The Community Mental Health Services Block Grant Program and Substance Abuse Prevention and Treatment Block Grant Program will disperse $1.5 billion each to states and territories, with the latter also awarding money to a tribe. This follows the March announcement of supplemental funding of nearly $2.5 billion for these programs. The Substance Abuse and Mental Health Services Administration, an operating division of HHS, has expedited federal funding to grantees to help communities grappling with mental health and substance use needs during the COVID-19 pandemic.
