Can a 4-Session class replace punishment for teen drug use?
NCT ID NCT06115746
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a 4-session drug education program called iDECIDE for middle and high school students who recently violated their school's substance use policy. About 300 students will be randomly assigned to either take the program right away or wait. Researchers will measure changes in drug knowledge, perceived harm, readiness to quit, and actual substance use over one year. The goal is to see if education can be a better alternative to punitive responses like suspension.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- iDECIDE drug education curriculum (behavioral intervention)
- What this could lead to
- If successful, this program could offer schools an effective alternative to punishment for student drug infractions, potentially reducing substance use and improving teen knowledge about drugs.
- What could go wrong
- This is an early-stage behavioral study with 300 participants, so results may not apply broadly. The program may not change actual drug use behavior, and students might not stay engaged over the year-long follow-up.
