Summary

This study tested whether a trained peer recovery specialist could help low-income, minority individuals stick with their methadone treatment for opioid use disorder. 200 participants in Baltimore were assigned to either the peer-led support program or standard care. The goal was to see if the peer approach improved treatment retention and adherence over six months.
