Δ8 -Tetrahydrocannabivarin has potent anti-nicotine effects in multiple rodent models of nicotine dependence.

British Journal of Pharmacology banner“Both types of cannabinoid receptors – CB1 and CB2 – regulate brain functions relating to addictive drug-induced reward and relapse. CB1 receptor antagonists and CB2 receptor agonists have anti-addiction efficacy, in animal models, against a broad range of addictive drugs.

Δ9 -Tetrahydrocannabivarin (Δ9 -THCV) – a cannabis constituent – acts as a CB1 antagonist and a CB2 agonist. Δ8 -Tetrahydrocannabivarin (Δ8 -THCV) is a Δ9 -THCV analogue with similar combined CB1 antagonist/CB2agonist properties.

KEY RESULTS:

Δ8 -THCV significantly attenuated intravenous nicotine self-administration, and both cue-induced and nicotine-induced relapse to nicotine-seeking behavior in rats. Δ8 -THCV also significantly attenuated nicotine-induced conditioned place preference and nicotine withdrawal in mice.

CONCLUSIONS AND IMPLICATIONS:

We conclude that Δ8 -THCV may have therapeutic potential for the treatment of nicotine dependence. We also suggest that tetrahydrocannabivarins should be tested for possible anti-addiction efficacy in a broader range of preclinical animal models, against other addictive drugs, and eventually in humans.”
