Summary

This study tests a mobile health app designed to help young adults (ages 18-26) quit using e-cigarettes and other nicotine products. The app delivers personalized motivational messages and skills training over 6 weeks. Researchers will measure if participants stop vaping, confirmed by a mailed saliva test. The study involves 46 participants and aims to find a practical way to support quitting.

What this could mean

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

Active substance
mobile health intervention (behavioral app with motivational and skills messages)
What this could lead to
If successful, this could provide an effective, scalable tool to help young adults quit vaping and reduce nicotine addiction.
What could go wrong
This is a small pilot study (46 participants) with no control group, so results may not be generalizable. The intervention is behavioral and may not work for everyone.
