with initial sleep suppression before a dramatic increase in
sleep. CBN increased both non-rapid eye movement (NREM) and rapid eye
movement (REM) sleep. The magnitude of the effect of CBN on NREM was
comparable to the sleep aid zolpidem, although, unlike CBN, zolpidem
did not influence REM sleep. Following CBN dosing, 11-hydroxy-CBN, a
primary metabolite of CBN surprisingly attained equivalently high
brain concentrations to CBN. 11-hydroxy-CBN was active at cannabinoid
CB1 receptors with comparable potency and efficacy to Δ9-THC,
however, CBN had much lower activity. We then discovered that the
metabolite 11-hydroxy-CBN also influenced sleep architecture, albeit
with some subtle differences from CBN itself. This study shows CBN
affects sleep using objective sleep measures and suggests an active
metabolite may contribute to its hypnotic action."

Wu et al (2025) found that "Cannabidiol regulates circadian rhythm to
improve sleep disorders following general anesthesia in rats":
"An electrode was embedded in the skull for cortical EEG recording in
24 male SD rats, which were randomized into control, propofol, CBD
treatment, and diazepam treatment groups (n=6). Eight days later, a
single dose of propofol (10 mg/kg) was injected via the tail vein with
anesthesia maintenance for 3 h in the latter 3 groups, and daily
treatment with saline, CBD or diazepam was administered via gavage;
the control rats received only saline injection. A wireless system was
used for collecting EEG, EMG, and body temperature data within 72 h
after propofol injection. After data collection, blood samples and
hypothalamic tissue samples were collected for determining serum
levels of oxidative stress markers and hypothalamic expressions of the
key clock proteins.
"Results: Compared with the control rats, the rats with CBD treatment
showed significantly increased sleep time at night (20:00-6:00),
especially during the time period of 4:00-6:00 am. Compared with the
rats in propofol group, which had prolonged SWS time and increased
sleep episodes during 18:00-24:00 and sleep-wake transitions, the
CBD-treated rats exhibited a significant reduction of SWS time and
fewer SWS-to-active-awake transitions with increased SWS aspects and
sleep-wake transitions at night (24:00-08:00). Diazepam treatment
produced similar effect to CBD but with a weaker effect on sleep-wake
transitions. Propofol caused significant changes in protein
expressions and redox state, which were effectively reversed by CBD
treatment."

According to "Pilot Study on the Effect of Cannabidiol-Coated Fabric
for Pillow Covers Improves the Sleep Quality of Shift Nurses" by Afzal
et al (2025):
"Of the 55 participants, 10 were men (18.2%) and 45 were women
(81.8%). At baseline, all participants exhibited poor sleep quality
(PSQI ≥ 5). However, after three weeks of using CBD-coated pillow
covers, subjective sleep quality significantly improved, with 7.3% of
participants achieving PSQI scores <5. Additionally, slight changes
in sleep patterns were observed, with increases in both light sleep
and deep sleep durations. Light sleep duration increased from a
baseline of 196.21 65.28 to 206.57 59.15 min two weeks after
intervention (p = 0.337). Similarly, deep sleep duration showed a
modest increase from 61.97 21.01 min to 64.35 22.19 min (p = 0.288).
Furthermore, a significant reduction in anxiety levels was reported (p
< 0.005)."

Twelve years after the ZPPPD came into force, the importance of the
glymphatic system, a CNS garbage disposal system, was discovered.
Here's a beginners' guide.
https://pmc.ncbi.nlm.nih.gov/articles/PMC4636982/
[3653]
Was General Smuts right to interfere with the human race's sleep?
Overall, authors find equivocal help with sleep from CBD but more
positive results with THC [5522]. Assistance to the recently discovered glymphatic system has
downstream benefits in dementia and cardiovascular health via improved
sleep - Hong et al (2025) find support for this in "MRI markers of
cerebrospinal fluid dynamics predict dementia and mediate the impact
of cardiovascular risk":
"Using the UK Biobank, we measured CSF dynamics: perivascular space
(PVS) volume, diffusion tensor image analysis along the PVS
(DTI-ALPS), blood oxygen leveldependent CSF (BOLD-CSF) coupling, and
choroid plexus (CP) volume. We assessed cardiovascular risk factors
and their associations with CSF dynamics and dementia based on general
practitioner, mortality, and hospital records. Mediation analysis
evaluated CSF dysfunction in cardiovascular riskdementia
relationships.
"RESULTS
Lower DTI-ALPS, lower BOLD-CSF coupling, and higher CP volume
predicted dementia, but PVS volume did not. DTI-ALPS and CP volume
mediated the effect of white matter hyperintensities and diabetes
duration on dementia.
"DISCUSSION
Impaired CSF dynamics may lead to dementia and partially mediate
cardiovascular riskdementia associations."

[5528]
In 2025 hemifusomes, a new organelle, arrived:
"Hemifusomes are fused vesicles, or sacs of fluid, that were
previously unknown to exist inside cells.
"They were discovered using cryo-electron tomography, which literally
freezes them in time, and confirmed to be actual organelles and not
just background noise.
"Because hemifusomes collect and recycle junk proteins, they could
mean more effective treatments for diseases caused and aggravated by
protein plaque buildup, such as Alzheimers."
https://www.popularmechanics.com/science/health/a65284366/new-cell-organelle/
[5148]
According to the NIH authors of the discovery:
"The pleiomorphic structure and dynamic behavior of cellular
endomembrane systems have been extensively studied using classical
electron microscopy. However, fixation and staining constraints limit
the in situ visualization of transient interactions, such as membrane
fusion, scission, and intraluminal vesicle formation, potentially
overlooking intermediate structures like membrane hemifusion. Using in
situ cryo-electron tomography in four mammalian cell lines, we
identify heterotypic hemifused vesicles featuring an extended
hemifusion diaphragm consistently associated with a 42-nanometer
proteolipid nanodroplet (PND). We designate these vesicular organelle
complexes as 'hemifusomes.' Hemifusomes constitute up to 10% of
vesicular organelles at the cell periphery but do not engage in
canonical endocytic pathways. These structures exhibit diverse
conformations and frequently contain intraluminal vesicles. Building
on the continuum of related morphologies observed, we propose that
hemifusomes serve as platforms for vesicular biogenesis, mediated by
the PND. These findings provide direct in situ evidence of long-lived
hemifused vesicle complexes and introduce an ESCRT-independent model
for multivesicular body (MVB) formation."
Asked about these and their apparent common aim with the glymphatic
system, Grok offered its opinion as follows:
"At first glance, hemifusomes and the glymphatic system operate at
different scales and contexts: hemifusomes are intracellular
organelles found across various cell types, while the glymphatic
system is a macroscopic network specific to the brains waste
clearance. However, there are intriguing points where they might
intersect or complement each other:
"Shared Goal of Waste Management:Hemifusomes are hypothesized to
recycle or dispose of cellular membranes and junk proteins within
individual cells. The glymphatic system, on the other hand, clears
interstitial waste (including proteins like amyloid-beta) from the
brains extracellular space. If hemifusomes are involved in breaking
down intracellular protein aggregates, they could feed into the
glymphatic system by preparing waste for extracellular clearance. For
instance, proteins processed by hemifusomes might be exocytosed into
the interstitial space, where the glymphatic system could then
transport them out via CSF.
"Cellular vs. Systemic Scale:
The glymphatic system relies on the coordinated action of glial cells,
blood vessels, and CSF flow, but the efficiency of this system depends
on the health of individual cells, including their ability to manage
internal waste. If hemifusomes enhance intracellular protein
recycling, they could reduce the burden on the glymphatic system by
preventing excessive waste accumulation that would otherwise need to
be cleared externally. This aligns with Ebrahims hypothesis that
hemifusomes prevent the 'buildup of stuff' that could 'gum up'
cellular operations, as noted in the Live Science article.
"Neurodegenerative Disease Link:
Both systems are relevant to neurodegenerative diseases. The
glymphatic systems role in clearing amyloid-beta during sleep is
well-documented, while hemifusomes potential to manage protein plaques
could address the intracellular origins of such aggregates. A study
from PMC on protein recycling pathways in neurodegenerative diseases
highlights how impaired intracellular mechanisms lead to aggregate
formation, suggesting that hemifusomes might act as an upstream
regulator, feeding into the glymphatic systems downstream clearance
process.
"Independence from Endosomes:
Ebrahims research indicates hemifusomes do not work with endosomes,
which are involved in endocytosis and vesicle trafficking. This
independence suggests hemifusomes might represent a novel pathway for
waste handling, potentially interfacing with the glymphatic system in
brain cells where both processes could coexist. For example,
hemifusomes might process waste internally, while the glymphatic
system handles the extracellular efflux, creating a two-tiered waste
management strategy."
And Grok's suggestions for future research as of 8 July 2025:
"To confirm any relationship, researchers could:Use cryo-ET to image
hemifusomes in brain tissue, particularly in glial cells where AQP4
channels are active.
"Track fluorescently labeled proteins processed by hemifusomes to see
if they enter the glymphatic pathway.
"Conduct longitudinal studies in mouse models, combining glymphatic
tracers with hemifusome-specific markers, to observe waste flow from
intracellular to systemic levels."

[5147]
While it is too soon to speculate on interactions between the ECS and
vesiculogenesis via hemifusomes, endocannabinoids have been shown to
have an influence on the canonical ESCRT endocytic pathways, as
DeMarino et al reported in 2022:
"Our data suggest that CBD significantly reduces the number of EVs
released from infected cells and that this may be mediated by reducing
viral transcription and autophagy activation. Therefore, CBD may exert
a protective effect by alleviating the pathogenic effects of EVs in
HIV-1 and CNS-related infections."
https://pmc.ncbi.nlm.nih.gov/articles/PMC8869966/
[5149]
And of the "Interplay between the Glymphatic System and the
Endocannabinoid System: Implications for Brain Health and Disease"
(2023) Osuna-Ramos et al say:
"The GS is subject to dynamic regulation by various factors. Sleep
plays a crucial role in modulating glymphatic function, with increased
glymphatic activity occurring during non-rapid eye movement stage 3
(NREM 3). Arousal level, blood-brain barrier (BBB) permeability, and
neurotransmitters such as norepinephrine, adenosine, and
gamma-aminobutyric acid (GABA) influence glymphatic clearance
efficiency. The GS is also influenced by vascular pulsatility, glial
cell activity, and the glymphatic-lymphatic interaction."
and
"Scientific evidence has effectively showcased the potential of
cannabinoids, both endogenous and exogenous in origin (derived from
cannabis or synthesized), in mitigating symptomatic manifestations
associated with diverse neurodegenerative ailments encompassing MS,
HD, PD, AD, and ALS. This influence may stem from their effects on the
GS, facilitating the clearance of neurotoxic substances and protein
aggregates, regulating neuroinflammatory responses, and upholding
cerebral equilibrium (Figure 2). Increased expression of cannabinoid
receptors, particularly CB2R, has been noted in human brain tissues
afflicted by ALS, MS, and AD. The interplay between the BBB and
potential shifts in the expression of cannabinoid receptors within
cerebral endothelium has been the subject of investigation.
"These insights collectively suggest that a compromised or
dysregulated ECS could potentially contribute to the symptomatology
observed in these conditions through direct modulation of the GS and
the BBB."
See the aforementioned Figure 2 for a schematic representation of the
BBB under varying conditions.

[3654]
Lundgaard et al (2018) propose "Beneficial effects of low alcohol
exposure, but adverse effects of high alcohol intake on glymphatic
function":
"Prolonged intake of excessive amounts of ethanol is known to have
adverse effects on the central nervous system (CNS). Here we
investigated the effects of acute and chronic ethanol exposure and
withdrawal from chronic ethanol exposure on glymphatic function, which
is a brain-wide metabolite clearance system connected to the
peripheral lymphatic system. Acute and chronic exposure to
1.5 g/kg (binge level) ethanol dramatically suppressed
glymphatic function in awake mice. Chronic exposure to 1.5 g/kg
ethanol increased GFAP expression and induced mislocation of the
astrocyte-specific water channel aquaporin 4 (AQP4), but decreased the
levels of several cytokines. Surprisingly, glymphatic function
increased in mice treated with 0.5 g/kg (low dose) ethanol
following acute exposure, as well as after one month of chronic
exposure. Low doses of chronic ethanol intake were associated with a
significant decrease in GFAP expression, with little change in the
cytokine profile compared with the saline group. These observations
suggest that ethanol has a J-shaped effect on the glymphatic system
whereby low doses of ethanol increase glymphatic function. Conversely,
chronic 1.5 g/kg ethanol intake induced reactive gliosis and
perturbed glymphatic function, which possibly may contribute to the
higher risk of dementia observed in heavy drinkers."

Alcohol also affects REM and slow wave sleep:
"Alcohol before sleep increased the rate of slow-wave-sleep (SWS)
accumulation across all three nights and decreased the rate of REM
sleep accumulation at the start of each night. Alcohol also decreased
the total amount of REM sleep but did not affect the total amount of
SWS each night.
"Conclusions
These data indicate that drinking alcohol before sleep substantially
affects sleep architecture, including changes to the rate of
accumulation of SWS and REM sleep. We show that alcohol disrupts
normal sleep architecture, leading to a significant decrease in REM
sleep; thus, the use of alcohol as a sleep aid remains a public health
concern."

To complete the circle, Davis et al (2025) found "Daily associations

alcohol use in veterans.
"Cannabis use is linked to reduced stress and better same-night sleep
quality.
"Stress mediates the relationship between poor sleep quality and
alcohol consumption.

A not unreasonable belief is that you might get away with less sleep
if sleep is of higher quality.
In 2000 Cantero observed:
"...transient REM-alpha bursts, which lasted about 3 s and were
accompanied by no increase in the EMG amplitude, appeared in all
subjects who participated in this study, showing a higher density in
the third and fourth REM cycle during phasic in comparison with tonic
periods. The bandpass filtered signals showed the highest spectral
contribution for the slower alpha components (8-9 Hz), the occipital
scalp regions being the main generator source of this brain
activity."
This led "Alpha burst activity during human REM sleep: descriptive
study and functional hypotheses" (2000) to conclude
"...that REM-alpha bursts may work as micro-arousals (or incomplete
arousals) facilitating the brain connection with the external world in
this cerebral state, whereas REM-alpha arousals - usually longer and
accompanied by changes in the EMG amplitude - generate a shift of
brain state associated with sleep fragmentation (complete
arousal)."
"REM-alpha bursts described in this work should not be mistaken for
arousals or, at least, for complete arousals."
https://www.sciencedirect.com/science/article/abs/pii/S1388245799003181?via%3Dihub
[3092]
And back in 1984, when government decisions about the quantity and
quality of your sleep were not perceived as an issue, Tyson et al
found:
"Alpha activity during REM sleep without signs of awakening can
discriminate between the blind classification of prelucid, lucid, and
nonlucid dreams. 10 good dream recallers (aged 1931 yrs) were aroused
after relatively high or low amplitude REM alpha. The spectral and
temporal characteristics of EEG alpha within each REM period were
associated with lucidity and other content dimensions. Each type of
dream had a reasonably distinct pattern of REM alpha. High amplitude
alpha was found to be associated with prelucid dreams and bizarre
content, which is consistent with theories of waking alpha activity
and the hypothesis that lucidity sometimes emerges from prelucid
experiences. Data are also consistent with the idea that lucidity is a
viable dream content dimension. When interpreted in terms of systems
theory, results imply that training that emphasizes dream content
control may constrain the potential information integration function
of lucid dreams."

[3092]
One thing that could keep you awake is an addiction of some kind. In
2021 when Oru Yunusoğlu at the Department of Pharmacology, Faculty of
Medicine, Bolu Abant Izzet Baysal University, Bolu, Turkey, using the
CPP technique, found that linalool has anti-addiction
properties:
"Treatment with linalool reduced the acquisition and reinstatement,
and precipitated the extinction of ethanol-induced CPP in mice.
Acquisition and reinstatement of alcohol-induced CPP were
significantly reduced by acamprosate, which also precipitated
extinction. Ethanol alone and the combination with linalool or
acamprosate did not alter locomotor activity. The results of this
study suggest that linalool may have pharmacological effects for the
treatment of alcohol addiction."
https://www.sciencedirect.com/science/article/abs/pii/S0741832921001385
[977]
An addiction not everyone goes to the doctor about.
So can linalool be bad in cannabis but good in mint? Was Plato on to
something with the kykeon?
We haven't tried to make a pill to replace a cup of tea, have
we?
So why do it to replace cannabis?
The greater good, the public good, and the good news for
pharmaceutical companies, are not continguous benefits.
So to the extent that cannabis is being used medically, cannabis
interdiction therefore represents commercial favouritism as well as
inflicting unnecessary suffering.
Thomas Clark, in "Cannabis Use Is Associated with a Substantial
Reduction in Premature Deaths in the United States", published by
Indiana University South Bend, 11 Aug. 2017, writes:
"Cannabis use prevents thousands of premature deaths each year, and
Cannabis prohibition is revealed as a major cause of premature death
in the U.S."
"Marijuana use is estimated to reduce premature deaths from diabetes
mellitus, cancer, and traumatic brain injury by 989 to 2,511 deaths
for each 1% of the population using Cannabis."
"prohibition is estimated to lead to similar numbers of premature
deaths as drunk driving, homicide, or fatal opioid overdose."
"23,500 to 47,500 deaths [would be] prevented annually if medical
marijuana were legal nationwide".
This, though, is "an underestimate" says the Professor and Chair of
the Department of Biology at South Bend Tom Clark - this is because,
and this was published August 2017, "a number of other potential
causes of reduced mortality due to Cannabis use were revealed, but
were excluded from the analysis because quantitative data were
lacking."
His estimate of the odds ratio for cancers of the head and neck is
0.83 for cannabis users.
"The relationship between Cannabis and cancer is complex. Cancer is
positively correlated with obesity, and obesity decreases in a
dose-dependent fashion with Cannabis use, whereas Cannabis smoke
contains carcinogens. On the other hand, a casual examination of the
literature reveals numerous laboratory studies demonstrating that
cannabinoids have potent anti-tumoral properties in vitro and in mouse
models. Cancers inhibited by cannabinoids include gliomas, thyroid
epithelioma, lymphoma, neuroblastoma, and carcinomas of the oral
region, lung, skin, uterus, breast, prostate, pancreas, and colon.
Thus, Cannabis may reduce the risk of getting cancer by reducing
obesity rates and by direct inhibition of tumor formation or
growth."
https://scholarworks.iu.edu/dspace/handle/2022/21632
[501]
Returning in 2021 with a broader look at cancer and cannabis data,
Clark published "Scoping Review and Meta-Analysis Suggests that
Cannabis Use May Reduce Cancer Risk in the United States":
"A total of 55 data points, consisting of risk ratios of cancer in
Cannabis users and nonusers, were identified from 34 studies. Of
these, 5 did not contain data essential for inclusion in the
meta-analysis. The remaining data showed a nonsignificant trend to an
association with reduced risk (relative risk [RR]=0.90, p>0.06,
N=50) although heterogeneity is high (I2=72.4%). Removal of data with
high risk of selection bias (defined as those from North Africa and
those that failed to adjust for tobacco) and data with high risk of
performance bias (defined as those with fewer than 20 cases or
controls among Cannabis users) resulted in an RR <1.0 (RR=0.86,
p<0.017, N=24) and large effect size (Hedges g=0.66), but did not
decrease heterogeneity (I2=74.9). Of all cancer sites, only testicular
cancer showed an RR value >1, although this was not significant and
had a negligible effect size (RR=1.12, p=0.3, Hedges g=0.02).
Following removal of testicular cancers the remaining data showed a
decrease in risk (RR=0.87, p<0.025, N=41). Cancers of the head and
neck showed a negative association with cancer risk (RR=0.83,
p<0.05), with a large effect size (Hedges g=0.55), but high
heterogeneity (I2=79.2%). RR did not reach statistical significance in
the remaining cancer site categories (lung, testicular,
obesity-associated, other). The data are consistent with a negative
association between Cannabis use and nontesticular cancer, but there
is low confidence in this result due to high heterogeneity and a
paucity of data for many cancer types."

[2779]
Clark's findings were further confirmed in a 2025 meta-analysis by
Castle et al:
"This meta-analysis was conducted to determine the scientific
consensus on medical cannabis's viability in cancer treatment.
Objective: The aim of this meta-analysis was to systematically assess
the existing literature on medical cannabis, focusing on its
therapeutic potential, safety profiles, and role in cancer treatment.
Methods: This study synthesized data from over 10,000 peer-reviewed
research papers, encompassing 39,767 data points related to cannabis
and various health outcomes. Using sentiment analysis, the study
identified correlations between cannabis use and supported, not
supported, and unclear sentiments across multiple categories,
including cancer dynamics, health metrics, and cancer treatments. A
sensitivity analysis was conducted to validate the reliability of the
findings. Results: The meta-analysis revealed a significant consensus
supporting the use of medical cannabis in the categories of health
metrics, cancer treatments, and cancer dynamics. The aggregated
correlation strength of cannabis across all cancer topics indicates
that support for medical cannabis is 31.38X stronger than opposition
to it. The analysis highlighted the anti-inflammatory potential of
cannabis, its use in managing cancer-related symptoms such as pain,
nausea, and appetite loss, and explored the consensus on its use as an
anti-carcinogenic agent.

According to "Psychedelics for Brain Injury: A Mini-Review" by Khan
et al (2021), NECUD has a poor prognosis in TBI patients:
"Presence of THC on urine drug screen is associated with decreased
mortality in adult patients sustaining TBI. However, randomized
control trials of a non-psychoactive cannabinoid analog, dexanabinol,
administered once after TBI has failed to show benefit over placebo in
increasing Glasgow Coma Scores at 6 months post-injury. One
explanation for this discrepancy may be the lack of 'entourage' effect
whereby various cannabinoids and cannabis phytochemicals are
clinically more efficacious when working synergistically compared to
administration of a single cannabinoid in isolation, though the
existence of such an effect with cannabis is contentious with mixed
evidence for its existence. Of note, an 'entourage' effect has been
demonstrated with psychedelic mushrooms in which whole mushroom
extracts are on the order of 10 times more potent than purified
psilocin administered alone in neurobehavioral rat models."

Meanwhile, "Inside One of the World's Biggest Magic Mushroom Farms",
similar issues to those of cannabis strength and nature-identicalness
have been carefully considered for the (probably US not Canadian) $22
million investment:
"The companys operation could have been much more straightforward:
Many mushroom companies just produce pure psilocybin through chemical
processes in the lab. Others simply grow mycelial grain and sell it
packaged as mushrooms. But Marshall believes that the botanical route,
to organically grow real mushrooms, is more beneficial.
To do so, the company had to invest around $22 million to create this
state-of-the-art farm. It includes rooms in which levels of humidity,
moisture, and heat can be altered to replicate the climates of places
where particular mushrooms thrive, like parts of Oregon and Costa

Shahar et al (2024) compared "Effect of chemically synthesized
psilocybin and psychedelic mushroom extract on molecular and metabolic
profiles in mouse brain":
"In most clinical studies chemically synthesized forms of these
compounds are used. Naturally occurring psychedelic compounds do not
exist in isolation but are produced by the organism as part of an
extensive milieu that includes molecules of many different types. It
is possible that these molecules exert significant biological effects
or modulate the action of the active molecule in different ways. In
regard to cannabis, it is recognized that not only cannabidiol, but a
number of other 'entourage' molecules exert significant biological
effects."
Once again, as with cannabinoids, nature did it better:
"We compared the effects of PME to those of PSIL on the head twitch
response (HTR), neuroplasticity-related synaptic proteins and frontal
cortex metabolomic profiles in male C57Bl/6j mice. HTR measurement
showed similar effects of PSIL and PME over 20 min. Brain specimens
(frontal cortex, hippocampus, amygdala, striatum) were assayed for the
synaptic proteins, GAP43, PSD95, synaptophysin and SV2A, using western
blots. These proteins may serve as indicators of synaptic plasticity.
Three days after treatment, there was minimal increase in synaptic
proteins. After 11 days, PSIL and PME significantly increased GAP43 in
the frontal cortex (p = 0.019; p = 0.039 respectively) and hippocampus
(p = 0.015; p = 0.027) and synaptophysin in the hippocampus (p =
0.041; p = 0.05) and amygdala (p = 0.035; p = 0.004). PSIL increased
SV2A in the amygdala (p = 0.036) and PME did so in the hippocampus (p
= 0.014). In the striatum, synaptophysin was increased by PME only (p
= 0.023). There were no significant effects of PSIL or PME on PSD95 in
any brain area when these were analyzed separately. Nested analysis of
variance (ANOVA) showed a significant increase in each of the 4
proteins over all brain areas for PME versus vehicle control, while
significant PSIL effects were observed only in the hippocampus and
amygdala and were limited to PSD95 and SV2A. Metabolomic analyses of
the pre-frontal cortex were performed by untargeted polar metabolomics
utilizing capillary electrophoresis Fourier transform mass
spectrometry (CE-FTMS) and showed a differential metabolic separation
between PME and vehicle groups. The purines guanosine, hypoxanthine
and inosine, associated with oxidative stress and energy production
pathways, showed a progressive decline from VEH to PSIL to PME. In
conclusion, our synaptic protein findings suggest that PME has a more
potent and prolonged effect on synaptic plasticity than PSIL. Our
metabolomics data support a gradient of effects from inert vehicle via
chemical psilocybin to PME further supporting differential effects.
Further studies are needed to confirm and extend these findings and to
identify the molecules that may be responsible for the enhanced
effects of PME as compared to psilocybin alone."
and
"The variability in effects produced mushroom extracts compared to
chemical psilocybin may be explained by differing psilocybin content
as well as by the presence and varying levels of other potentially
bioactive compounds in the different species of mushrooms. These
include tryptamines, such as 4- phosphoryloxy-N-methyltryptamine
(baeocystin), 4-phosphoryloxy-N,N,N-trimethyltryptamine
(aeruginascin), 4-hydroxy-Nmethyltryptamine (norpsilocin) and
4-phosphoryloxytryptamine (norbaeocystin) as well as β-carbolines
such as harmine and harmaline, and terpenes. Little is known about the
effects of these additional components of psychedelic mushrooms in
animal models, although there is accumulating evidence regarding the
effect of some of the tryptamines of the psilocybin biosynthetic
chain. Glatfelter et al. recently showed that only the tertiary
amines, psilocybin, psilocin, and 4- acetoxy-N,N-dimethyltryptamine
(psilacetin) induced HTR in mice while secondary amines such as
baeocystin and norpsilocin and quaternary ammonium compounds such as
aeruginascin had little or no effect. It is possible, however, that
these tryptamines present in psychedelic mushroom extracts may
modulate the effects of psilocybin. In particular, it has been
speculated that baeocystin or norpsilocin could potentially contribute
to variable subjective effects. Furthermore, additional components of
mushroom extract such as betacarbolines may exert biologically
meaningful effects in spite of their low concentrations."
https://www.nature.com/articles/s41380-024-02477-w.pdf
[3246]
"When an animal is given a drug, different metabolites accumulate as a
result of the drugs interaction with the body. Predictably, the
results showed that the extract, which included a number of compounds
in addition to psilocybin, created a larger metabolic response. But
more surprising, [Hadassah BrainLabs, a center for psychedelics
research
affiliated with Hebrew University's Bernard] Lerer says, was the
extracts effect on proteins involved in making new connections between
brain cells. 'What we found was that there is a greater production of
synaptic proteins following administration of mushroom extract
containing psilocybin than there is giving psilocybin alone,' Lerer
says. The researchers used Western blot analysis to measure synaptic
protein production. It would appear that mushroom extract increases
synaptic plasticity."
...
"Further differences between mushroom extract and synthetic psilocybin
were seen in a second study on mice. Lerer and his colleagues found
the mushroom extract produced a stronger effect on reducing behaviors
associated with anxiety than did the synthetic psilocybin. But they
found mushroom extract and synthetic psilocybin had the same effect on
reducing excessive self-grooming, a trait representing OCD. While the
study has seen some criticism for its methods and analysis, the
findings, if proven, could help demonstrate the potential for targeted
strategies using magic mushrooms to treat OCD and anxiety."
https://pubs.acs.org/doi/pdf/10.1021/acscentsci.5c01146?ref=article_openPDF
[5362]
That study, Brownstien et al (2024) "Striking long-term beneficial
effects of single dose psilocybin and psychedelic mushroom extract in
the SAPAP3 rodent model of OCD-like excessive self-grooming" relates
how...
"There is increasing interest in the use of psilocybin and other
tryptaminergic psychedelics to treat a range of psychedelic disorders
including major depression, alcohol and nicotine addiction, and end of
life anxiety. In an open study, 9 patients with OCD were administered
29 doses of psilocybin ranging from sub-hallucinogenic to frankly
hallucinogenic. Reductions in OCD symptoms were observed in all
subjects and these generally lasted for at least 24 h."
The study set out to elucidate any differences between the synthetic
psilocybin and a natural mushroom extract containing the same amount
of psilocybin, attributable to the entourage ingredients in the
extract, given to OCD-prone mice:
https://www.nature.com/articles/s41380-024-02786-0
[5363]
"Even if magic mushrooms secondary compounds are ultimately not found
to have any medical benefits, a natural product could still have
value. When psilocybin is administered medically, the patients
environment and mindset are important in the outcome of the
psychedelic trip. 'Having the participant know that this drug youre
taking came from a natural source and was actually grown and things
like that might, at least for some people, offer some reassurance in
the sometimes challenging experience,' [chief science officer at
Filament Health Ryan] Moss says."
[5362]
Addressing the problem that "few empirical studies have
systematically evaluated" the entourage effect, it became a clinical
reality three years later with the publication of "Vaporized
D-limonene selectively mitigates the acute anxiogenic effects of
Δ9-tetrahydrocannabinol in healthy adults who intermittently use
cannabis" (2024) in which Spindle et al report:
"Administration of 15 mg and 30 mg THC alone produced subjective,
cognitive, and physiological effects typical of acute cannabis
exposure. Ratings of anxiety-like subjective effects qualitatively
decreased as d-limonene dose increased and concurrent administration
of 30 mg THC+15 mg d-limonene significantly reduced ratings of
anxious/nervous and paranoid compared with 30 mg THC alone. Other
pharmacodynamic effects were unchanged by d-limonene. D-limonene
plasma concentrations were dose orderly, and concurrent administration
of d-limonene did not alter THC pharmacokinetics."
Leading to the conclusion that:
"D-limonene selectively attenuated THC-induced anxiogenic effects,
suggesting this terpenoid could increase the therapeutic index of
THC."

As for connectivity within the associative, limbic, and sensorimotor
striata, results have been mixed. A 2022 fMRI study found it reduced
less by THC+CBD than by THC alone.
No one has tested to this level for combinations of coffee and
cigarettes, nicotine and alcohol, or alcohol and caffeine.
There has been no discussion of legislating against these particular
types of alterations in connectivity, or for what reasons that might
be desirable, or how this would be measured in vivo on a continuous
basis.

Research into alcohol's effects on brain biochemistry is full of
holes. For instance Urbanik et al in Poland (2020) considered
themselves the first to examine changes in brain lipids after
administration, using proton magnetic resonance spectroscopy (1HMRS)
and diffusion weighted imaging (DWI):
"A peak corresponding to lipids (Lip) is not visible in 1H MR
spectrum of a healthy brain. In pathological conditions it reflects
either damage to cell membrane or necrosis (Cichocka and Urbanik,
2017). It was established that concentrations of lipids in tissues
correlate with the intensity of necrosis (Cichocka and Urbanik, 2017).
Lipids are visible in 1H MR spectra during ischemic stroke (Seeger et
al., 2003, Gasparovic et al., 2001). In the current study lipid
concentrations in the volunteers exposed to alcohol tended to increase
during the first hour, and then the levels started to decrease. These
changes were statistically significant, and their profile was
positively correlated to the changes in EtOH levels. No analyses of
changes in Lip levels, in relation to alcohol consumption, were found
in the available literature."

WebMD lists some physical characteristics of a genius brain.
"Signs of a Genius Brain
"There are some certain physical traits shared by the brains of
people who are geniuses or who have extreme
intelligence.
"Larger regional brain volume. Contrary to popular myth, intellect
does not result from brain size. But brain scans have shown that
gifted people or geniuses have more grey matter. This is the part of
your brain responsible for computing and processing information. It
directs your attention, memory, language, perception, and
interpretations.
"Increased brain region connectivity. Highly gifted or genius
individuals typically have more active white matter in their brains.
White matter is responsible for the communication between different
parts of your brain. Genius brains seem to have a better network of
these connections. It results in very quick and complex
thinking.
"Increased sensory sensitivity and emotional processing. Genius
brains can experience 'superstimulability.' Some genius brains are
highly sensitive to other peoples emotions. This can help relate to
other people. But at times it can be overwhelming and tiring."

Measuring white matter phospholipid damage from alcohol exposure (in
2001):
"Background: Phosphorus magnetic resonance spectroscopy (31P MRS)
allows for the measurement of phospholipids and their breakdown
products in the human brain. Fairly mobile membrane phospholipids give
rise to a broad signal that co-resonates with metabolic
phosphodiesters. Chronic alcohol exposure increases the rigidity of
isolated brain membranes and, thus, may affect the amount and
transverse relaxation times (T2) of MRS-detectable phospholipids. We
tested the hypothesis that subjects who were heavy drinkers have
stiffer membranes than controls who were light drinkers, as reflected
in a smaller broad signal component and a shorter T2 of the broad
signal in 31P MR spectra of the brain.
"Methods: Thirteen alcohol-dependent heavy drinkers (mean age 44
years) were studied by localized 31P MRS in the centrum semiovale and
compared with 17 nondependent light drinkers of similar age. The broad
component signal was separated from the metabolite signal by
convolution difference, which is based on the large difference in line
widths of these two signals. Longitudinal and T2 relaxation times were
measured using standard methods.
"Results: The broad component integral was 13% lower in the brain of
heavy drinkers compared with light drinkers (p < 0.001) and
remained significantly smaller after corrections for both longitudinal
and transverse relaxations (p < 0.01). The T2 distribution of the
broad component consistently showed two resolvable components in both
groups. The fast relaxing component had the same T2 in both groups (T2
= 1.9 msec). The slower relaxing component T2 was 0.6 msec shorter in
heavy drinkers compared with light drinkers (p = 0.08).
"Conclusions: These results, observed in the absence of white matter
volume loss, are consistent with biochemical alterations and higher
rigidity of white matter phospholipids associated with long-term
chronic alcohol abuse. The observed smaller broad signal component in
these relatively young heavy drinkers is a sensitive measure of white
matter phospholipid damage."

Happily. according to Chamoso-Sanchez (2025):
"The comprehensive characterization of cellular lipids unveiled
several classes significantly affected by CBD treatment. Most of the
differences correspond to phospholipids, including cardiolipins (CL),
phosphatidylcholines (PC) and phosphosphingolipids (SM), and also
triacylglycerols (TG), being many TG species increased after CBD
treatment in the acute and chronic models, whereas phospholipids were
found to be decreased. The results highlight some important lipid
alterations related to CBD treatment, plausibly connected with
different metabolic mechanisms involved in the process of cell death
by apoptosis in cancer cell lines."

Meanwhile, for those who just want to get high, an unpublished study
by Bosnjak et al has compared THC alone with THC plus other
CCx.
"...finding that cannabis products with a more diverse array of
natural cannabinoids produce an even stronger psychoactive experience
that lasts longer than the high generated by pure THC
products.

"The study utilized novel electroencephalogram (EEG) technology
supported by AI to quantify the high people experienced when vaping
two different products: 1) a full-spectrum live rosin with average 85
percent THC as well as other natural cannabinoids and terpenes, and 2)
a high purity THC oil with 82-85 percent potency.
The first group exhibited a considerably faster and more potent
psychoactive response compared to the latter group.
"A total of 28 adults participated in the study, strapping on the EEG
headset developed by the cannabis technology company Zentrela and
taking two hits (8 mg) of either the full-spectrum or pure THC
varieties from a vape manufactured by PAX, which also supported the
study.
"After getting a baseline reading before the participants consumed
the products, the EEG monitored activity in eight regions of the brain
over the course of 90 minutes. The tests were then converted into
psychoactive effect levels (PEL) in a standardized scale from zero
percent to 100 percent.
"The results showed that the full-spectrum live rosin with THC and
other cannabinoids and terpenes had a slightly earlier onset of three
minutes, a higher potency reading for the onset (20.8 percent) and
higher potency at the peak after 15 minutes (40 percent) and after 90
minutes (30.2 percent)."

To add to the fun, CCx do not end with cannabinoids and terpenes,
says a 2023 paper by Oswald et al:
"Here, we show that across Cannabis sativa L. varieties with
divergent aromas, terpene expression remains remarkably similar,
indicating their benign contribution to these unique, specific scents.
Instead, we found that many minor, nonterpenoid compounds correlate
strongly with nonprototypical sweet or savory aromas produced by
Cannabis sativa L. Coupling sensory studies to our chemical analysis,
we derive correlations between groups of compounds, or in some cases,
individual compounds, that produce many of these diverse scents. In
particular, we identified a new class of volatile sulfur compounds
(VSCs) containing the 3-mercaptohexyl functional group responsible for
the distinct citrus aromas in certain varieties and skatole
(3-methylindole) as the key source of the chemical aroma in others.
Our results provide not only a rich understanding of the chemistry of
Cannabis sativa L. but also highlight how the importance of terpenes
in the context of the aroma of Cannabis sativa L. has been
overemphasized."

[4049]
The indica/sativa dichotomy and talk of "strains" of cannabis is an
irrelevant distraction, says Ethan B Russo (2019):
"The Cannabis species controversy, Cannabis sativa vs. indica vs.
afghanica, has continued unabated to the current day with impassioned
arguments advanced by the protagonists (Clarke and Merlin, 2013, 2016;
Small, 2015; McPartland and Guy, 2017; Small, 2017). This author,
having been on every side of the issue at one time or another, has
chosen to eschew the irreconcilable taxonomic debate as an unnecessary
distraction (Piomelli and Russo, 2016), and rather emphasize that only
biochemical and pharmacological distinctions between Cannabis
accessions are relevant. In his recent seminal review, McPartland
agreed, “Categorizing Cannabis as either ‘Sativa’
and ‘Indica’ has become an exercise in futility.
Ubiquitous interbreeding and hybridization renders their distinction
meaningless.” (McPartland, 2018) (p. 210).
"An additional non-sensical nomenclature controversy pertains in
common parlance to Cannabis “strains,” an appellation that
is appropriate to bacteria and viruses, but not plants (Bailey and
Bailey, 1976; Usher, 1996; Brickell et al., 2009), especially so with
Cannabis where the chemical variety, abbreviated
“chemovar” is the most appropriate appellation (Lewis et
al., 2018).Further studies provide strong support for synergy:
"In a randomized controlled trial of oromucosal Cannabis-based
extracts in patients with intractable pain despite optimized opioid
treatment, a THC-predominant extract failed to demarcate favorably
from placebo, whereas a whole plant extract (nabiximols, vide infra)
with both THC and cannabidiol (CBD) proved statistically significantly
better than both (Johnson et al., 2010), the only salient difference
being the presence of CBD in the latter.
"In animal studies of analgesia, pure CBD produces a biphasic
dose-response curve such that smaller doses reduce pain responses
until a peak is reached, after which further increases in dose are
ineffective. Interestingly, the application of a full spectrum
Cannabis extract with equivalent doses of CBD eliminates the biphasic
response in favor of a linear dose-response curve such that the
botanical extract is analgesic at any dose with no observed ceiling
effect (Gallily et al., 2014).
"A recent study of several human breast cancer cell lines in culture
and implanted tumors demonstrated superiority of a Cannabis extract
treatment to pure THC, seemingly attributable in the former to the
presence of small concentrations of cannabigerol (CBG) and
tetrahydrocannabinolic acid (THCA) (Blasco-Benito et al., 2018).
"Anticonvulsant effects of cannabidiol were noted in animals in the
1970s with the first human trials in 1980 (Cunha et al., 1980). A
recent experiment in mice with seizures induced by pentylenetetrazole
employed five different Cannabis extracts with equal CBD
concentrations (Berman et al., 2018). Although all the extracts showed
benefits compared to untreated controls, salient differences were
observed in biochemical profiles of non-CBD cannabinoids, which, in
turn, led to significant differences in numbers of mice developing
tonic-clonic seizures (21.5–66.7%) and survival rates
(85–100%), highlighting the relevance of these
“minor” components. This study highlights the necessity of
standardization in pharmaceutical development, and although it could
be construed to support the single molecule therapeutic model
(Bonn-Miller et al., 2018), it requires emphasis that complex
botanicals can meet American FDA standards (Food and Drug
Administration, 2015). Specifically, two Cannabis-based drugs have
attained regulatory approval, Sativex®(nabiximols, US Adopted
Name) in 30 countries, and Epidiolex® in the United States.
"The question then arises: Can a Cannabis preparation or single
molecule be too pure, thus reducing synergistic potential? Recent data
support this as a distinct possibility. Anecdotal information from
clinicians utilizing high-CBD Cannabis extracts to treat severe
epilepsy, such as Dravet and Lennox-Gastaut syndromes, showed that
their patients demonstrated notable improvement in seizure frequency
(Goldstein, 2016; Russo, 2017; Sulak et al., 2017) with doses far
lower than those reported in formal clinical trials of Epidiolex, a
97% pure CBD preparation with THC removed (Devinsky et al., 2016,
2017, 2018; Thiele et al., 2018). This observation was recently
subjected to meta-analysis of 11 studies with 670 patients in
aggregate (Pamplona et al., 2018). Those results showed that 71% of
patients improved with CBD-predominant Cannabis extracts vs. 36% on
purified CBD (p < 0.0001). The response rate at 50% improvement in
seizure frequency was not statistically different in the two groups
and both groups achieved seizure-free status in about 10% of patients.
However, the mean daily doses were markedly divergent in the groups:
27.1 mg/kg/d for purified CBD vs. only 6.1 mg/kg/d. for CBD-rich
Cannabis extracts, a dose only 22.5% of that for CBD alone.
Furthermore, the incidence of mild and severe adverse events was
demonstrably higher in purified CBD vs. high-CBD extract patients (p
< 0.0001), a result that the authors attributed to the lower dose
utilized, which was achieved in their opinion by the synergistic
contributions of other entourage compounds. Such observations support
the hypothesis of greater efficacy for Cannabis extracts combining
multiple anticonvulsant components, such as CBD, THC, THCA, THCV,
CBDV, linalool, and even caryophyllene (Lewis et al., 2018)."
