Tobacco, alcohol, and other drug use among high school students--United States, 1991.

In the United States, use of tobacco, alcohol, and other drugs is associated with the leading causes of morbidity and mortality (e.g., motor-vehicle crashes, homicide, suicide, and cancer [1]), with lower educational achievement, and with school dropout (2-5). This report presents self-reported data about the prevalence of tobacco, alcohol, marijuana, and cocaine use among students in grades 9-12 from two school-based components of the Youth Risk Behavior Surveillance System (6): 1) state and local Youth Risk Behavior Surveys (YRBSs) conducted by departments of education in 23 states and 10 cities during the spring of 1991 and 2) the national YRBS conducted during the same period.
