Interviews with adolescent abusers and dealers reveal the proportions and depth of the problem. The legal consequences of adolescent drug abuse are examined in detail, including formal and informal processing and dispositional options within both the juvenile and adult justice systems from arrest through sentencing and appeal. Political attempts to control drug use also are outlined. The anger and pain experienced by parents when they learn their child is using drugs are discussed, and typical parental reactions -- effective and ineffective -- are examined. The role of the family in adolescent drug use and its treatment is discussed. Experts give advice to parents on how to listen actively, sensitively, and constructively to their teenagers and how to avoid problems related to overindulgence and overreaction. Descriptions of nine treatment programs, emphasizing group individual therapy and parental participation, are provided. Guidelines for the organization, implementation, and evaluation of secondary prevention programs are provided, and examples of school- and community-based programs are presented.
