About this trial

The purpose of this study is to investigate whether non-cigarette tobacco products, namely e-cigarettes (nicotine vapes), can help people who smoke and are in treatment for substance use disorder quit smoking by switching completely to e-cigarettes as compared to FDA-approved medications, namely nicotine replacement therapy in the form of patches and lozenges. Participation will last 6 months and includes 14 weekly study visits and 2 follow-up study visits (in-person, but virtual study visits are possible). Participants will also complete a short daily diary on their phones each day for the first twelve weeks. To qualify, participants (ages 21+) must be enrolled in an outpatient substance use disorder (SUD) treatment program. The study is being done in four regions across South Carolina: Charleston, Pickens/Easley, Conway, and Greenville.
