Summary

This study tested whether regular support calls can help veterans who are not ready to quit smoking to eventually stop. Over 500 veterans received either four calls a year (enhanced care) or one call a year (standard care). The goal was to see if more calls led to more quit attempts and actual smoking abstinence after two years.

What this could mean

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

What this could lead to
If successful, this approach could point toward a low-pressure way to help veterans who are not ready to quit smoking to eventually stop.
What could go wrong
This is a completed study, but the intervention is behavioral and results may not apply to all smokers. The primary outcome relies on self-report, which can be unreliable.
