Adolescent drug abuse is one of the most challenging disorders to treat. It impacts on schools, community-based programs, mental health and medical facilities, and juvenile justice settings. This book provides practitioners, program developers and policy makers with the most up-to-date and practical information for improving outcomes in adolescent substance abuse. The authors cover a range of issues, including empirically-based treatment development protocols; research advances; interventions with special populations; culturally based intervention guidelines, and recommendations for practice and policy.
