App and cash incentives aim to help menthol smokers kick the habit
NCT ID NCT07356297
First seen Jun 24, 2026 · Last updated Sep 15, 2026 · Updated 3 times
Summary
This study tests whether adding a digital incentive program to traditional quitline services helps adults who smoke menthol cigarettes quit. About 1,200 participants will use an app that rewards them for check-ins, calls to a coach, and staying smoke-free. The goal is to see if this combo works better than quitline alone.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- behavioral intervention (quitline coaching and mobile app with incentives)
- What this could lead to
- If successful, this could provide an effective, scalable way to help menthol smokers quit, reducing smoking-related diseases.
- What could go wrong
- This is a behavioral study with self-reported outcomes, so results may be less reliable. The intervention may not work for everyone, and long-term quitting success is uncertain.
