Cash for clean tests: can rewards boost opioid recovery?
NCT ID NCT05288751
First seen Jun 26, 2026 · Last updated Sep 17, 2026 · Updated 2 times
Summary
This study tests whether offering small monetary rewards can help people with opioid and stimulant use disorders stay in treatment and avoid drug use. Fifty-six adults starting medication for opioid use disorder at a family medicine clinic will earn incentives for attending appointments and providing drug-free urine samples. The goal is to see if this approach works in a primary care setting, not just specialized clinics.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Contingency management (behavioral intervention using monetary incentives)
- What this could lead to
- If it works, this approach could make it easier for people to stick with addiction treatment in a regular doctor's office, improving recovery rates.
- What could go wrong
- This is a small pilot study with only 56 participants, so results may not apply to everyone. The rewards are small and may not be enough to change behavior long-term.
