The Ewing Marion Kauffman Foundation began surveying Kansas City area teens during the 1984-85 school year. The Kauffman Teen Survey now addresses two sets of issues for teens. Teen Health Behaviors, addressed in this report, have been a focus of the survey since its inception. The report focuses on teen use of alcohol, tobacco, and other drugs in the 2000-01 academic year. This report provides current and historical information about the usage rates of alcohol, tobacco, marijuana, and other substances, as reported by teenagers who attend greater Kansas City are public schools. Students in 8th-, 10th-, and 12th- grade are asked to complete surveys to report how often they use a variety of drugs. It is encouraging to note that a number of decreases in the usage rates of specific substances appeared between the academic years 1999-2000 and 2000-01, and that both the number and size of increases in usage rates were low overall.
