This document describes the Glendale Unified School District's (California) comprehensive drug, alcohol, and tobacco education program. The program is based on three components: (1) a sequential outcome-based curriculum that provides students with knowledge about substance abuse and peer-resistant skills; (2) a strong message that the possession, use, and sale of these substances will not be tolerated on the campus or at school-sponsored activities; and (3) community involvement to coordinate resources for prevention and rehabilitation. The following components are briefly described--planning, policy, curriculum for different grade levels, staff development, parent and community involvement, student assistance and intervention, positive alternatives, and evaluation. Student and teacher surveys and analyses of school discipline and police records indicate a decline in drug use, improved knowledge and use of communication and peer-resistant skills, a decline in school suspensions, and a decrease in juvenile felonies and misdemeanors. (Contains five curriculum references.) (LMI)
