Social circles as medicine: tanzania study tests peer support for opioid recovery
NCT ID NCT04479475
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a program that brings in family and friends to support people receiving methadone treatment for opioid use disorder in Tanzania. The goal was to see if this social support approach is acceptable and practical, and whether it helps people stick to their methadone and HIV medications. 58 people took part, including those on methadone and their chosen supporters. The study did not aim to cure addiction or HIV, but to learn if involving loved ones improves treatment adherence.
