 GLP-1 receptor agonists show evidence across multiple substance use disorders beyond AUD: (1) Opioid Use Disorder: liraglutide produced ~40% reduction in opioid craving in small RCT; semaglutide significantly reduced opioid overdose risk in 1-year follow-up for T2D+OUD patients (real-world data). (2) Nicotine: exenatide + NRT increased 7-day abstinence vs placebo at week 6, though long-term findings mixed; SEMALCO trial showed reduced cigarettes/day as secondary endpoint in AUD+smoking subgroup. (3) Cocaine/stimulants: liraglutide reduces operant methamphetamine intake in rats (preclinical only). Population-level evidence: among people with pre-existing SUD on GLP-1s, fewer ER visits, hospitalizations, and deaths across substance categories (observational data). As of April 2026: 33 clinical trials for SUD (15 AUD, 9 nicotine, 4 OUD, 4 cocaine). Evidence strength hierarchy: AUD > OUD > nicotine > cocaine.

+Cross-substance effect consistency (OR range 0.25-0.32 across alcohol, opioid, nicotine, cocaine) supports shared mesolimbic dopamine mechanism rather than substance-specific pathways. The cocaine use disorder effect size (OR=0.25, 75% lower odds) is particularly notable—no behavioral intervention produces comparable CUD reduction, suggesting GLP-1 receptor agonists may represent the largest treatment effect for cocaine use disorder in the literature if causal relationship holds.

 Critical limitation applies across all SUD evidence: all human data comes from patients with comorbid metabolic disease (T2D or obesity). Whether GLP-1s work for SUD without metabolic comorbidity is unknown and largely unstudied. This constraint affects not just AUD but the entire SUD evidence base — OUD, nicotine, and cocaine trials all recruit from metabolically compromised populations.

+All of Us study found 74% lower odds of alcohol use disorder with GLP-1 exposure (OR=0.26, 95% CI 0.20-0.34, n=22,652 AUD cohort). Effect size larger than JAMA Psychiatry RCT (41% reduction in heavy drinking days) but observational design limits causal inference. Propensity score matching controlled for diabetes/obesity status, suggesting effect not fully explained by metabolic comorbidity.

 Observational data from 142,000 participants showed 75% lower odds of developing ANY substance use disorder with GLP-1 exposure (not just AUD). Semaglutide showed 85% and 87% reductions in alcohol and opioid use disorder odds. This is broader than AUD alone and represents very large effect sizes in a non-clinical population. Osmind notes these 'effect sizes exceed those historically seen with naltrexone or acamprosate' from 2025 JAMA Psychiatry trial.

+All of Us nested case-control study (n=87,494 across four SUD subtypes) found GLP-1 exposure associated with 75% lower odds of any substance use disorder (OR=0.25, 95% CI 0.22-0.30). Effect sizes consistent across alcohol (OR=0.26), opioid (OR=0.31), nicotine (OR=0.32), and cocaine (OR=0.25) use disorders. This represents the third independent evidence stream: (1) All of Us observational (strongest effect size, weakest design), (2) Lancet Psychiatry Swedish within-individual cohort (47% SUD worsening reduction, strongest causal design), (3) JAMA Psychiatry RCT (41% reduction heavy drinking days, gold standard). The convergence across three distinct methodologies—observational, within-individual, and RCT—with consistent direction despite different populations and outcome definitions represents the strongest pattern in the GLP-1 psychiatric evidence base.
