" In 2015, approximately 2.2 million adolescents aged 12 to17 were current users of illicit drugs. The Drug-Free Communities Act of 1997 established the DFC Support Program-a federal grant program supporting drug abuse prevention efforts that engage schools, law enforcement, and other sectors of a community. The program targets reductions in the use of alcohol, tobacco, marijuana, and the illicit use of prescription drugs. The Office of National Drug Control Policy Reauthorization Act of 2006 includes a provision that GAO routinely assess ONDCP's programs and operations. This report addresses: (1) the extent to which ONDCP and SAMHSA use leading practices to coordinate program administration and the types of activities funded; and (2) the extent to which ONDCP's and SAMHSA's' operating procedures both ensure DFC grantees comply with governing statutes and provide a basis for performance monitoring. To conduct this work, GAO analyzed agency policies from 2013-2015 (most recent available); interviewed agency officials; and analyzed coordination efforts against relevant key practices GAO identified previously. GAO reviewed files obtained from a non-generalizable random sample of 30 grantees and interviewed a random subset of 10. "
