Across the United States, schools and communities have found ways to turn the tide in the battle against drugs. This guidebook describes the methods they have used and the actions they have taken. The first section, "Children and Drugs" outlines the nature and extent of the drug problem and summarizes the latest research on the effects of drugs on students and schools. The next section describes action strategies for parents, schools, students, and communities to combat student drug use most effectively. The recommendations are derived from research and from the experiences of schools throughout the country. Special sections which follow are "Teaching About Drug Prevention,""How the Law Can Help," and a resource section on specific drugs and their effects, sources of information for further reading, and a list of 87 references used in creating this guidebook.
