#10 Sigmund Freud: Cocaine

The father of psychoanalysis was also an avid cocaine fan. Freud used cocaine to treat a morphine-addicted friend only to slowly kill him with it over a seven-year period. But Freud was determined in his conviction of cocaine as a miracle healing drug. As Howard Markel writes: “Yet like most humans ensnared by cocaine’s addictive grip, for the next 12 years, [Freud] continued to sing its praises and consumed a great deal of cocaine to quell his physical aches and mental anxieties. In a perverse way, Freud loved how cocaine made him talk endlessly about memories and experiences he previously thought were locked in his brain for no one to hear, let alone judge.”
