Summary

This trial tests a school-based curriculum called Smart Talk, designed to reduce cannabis use and intentions among middle and high school students. Over five lessons, the program targets misperceptions, refusal skills, stress, and coping. Researchers will measure whether students' cannabis use and future intentions change after the program.

What this could mean

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

Active substance: Stanford Smart Talk Cannabis Awareness and Prevention curriculum
What this could lead to: If effective, this toolkit could provide schools with a simple, evidence-based way to reduce cannabis use and risky intentions among adolescents.
What could go wrong: This is a feasibility study, not a large-scale efficacy trial. The curriculum may not change actual behavior, and results may not generalize beyond the participating schools.
