Summary

This study tests whether an app that gives financial rewards for drug-negative saliva tests works for older adults with opioid, cocaine, or methamphetamine use disorder. Researchers will compare results between older and younger participants to see if age affects how well the app works. The goal is to find out if app-based incentives can help people stay drug-free.

What this could mean

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

Active substance: DynamiCare app with financial incentives for drug-negative saliva tests
What this could lead to: If successful, this could show that app-based rewards help older adults stay drug-free, offering a scalable tool for addiction treatment.
What could go wrong: This is a small, early-stage study with only 175 participants, and the sham control group gets no incentives, so results may not apply broadly. The app requires a smartphone and data plan, which may limit participation.
