Summary

This study tests whether changing treatment can help smokers who relapse early after trying to quit. 544 participants who want to quit smoking will receive free nicotine patches, lozenges, varenicline, or e-cigarettes for 12 weeks. All visits are remote, and the study lasts 6 months with 8 surveys.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
nicotine replacement therapy (patches/lozenges), varenicline, or e-cigarettes
What this could lead to
If successful, this could provide a personalized strategy to help smokers who struggle to quit with standard medications.
What could go wrong
This is an early-stage behavioral study without a control group, so results may not prove which approach works best. E-cigarettes carry their own health risks.
