Massive school study aims to curb teen drinking with simple conversations
NCT ID NCT06206161
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study will test whether brief, school-based conversations about alcohol can reduce drinking and drug use among high school students. Over 21,000 students across Massachusetts will be randomly assigned to different intervention approaches, including standard screening and expanded programs. Researchers will track alcohol, cannabis, and nicotine use over two years to see which methods work best.
