Welcome to the National Substance Use and Mental Health Services Survey (N‑SUMHSS) information website. The N‑SUMHSS, conducted by ICF on SAMHSA’s behalf, is an annual survey of all known active substance use and mental health treatment facilities in the United States, its territories, and the District of Columbia. This online resource center includes tools to help facilities complete the N‑SUMHSS. You’ll find useful links on the left, and practical survey tips and tutorials, below.
Your Data Matters
The N‑SUMHSS is the most comprehensive source of substance use and mental health treatment data in the country. SAMHSA, other Federal, state, and local agencies, and behavioral health care professionals use these data to understand treatment availability and identify gaps in our nation’s treatment services. The survey gathers information about the services that treatment facilities provide and summary‐level information about the clients served.
Your facility’s participation will help researchers, policy makers, and facility directors like you better understand the national treatment resource landscape, and support evidence‐based planning.
The Benefits of Participation
In addition to helping us understand substance use and mental health services in the United States, there are two reasons you should consider participating in the N‑SUMHSS:
- Your facility may be eligible to be listed on FindTreatment.gov increasing awareness of your services and helping you reach potential clients in your community. FindTreatment.gov had over 3.3 million views in 2024 and is available in English and Spanish. Your facility must complete the N‑SUMHSS every year to maintain your listing on FindTreatment.gov.
- Your facility data will be combined with other N-SUMHSS respondent data and made available on SAMHSA’s data dissemination website (https://www.samhsa.gov/data/).
