Freud and cocaine
Freud was an early user and proponent of cocaine as a stimulant as well as analgesic. He wrote several articles on the antidepressant qualities of the drug and he was influenced by his friend and confidant Wilhelm Fliess, who recommended cocaine for the treatment of the "nasal reflex neurosis." Fliess operated on Freud and a number of Freud's patients whom he believed to be suffering from the disorder, including Emma Eckstein, whose surgery proved disastrous.
