Explanation: The lectures present 19th-century drug regulation as driven by a combination of (1) moral/religious reform movements, (2) capitalist/productivity and labor-discipline concerns, and (3) racialized/ethnicized fears linking drugs to “foreign” populations and migration—so A–C operate together. (Lecture/Reading: Breen, The Age of Intoxication; reinforced in Wright, Not Just a “Place for the Smoking of Opium” and Ram, Hashishophobia.)
