Summary

This study is gathering information from men who have sex with men who take part in chemsex (using drugs before or during sex) in Bangkok, Thailand. Researchers will survey party hosts and guests about their drug use, sexual health, mental health, and experiences of stigma. The goal is to understand their needs and design a harm reduction program led by the community.

What this could mean

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

What this could lead to
If successful, this could lead to a community-driven harm reduction program that reduces substance use and sexual health risks among men who have sex with men in Bangkok.
What could go wrong
This is a small, early-stage study (76 participants) focused on gathering information, not testing a treatment. The findings may not apply to other cities or populations.
