Summary

This study tests whether a smartphone app called Kick-Nic! can help high school students (ages 13-19) quit vaping. About 306 participants who want to quit will either use the app or visit a standard quit-vaping website for 8 weeks. Researchers will check if they've stopped vaping using self-reports and saliva tests, and follow up for 6 months.

What this could mean

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

Active substance
Kick-Nic! mobile app (behavioral intervention)
What this could lead to
If successful, this app could provide an effective, accessible tool to help teenagers quit vaping.
What could go wrong
This is a Phase 2 trial with 306 participants, so results are preliminary. The app may not outperform the control website, and long-term abstinence is hard to maintain.
