Can cash incentives and a quit-smoking pill curb both drinking and smoking?

NCT ID NCT05181891

First seen Jul 02, 2026 · Last updated Jul 07, 2026 · Updated 2 times

Summary

This study tests whether combining varenicline (a medication that helps people stop smoking) with financial rewards for clean urine samples can reduce alcohol and tobacco use in adults who both drink heavily and smoke daily. Participants are randomly assigned to receive either rewards for negative alcohol tests or rewards just for providing samples, while all take varenicline. The goal is to see if the added incentive leads to greater reductions in drinking and smoking over several months.

varenicline
What this could lead to
If successful, this approach could offer a practical way to help people cut down on both alcohol and cigarettes at the same time.
What could go wrong
This is a mid-stage trial with 205 participants, so results may not apply to everyone. The behavioral incentives may not work long-term, and varenicline can cause side effects like nausea or mood changes.
