Can CBD help treat addiction to other substances?
Research-Based Answer
CBD is being actively investigated as a treatment for multiple substance use disorders. For opioid addiction: a 2019 RCT (Hurd et al., American Journal of Psychiatry) found CBD 400–800mg/day significantly reduced cue-induced craving and anxiety in heroin-abstinent individuals — the most rigorous evidence to date. For cannabis use disorder: CBD has shown promise in reducing cannabis use and withdrawal symptoms in small trials. For alcohol use disorder: preclinical evidence is strong (CBD reduces alcohol intake in animal models), but human RCT data are limited. For tobacco: a 2013 pilot RCT found CBD inhaler reduced cigarette consumption by 40% vs. placebo. The mechanisms likely involve CBD's effects on stress reactivity, anxiety, and cue-induced craving via 5-HT1A and TRPV1 pathways.
