NCT ID NCT06406296
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a group therapy called Acceptance and Commitment Therapy (ACT) for people struggling with problematic chemsex—using drugs to enhance or manage sex. 36 adults who reported high levels of hypersexuality and drug use took part. The therapy focused on values, mindfulness, and committed action to reduce harmful behaviors and distress.

- What this could lead to
- If it works, this could point toward a psychological treatment to help people reduce problematic chemsex and related distress.
- What could go wrong
- This is a small, completed trial with only 36 participants, so results may not apply to everyone. The therapy is behavioral, not a medical cure, and success depends on individual engagement.
