What this research studies

If you smoke but aren’t ready to quit, you would be asked to try an app called GEMS that delivers short, self-guided exercises tailored for people ambivalent about quitting. Participants are randomly assigned to receive the GEMS app or a comparison condition and are followed over time to track smoking behavior and engagement. The app is designed to be low-cost and scalable, with content meant to increase motivation and connect users to counseling or medications when they decide they are ready. Researchers will use regular follow-up contacts to measure abstinence and other outcomes during the multi-year trial.

Who could benefit from this research

Good fit: Adults (21+) who currently smoke and feel ambivalent about quitting—meaning they are not actively seeking formal quit treatment—would be the ideal participants.

Not a fit: People without access to a smartphone, those already actively pursuing intensive quit programs, or those under 21 are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, the app could help smokers who aren’t ready to quit become more motivated and eventually stop using a low-cost, widely available tool.

How similar studies have performed: Other smartphone-based smoking-cessation programs have shown modest success, but approaches specifically targeting ambivalent smokers are newer and less proven.
