This study proposes to collect pilot data that will inform a future grant application. We propose to complete interviews (60 min) on 25 individuals who are currently or have previously used opioids and are either currently on MAT or chose to not begin MAT. Semi-structured interviews will identify (1) what individual and treatment factors helped participants initiate MAT or, conversely, inhibited engagement in MAT, (2) what concerns they had about starting MAT, and (3) encouraging them to reflect on what additional information could have helped them initiate MAT sooner. Eligible participants will be compensated $20 for their participation in the study.
