['FUNDING_R01'] · UNIVERSITY OF WISCONSIN-MADISON · NIH-11325048

What this research studies

If you both smoke combustible cigarettes and use e-cigarettes and want to quit, you could join a randomized trial of about 500 people. Participants are randomly assigned to varenicline or a nicotine patch and to counseling that either encourages quitting both products or focuses on quitting smoking while using e-cigarettes strategically, in a factorial design. The study team will keep in touch with active phone follow-up and use biochemical tests (like carbon monoxide or other assays) to check smoking abstinence. The goal is to compare combinations of medicine and counseling to identify the most helpful package for dual users.

Who could benefit from this research

Good fit: Adults who currently both smoke combustible cigarettes and use e-cigarettes, are motivated to quit smoking, and are willing to stop vaping if asked.

Not a fit: People who only vape or only smoke, those not willing to try quitting, or those with medical reasons they cannot use varenicline or nicotine patches may not benefit from this trial.

Why it matters

Potential benefit: Could identify the best medicine and counseling combination to help people who both smoke and vape quit more often.

How similar studies have performed: Medications like varenicline and nicotine patches work for cigarette-only smokers, but prior research on people who both smoke and vape is limited and mixed, so this is one of the first large randomized tests focused on dual use.
