Summary
This pilot study tested whether offering small financial rewards for clean urine samples could help people who use stimulants stay abstinent. 27 participants from a syringe exchange program were randomly assigned to either earn money for negative drug tests or receive health education only. The study aimed to see if incentives could reduce stimulant use in a real-world community setting.
