This is a National Survey of Substance Abuse Treatment Services (N-SSATS) annual report that includes the National Directory of Drug and Alcohol Abuse Treatment Programs in 2013. The National Directory of Drug and Alcohol Abuse Treatment Program 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 2012 National Survey of Substance Abuse Treatment Services (N-SSATS). N-SSATS is designed to collect data on the location, characteristics, and use of alcohol and drug abuse treatment facilities and services throughout the 50 States, the District of Columbia, and other U.S. jurisdictions.
