As part of the announced 2025 HHS reorganization, SAMHSA is planned to be integrated into the new Administration for a Healthy America. SAMHSA was established in 1992 by Congress as part of a reorganization stemming from the abolition of Alcohol, Drug Abuse, and Mental Health Administration (ADAMHA). ADAMHA had been established in 1973, combining the National Institute on Alcohol Abuse and Alcoholism (NIAAA), National Institute on Drug Abuse (NIDA), National Institute of Mental Health (NIMH).

NIMH, NIAAA, and NIDA continued with their research functions as agencies within the National Institutes of Health. More information...
