This course introduces the biological mechanisms of substance use and misuse (e.g., nervous system activity, tolerance, withdrawal, and metabolism) and the resulting behavioral and health consequences. Students will also examine the classification of various substances, epidemiological data and trends, the diagnoses and diagnostic criteria of substance use disorders, genetic and biological influences on addiction, and biological theories of addiction. Other potential topics include behavioral addictions (e.g., gambling, eating, video games, or sex) and the effects of drugs on individuals, families, and society.
