Summary

This study tests whether a mobile phone app that tracks drug use and gives feedback can help people reduce risky drug use over 12 months. About 458 adults from community health centers in Southern California are taking part. They are split into three groups: one gets the mobile app plus brief counseling, one gets only brief counseling, and one gets usual care. The goal is to see if the app makes the counseling more effective and lasting.

What this could mean

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

Active substance: mobile phone self-monitoring and feedback (behavioral intervention)
What this could lead to: If successful, this could provide a scalable, low-cost way to help people reduce risky drug use and improve health outcomes in primary care.
What could go wrong: This is a behavioral intervention study, not a drug trial, so results depend on participant engagement. The effects may be modest and not generalize to all populations.
