Study: CBN and THCV Effective in Reducing Alcohol Intake, Outperforming CBD
- New research from Vilnius University shows that non-psychoactive marijuana compounds—cannabinol (CBN), tetrahydrocannabivarin (THCV), and cannabidiol (CBD)—can reduce alcohol consumption in rats, with CBN and THCV being more effective than CBD.
- CBN produced a dose-dependent and lasting decrease in alcohol intake, while THCV reduced consumption primarily at higher doses; both increased water intake, indicating a targeted reduction in alcohol use.
- CBD had a limited effect on alcohol consumption and preference, and it also caused reduced locomotor activity and decreased markers of positive emotional states, differing from CBN and THCV's profiles.
- The study suggests CBN and THCV have promising potential for treating alcohol use disorder with favorable safety profiles, though further research, including human trials, is necessary.
New research published this week in Alcohol and Alcoholism and conducted by researchers from Vilnius University in Lithuania finds that certain non-psychoactive marijuana compounds may significantly reduce alcohol consumption, with some showing greater effectiveness than cannabidiol (CBD).
The study examined three phytocannabinoids—cannabinol (CBN), tetrahydrocannabivarin (THCV), and CBD—in rats with long-term voluntary alcohol use. Researchers found that all three compounds reduced alcohol intake, but CBN and THCV produced the most consistent and pronounced effects, including reductions in both alcohol consumption and preference.
CBN, a partial CB1 receptor agonist, demonstrated a dose-dependent decrease in alcohol intake that persisted for several days after treatment ended. THCV, a neutral CB1 antagonist, also reduced alcohol consumption, though its effects were somewhat less robust and primarily observed at higher doses. Both compounds also led to increased water intake, suggesting a targeted reduction in alcohol consumption rather than a general suppression of fluid intake.
CBD, by contrast, had a more limited impact. While it reduced overall alcohol intake slightly, it did not significantly affect alcohol preference or water consumption. Researchers also noted that CBD reduced locomotor activity and decreased markers associated with positive emotional states in the animals, indicating a different side effect profile compared to CBN and THCV.
Importantly, none of the compounds caused signs of distress in the animals, although mild sedative effects and small reductions in body weight were observed at higher doses.
Researchers conclude that CBN and THCV may hold stronger potential as treatments for alcohol use disorder, particularly given their effectiveness and relatively favorable safety profiles in this preclinical model. They note that further research, including human trials, will be needed to determine whether these findings translate to clinical use.
