In 1875, opium dens were outlawed in which city?

• A. New York
• B. Los Angeles
• C. San Francisco
• D. Chicago

Answer: (C)

Opium dens were a focus of late 19th-century anti-vice campaigns, and San Francisco took a decisive step in 1875 by enacting a municipal ordinance that made operating opium dens illegal and criminalized non-medical opium use. This specific year-and-city combination is well documented, so the crackdown is most closely associated with San Francisco. Other cities regulated opium dens as well, but not with the same widely cited 1875 ban.
