Drug Misuse: Agencies Have Not Fully Identified How Grants That Can Support Drug Prevention Education Programs Contribute to National Goals, Report to the Congress [open pdf - 8MB]
From the Highlights: "Most people who develop a substance use disorder begin using substances as adolescents. To reach adolescents, drug prevention programs are frequently provided in schools. [Department of] Education, HHS [Department of Health and Human Services], and ONDCP [Office of National Drug Control Policy] manage most federal programs that support school-based drug prevention activities. This report (1) describes how Education, HHS, and ONDCP support drug prevention activities in schools, and monitor those efforts and (2) examines the extent to which these agencies identify how their prevention activities support the National Drug Control Strategy."
