This paper and community guide is based on the recommendations of a panel of nongovernmental experts who systematically reviewed the current research on the family's role in reducing substance abuse among youth. This booklet answers questions such as: (1) "Why focus on families?"; (2) "How big is the problem? What are the facts?"; (3) "What puts children at risk for substance abuse?"; (5) "What protects children from substance abuse?"; (6) "How do we know what works?" It provides lists of "What you can do!" for parents and community members. The recommendations are intended to enhance local efforts to reduce substance abuse by minors. (EMK)
