E-Cig flavors tested as tool to cut smoking in opioid patients
NCT ID NCT07202039
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether different e-cigarette flavors can help people who smoke cigarettes and are being treated for opioid use disorder with buprenorphine to smoke fewer cigarettes. About 90 adults who smoke at least 5 cigarettes daily will try either a tobacco, sweet-cooling, or sweet non-cooling flavored e-cigarette. Researchers will track how many cigarettes they smoke over 24 weeks to see if e-cigarettes can reduce harm from smoking.
