What this trial studies

This study aims to recruit 256 adult smokers who are willing to switch to alternative, non-combustible products. Participants will be randomly assigned to use either e-cigarettes or nicotine pouches over a 4-week period, with variations in flavor availability and nicotine concentration. They will attend bi-weekly visits to monitor their smoking behaviors and product usage, culminating in a follow-up at Week 6 to evaluate the effectiveness of the products in reducing cigarette consumption. The study is designed to identify which product characteristics are most effective in promoting smoking reduction.

Who should consider this trial

Good fit: Ideal candidates are adults aged 21 and older who currently smoke cigarettes and are not planning to use cessation therapies in the near future.

Not a fit: Patients who are currently using smoking cessation services or pharmacotherapies will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into effective alternatives for smokers looking to reduce or quit cigarette use.

How similar studies have performed: Previous studies have shown promise in using alternative nicotine products for smoking reduction, suggesting this approach may be effective.
