    Welcome to the Tennessee Department of Mental Health and Substance Abuse Services

    Crisis Services

    Our network of 12 crisis services providers are located across the state. From a 24/7/365 crisis line to statewide mobile crisis, crisis walk-in centers, and crisis stabilization units, the crisis continuum serves both adults and youth.

    Mental Health

    The department administers services for people of all ages living with mental illness, co-occurring disorders, or serious emotional disturbances. Services include housing, crisis services, suicide prevention, and peer recovery.

    Substance Abuse

    The department plans, develops, administers, and evaluates a statewide system of prevention, treatment, and recovery support services for people at risk of or experiencing substance use disorder.


    The department operates four Regional Mental Health Institutes in Nashville, Memphis, Chattanooga, and Bolivar and contracts for emergency psychiatric admissions at three private hospitals in East Tennessee.
