Summary

This study is developing and testing a brief online program for young adult couples (ages 18-29) who use both alcohol and cannabis. The program aims to reduce risky substance use and improve relationship skills. Sixty couples in Washington State will be randomly assigned to either the online program or a no-intervention control group, and researchers will compare changes in drinking, cannabis use, and relationship satisfaction over three months.

What this could mean

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

Active substance: Online couples-based behavioral intervention
What this could lead to: If it works, this could provide a convenient, low-cost way for young couples to reduce risky substance use and strengthen their relationship.
What could go wrong: This is a small, early-stage trial (60 couples) testing feasibility and initial effects, so results may not be generalizable. The intervention is self-paced online, so engagement may vary.
