Summary

This study compares two approaches to help people with serious mental illness reduce their cigarette smoking: using e-cigarettes or nicotine patches and lozenges, combined with counseling. Sixty participants who smoke at least 5 cigarettes a day will be randomly assigned to one of the two groups. The goal is to see which method leads to a greater reduction in smoking over 8 weeks.

What this could mean

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

Active substance
e-cigarette (NJOY Ace) and nicotine replacement therapy (patch and lozenges)
What this could lead to
If successful, this could show that e-cigarettes are a more effective harm-reduction tool than nicotine patches for people with serious mental illness who smoke.
What could go wrong
This is a small, early-stage trial with only 60 participants, so results may not apply to everyone. The study relies on self-reported smoking, which can be inaccurate.
