Summary

This study tested a school-based curriculum designed to prevent e-cigarette, tobacco, and betel (areca) nut use among middle school students in Guam. Over 500 students from public schools participated, with some schools receiving the new curriculum and others continuing standard education. The program included five interactive lessons with videos and cultural activities. Researchers measured changes in self-reported use and willingness to try these substances.
