The U.S. Congress appropriated $25 million in fiscal year (FY) 1998 in order to establish the Combating Underage Drinking Program, along with another $25 million in FY 1999 in order to continue it under the title of the Enforcing the Underage Drinking Laws Program. The Office of Juvenile Justice and Delinquency Prevention (OJJDP) administers the program and assists States and other jurisdictions in their efforts to keep youth from drinking alcoholic beverages and engaging in associated drinking and driving. This compendium first presents an overview of the extent of the problem of underage drinking and highlights national statistics on its impact, prevalence, trends, relationship to driving, and other repeated information. This section includes examples of approaches and initiatives to counter underage drinking; and it also describes OJJDP's role in the Underage Drinking Laws program, other OJJDP-related initiatives, and contact information for further assistance. This is followed by a resources section that contains contact information for Federal, State, and local agencies as well as national and private organizations. It describes some of their current initiatives, programs, strategies, and related materials that address underage drinking. Lists of State substance abuse agencies and governors' highway safety representatives and coordinators are included as well. A selected annotated bibliography contains a listing of books and journal articles that constitute a sampling of various aspects of the topic, including research, policy, and intervention.
