(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.

Population-level evidence: among people with pre-existing SUD on GLP-1s, fewer ER visits, hospitalizations, and deaths across substance categories (observational data).
