Biological, psychological and social factors are considered in this volume in its exploration of adolescent substance abuse, with adolescents presented as a clearly defined group with unique needs and concerns. The author examines issues such as assessment, treatment planning, service provision and the recovery process, and proposes creative treatment approaches. Integrating the complex elements which impact upon the initiation, maintenance and treatment of young substance abusers, the author uses his biopsychosocial model to examine normative issues for adolescents and how impairment in these areas can cause - or be the result of - substance abuse. Consideration is also given to particularly vulnerable young people, such as those with concurrent psychological disorders or who are victims of child abuse, and who subsequently require additional therapeutic understanding and skill.
