Cocaine is a crystalline tropane alkaloid that is obtained from the leaves of the coca plant. The name comes from "coca"in addition to the alkaloid suffix -ine, forming cocaine. It is both a stimulant of the central nervous system and an appetite suppressant. Specifically, it is a dopamine reuptake inhibitor, a norepinephrine reuptake inhibitor and a serotonin reuptake inhibitor. Because of the way it affects the mesolimbic reward pathway, cocaine is addictive.
Nevertheless, cocaine is used in medicine as a topical anesthetic, even in
children, specifically in eye, nose and throat surgery.Cocaine in its purest form is a white, pearly product. Cocaine appearing in powder form is a salt, typically cocaine hydrochloride. Street market cocaine is frequently adulterated or “cut” with various powdery fillers to increase its weight; the substances most commonly used in this process are baking soda; sugars, such as lactose, dextrose, inositol,and mannitol; and local anesthetics, such as lidocaine or benzocaine, which mimic or add to cocaine's numbing effect on mucous membranes. Cocaine may also be "cut" with other stimulants such as methamphetamine.Adulteratedcocaine is often a white, off-white or pinkish powder.
