The key concepts that guide the handbook's recommendations are youth participation in the development of programs, the involvement of youth in communicating drug-prevention messages to their peers, and the development of localized programs that are sensitive to the culture and traditions of groups targeted for prevention measures. By using the information presented in this handbook, youth and adults can cooperate in starting, sustaining, and evaluating a juvenile drug abuse prevention program. Instruction is provided on how to collect information about drug problems in the community, how to build partnerships with key sections of the community, and what tools will be most useful in implementing programs under various types of conditions and circumstances. General information is provided on drugs, drug use, and existing program approaches and drug-prevention techniques. Suggestions and samples are provided for workshops, checklists, and format grids that can be used as aids for collecting information.
