Introduction to the Field and the Issues
This volume provides a comprehensive overview of the origins, development, and course of substance use as it emerges and unfolds in adolescence, a period where great change at genetic, neurobiological, behavioral, and social-environmental levels is taking place. The volume also provides reviews of clinical symptomatology and the multiple methods for intervention that have developed to address this major set of public health problems. This chapter provides a brief overview of these areas; it includes sections on epidemiology, similarities and differences among the different drugs of abuse, etiology and course, clinical symptomatology and comorbidity, intervention methods, and social policy. These summaries, covering multiple levels of analysis, provide a comprehensive description of a field that is still developing, but that has already achieved a substantial level of maturity.
