SAMHSA notes that the list includes practitioners who previously held a DATA-2000 waiver, that the waiver requirement has since been eliminated through the Consolidated Appropriations Act, 2023, and that the list is not inclusive of all practitioners able to prescribe buprenorphine. SAMHSA also notes that the list only includes practitioners who consented to release their practice information.
