The Substance Abuse and Mental Health Services Administration (SAMHSA) is the agency within the U.S. Department of Health and Human Services that leads public health efforts to advance the behavioral health of the nation. SAMHSA's mission is to reduce the impact of substance abuse and mental illness on America's communities.
Congress established the Substance Abuse and Mental Health Services Administration (SAMHSA) in 1992 to make substance use and mental disorder information, services, and research more accessible.
SAMHSA works closely with other health agencies to advance behavioral health priorities.
SAMHSA Strategic Initiatives help provide treatment and services for people with mental and substance use disorders, support the families of people with mental and substance use disorders, build strong and supportive communities, prevent costly behavioral health problems, and promote better health for all Americans.
