Phase 2 RCT (exenatide + NRT) showed increased smoking abstinence vs. placebo + NRT, with reduced cravings and withdrawal symptoms. However, dulaglutide + varenicline RCT showed null result, likely due to ceiling effect (adding GLP-1 to already-effective varenicline). Mechanism consistent with VTA dopamine pathway modulation.
