Cocaine
As a medical researcher, 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' noses whom he believed to be suffering from the disorder, including Emma Eckstein, whose surgery proved disastrous.[34]
Freud felt that cocaine would work as a panacea for many disorders and wrote a well-received paper, "On Coca", explaining its virtues. He prescribed it to his friend Ernst von Fleischl-Marxow to help him overcome a morphine addiction he had acquired while treating a disease of the nervous system.[35] Freud also recommended it to many of his close family and friends. He narrowly missed out on obtaining scientific priority for discovering cocaine's anesthetic properties (of which Freud was aware but on which he had not written extensively), after Karl Koller, a colleague of Freud's in Vienna, presented a report to a medical society in 1884 outlining the ways cocaine could be used for delicate eye surgery. Freud was bruised by this, especially because this would turn out to be one of the few safe uses of cocaine, as reports of addiction and overdose began to filter in from many places in the world. Freud's medical reputation became somewhat tarnished because of this early ambition. Furthermore, Freud's friend Fleischl-Marxow developed an acute case of "cocaine psychosis" as a result of Freud's prescriptions and died a few years later. Freud felt great regret over these events, which later biographers have dubbed "The Cocaine Incident".[citation needed] However, he managed to move on, and some speculate that he even continued to use cocaine after this event. Jürgen von Scheidt posits that most of Freud's psychoanalytical theory was a byproduct of his cocaine use.[36]
In _The Origins of Psycho-Analysis: Letters to Wilhelm Fliess, 1887-1902_
(by Sigmund Freud, edited and authorized by a large number of people,
published by Imago Publishing Company, London, 1954), p4-6, I find
this information: Fliess trained as a nose-and-mouth specialist.
He discovered a syndrome, which he dubbed the nasal reflex neurosis,
typified by many and varied symptoms, all over the body; what they had in
common was that they could all be brought "temporarily to an end by
anaesthetizing with cocaine the responsible area in the nose". He
subsequently observed that "neuroses with a sexual aetiology" often
assumed the form of nasal reflex neurosis, and was led to assume a
"special connection" between the nose and the genitalia, particularly
the female genitalia, it seems. In this regard he remarks on the
phenomenon of the "vicarious nosebleed in place of menstruation"...
All of this was apparently detailed in an 1897 opus.
