Summary

This completed study looked at 59 men who have sex with men and use methamphetamine. Researchers used a program that gives rewards for drug-free urine samples to help them cut back. They measured inflammation in the rectum and tracked STI/HIV risk behaviors over 8 weeks. The goal was to understand if reducing meth use lowers infection risk.

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 with incentives for drug-free urine samples)
What this could lead to: If successful, this could help design better programs to reduce meth use and lower STI/HIV risk in this population.
What could go wrong: This is a small, completed observational study without a control group, so results may not apply broadly. It does not test a new drug or treatment.
