Module 2 readings introduce several key terms with their meaning and use defined. This initial section concludes with an explanation of the biopsychosocial perspective on substance misuse and how the various types of theories we are studying might fit together rather than “compete” with each other to help shape our understanding. This biopsychosocial perspective forms the structure for our course Part 1 analysis of theories. Chapter 2 of our Module 2 readings examines the major diagnostic systems used in the U.S. and internationally for diagnosing various types and severity of substance use disorder (SUD). In Chapter 3, we explore several trending topics in the substance use/misuse and SUD arena.
