Summary

This pilot study tested a text-based program to help people gradually reduce and quit smokeless tobacco. 69 adults who used smokeless tobacco at least 3 times a day took part. For 6 weeks, everyone received automated texts to cut down. Those who didn't quit were randomly assigned to get more texts alone or texts plus a live quit coach for another 8-10 weeks. The study measured how many people enrolled, stayed, found it useful, and quit by the end.

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

Active substance

What this could lead to
If successful, this could provide a scalable, low-cost way to help people quit smokeless tobacco, especially in rural areas.
What could go wrong
This is a small pilot study (69 participants) focused on feasibility, not proof of effectiveness. Results may not apply to broader populations.
