What is SAMHSA?

The Substance Abuse and Mental Health Services Administration (SAMHSA) is a federal agency within the U.S. Department of Health and Human Services. SAMHSA’s core mission is to improve public health through the advancement of behavioral health, supporting mental health and substance abuse recovery across the United States. Through SAMHSA grants and funding opportunities, organizations and government agencies can address key challenges in mental health and substance use. These grants are a vital resource for communities seeking to expand access to behavioral health services, reduce the impact of addiction, and improve mental wellness.
