The Office of National Drug Control Policy (ONDCP) currently is implementing the National Youth Anti-Drug Media Campaign to "educate and enable America's youth to reject illegal drugs as well as alcohol and tobacco." Preceded by test phases of limited scope and impact, the fully integrated media campaign started in mid-1999, and ONDCP expects to see improvement in anti-drug attitudes that will lead to decreases in youth drug use by mid-2002. This report responds to the directive for ONDCP to provide information on recent youth drug use trends, specifically the Youth Risk Behavior survey, and their relation to the National Youth Anti-Drug media Campaign. ONDCP's response focuses on the following topics, each of which is discussed in separate sections of the report: how the government tracks youth drug use; trends in youth drug use; different perspectives on the same problem; the National Youth Anti-Drug Media Campaign; and evaluating youth drug use and the media campaign. Appendixes provide the Youth Risk Behavior Survey summary; comparison of surveys; glossary of acronyms; and chart data tables. (Contains 26 references.) (MKA)
