Which drug did Sigmund Freud write about and reportedly abuse?

• A. Amphetamine
• B. Methamphetamine
• C. Cocaine
• D. Heroin

Answer: (C)

Freud is historically linked to cocaine: he wrote an influential piece promoting its medical uses and even used cocaine himself during his early career. He described effects like increased energy and mood betterment and suggested it could help with various conditions. This direct writing about cocaine and his personal experimentation with it are the reasons cocaine is the best answer. The other drugs aren’t tied to Freud’s writings or personal use—amphetamines and methamphetamines came into prominence later, and heroin was not part of his documented work.
