Cocaine [SEP] Discovery
For over a thousand years South American indigenous peoples have chewed the leaves of "Erythroxylon coca", a plant that contains vital nutrients as well as numerous alkaloids, including cocaine. The coca leaf was, and still is, chewed almost universally by some indigenous communities. The remains of coca leaves have been found with ancient Peruvian mummies, and pottery from the time period depicts humans with bulged cheeks, indicating the presence of something on which they are chewing. There is also evidence that these cultures used a mixture of coca leaves and saliva as an anesthetic for the performance of trepanation. When the Spanish arrived in South America, most at first ignored aboriginal claims that the leaf gave them strength and energy, and declared the practice of chewing it the work of the Devil.
