NCT ID NCT04525755
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether mailing free samples of varenicline (Chantix) or nicotine patches and lozenges helps smokers quit. 652 daily smokers were randomly assigned to receive a one-time sample of varenicline, nicotine replacement products, or no medication. Participants were not required to quit or use the samples. The study lasted 6 months and tracked smoking habits through surveys and daily diaries.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- varenicline (Chantix) and nicotine replacement therapy (patches and lozenges)
- What this could lead to
- If successful, this approach could make it easier for smokers to try quitting by offering free medication samples remotely, potentially increasing quit rates.
- What could go wrong
- This is an early-phase study with a relatively small sample. The results may not apply to all smokers, and participants were not required to quit, so the true effect on quitting is uncertain.
