What this research studies

This research investigates the effectiveness of varenicline, a medication commonly used for smoking cessation, in helping adults who exclusively use e-cigarettes to quit. The study will involve a randomized clinical trial with 326 participants aged 18 and older, some of whom may have a history of cigarette smoking. Participants will receive either varenicline or a placebo, and their progress will be monitored to assess changes in cancer-related biomarkers and cessation rates. The goal is to provide evidence-based methods for e-cigarette cessation, addressing a growing public health concern.

Who could benefit from this research

Good fit: Ideal candidates for this research are adults aged 18 and older who use e-cigarettes daily and are seeking to quit.

Not a fit: Patients who do not use e-cigarettes or are under 18 years old may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could provide a proven method for adults to quit e-cigarettes, potentially reducing cancer risk and improving overall health.

How similar studies have performed: Previous studies have shown promising results for varenicline in smoking cessation, suggesting potential success for its use in e-cigarette cessation as well.
