Cocaine
Cocaine is a powerful central nervous system stimulant that affects your alertness, feel the need for sleep, and provides intense feelings of pleasure. Cocaine is prepared from a loaf of coca bush, which grows in Peru. Albert Niemann, a German chemist, first identified cocaine in the mid-19th century. It was introduced as a medicine to treat many illnesses. Later, it was used in surgery. In some places cocaine is still used for surgery, yet in many places they are currently using lidocaine.
In the 1880s Sigmund Freud created a sensation with a series of papers praising cocaines potential to cure depression, alcoholism, and morphine addiction. This excitement was soon replaced when documented reports began to circulate of fatal cocaine poisoning and cocaine addiction.
