Coca
Cocaine is a naturally occurring stimulant drug found in the leaves of the coca plant, Erythroxylon coca. Although cocaine was not extracted from the coca leaf until the mid-19th century, archaeologists have discovered coca leaves at Peruvian grave sites dating from approximately 500 A.D., along with other items considered necessities for the afterlife. Thus, although current practices of cocaine use are relatively recent by historical standards, coca leaves have been chewed for at least 15 centuries. Coca leaves have been used in the past for a variety of religious, medicinal, and work-related reasons. They have also been the subject of a great deal of folklore that the leaf was of divine origin, and its use was therefore reserved as an herb provided for members of the upper classes. One Incan myth described coca as an herb provided by the god Inti to allow the Incas to endure their difficult environmental conditions without suffering from hunger or thirst. Another myth alleged that the plant grew from the remains of a beautiful woman who had been executed for adultery, cut in half, and buried. Themes of seductiveness and danger have thus been associated with cocaine for well over a millennium.
After conquering the Incas in the 16th century, the Spanish were initially opposed to cocoa use because they saw worship of the drug as a barrier to religious conversion. However, the conquistadors also recognized that the leaves energized the Indians and enabled them to work long, tedious hours in gold and silver mines with little need for food or sleep. Financial considerations overcame their religious objections, and in 1569 Philip II of Spain declared the coca leaf essential to the health of the Indian. It was not long thereafter that the Spaniards began paying the Indians with being able to treat a variety of medical disorders, including such diverse conditions as venereal diseases, headaches, asthma, rheumatism, and toothaches.

Sigmund Freud
Despite the imprimatur of the Spainards who brought coca leaves back to Europe, there was very little enthusiasm among the Europeans for coca until 1855, when a German chemist named Gaedacke was able to extract the active ingredient of the coca leaf, which he named erythroxyline. In 1859, another German, Albert Niemann, also isolated the compound and renamed it cocaine. This discovery sparked a flourish of experimentation with the compound, which peaked around the turn of the century Perhaps the most notable of the drug’s champions was Sigmund Freud, who performed a great deal of research on the drug, based both on personal experience and on the observation of others. In July 1884, Freud published his landmark paper entitled, “On Coca.” In this work, he rhapsodized about the effects of cocaine:
The psychic effect of cocaine consists of exhilaration and lasting euphoria, which does not differ in any way from the normal euphoria of a healthy person… One senses an increase of self-control and feels more vigorous and more capable of work; on the other hand, if one works, one misses the heightening of the mental powers which alcohol, tea, or coffee induces. One is simply normal, and soon finds it difficult to believe that one is under the influence of any drug at all… Long lasting intensive mental or physical work can be performed without fatigue; it is as though the need for food and sleep, which otherwise makes itself felt peremptorily at certain times of the day, were completely banished.
Freud also noted the drug’s ability to relieve the pain and thus paved the way for the discovery of cocaine as the first local anesthetic. He also claimed that cocaine might prove useful as a stimulant and as as an aphrodisiac, as well as in the treatment of depression, gastrointestinal disturbances, wasting diseases, alcoholism, morphine addiction, and asthma. None of these predictions was supported by scientific research, however, and Freud was accused of irresponsibility by much of the scientific community because of his enthusiasm for cocaine. When Freud used the drug to treat a colleague for morphine addiction, he was dismayed to find that his patient developed a similar severe dependence on cocaine. This and other developments led Freud to eventually modify his positive feelings about cocaine.
Freud was not the only person in the late 19th century to embrace this new compound. A Corsican chemist named Angelo Mariani understood the power of this newly discovered drug, and Mariani produced a mixture of coca leaves and wine, which he called “Vin Mariani.” This tonic was phenomenally successful: among those who endorsed it were kings, queens, two popes, and such notable figures as Thomas Edison, H. G. Wells, and Jules Verne. Read more…
