What schools can do and are doing to prevent the abuse of drugs by their students is the focus of this report. The first section of the report "An Overview of Current Efforts" presents the findings of a one-year study of drug education in the United States, with a subjective analysis of the various approaches in the field. In the second section "Guide for the Drug Education Planner," specific guidelines for planning, implementing, and evaluating local drug education efforts are offered. "Case Studies," section three, presents detailed descriptions of 10 different approaches in the following locations: Coronado, California; State of Oregon; Duluth, Minnesota; Milwaukee, Wisconsin; Wayne County, Michigan; Seymour, Connecticut; Dade County, Florida; Maricopa County, Arizona; Parkway, Missouri; and Laredo, Texas. Six commercially developed programs are described in section four "Product Reports"; these are The Creative Learning Group Drug Education Program (K-Grade 9); Drug Education Program or Drug Abuse Decision System (DADs) (Grades 9-12); The Drug Experience: Data for Decisionmaking (Grades 7 and 8, but also used in Grades 6-12); Drugs: Insights and Illusions (Junior and Senior High School Students); Technicon Drug Decision Program (Grades 6-9); and Impact Plus Two and Why? (Grades 5 and 6 and Grades 7 and 8). A "Teacher's Guide to Resources in Drug Education" provides reviews, catalogs, resource handbooks, and compiled bibliographies on instructional aids and materials, curriculum ideas, and background information on drug education. Current ERIC entries on Drug Education Programs are listed, as are past PREP reports. (Author/DB)
