Summary

This trial tests whether a new smartphone app called QuitQuest can help teenagers stop vaping. It compares QuitQuest to the National Cancer Institute's SmokefreeTeenQuitVaping app. The study involves teens aged 13-17 who vape regularly and want to quit. QuitQuest uses acceptance and commitment therapy to build psychological flexibility and promote behavior change, potentially offering a more effective way to help teens quit.

What this could mean

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

Active substance
Smartphone app-based behavioral intervention using Acceptance and Commitment Therapy (QuitQuest app)
What this could lead to
If effective, this app could provide a widely accessible, evidence-based tool to help teens quit vaping, reducing nicotine addiction and related health harms.
What could go wrong
The trial is early-stage and relies on self-reported abstinence, which may not always be accurate. The app may not work better than the existing standard program, and results may not generalize to all teens.

Expected to start

Dec 2026

An estimate. Start dates often move.

Expected to finish

Mar 2031

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.
