N-SUMHSS National Directories

The National Directory of Drug and Alcohol Abuse Treatment Facilities - 2021 is a listing of federal, state, and local government facilities and private facilities that provide substance abuse treatment services. It includes treatment facilities that (1) are licensed, certified, or otherwise approved for inclusion in the Directory by their State Substance Abuse Agencies, and (2) responded to the 2020 National Survey of Substance Abuse Treatment Services (N-SSATS). The information about each facility that appears in this Directory was provided by that facility in response to the 2020 N-SSATS. N-SSATS is conducted annually by the Substance Abuse and Mental Health Services Administration (SAMHSA).
