NCT ID NCT06274723
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how to present e-cigarette education messages to young adults ages 18-24 who vape or are at risk of starting. Researchers tested different message sources (expert vs. peer) and presentation styles (one-sided vs. two-sided) to see which was most accepted and increased harm perceptions. The goal is to improve public health messaging around vaping.
