Summary

This trial tests whether training student leaders to run anti-vaping campaigns in their schools can reduce teen vaping. About 3,950 eighth and ninth graders will participate, with some schools using the peer-led approach and others not. The goal is to see if this strategy lowers the number of teens who vape, including nicotine use.

What this could mean

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

Active substance
Peer-led school-based vaping prevention campaign (Above the Influence-Vaping)
What this could lead to
If effective, this could provide a proven school-based strategy to reduce teen vaping and nicotine addiction.
What could go wrong
The trial relies on self-reported vaping, which may be underreported. Results may vary across schools and may not generalize beyond the study setting.
