This report presents results from the 2017 National Survey of Substance Abuse Treatment Services (N-SSATS), an annual census of facilities providing substance abuse treatment. Conducted by the Substance Abuse and Mental Health Services Administration (SAMHSA), 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 jurisdictions. It is important to note that values in charts, narrative lists, and percentage distributions are calculated using actual raw numbers and rounded for presentation in this report; calculations using rounded values may produce different results.
