National Substance Use and Mental Health Services Survey

The N-SUMHSS provides federal, state, and local governments, as well as the behavioral health research community, with information about the number and characteristics of public and private substance use and mental health treatment facilities nationwide. This annual survey is crucial as the data gathered is the information on SAMHSA’s FindTreatment.gov website, our nation’s most comprehensive national source of data on substance use and mental health treatment facilities.The N-SUMHSS replaced the National Survey of Substance Abuse Treatment Services (N-SSATS) and the National Mental Health Services Survey (N-MHSS) in 2021 by combining questions for substance use and mental health facilities. The N-SSATS and N-MHSS were combined to reduce burden on the facilities, optimize government resources to collect data, and enhance the quality of data collected.
