Clinical Trial Summary

Cannabidiol is a compound found in cannabis plants that is well tolerated, has low abuse liability, and might be an effective medication to promote tobacco cessation. This clinical study will use a validated approach for screening tobacco cessation medications to determine if oral cannabidiol increases short-term tobacco abstinence, and evaluate mechanisms that might explain how cannabidiol alters smoking behavior. Results from this study will provide data on the therapeutic potential of cannabidiol for tobacco cessation.


Clinical Trial Description

Although tobacco smoking rates continue to decrease, cigarette smoking remains the leading cause of preventable disease and death in the United States and few tobacco users achieve sustained abstinence, underscoring the need for alternative treatments. The endocannabinoid system can modulate the reinforcing effects of nicotine and may be a target for development of pharmacotherapies for tobacco cessation. The cannabinoid type 1 receptor receptor inverse agonist/antagonist rimonabant has demonstrated efficacy in increasing tobacco abstinence rates in clinical trials, though it was abandoned as a viable medication due to adverse psychiatric side effects. Compounds that have similar pharmacology to rimonabant, but without the adverse psychiatric side effect profile may be efficacious for tobacco cessation. Cannabidiol (CBD) is a naturally occurring constituent of the cannabis plant that has been well tolerated in clinical studies and has low abuse liability. CBD has demonstrated anxiolytic, antipsychotic, and antidepressant effects, and can reduce appetite, suggesting that it may reduce known nicotine withdrawal symptoms associated with relapse. One clinical study provided initial evidence that CBD may be useful to promote tobacco cessation, however, the mechanism by which smoking was reduced is not clear and appropriate dosing remains unknown. This research will apply a rigorous methodological approach as an early screener for potential pharmacotherapies for tobacco dependence. This approach will utilize systematic dose administration and biochemical verification of smoking abstinence to evaluate CBD as a potential pharmacotherapy for tobacco cessation. A double-blind, within-subject, double-crossover design will be used to compare the effect of twice-daily oral CBD and matched placebo on short-term tobacco abstinence, and explore potential mechanisms underlying the effect of CBD on tobacco withdrawal, negative affect, and reinforcement. ;
