Measure
Video-based DOT Application
Video-based directly observed therapy (DOT) Application: Participants will be asked to record daily videos of themselves confirming daily ingestion of their buprenorphine. Clinical staff (i.e. physicians, nurses and medical assistants) of patients enrolled in the intervention group will be given training and the opportunity to review medication taking videos.
Treatment as Usual (TAU)
Treatment-as-usual administered at office-based buprenorphine treatment clinics.
