ClinConnect Summary

The STEPS trial is studying whether e-cigarettes, or nicotine vapes, can help people who smoke and are receiving treatment for substance use disorders (SUD) quit smoking. The trial compares the effectiveness of e-cigarettes to FDA-approved medications like nicotine patches and lozenges. If you participate, the study will last for 6 months and involve five in-person visits and eleven virtual check-ins. You will also keep a short daily diary on your phone for the first twelve weeks to track your progress.

To join the trial, you must be at least 21 years old, smoke at least 5 cigarettes a day for the past six months, and be within 30 days of starting an SUD treatment program. You should also have tried to quit smoking before and want to either quit or switch to a less harmful product. However, if you are pregnant, have certain medical issues, or are already using smoking cessation medications, you won't be eligible. This study is taking place at three outpatient treatment centers in South Carolina, and it aims to find better ways to help people quit smoking while they manage their substance use disorders.
