This systematic review examines preclinical and clinical evidence for targeting the endocannabinoid system as a therapeutic strategy in alcohol use disorder, synthesizing findings from animal models and human studies to identify mechanisms by which cannabinoid modulators might reduce alcohol craving, consumption, and relapse risk. The review demonstrates that both direct CB1 receptor antagonism and indirect endocannabinoid system enhancement show promise in reducing alcohol-seeking behavior, though clinical translation remains limited with few well-powered human trials completed to date. Key findings suggest that endocannabinoid system dysfunction contributes to the neurobiological basis of alcohol addiction, and that cannabis or cannabinoid-based interventions may address this underlying dysregulation through multiple mechanistic pathways. However, the authors highlight significant gaps between preclinical efficacy and clinical evidence, noting that most human data comes from observational studies or small trials rather than rigorous randomized controlled designs. Clinicians should be cautious about recommending cannabis for alcohol use disorder outside of research contexts, as the evidence base remains insufficient to support routine clinical use, and patient reports of self-treatment with cannabis require careful assessment for potential drug interactions and effects on treatment engagement. The practical takeaway is that while endocannabinoid system modulation represents a biologically plausible target for alcohol use disorder, clinicians should await results from adequately powered clinical trials before considering cannabinoid-based therapies as evidence-based components of alcohol addiction treatment.
“The endocannabinoid system represents one of our most promising neurobiological targets for alcohol use disorder, and the clinical evidence suggests we’re leaving patients suffering needlessly by not integrating cannabinoid-informed treatment into our standard addiction protocols. What we see in the literature is that CBD and THC work through distinct mechanisms on the same dysregulated system that perpetuates alcohol dependence, which means we need to move beyond the false choice between pharmaceutical interventions and cannabis, and instead develop rational combination approaches based on individual patient neurobiology.”
💊 Growing preclinical evidence suggests that modulating endocannabinoid system signaling may reduce alcohol craving and relapse risk, but translation to human clinical trials remains limited and inconsistent. The endocannabinoid system’s role in reward processing and stress response is biologically plausible, yet most human studies involve small sample sizes, heterogeneous patient populations, and variable outcome measures that complicate interpretation. Important confounders include concurrent cannabis use (which itself modulates this system), genetic polymorphisms affecting cannabinoid receptors, and the challenge of isolating endocannabinoid modulation from other neurobiological changes during recovery. Rather than viewing cannabinoid-based interventions as a near-term clinical option, clinicians should recognize this as an emerging mechanistic area where well-designed randomized controlled trials are needed before recommending cannabis or synthetic cannabinoid agents to patients with alcohol use disorder.
