I’ve smoked weed daily for years and have done my fair share of orals over those years, but have never had liver problems even at doses that should cause them. While I won’t contribute my smoking habits entirely to my liver values, I did want to share a few studies that might be of interest to anyone who smokes weed or was looking for something to add to their liver care regiment. It’s definitely a nice bonus considering the ridiculous list of benefits weed has, especially in conjunction with gear use and the sides certain compounds can bring.

Abstract
BACKGROUND:
Abusive alcohol use has well-established health risks including causing liver disease (ALD) characterized by alcoholic steatosis (AS), steatohepatitis (AH), fibrosis, cirrhosis (AC) and hepatocellular carcinoma (HCC). Strikingly, a significant number of individuals who abuse alcohol also use Cannabis, which has seen increased legalization globally. While cannabis has demonstrated anti-inflammatory properties, its combined use with alcohol and the development of liver disease remain unclear.
AIM:
The aim of this study 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 (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.

Abstract
Cannabis use is associated with reduced prevalence of obesity and diabetes mellitus (DM) in humans and mouse disease models. Obesity and DM are a well-established independent risk factor for non-alcoholic fatty liver disease (NAFLD), the most prevalent liver disease globally. The effects of cannabis use on NAFLD prevalence in humans remains ill-defined. Our objective is to determine the relationship between cannabis use and the prevalence of NAFLD in humans. We 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 non-dependent) 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.
Endocannabinoids in Liver Disease

The ECS is present in the liver and is involved in the control of various hepatic functions with important therapeutic implications. Increased CB1 activity contributes to the hemodynamic abnormalities and promotes fibrosis in liver cirrhosis, whereas CB1 blockade attenuates and delays these changes. Endocannabinoids acting via hepatic CB1 receptors have emerged as mediators of both diet-induced and alcoholic fatty liver which, together, account for the majority of cirrhosis in Western societies. Additionally, hepatic CB1 activation contributes to obesity-related insulin- and leptin-resistance and dyslipidemias. This provides strong rationale for the therapeutic use of CB1 antagonists in these conditions. Although neuropsychiatric side effects limit the therapeutic potential of brain-penetrant CB1 antagonists, the recent emergence of second generation, peripherally-restricted CB1 antagonists may mitigate this problem. Additionally, non-psychoactive CB2 agonists may offer therapeutic benefit in attenuating liver injury and promoting tissue repair in the fibrotic liver.
