Summary

This study tests whether a short group therapy program (CBT) can help men in prison stop smoking. 202 participants will be randomly assigned to CBT, a health education session, or a waitlist. Researchers will check if they quit by measuring carbon monoxide levels at 1 and 3 months.

What this could mean

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

Active substance
Cognitive-behavioral therapy (CBT) group sessions
What this could lead to
If it works, this could provide an effective, low-cost way to help people in prison quit smoking, improving their long-term health.
What could go wrong
This is a small, early-stage trial in a specific population, so results may not apply to others. The intervention is brief (3 sessions), which may not be enough for lasting change.
