What this trial studies

This study aims to address tobacco use disorder by exploring a novel approach called practice quitting (PQ), which encourages smokers to attempt not smoking for short periods without the pressure of a permanent quit date. It will compare the effectiveness of PQ counseling against Motivational Interviewing (MI) counseling, alongside the provision of nicotine replacement therapy (NRT) samples. The study will involve 780 current smokers who are not planning to quit in the next 30 days, evaluating the impact of these interventions on the incidence of quit attempts over six months.

Why it matters

Potential benefit: If successful, this approach could significantly increase the number of smokers making quit attempts and ultimately lead to higher cessation rates.

How similar studies have gone: Previous studies have shown promise in using practice quitting as a strategy for smoking cessation, indicating potential success for this approach.
