LIVER DISEASE
Following the runaway success of "alcohol use disorder" attempts to set up a
rival disorder - "cannabis use disorder" - met with little success:

Sticking to the script, Fakhoury et al (2025) found that alcoholics are less
likely to die from alcoholic liver disease (ALD) by abusing cannabis:
"Using the TriNetX US Collaborative Network, we identified adult patients with
AUD between 2010 and 2022. Three cohorts were constructed: cannabis use disorder
(CUD), cannabis users without cannabis abuse or dependence (CU) and non-cannabis
users (non-CU). Outcomes included ALD, hepatic decompensation and composite
all-cause mortality over 3 years. Incidence and hazard ratios were calculated
using Kaplan-Meier analysis and Cox regression.
"Results: After matching, 33 114 patients were included in each of the CUD and
non-CU groups. Compared to non-CU, CUD was associated with a lower risk of ALD
(HR 0.60, 95% CI 0.53-0.67; p < 0.001), hepatic decompensation (HR 0.83, 95% CI
0.73-0.95; p =0.005) and all-cause mortality (HR 0.86, 95% CI 0.80-0.94; p <
0.001) among individuals with AUD. Although CU was associated with lower risks
of ALD, its risks of hepatic decompensation and all-cause mortality were similar
to those of the non-CU cohort with AUD."
Notice how in these unpleasant results
"similar" means the same as 40%, 17%, and 14% lower risks.

Not all liver disease is exclusively
alcohol-related.
"Increased incidence of obesity and
excess weight lead to an increased incidence of non-alcoholic fatty liver
disease. FLI [Fatty Liver Index] scores than non-users (F = 13.874; p < .001).
Moreover, cannabis users less frequently met the criteria for liver steatosis
than non-users (X2 = 7.97, p = .019). Longitudinally, patients maintaining
cannabis consumption after 3 years presented the smallest increment in FLI over
time, which was significantly smaller than the increment in FLI presented by
discontinuers (p = .022) and never-users (p = .016). No differences were seen in
fibrosis scores associated with cannabis."

Castro and Abdel Bermúdez-del Sol (2025) present an alternative name for NAFLD:
"Potential associations have been investigated between metabolic
dysfunction-associated steatotic liver disease (MASLD), formerly known as
non-alcoholic fatty liver disease, and cannabis use. This study aimed to
determine the association between cannabis use frequency and MASLD. Up to
January 2025, the evidence from PubMed, Scopus, and Web of Science was
synthesized in this systematic review and meta-analysis, which was registered in
PROSPERO (CRD42025025065) and followed the Preferred Reporting Items for
Systematic reviews and Meta-Analyses (PRISMA) guidelines. Of the 711 initial
records, 11 observational studies involving 5,968,702 individuals met the
inclusion criteria. A pooled analysis revealed that cannabis use was associated
with a reduced risk of hepatic steatosis (OR = 0.58; 95% CI: 0.42-0.81; p =
0.002; I² = 97%). The subgroup analysis revealed a protective association for
past users (OR = 0.84; 95% CI: 0.77-0.93) and occasional users (OR = 0.35; 95%
CI: 0.20-0.64), with no significant association observed for frequent users. The
study revealed that cannabis users exhibited a decline in both the fatty liver
index (mean difference (MD) = -11.02) and the BMI (MD = -1.89 kg/m²). However,
the findings did not show any statistically significant changes in liver fat
(%), transaminases (aspartate aminotransferase and alanine aminotransferase),
and triglycerides. A risk-of-bias assessment identified notable methodological
limitations. Overall, the findings suggest a strong association between cannabis
use and MASLD, though causality cannot be established."

According to the BMJ:
"Nonalcoholic hepatic steatosis, or
nonalcoholic fatty liver disease (NAFLD), is one of the most common causes of
chronic liver disease in the developed world.
"It is a spectrum of disease, ranging
from hepatic fat accumulation without inflammation to steatohepatitis, fibrosis,
cirrhosis, and end-stage liver disease.
"NAFLD is considered the hepatic
manifestation of metabolic syndrome and is associated with obesity,
dyslipidemia, and type 2 diabetes mellitus.
"The diagnosis of nonalcoholic fatty
liver disease is based on exclusion of other etiologies of hepatic steatosis,
such as alcohol use, and supportive laboratory tests and imaging. Liver biopsy
and histology is the gold standard for diagnosis, and is performed for patients
at higher risk of fibrosis or steatohepatitis."
and
"Hepatic steatosis occurs when
intrahepatic fat is ≥5% of liver weight.
"Nonalcoholic fatty liver disease
(NAFLD) is evidence of hepatic steatosis (imaging or histologic) in the absence
of secondary causes of hepatic fat accumulation, such as significant alcohol
consumption.
"NAFLD can be categorized as
nonalcoholic fatty liver (NAFL) or nonalcoholic steatohepatitis (NASH),
depending on histologic features. NAFL is the presence of hepatic steatosis
without evidence of hepatocellular injury in the form of hepatocyte ballooning.
NASH is the presence of hepatic steatosis and inflammation with hepatocyte
injury (e.g., ballooning), with or without fibrosis. This distinction is
important for prognosis because NASH may progress to cirrhosis and liver
failure. The risk of NAFL progressing to cirrhosis or liver failure is minimal.
"To more accurately reflect the
pathogenesis of fatty liver, a new nomenclature of metabolic associated fatty
liver disease (MAFLD) has been suggested."

After five years of ZPPPD-inspired liver damage, the benefits of cannabis could
be inferred from studies of endocannabinoid action. In a groundbreaking step,
Osei-Hyiaman et al first demonstrated that CB1R deficiency in mice conveys a
protective effect against diet-induced hepatic steatosis, independent of caloric
intake, in "Endocannabinoid activation at hepatic CB1 receptors stimulates fatty
acid synthesis and contributes to diet-induced obesity" (2005):
"Endogenous cannabinoids acting at CB(1) receptors stimulate appetite, and CB(1)
antagonists show promise in the treatment of obesity. CB(1) (-/-) mice are
resistant to diet-induced obesity even though their caloric intake is similar to
that of wild-type mice, suggesting that endocannabinoids also regulate fat
metabolism. Here, we investigated the possible role of endocannabinoids in the
regulation of hepatic lipogenesis. Activation of CB(1) in mice increases the
hepatic gene expression of the lipogenic transcription factor SREBP-1c and its
targets acetyl-CoA carboxylase-1 and fatty acid synthase (FAS). Treatment with a
CB(1) agonist also increases de novo fatty acid synthesis in the liver or in
isolated hepatocytes, which express CB(1). High-fat diet increases hepatic
levels of the endocannabinoid anandamide (arachidonoyl ethanolamide), CB(1)
density, and basal rates of fatty acid synthesis, and the latter is reduced by
CB(1) blockade. In the hypothalamus, where FAS inhibitors elicit anorexia,
SREBP-1c and FAS expression are similarly affected by CB(1) ligands. We conclude
that anandamide acting at hepatic CB(1) contributes to diet-induced obesity and
that the FAS pathway may be a common molecular target for central appetitive and
peripheral metabolic regulation."

Even without alcoholism, liver
disease will knock nearly three years off your life:
"In this nationwide population-based
cohort, all patients with NAFLD diagnosis and without baseline CVD (ascertaining
from the Swedish National Patient Register from 1987 to 2016, n = 10,023) were
matched 10:1 on age, sex, and municipality to individuals from the general
population (controls, n = 96,313). CVD diagnosis and mortality were derived from
national registers. Multistate models and flexible parametric survival models
were used to estimate adjusted hazard ratios (aHRs) for CVD risk and loss in
life expectancy due to NAFLD. We identified 1037 (10.3%) CVD events in patients
with NAFLD and 4041 (4.2%) in controls. CVD risk was 2.6-fold higher in NAFLD
compared with controls (aHR = 2.61, 95% CI = 2.36–2.88) and was strongest for
nonfatal CVD (aHR = 3.71, 95% CI = 3.29–4.17). After a nonfatal CVD event, the
risk for all-cause mortality was similar between patients with NAFLD and
controls (aHR = 0.89, 95% CI = 0.64–1.25). Life expectancy in patients with
NAFLD was, on average, 2.8 years lower than controls, with the highest loss of
life-years when NAFLD was diagnosed in middle age (40–60 years).
"Conclusions
NAFLD was associated with a higher
risk of nonfatal CVD but did not affect post-CVD mortality risk. Patients
diagnosed with NAFLD have a lower life expectancy than the general population."
As for cardiovascular events in those
with a liver diagnosis:
"Patients with NAFLD and cirrhosis at
baseline had higher rates of all CVD events in the first model (HR 7.92, 95% CI
= 4.71–13.3), although this estimate was lower after adjustments for CVD risk
factors (aHR 2.56, 95% CI = 1.31–5.01)."
and
"Several observations can be made
from this large nationwide cohort study set in a secondary or tertiary setting.
First, we found an elevated risk of nonfatal CVD events in patients with NAFLD
compared with matched controls. Second, patients with cirrhosis had a higher CVD
risk than controls, but not compared to patients with noncirrhotic NAFLD. Third,
while NAFLD was associated with increased overall mortality, no increased
mortality was observed in patients with NAFLD with incident CVD compared to
matched controls who had also experienced a nonfatal CVD event. Finally, the
overall loss of life expectancy in patients with NAFLD was about 3 years, which
was affected by age and clinical setting at diagnosis. LEL [loss of expectancy
in life] was highest in hospitalized patients and when the diagnosis of NAFLD
was made at middle age, whereas no apparent loss in life expectancy was observed
for those aged ≥80."

In 2017's "Cannabis use is associated
with reduced prevalence of non-alcoholic fatty liver disease: A cross-sectional
study", Adejumo et al... "...conducted a population-based case-control study of
5,950,391 patients using the 2014 Healthcare Cost and Utilization Project
(HCUP), Nationwide Inpatient Survey (NIS) discharge records of patients 18 years
and older. After identifying patients with NAFLD (1% of all patients), we next
identified three exposure groups: non-cannabis users (98.04%), non-dependent
cannabis users (1.74%), and dependent cannabis users (0.22%). We adjusted for
potential demographics and patient related confounders and used multivariate
logistic regression (SAS 9.4) to determine the odds of developing NAFLD with
respects to cannabis use. Our findings revealed that cannabis users (dependent
and nondependent) showed significantly lower NAFLD prevalence compared to
non-users (AOR: 0.82[0.76–0.88]; p<0.0001). The prevalence of NAFLD was 15%
lower in non-dependent users (AOR: 0.85[0.79–0.92]; p<0.0001) and 52% lower in
dependent users (AOR: 0.49 [0.36–0.65]; p<0.0001). Among cannabis users,
dependent patients had 43% significantly lower prevalence of NAFLD compared to
non-dependent patients (AOR: 0.57[0.42–0.77]; p<0.0001). Our observations
suggest that cannabis use is associated with lower prevalence of NAFLD in
patients. These novel findings suggest additional molecular mechanistic studies
to explore the potential role of cannabis use in NAFLD development."

In 2020 Collaborators of the ANRS
CO13 HEPAVIH Study Group report:
"Mortality among individuals
co-infected with HIV and hepatitis C virus (HCV) is relatively high. We
evaluated the association between psychoactive substance use and both HCV and
non-HCV mortality in HIV/HCV co-infected patients in France, using Fine and
Gray's competing-risk model adjusted for socio-demographic, clinical predictors
and confounding factors, while accounting for competing causes of death. Over a
5-year median follow-up period, 77 deaths occurred among 1028 patients.
Regular/daily cannabis use, elevated coffee intake, and not currently smoking
were independently associated with reduced HCV-mortality (adjusted sub-hazard
ratio [95% CI] 0.28 [0.10-0.83], 0.38 [0.15-0.95], and 0.28 [0.10-0.79],
respectively). Obesity and severe thinness were associated with increased
HCV-mortality (2.44 [1.00-5.93] and 7.25 [2.22-23.6] versus normal weight,
respectively). Regular binge drinking was associated with increased
non-HCV-mortality (2.19 [1.10-4.37]). Further research is needed to understand
the causal mechanisms involved. People living with HIV/HCV co-infection should
be referred for tobacco, alcohol and weight control interventions and potential
benefits of cannabis-based therapies investigated."

From the perspective of organ damage
from alcohol, Yan et al set out to settle the vexed question of whether it is a
good idea to add cannabis to alcohol. Reporting in the Journal of Biochemical
and Molecular Toxicology:
"Cannabinoids (CBs) are psychoactive
compounds, with reported anticancer, anti-inflammatory, and anti-neoplastic
properties. The study was aimed at assessing the hepatoprotective effects of CB
against ethanol (EtOH)-induced liver toxicity in rats. The animals were divided
into seven groups: control (Group I) and Group II were treated with 50% ethanol
(EtOH 5 mg/kg). Groups III, IV, and VI were treated with (EtOH + CB 10 mg/kg),
(EtOH + CB 20 mg/kg), and (EtOH + CB 30 mg/kg), respectively. Groups V and VII
consisted of animals treated with 20 and 30 mg/kg, of CB, respectively.
Biochemical analysis revealed that Group IV (EtOH + CB 20 mg/kg) had reduced
levels of ALT—alanine transferase, AST—aspartate aminotransferase, ALP—alanine
peroxidase, MDA—malondialdehyde and increased levels of GSH-reduced glutathione.
Histopathological analysis of liver and kidney tissues showed that EtOH + CB (20
and 30 mg/kg) treated animal groups exhibited normal tissue architecture similar
to that of the control group. ELISA [enzyme-linked immunosorbent assay] revealed
that the inflammatory markers were reduced in the animal groups that were
treated with EtOH + CB 20 mg/kg, in comparison to the animals treated only with
EtOH. The mRNA expression levels of COX-2, CD-14, and MIP-2 showed a remarkable
decrease in EtOH + CB treated animal groups to control groups. Western blot
analysis revealed that CB downregulated p38/JNK/ERK thereby exhibiting its
hepatoprotective property by inhibiting mitogen-activated protein kinase
pathways. Thus, our findings suggest that CB is a potential candidate for the
treatment of alcohol-induced hepatotoxicity.

El Moneim Hussein et al of Alexandria
University in Egypt used a different experimental model of liver damage in
"Protective and therapeutic effects of cannabis plant extract on liver cancer
induced by dimethylnitrosamine in mice" (2019), finding that the Group III mice,
who received a cannabis extract with a ratio of ~2:1 THC:CBD pre-treatment in
advance of the DMNA did better than those who received cannabis with or after
the treatment, concluding:
"...exposure to DMNA plays a role in
pathogenesis of liver disease leading to carcinogenicity and causes disturbances
in the activities of mice liver enzymes while cannabis causes a partial
improvement in these enzymes. The protective effect of cannabis extract is more
pronounced than other groups and this is demonstrated in group III. Cannabinoids
might exert their anti-tumor effects by direct induction of apoptosis and can
decrease telomerase activity by inhibiting the expression of hTERT [telomerase
reverse transcriptase] gene. Coordination between inhibition of telomerase
activity and induction of apoptosis might be a potential therapeutic agent for
cancer treatment."

Glutathione exists in reduced (GSH)
and oxidized (GSSG) states. The ratio of reduced glutathione to oxidized
glutathione within cells is a measure of cellular oxidative stress where
increased GSSG-to-GSH ratio is indicative of greater oxidative stress. In
healthy cells and tissue, more than 90% of the total glutathione pool is in the
reduced form (GSH), with the remainder in the disulfide form (GSSG).
In the reduced state, the thiol group
of cysteinyl residue is a source of one reducing equivalent. Glutathione
disulfide (GSSG) is thereby generated. The oxidized state is converted to the
reduced state by NADPH. This conversion is catalyzed by glutathione reductase:
NADPH + GSSG + H2O → 2 GSH + NADP+ +
OH−

In 2011 Vara et al reported the
"Anti-tumoral action of cannabinoids on hepatocellular carcinoma: role of
AMPK-dependent activation of autophagy":
"Hepatocellular carcinoma (HCC) is
the third cause of cancer-related death worldwide. When these tumors are in
advanced stages, few therapeutic options are available. Therefore, it is
essential to search for new treatments to fight this disease. In this study, we
investigated the effects of cannabinoids--a novel family of potential anticancer
agents--on the growth of HCC. We found that Δ(9)-tetrahydrocannabinol (Δ(9)-THC,
the main active component of Cannabis sativa) and JWH-015 (a cannabinoid
receptor 2 (CB(2)) cannabinoid receptor-selective agonist) reduced the viability
of the human HCC cell lines HepG2 (human hepatocellular liver carcinoma cell
line) and HuH-7 (hepatocellular carcinoma cells), an effect that relied on the
stimulation of CB(2) receptor. We also found that Δ(9)-THC- and JWH-015-induced
autophagy relies on tribbles homolog 3 (TRB3) upregulation, and subsequent
inhibition of the serine-threonine kinase Akt/mammalian target of rapamycin C1
axis and adenosine monophosphate-activated kinase (AMPK) stimulation.
Pharmacological and genetic inhibition of AMPK upstream kinases supported that
calmodulin-activated kinase kinase β was responsible for cannabinoid-induced
AMPK activation and autophagy. In vivo studies revealed that Δ(9)-THC and
JWH-015 reduced the growth of HCC subcutaneous xenografts, an effect that was
not evident when autophagy was genetically of pharmacologically inhibited in
those tumors. Moreover, cannabinoids were also able to inhibit tumor growth and
ascites in an orthotopic model of HCC xenograft. Our findings may contribute to
the design of new therapeutic strategies for the management of HCC."

Adejumo et al have performed several
studies on the incidence of hepatic disorders and cannabis:
In 2018's "Cannabis use is associated
with reduced prevalence of progressive stages of alcoholic liver disease" the
aim was to
"...determine the effects of cannabis
use on the incidence of liver disease in individuals who abuse alcohol.
"Methods: We analysed the 2014
Healthcare Cost and Utilization Project-Nationwide Inpatient Sample (NIS)
discharge records of patients 18 years and older, who had a past or current
history of abusive alcohol use (n = 319 514). Using the International
Classification of Disease, Ninth Edition codes, we studied the four distinct
phases of progressive ALD with respect to three cannabis exposure groups:
non-cannabis users (90.39%), non-dependent cannabis users (8.26%) and dependent
cannabis users (1.36%). We accounted for the complex survey sampling methodology
and estimated the adjusted odds ratio (AOR) for developing AS, AH, AC and HCC
with respect to cannabis use (SAS 9.4).
"Results: Our study revealed that
among alcohol users, individuals who additionally use cannabis (dependent and
non-dependent cannabis use) showed significantly lower odds of developing AS,
AH, AC and HCC [alcoholic steatosis, steatohepatitis, fibrosis-cirrhosis,
hepatocellular carcinoma] (AOR: 0.55 [0.48-0.64], 0.57 [0.53-0.61], 0.45
[0.43-0.48] and 0.62 [0.51-0.76]). Furthermore, dependent users had
significantly lower odds than non-dependent users for developing liver disease.
"Conclusions: Our findings suggest
that cannabis use is associated with a reduced incidence of liver disease in
alcoholics."

In another 2018 paper Adejumo et al,
starting with 188,333 records, also looked at the effect of cannabis use on
chronic liver disease (CLD) from Hepatitis C Virus (HCV) infection, the most
common cause of CLD, and...
"...revealed that cannabis users
(CUs) had decreased prevalence of liver cirrhosis (aPRR: 0.81[0.72-0.91]),
unfavorable discharge disposition (0.87[0.78-0.96]), and lower total health care
cost ($39,642[36,220-43,387] versus $45,566[$42,244-$49,150]), compared to
noncannabis users (NCUs). However, there was no difference among CUs and NCUs on
the incidence of liver carcinoma (0.79[0.55-1.13]), in-hospital mortality
(0.84[0.60-1.17]), and LOS [length of stay] (5.58[5.10-6.09] versus
5.66[5.25-6.01]). Among CUs, dependent cannabis use was associated with lower
prevalence of liver cirrhosis, compared to nondependent use (0.62[0.41-0.93])."

"Reduced Risk of Alcohol-Induced Pancreatitis With Cannabis Use"...
"We analyzed data from 2012 to 2014
of the Healthcare Cost and Utilization Project-Nationwide Inpatient Sample
discharge records of patients 18 years and older. We used the International
Classification of Disease, Ninth Edition codes, to identify 3 populations: those
with gallstones (379,125); abusive alcohol drinkers (762,356); and
non-alcohol-non-gallstones users (15,255,464). Each study population was matched
for cannabis use record by age, race, and gender, to records without cannabis
use. The estimation of the adjusted odds ratio (aOR) of having acute and chronic
pancreatitis (AP and CP) made use of conditional logistic models.
and
"Concomitant cannabis and abusive
alcohol use were associated with reduced incidence of AP and CP (aOR: 0.50 [0.48
to 0.53] and 0.77 [0.71 to 0.84]). Strikingly, for individuals with gallstones,
additional cannabis use did not impact the incidence of AP or CP [acute and
chronic pancreatitis]. Among non‐alcohol‐non‐gallstones users, cannabis use was
associated with increased incidence of CP, but not AP (1.28 [1.14 to 1.44] and
0.93 [0.86 to 1.01]).

[5266]
In "Δ9-Tetrahydrocannabinol induces
endocannabinoid accumulation in mouse hepatocytes: antagonism by Fabp1 gene
ablation" McIntosh et al (2018) considered how
"Phytocannabinoids, such as Δ9-tetrahydrocannabinol (THC), bind and activate
cannabinoid (CB) receptors, thereby “piggy-backing” on the same pathway's
endogenous endocannabinoids (ECs). The recent discovery that liver fatty acid
binding protein-1 (FABP1) is the major cytosolic “chaperone” protein with high
affinity for both Δ9-THC and ECs suggests that Δ9-THC may alter hepatic EC
levels."
They went on to show:
"First, the phytocannabinoid CB1 agonist, Δ9-THC, significantly increased AEA
and 2-AG levels in WT hepatocytes. Consistent with this finding,
phytocannabinoids (i.e., Δ9-THC, cannabidiol) increase levels of AEA and 2-AG in
the blood and brains of humans and rodents. Because CB1 has a similar affinity
for AEA as for Δ9-THC, this suggests that Δ9-THC may, at least in part, exert
its activating effect on CB1 by increasing the hepatocytes' endogenous level of
AEA. Δ9-THC even more dramatically increased the WT hepatocyte level of 2-AG by
2-fold more than AEA. Despite CB1's weaker affinity for 2-AG than for either AEA
or Δ9-THC, 2-AG is about 3-fold more potent than AEA at CB1. While the
2-AG-induced increase in WT hepatocyte level of 2-AG may be attributable, at
least in part, to increased 2-AG available for uptake, 2-AG had no effect on the
non-ARA-containing 2-MGs, i.e., 2-OG and 2-PG, in WT hepatocytes. Taken
together, these novel observations showed that exogenously added Δ9-THC, as well
as 2-AG, increased the WT hepatocyte level of AEA and, even more so, 2-AG.
Although the hepatocytes were incubated with about 20-fold higher concentration
levels than typically observed in mouse serum after either intravenous injection
of 3 mg/kg or inhalation of 20 mg of Δ9-THC, uptake did not appear saturated
with respect to concentration.
"Second, loss of FABP1 (i.e., Fabp1 gene ablation) alone increased AEA and 2-AG
levels in cultured primary mouse hepatocytes by more than 2-fold. This finding
is physiologically significant because LKO also significantly increased AEA and
2-AG in mouse liver, albeit to a smaller extent, near 30%. In addition, LKO
concomitantly increased WT hepatocyte levels of EPEA and 2-OG by >2- and 4-fold,
respectively. A similar effect, albeit also of smaller magnitude, was also
observed in livers of LKO mice. The significance of LKO's impact on the
non-ARA-containing NAE (i.e., EPEA) and 2-MG (i.e., 2-OG) lies in their ability
to indirectly alter the effectiveness of CB1 agonists. While non-ARA-containing
NAEs (OEA, PEA) and 2-MGs (2-OG, 2-PG) do not directly bind/activate CB
receptors, they represent entourage molecules that may enhance the effects of
AEA by competing with either the transporters or the enzymes mediating the
inactivation of ECs or by enhancing binding/action of ECs, such as AEA. In
contrast, the EPA-derived EPEA displaces AEA and 2-AG from cell membranes to
reduce AEA and 2-AG release by synthetic enzymes. In fact, EPA supplementation
in humans and animals decreases 2-AG and AEA in brain and plasma. Because LKO
elicits a several-fold larger increase in hepatocyte 2-OG than EPEA, this would
suggest potential net potentiation of CB1 agonists.
"Third, LKO blocked/diminished the ability of Δ9-THC to increase both AEA and
2-AG, but, in contrast, potentiated the ability of 2-AG to increase the
hepatocyte level of AEA and 2-AG. The reasons for the opposite effects of LKO on
the ability of Δ9-THC and 2-AG to impact hepatocyte AEA and 2-AG are not
completely clear. One possibility is based on differences in CB1's and FABP1's
affinities for these ligands. For example, CB1 binds Δ9-THC with nearly 10-fold
higher affinity than for 2-AG. On the other hand FABP1 binds 2-AG with 10-fold
higher affinity than for Δ9-THC. An alternate possibility may relate to a
mechanistic difference in uptake of Δ9-THC and 2-AG. Nearly 90% of oral CB
undergoes first-pass removal by the liver by an as yet poorly understood
mechanism. Although the mechanism of EC (AEA, 2-AG) uptake across the plasma
membrane is also not completely clear, AEA uptake appears to be driven by
intracellular degradative enzymes. Much less is known about 2-AG uptake, except
that it is saturable and blocking 2-AG hydrolysis does not alter the rate of
2-AG uptake."

Alcohol reduces circulating anandamide and AEA levels are repressed in AUD. In a
2023 study by Sloan et al:
Several lines of evidence suggest that endocannabinoid signaling may influence
alcohol consumption. Preclinical studies have found that pharmacological
blockade of cannabinoid receptor 1 leads to reductions in alcohol intake.
Furthermore, variations in endocannabinoid metabolism between individuals may be
associated with the presence and severity of alcohol use disorder. However,
little is known about the acute effects of alcohol on the endocannabinoid system
in humans. In this study, we evaluated the effect of acute alcohol
administration on circulating endocannabinoid levels by analyzing data from two
highly-controlled alcohol administration experiments. In the first
within-subjects experiment, 47 healthy participants were randomized to receive
alcohol and placebo in a counterbalanced order. Alcohol was administered using
an intravenous clamping procedure such that each participant attained a nearly
identical breath alcohol concentration of 0.05%, maintained over 3 hours. In the
second experiment, 23 healthy participants self-administered alcohol
intravenously; participants had control over their exposure throughout the
paradigm. In both experiments, circulating concentrations of two
endocannabinoids, N-arachidonoylethanolamine (AEA) and 2-arachidonoylglycerol
(2-AG), were measured at baseline and following alcohol exposure. During the
intravenous clamping procedure, acute alcohol administration reduced circulating
AEA but not 2-AG levels when compared to placebo. This finding was confirmed in
the self-administration paradigm, where alcohol reduced AEA levels in an
exposure-dependent manner. Future studies should seek to determine whether
alcohol administration has similar effects on brain endocannabinoid signaling.
An improved understanding of the bidirectional relationship between
endocannabinoid signaling and alcohol intake may deepen our understanding of the
etiology and repercussions of alcohol use disorder.

The Defence believes the depressed AEA levels of chronic alcoholism shoot back
up in long-term alcohol withdrawal but may never return to baseline. According
to a review by Serrano and Natividad (2022)
"...the effects produced by chronic cannabis use returned to normal function
after a protracted abstinence period, whereas the disruptions in patients with
AUD persisted after 4 weeks of withdrawal from alcohol use. These findings
suggest that CB1 receptor downregulation is a common neuroadaptation to chronic
substance use, although seemingly more extensive under alcohol exposure than
with substances that directly interact with CB1 receptors. This may suggest that
alcohol has potent effects on the mechanisms of CB1 receptor expression and
function (e.g., signaling transduction, epigenetic changes). Alcohol is also a
notable activator of neuroinflammation, which over the course of repeated use
may temper the anti-inflammatory responses of exogenous/endogenous cannabinoid
signaling. Moreover, it is possible that alcohol may play a role in altering
endogenous mediators of cannabinoid signaling (e.g., eCBs), from which lapses in
the recovery of these signaling ligands influence the long-lasting deficits in
CB1 receptor signaling."
Table 1 summarises selected research on
alcohol and AEA and 2-AG up to then.
"Findings from the Parsons’ laboratory demonstrated that acute alcohol
self-administration elicits increases in eCB release that are tempered over
repeated exposure; however, readers are referred to the Alcohol-Induced
Alterations in Brain eCB Levels section of this review for noteworthy
distinctions. In addition, the method of alcohol exposure plays a marked role in
the subsequent analysis of abstinence-related effects. That stated, chronic
alcohol exposure is generally associated with the disruption of eCB clearance
mechanisms, impaired eCB mediated forms of synaptic plasticity, and the
downregulation of cannabinoid receptor function. The dysregulation of eCB
signaling may be relevant given that eCBs play a prominent role in the
maintenance of affective states and the constraint of stress responses, both of
which serve as provocateurs of continued use and relapse."

In the opinion of Dibba et al (2018) both CB1 and CB2 receptors have roles in
anticirrhotic mechanisms:
"Endocannabinoids, themselves also have mechanistic roles in cirrhosis.
Arachidonoyl ethanolamide (AEA) exhibits antifibrogenic properties by inhibition
of HSC proliferation and induction of necrotic death. AEA induces mesenteric
vasodilation and hypotension via CB1 induction. 2-arachidonoyl glycerol (2-AG)
is a fibrogenic mediator independent of CB receptors, but in higher doses
induces apoptosis of HSCs, which may actually show antifibrotic properties. 2-AG
has also demonstrated growth-inhibitory and cytotoxic effects. The
exocannabinoid, THC, suppresses proliferation of hepatic myofibroblasts and
stellate cells and induces apoptosis, which may reveal antifibrotic and
hepatoprotective mechanisms. Thus, several components of the endocannabinoid
system have therapeutic potential in cirrhosis."
We learn:
"Those with clinically significant disease are at risk of complications
including ascites, encephalopathy, varices, variceal hemorrhage, postsurgical
decompensation and hepatocellular carcinoma. Serum albumin, presence of
gastroesophageal varices, and Model for End-Stage Liver Disease [MELD] are
predictors of decompensation in these patients. Decompensated cirrhosis refers
to those who possess one of these complications in the setting of cirrhosis."
And in our fundamental appraisal of the dangers of NECUD in cirrhosis:
"Median survival rate for compensated cirrhotic patients ranges between 9 and 12
years. Decompensated cirrhotic patients have poor survival with a 1-year
survival rate less than 50% in patients with ascites and variceal hemorrhage."

In a 2021 paper by Sobotka et al "Cannabis
use may reduce healthcare utilization and improve hospital outcomes in patients

"Cannabis use was detected in 370 (2.1%) of 17,520 cirrhotics admitted in 2011
and in 1162 (5.3%) of 21,917 cirrhotics in 2015 (p-value <0.001). On
multivariable analysis, cirrhotics utilizing cannabis after its legalization
experienced a decreased rate of admissions related to hepatorenal syndrome (Odds
Ratio (OR): 0.51; 95% Confidence Interval (CI): 0.34−0.78) and ascites (OR:

alcohol and hepatitis C had a higher risk of admission for hepatic
encephalopathy if they utilized cannabis [OR: 1.57; 95% CI: 1.16–2.13].
Decreased length of stay (-1.15 days; 95% CI: -1.62, -0.68), total charges

By 2023 we had "Marijuana use is

the general United States population in NHANES 2017-2018: A cross-sectional

Command, Wuchangqu, Wuhan:
"A total of 2622 participants were
included in this study. The proportions of never marijuana users, past users,

marijuana users, past and current users had a lower prevalence of liver
steatosis (P = 0.184 and P = 0.048, respectively). In the alcohol
intake-adjusted model, current marijuana use was an independent predictor of a
low prevalence of liver steatosis in people with non-heavy alcohol intake. The
association between marijuana use and liver fibrosis was not significant in
univariate and multivariate regression.
"Conclusion: In this nationally

Now what is it that makes people
keep going back to the pub? Conditioned Place Preference (CPP) is one of the
most popular models to study the motivational effects of alcohol in animals.
According to Amaral et al "Susceptibility to extinction and reinstatement of
ethanol-induced conditioned place preference is related to differences in
astrocyte cystine-glutamate antiporter content":
"One important regulator of glutamate
homeostasis, maintaining extrasynaptic glutamatergic tone, is the astrocyte
cystine-glutamate antiporter (xCT). It acts by transporting one glutamate
molecule at the same time as transporting one cystine molecule. This
non-vesicular transport direction is dependent on extra and intracellular
concentrations of the substrates, transporting the substrate both to the
intracellular and the extracellular space. Since the intracellular concentration
of glutamate is much higher than that of cystine in astrocytes, xCT essentially
transports one cystine molecule to the intracellular space while transporting
one glutamate molecule to the extracellular space (Bridges et al., 2012). It is
expressed throughout the adult mouse brain, including the NAcc, the medial
prefrontal cortex (mPFC) and the amygdala (Amy) (Van Liefferinge et al., 2016).
"Recent data have shown that chronic
drug intake or withdrawal alter xCT expression in animal models of addiction.
Nicotine self-administration or inhalation through electronic cigarettes
decreases xCT expression in the striatum, ventral tegmental area (VTA), and
hippocampus (Alasmari et al., 2017; Knackstedt et al., 2009). Withdrawal from
chronic ethanol consumption decreases xCT content in the NAcc, while chronic
ethanol consumption has the opposite effect (Peana et al., 2014). In
alcohol-preferring rats, chronic ethanol consumption decreases xCT in the Amy
(Aal-Aaboda et al., 2015)."

...while Ryu et al at the Laboratory
of Liver Research, Graduate School of Medical Science and Engineering, KAIST,
Daejeon, Korea, add that:
"Chronic alcohol drinking results in
oxidative stress-mediated shortage of cysteine and thereby induces the depletion
of glutathione (GSH), which leads to the upregulation of Slc7a11 expression
(encoding xCT in system xc--cystine/glutamate antiporter) to compensate for the
cysteine shortage. Consequently, xCT-mediated glutamate excretion stimulates
metabotropic glutamate receptor 5 (mGluR5) in neighboring HSCs to produce 2-AG
in a diacylglycerol lipase-β-dependent manner. In addition, this study
demonstrated that the inhibition of the xCT and mGluR5 substantially reversed
alcohol-mediated hepatic steatosis by reducing 2-AG production in HSCs."
and writing in May 2022 they say:
"Recent studies have begun to dissect
the interaction of neurotransmitters such as endocannabinoid, glutamate and
neuroendocrine factors, and hepatic non-parenchymal cells. Signaling pathways
involved in different neurotransmitters indicate their contributions to ALD
pathogenesis."
Regarding the endocannabinoid part of
this (while avoiding cannabis completely) they announce that:
"Recent studies have suggested that
endocannabinoids and their receptors might be involved in the pathogenesis of
non-alcoholic fatty liver disease (NAFLD) and hepatic fibrosis. Extending these
findings, our studies demonstrated the pathogenic effects of endocannabinoid
2-AG and CB1 receptor in alcohol-related hepatic steatosis. In mice, chronic
alcohol consumption induces 2-AG production in HSCs [hepatic stellate cells],
which then stimulates CB1 receptor to upregulate the expression of SREBP1c
[Sterol regulatory element-binding protein 1] and FAS (CD95) [aka Fas receptor,
FasR, apoptosis antigen 1 (APO-1 or APT), cluster of differentiation 95 (CD95)
or tumor necrosis factor receptor superfamily member 6 (TNFRSF6)*] and inhibit
the activation of AMPK, enhancing fat accumulation in hepatocytes. Conversely,
treatment of rimonabant, a selective antagonist of CB1 receptor, and genetic
inhibition of CB1 receptor ameliorated alcohol-related hepatic steatosis in
mice. A recent study further supported this finding by delineating the
underlying mechanism of 2-AG production in HSCs. Chronic alcohol drinking
results in oxidative stress-mediated shortage of cysteine and thereby induces
the depletion of glutathione (GSH), which leads to the upregulation of Slc7a11
expression (encoding xCT in system xc--cystine/glutamate antiporter) to
compensate for the cysteine shortage. Consequently, xCT-mediated glutamate
excretion stimulates metabotropic glutamate receptor 5 (mGluR5) in neighboring
HSCs to produce 2-AG in a diacylglycerol lipase-β-dependent manner. In addition,
this study demonstrated that the inhibition of the xCT and mGluR5 substantially
reversed alcohol-mediated hepatic steatosis by reducing 2-AG production in HSCs.
This study also emphasized the bidirectional loop pathway where hepatocytes and
HSCs interact with each other by secreting neurotransmitters (e.g. glutamate and
2-AG) and expressing their receptors (e.g. mGluR5 and CB1), and proposed a new
concept of metabolic synapse between hepatocytes and HSCs. In contrast to CB1
receptors, CB2 receptors in KCs are known to have protective effects against
ASH. CB2 receptor activation attenuates alcohol-induced steatohepatitis and the
main mechanism is explained by paracrine interaction of endocannabinoid between
hepatocyte and Kupffer cell. The more precise mechanism has suggested that the
CB2 receptor protects the liver from steatosis by CB2-mediated autophagy in KCs
through a heme-oxygenase-1 dependent pathway, ameliorating inflammatory
responses in ALD. to produce 2-AG in a diacylglycerol lipase-β-dependent
manner."

In "Paracrine Activation of Hepatic
CB1 Receptors by Stellate Cell-Derived Endocannabinoids Mediates Alcoholic Fatty
Liver" (2008) Jeong et al
"...report that the steatosis induced
in mice by a low-fat, liquid ethanol diet is attenuated by concurrent blockade
of cannabinoid CB1 receptors. Global or hepatocyte-specific CB1 knockout mice
are resistant to ethanol-induced steatosis and increases in lipogenic gene
expression and have increased carnitine palmitoyltransferase 1 activity, which,
unlike in controls, is not reduced by ethanol treatment. Ethanol feeding
increases the hepatic expression of CB1 receptors and upregulates the
endocannabinoid 2-arachidonoylglycerol (2-AG) and its biosynthetic enzyme
diacylglycerol lipase b selectively in hepatic stellate cells. In control but
not CB1 receptor-deficient hepatocytes, coculture with stellate cells from
ethanol-fed mice results in upregulation of CB1 receptors and lipogenic gene
expression. We conclude that paracrine activation of hepatic CB1 receptors by
stellate cell-derived 2-AG mediates ethanol-induced steatosis through increasing
lipogenesis and decreasing fatty acid oxidation."
and
"Although alcoholic fatty liver is
reversible in its early stages by cessation of drinking, this is often not
feasible. The present findings suggest that treatment with a CB1 antagonist may
slow the development of steatosis and thus prevent or delay its progression to
more severe and irreversible forms of liver disease. Importantly, our finding
that the steatogenic effect of ethanol specifically involves CB1 receptors
expressed in hepatocytes suggests that selective targeting of peripheral CB1
receptors may be effective in this pathology, thereby reducing the potential for
centrally mediated adverse effects of CB1 blockade, such as anxiety and
depression (Pacher et al., 2006). The additional antifibrogenic effect of CB1
blockade could add to the benefit of such treatment."

*The Fas receptor is a death receptor

binds its ligand, Fas ligand (FasL). It is one of two apoptosis pathways, the
other being the mitochondrial pathway.
https://en.wikipedia.org/wiki/Fas_receptor [1956]
To these antisteatogenic Benedictions
we may add the deduction, from alcohol spending, of cannabis expenditure.
In support of their findings they
cite Yeong et al:
"In view of the observed upregulation
of CB1 receptors and their endogenous ligand 2-AG in ethanol-fed mice, we tested
whether activation of CB1 receptors contributes to the development of
ethanol-induced steatosis. Male mice were treated every other day with
intraperitoneal injections of vehicle or 10 mg/kg of the CB1 antagonist SR141716
(rimonabant) throughout their 3 week exposure to the ethanol-containing diet.
Body weight gain and ethanol intake were slightly lower in the rimonabanttreated
mice than in their controls, but the intake of ethanol per g of body weight was
similar in the two groups, and blood ethanol concentrations were also similar
(see Figure S1 available online). Despite this, rimonabant-treated mice were
resistant to the steatogenic effect of ethanol: their hepatic lipid content, as
verified histologically and by measuring hepatic triglyceride concentrations,
was not different from that of mice on the control liquid diet (Figures 1F and
1G), although rimonabant did not prevent the rise in plasma ALT levels."
and
"Ethanol-induced steatosis can be
prevented or reversed by in vivo treatment with AMPK activators such as
metformin (Yamauchi et al., 2002), adiponectin (Bergheim et al., 2006), or
5-aminoimidazole-4-carboxamide-1-b-D-furosamide (AICAR) (Tomita et al., 2005),
and the phytocannabinoid D9 -tetrahydrocannabinol has been shown to inhibit
hepatic AMPK activity (Kola et al., 2005)."

Kola et al indeed aver that THC
outperforms 2-AG in antisteatotic activity
"While leptin, which is associated
with appetite suppression, inhibits AMPK activity in the arcuate and
paraventricular nucleus of the hypothalamus, ghrelin has been shown to stimulate
whole hypothalamic AMPK activity after peripheral administration. In the current
study using a functional AMPK assay we observed that in whole hypothalamus total
AMPK activity increased to 153 ±8% of control after central 2-AG injection and
to 156 ±26% after i.c.v. ghrelin injection (Fig. 1A). Similar responses were
also seen after peripheral injection of THC (174 ±31% of control) and ghrelin
(177 ±12%, Fig. 1B). This increase in AMPK activity was, as expected, associated
with an increase in Thr-172 phosphorylation of AMPK (Fig. 1, C and D), while
total AMPK levels did not change in either of the tissues studied. One of the
best established downstream targets of AMPK (and therefore a good marker for
AMPK activation) is ACC. Phosphorylation by AMPK at the equivalent sites on the
two isoforms ACC1 [acetyl coenzyme A carboxylase 1] and ACC2 causes inhibition
of fatty acid synthesis and stimulation of fatty acid oxidation, respectively.
Using an antibody that detects phosphorylation of both isoforms, we detected an
increase in phosphorylation of ACC after central cannabinoid and ghrelin
treatment in the hypothalamus (Fig. 1E). We and others have described important
peripheral effects of desacyl ghrelin (see Ref. 8 and references therein),
although this form cannot activate the full-length, functionally active GHS-R1a
[growth hormone secretagogue receptor 1a]. In this study no change was observed
in hypothalamic AMPK activity (Fig. 1F) or AMPK phosphorylation (Fig. 1G) after
i.c.v. administration of desacyl ghrelin."
The effects of AMPK in the liver and
the cardiovascular system must be distinguished.
"AMPK is activated by ischemia in the
heart, leading to increased glucose uptake and phosphorylation of the
heart-specific 6-phosphofructo-2-kinase, which activates production of ATP by
glycolysis under anaerobic conditions. Activation of AMPK during ischemia also
lowers malonyl-CoA and thus increases ATP generation via fatty acid oxidation
during reperfusion. Recent results using mice expressing a dominant negative
AMPK mutant in the heart suggest that the presence of AMPK protects cardiac ATP
levels and reduces infarct size and damage to myocytes during ischemia. The lack
of fat tissue cytokine adiponectin (known to stimulate AMPK activity) results in
pressure overload and cardiac hypertrophy in “knock-out” animals, and this could
be reversed by the reintroduction of adiponectin. Recent data suggest that long
term cannabinoid treatment improves atherosclerosis via a CB2-mediated effect on
immune cells. Our present data suggest that the beneficial effects of
cannabinoids could be mediated via activation of AMPK, although excessive
activation of AMPK may be deleterious to the heart. We also found a large
increase in the phosphorylation and activity of AMPK activity in response to
ghrelin. There have been several previous studies describing the beneficial
effects of ghrelin and its synthetic analogues on cardiovascular function. These
seem to be direct effects that are independent of growth hormone release, as
positive results were obtained both in hypophysectomized rats and in in vitro
studies on embryonic (H9c2) and adult (HL-1) heart muscle cell lines. Ghrelin
and GHS-R mRNA are present in human myocardium, and protein expression has also
been detected both in primary tissue and in the HL-1 cell line, where ghrelin
has anti-apoptotic effects. Diastolic dysfunction associated with myocardial
stunning is improved with ghrelin analogue treatment. Human studies have shown
that ghrelin increases stroke volume both in healthy volunteers and in chronic
heart failure, while chronic administration of ghrelin improves left ventricular
dysfunction and attenuates the development of cardiac cachexia in rats with
heart failure. As elevated ghrelin levels have been reported in patients with
cardiac cachexia, this could be part of a compensatory mechanism in response to
catabolic-anabolic imbalance. In patients with obesity (or other
insulin-resistant states that are associated with low ghrelin levels, such as
type 2 diabetes and polycystic ovarian syndrome) the low levels of ghrelin could
contribute to heart failure, where cardiomyocyte apoptosis is known to play a
role. In contrast, the beneficial effects of weight loss on cardiac function
may, at least in part, be the result of the beneficial effects of increased
ghrelin levels."
and in sum
"We have shown that both cannabinoids
and ghrelin stimulate AMPK activity in the hypothalamus and the heart and
inhibit AMPK activity in the liver and adipose tissue, while we found no effect
on skeletal muscle. Given the proposed role of AMPK in energy sensing and
metabolism, the present findings provide important evidence of interactions
between this enzyme and the orexigenic actions of cannabinoids and ghrelin.
Either class of agent could potentially increase appetite by central AMPK
stimulation or by facilitating the restorative actions of AMPK as the
hypothalamus senses fuel deprivation. By contrast, peripheral inhibition of AMPK
by cannabinoids and ghrelin may lead to fuel, particularly fat, storage. The
combined effect of both central and peripheral signals would therefore be
increased food intake and lipid storage, leading to lipid deposition. The
cardiac and metabolic effects of cannabinoids we report may have important
implications for the anticipated widespread clinical use of rimonabant and other
CB1 antagonists in the treatment of obesity."

In 2006 Pi-Sunyer et al similarly reported positive results with this
frankencannabinoid:
"At year 1, the completion rate was 309 (51%) patients in the placebo group, 620
(51%) patients in the 5 mg of rimonabant group, and 673 (55%) patients in the 20
mg of rimonabant group. Compared with the placebo group, the 20 mg of rimonabant
group produced greater mean (SEM) reductions in weight (-6.3 [0.2] kg vs -1.6
[0.2] kg; P<.001), waist circumference (-6.1 [0.2] cm vs -2.5 [0.3] cm; P<.001),
and level of triglycerides (percentage change, -5.3 [1.2] vs 7.9 [2.0]; P<.001)
and a greater increase in level of high-density lipoprotein cholesterol
(percentage change, 12.6 [0.5] vs 5.4 [0.7]; P<.001). Patients who were switched
from the 20 mg of rimonabant group to the placebo group during year 2
experienced weight regain while those who continued to receive 20 mg of
rimonabant maintained their weight loss and favorable changes in cardiometabolic
risk factors. Use of different imputation methods to account for the high rate
of dropouts in all 3 groups yielded similar results. Rimonabant was generally
well tolerated; the most common drug-related adverse event was nausea (11.2% for
the 20 mg of rimonabant group vs 5.8% for the placebo group)."

In
2008 Kola et al
reported that "The Orexigenic Effect of Ghrelin Is Mediated through Central
Activation of the Endogenous Cannabinoid System":
"Ghrelin did not induce an orexigenic
effect in CB1-knockout mice. Correspondingly, both the genetic lack of CB1 and
the pharmacological blockade of CB1 inhibited the effect of ghrelin on AMPK
activity. Ghrelin increased the endocannabinoid content of the hypothalamus in
wild-type mice and this effect was abolished by rimonabant pre-treatment, while
no effect was observed in CB1-KO animals. Electrophysiology studies showed that
ghrelin can inhibit the excitatory inputs on the parvocellular neurons of the
paraventricular nucleus, and that this effect is abolished by administration of
a CB1 antagonist or an inhibitor of the DAG lipase, the enzyme responsible for
2-AG synthesis. The effect is also lost in the presence of BAPTA, an
intracellular calcium chelator, which inhibits endocannabinoid synthesis in the
recorded parvocellular neuron and therefore blocks the retrograde signaling
exerted by endocannabinoids. In summary, an intact cannabinoid signaling pathway
is necessary for the stimulatory effects of ghrelin on AMPK activity and food
intake, and for the inhibitory effect of ghrelin on paraventricular neurons."

Despite Rimonabant's long-concluded life as a safe and effective drug for
obesity with the unfortunate side-effect of suicidal ideation (RIP 2006-2009),
Folgueira et al were still unravelling its anorexigenic mechanism in 2017, with
"Pharmacological inhibition of cannabinoid receptor 1 stimulates gastric release
of nesfatin-1 via the mTOR pathway" contributing to a leptin-independent
understanding of satiety:
"Despite being secreted by the same cells, Nucb2 and ghrelin have opposing
biological functions and regulation. Central and peripheral administration of
Nucb2 suppresses feeding behavior, while ghrelin stimulates appetite.
Interestingly, the fact that Nucb2 and ghrelin are produced in the same gastric
cells but in different vesicles suggests that both proteins might experience
differential regulation at the gastric level to maintain energy balance.
Supporting this theory, Nucb2/nesfatin-1 production and regulation by
nutritional status decreases during fasting, while ghrelin levels are
up-regulated. Lastly, this decrease in Nucb2 production during fasting
conditions is concomitant with inhibition of the mTOR/pS6k1 pathway, a sensor of
the metabolic status of organism. Ghrelin secretion, meanwhile, is negatively
associated with mTOR/pS6k1 pathway activity under fasting conditions.
"The cannabinoid system plays an important role as an endogenous regulator of
energy balance, acting at multiple levels. One of those mechanisms includes its
interaction with gastric ghrelin production to regulate appetite and body
weight. More specifically, the blockade of the cannabinoid receptor CB1
decreases ghrelin expression in the stomach, and this effect was mediated by
activation of the mTOR/pS6k1 pathway. Taking into account the opposing functions
and regulation of ghrelin and Nucb2/nesfatin at the gastric level, as well as
their opposite relationship with the mTOR/S6K1 pathway, we sought to investigate
whether the cannabinoid system might also regulate Nucb2/nesfatin-1 production
in the stomach and whether the mTOR/pS6k1 intracellular pathway mediates this
effect."
And you can see from the title that it did.

So am I correct Slovenia is in a
battle with alcohol?
And yet as drinkers and drink
drivers, are many Slovenians not also in a psychological battle against any IDEA
disputing the idea that excess alcohol is mandatory?
And isn't their IDEA of excess "more
than I drink"?
Isn't the IDEA that cannabis is bad
supportive of alcohol profits?
Isn't the IDEA that cannabis is
protective of alcohol damage unwelcome because it not only introduces the notion
of alcohol damage, but that it must be really serious, since we already have an
IDEA of how terrible cannabis is.
For alcohol must be really bad, if we
are compelled by reason to take such a drastic leap in favour of what we have
been told is dangerous, in order to combat the alcohol folk beliefs tell us is
normal, but which is objectively 114 times worse [852].
In the area of hepatology, motivated
ignorance is fortunate: people might notice that smoking cannabis helps them
cope with a hangover, but the histology of their liver is subclinical and on a
day-by-day basis this damage is invisible to them.
According to ElTebany et al in "Lower
Rates of Hepatocellular Carcinoma Observed Among Cannabis Users: A
Population-Based Study" (2022), to more than halve your chance of hepatocellular
carcinoma, you should "abuse cannabis".
For the variables tested, only being
female gave a lower odds ratio than cannabis (0.39 versus 0.45). (Table 3).
"Using data from the National
Inpatient Sample (NIS) database between 2002 and 2014, we identified the
patients with HCC and cannabis use diagnosis using the International
Classification of Disease 9th version codes (ICD-9). Then, we identified
patients without cannabis use as the control group. We adjusted for multiple
potential confounders and performed multivariable logistic regression analysis
to determine the association between cannabis abuse and HCC.
"Results: A total of 101,231,036
patients were included in the study. Out of the total, 996,290 patients (1%) had
the diagnosis of cannabis abuse versus 100,234,746 patients (99%) in the control
group without cannabis abuse. We noticed that patients with cannabis abuse were
younger (34 vs 48 years), had more males (61.7% vs 41.4%) and more African
Americans (29.9% vs 14.2%) compared with the control group (P<0.001 for all).
Besides, patients with cannabis use had more hepatitis B, hepatitis C, liver
cirrhosis, and smoking, but had less obesity and gallstones, (P<0.001 for all).
Using multivariable logistic regression, and after adjusting for potential
confounders, patients with cannabis abuse were 55% less likely to have HCC
(adjusted Odds Ratio {aOR}, 0.45, 95% Confidence Interval {CI}, 0.42-0.49,
P<0.001) compared with patients without cannabis abuse.
"Conclusion: Based on our large
database analysis, we found that cannabis use patients were 55% less likely to
have HCC compared to patients without cannabis use."
Gallstones (ICD-9-CM cod 574) were
40% lower in the cannabis group (Table 1)
https://assets.cureus.com/uploads/original_article/pdf/90568/20220527-5140-wrns7c.pdf/www.ncbi.nlm.nih.gov/pmc/articles/PMC9138632/
[1735]
In Slovenia, there were 231 new cases
of cancer of the liver and intrahepatic bile duct in 2018, of which 126 (54.5%)
were microscopically confirmed.
https://www.onko-i.si/fileadmin/onko/datoteke/rrs/lp/Letno_porocilo_2018.pdf
[1854]
And so applying the findings of
ElTebany, of 55% less HCC in the 101,231,036 patients versus a 100% NECUD
condition, a 0% incidence of NECUD would have predicted 0.55 x 231 = 127 fewer
cases in 2018, about one case every three days.
Tajik et al found "Extracellular
vesicles of cannabis with high CBD content induce anticancer signaling in human
hepatocellular carcinoma" (2022):
"The discovery of extracellular
vesicles in the 1950s opened new insights into the understanding of
intercellular, inter-species, and inter-kingdom communications. EVs, nano-sized
bilayer lipid vesicles, are being released from different cell types and can be
classified into subgroups, namely apoptotic bodies, microvesicles, and exosomes,
according to their origin and size. Apoptotic bodies (1000–5000 nm) are being
generated from the cells that undergo apoptosis, to be phagocytosed.
Microvesicles are being originated from phospholipid membrane with a size range
of 150–1000 nm. Exosomes with 30–150 nm in size are being derived from
multi-vesicular bodies (MVBs. Naturally, EVs transfer endogenous molecules as
cargo to recipient cells. In EV-based therapeutics, molecules such as siRNA,
microRNA, as well chemicals, and biological drugs have been encapsulated within
these vehicles to be delivered to the targets of interest. Exosomes have been
considered as the promising biomarkers in the early diagnosis of diseases such
as infectious diseases, autoimmune disorders, diabetes, and several types of
cancers. Recently, large-scale production of EVs from edible and herbal plants
(range in size, 30–500 nm) has been noticed as an excellent source of
nanovesicles with phenomenal intrinsic properties and known minimal
side-effects."
and in their test comparing EVs from
high and low CBD strains, both with THC:
"Cytotoxicity assay showed that
H.C-EVs strongly decreased the viability of two hepatocellular carcinoma (HCC)
cell lines, HepG2 and Huh-7, in a dose and time-dependent manner compared with
L.C-EVs. H.C-EVs had no significant effect on HUVECs normal cell growth. The
finding showed that the H.C-EVs arrested the G0/G1 phase in the cell cycle and
significantly induced cell death by activating mitochondrial-dependent apoptosis
signaling pathways in both HCC cell lines."

Esmaeli and Dehabadi at Gerash University of Medical Sciences, Iran (2025)
reviewed 16 mixed studies on CBD and hepatocellular cancer:
"A systematic search (PubMed, Scopus, Web of Science, Google Scholar) up to
March 2025 identified 16 relevant studies (in vitro, in vivo, clinical). CBD
exerts antitumor effects via multiple pathways, including apoptosis, autophagy
regulation, metastasis suppression, and tumor microenvironment modulation. CBD
interacts with the endocannabinoid system (ECS), inhibits oncogenic signaling
(PI3K/AKT/mTOR), and enhances chemotherapeutic efficacy (sorafenib,
cabozantinib). Studies show CBD induces pyroptosis via caspase-3/GSDME, and
modulates autophagy by inhibiting the PI3K/Akt/mTOR pathway. It also sensitizes
HCC cells to sorafenib and cabozantinib. Preclinical results are promising, but
clinical studies are limited."

The Court may recall CBN was found to be beneficial to mitochondrial biogenesis
[876,877].
Akbari and Taghizadeh-Hesary (2023) looked at "COVID-19 induced liver injury
from a new perspective: Mitochondria", pointing out that:
"Patients with COVID-19 are at high risk of liver damage.
"The underlying mechanism is still undefined.
"SARS-CoV-2 can damage mitochondria directly or through systemic inflammation.
"COVID-induced liver injury is more in patients with weaker mitochondria.
"Boosting mitochondria can protect liver from COVID-induced injury."
Moreover:
"Upon entering the hepatocytes, the RNA and RNA transcripts of SARS-CoV-2
engages the mitochondria. This interaction can disrupt the mitochondrial
electron transport chain. In other words, SARS-CoV-2 hijacks the hepatocytes’
mitochondria to support its replication. In addition, this process can lead to
an improper immune response against SARS-CoV-2. Besides, this review outlines
how mitochondrial dysfunction can serve as a prelude to the COVID-associated
cytokine storm. Thereafter, we indicate how the nexus between COVID-19 and
mitochondria can fill the gap linking CiLI and its risk factors, including old
age, male sex, and comorbidities. In conclusion, this concept stresses the
importance of mitochondrial metabolism in hepatocyte damage in the context of
COVID-19. It notes that boosting mitochondria biogenesis can possibly serve as a
prophylactic and therapeutic approach for CiLI."

Huang et al (2025) examined "The protective role of cannabidiol in
stress-induced liver injury: modulating oxidative stress and mitochondrial
damage":
"CBD exhibited significant protective effects against stress-induced liver
injury in mice. Decreases in liver function indicators (including Aspartate
Aminotransferase (AST) and Alanine Aminotransferase (ALT)) and inflammatory
cytokines (such as IL-1β and Tumor Necrosis Factor-alpha (TNF-α)) were observed.
CBD enhanced CB2R expression and reduced α-SMA levels, mitigating liver
fibrosis. It also decreased ACSL4 levels, increased SOD and GSH-Px activities,
and upregulated SLC7A11 protein expression. Furthermore, CBD improved
mitochondrial morphology, indicating a reduction in oxidative cell death.
"Conclusion: CBD activates the CB2R/α-SMA pathway to modulate liver inflammation
and fibrosis. Through the SLC7A11/ACSL4 signaling pathway, CBD alleviates
oxidative stress in stress-induced liver injury, enhances mitochondrial
morphology, and reduces liver damage. These findings provide a theoretical basis
for the potential application of CBD in the prevention and treatment of
stress-induced liver injury."

Zhan et al (2025) reveal how "Cannabidiol attenuates the
LPS/D-Galactosamine-induced acute liver injury by inhibiting parkin-mediated
ubiquitination of MFN2":
"In vivo, an A-LI mouse model was induced by LPS/D-GalN. Each group was treated
with or without LPS/D-GalN or CBD. H&E staining, alanine aminotransferase (ALT),
aspartate aminotransferase (AST) level assay, TUNEL staining, TEM, IF, RT-qPCR,
Western blot, Co-IP and adeno-associated virus (AAV) infection were performed.
In vitro, RAW264.7 cells were stimulated with LPS. CCK-8, ELISA, MMP,
mitochondrial ROS assay, siRNA knockdown and plasmid overexpression were
performed.
"Results: CBD (2.5 or 5 mg kg-1) mitigated LPS/D-GalN-induced liver damage,
suppressed inflammatory cytokine expression, reduced hepatocellular apoptosis,
and inhibited oxidative stress. CBD treatment increased hepatic mitofusin-2
(MFN2) protein while decreasing Parkin-MFN2 binding and MFN2 ubiquitination. In
RAW264.7 cells, CBD pretreatment (2.5 or 5 μM) dose-dependently attenuated
LPS-induced inflammation, apoptosis, and mitochondrial dysfunction and likewise
elevated MFN2 levels while limiting its ubiquitination. MFN2 knockdown abolished
CBD's protective effects, whereas MFN2 overexpression restored them.
Consistently, AAV-mediated delivery of MFN2-targeting short hairpin RNA reversed
the hepatoprotective action of CBD in vivo.
"Conclusion: CBD mediates anti-inflammatory and hepatoprotective effects by
inhibiting MFN2 degradation through disrupting the interaction between Parkin
and MFN2."

Degrave et al (2025) examined the "Effects
of five cannabis oils with different CBD: THC ratios and terpenes on
hypertension, dyslipidemia, hepatic steatosis, oxidative stress, and CB1
receptor in an experimental model":
"Male Wistar rats were fed either a: (1) reference diet (RD; standard commercial
laboratory diet) or a: (2) sucrose-rich diet (SRD) for 3 weeks. 3 to 7 SRD + CO
as following: (3) SRD + THC; (4) SRD + CBD; (5) SRD + CBD:THC 1:1; (6)
SRD + CBD:THC 2:1; and (7) SRD + CBD:THC 3:1. The COs were administered orally
at a dose of 1.5 mg total cannabinoids/kg body weight daily. The cannabinoid and
terpenes content of all COs used in the study was determined. The terpenes found
in COs were beta-myrcene, d-limonene, terpinolene, linalool, beta-caryophyllene,
alpha-humulene, (-)-guaiol, (-)-alpha-bisabolol. During the experimental period,
body weight, food intake and blood pressure were measured. Serum glucose,
triglyceride, total cholesterol, uric acid, alanine aminotransferase (ALT),
aspartate aminotransferase (AST), and alkaline phosphatase (AP) levels were
evaluated. Liver tissue histology, NAFLD activity score (NAS), triglyceride and
cholesterol content, lipogenic enzyme activities, enzyme related to
mitochondrial fatty acid oxidation, reactive oxygen species (ROS),
thiobarbituric acid reactive substance (TBARS), and antioxidant enzyme
activities were also evaluated. The CB1 receptor expression was also determined.
"Results
The results showed that SRD-fed rats developed hypertension, dyslipidemia, liver
damage, hepatic steatosis, lipid peroxidation, and oxidative stress. This was
accompanied by upregulation of liver CB1 receptor expression. CBD-rich CO,
CBD:THC 1:1 ratio CO; CBD:THC 2:1 ratio CO and CBD:THC 3:1 ratio CO showed
antihypertensive properties. THC-rich CO, CBD:THC 1:1 ratio CO; CBD:THC 2:1
ratio CO showed the greatest beneficial effects against hepatic steatosis and
liver damage. All COs exhibited antioxidant effects in liver tissue. This was
associated with normal liver CB1 receptor expression."
...
"Figure 5A and B shows that liver ROS and TBARS were significantly increased
(P < 0.05) in the SRD group compared to the RD group. When CBD-rich CO, THC-rich
CO, CBD:THC ratio 1:1 CO, CBD:THC ratio 2:1 CO and CBD:THC ratio 3:1 CO were
administered in the SRD, these parameters decreased significantly (P < 0.05)
reaching similar values to those of the RD group. In addition, the decrease in
the GSH content in the liver of the SRD group was increased (P < 0.05) in the
SRD + CBD, SRD + THC, SRD + CBD:THC 1:1, SRD + CBD:THC 2:1 and SRD + CBD:THC 3:1
groups, reaching values similar to those of the RD group (Fig. 5C). Moreover, a
significant decrease in CAT, GPx and GR activities was observed in the SRD group
(P < 0.05). CBD-rich CO and THC-rich CO increased the CAT activity, although the
values were still lower than in the RD group. CBD:THC ratio 1:1 CO, CBD:THC 2:1
ratio CO and CBD:THC ratio 3:1 CO increased the CAT activity, reaching values
similar to those of the RD group (Fig. 5D). GR activity was increased (P < 0.05)
in SRD + CBD, SRD + THC and SRD + CBD:THC 1:1 groups, although the values were
still lower than in the RD group. In contrast, the SRD + CBD:THC 2:1 and
SRD + CBD:THC 3:1 groups showed a further increase in GR activity, reaching
levels similar to the RD group (Fig. 5E). In Fig. 5F was observed an increased
GPx activity in SRD + CBD, SRD + THC and CBD:THC 1:1 groups, reaching values
similar to those of the RD group. In SRD + CBD:THC 2:1, SRD + CBD:THC 3:1
groups, the GPx enzyme activity increased significantly, although the values
were still lower than those in the RD group."

Bader Eddin et al (2025) concentrated their attention on how "β-Caryophyllene
Ameliorates Thioacetamide-Induced Liver Fibrosis in Rats: A Preventative
Approach", describing prophylactic effects:
"The BCP treatment (50 mg/kg) protected against cell injury and potentiated
antioxidant defense by replenishing hepatic GSH, improving catalase activity,
and inhibiting the formation of MDA. The co-administration of BCP mitigated the
TAA-induced inflammatory response by decreasing the release of proinflammatory
cytokines. Histological examination showed preserved cellular integrity,
decreased collagen deposits with other extracellular matrix proteins, and low
levels of myofibroblast activation. In addition, the BCP-treated rats
demonstrated upregulated sirtuin 1 (SIRT1) expression, which had a direct
inhibitory effect on hypoxia inducible factor (HIF-1α). AM630 pre-treatment
inhibited all the aforementioned protective mechanisms of BCP. Based on our
findings, BCP exerts protective effects in liver fibrosis, which can be
attributed to its agonist action on CB2 receptors. This study provides
preclinical evidence of the potential preventative benefits of BCP in liver
fibrosis."
