In 1984 the Newberg (Oregon) School District began its Impact Program for limiting substance abuse. The program's primary purposes are to raise awareness, disseminate information, intervene when chemicals seem to be hampering success in school, refer users to treatment centers, and provide support for those returning after treatment. This report's first chapter describes the program's origin in training provided by a Portland (Oregon) hospital. Based on the premise that addiction is a treatable disease that follows a predictable pattern, the training was first offered to teachers, counselors, administrators, board members, police liaison officers, parents, and church leaders. These trainees then provided workshops and inservice programs for others. Once trained, the team members intervene in the lives of students suspected of drug abuse. Chapter 2 describes how substance abusers are identified, referred for treatment, treated, and returned to school. The third chapter describes the objectives of the Impact Program's substance abuse prevention component and its place in the district curriculum. The fourth chapter explains community involvement in the program. Appendices provide the student referral form used, a scope and sequence chart for substance abuse prevention curricula from kindergarten through the fifth grade, and a 1986 flyer describing the program.
