The first section of the book, Background and Diagnostic Issues, deals with epidemiology, ethnic and cultural factors, and assessment of substance abuse among individuals with chronic mental illnesses. The second section of the book, Treatment, deals with more practical issues. "Treatment of Substance Use Disorders and Schizophrenia," by Kate Bergman Carey, and "Dual Diagnosis in the Elderly," by Steven Bartels and Joseph Liberto, are particularly helpful. The third section, Social System Issues, includes the chapter " ‘Double Jeopardy’: Some Legal Issues Affecting Persons With Dual Diagnoses," by Laura M. Champlain and Stanley S. Herr, which contains useful information that is hard to find elsewhere.
