Administered by the Office of National Drug Control Policy (ONDCP), in partnership with the Substance Abuse and Mental Health Services Administration (SAMHSA), the Drug Free Communities Support Program (DFC) is a federal grant program that provides funding to community-based coalitions that organize to prevent youth substance use. Since the passage of the "DFC Act in 1997," the DFC program has funded nearly 2,000 coalitions and currently mobilizes nearly 9,000 community volunteers across the country. This paper describes the findings of the "Drug Free Communities Support Program National Evaluation 2011 Interim Findings Report" (2012), which is based on DFC national evaluation data on alcohol, tobacco, and marijuana use that DFC grantees report every two years. Lessons learned from colleges and universities that adopted DFC programs are presented.
