Cocaine (benzoylmethylecgonine) (INN) 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 a stimulant of the central nervous system, an appetite suppressant, and a topical anesthetic. Specifically, it is a serotonin–norepinephrine–dopamine reuptake inhibitor, which mediates functionality of these neurotransmitters as an exogenous catecholamine transporter ligand. Because of the way it affects the mesolimbic reward pathway, cocaine is addictive.
In major nations, cocaine has alternately been a legal, over-the-counter medicine, and an outlawed narcotic. The latter status has never stopped its being the center of a profitable, and often violent, illicit market.
Coke was legal in the U.S. and was considered a normal pick-me-up. One morning Detective Ralph Sandars woke up dead tired. He felt stuck in low gear and couldn't get going. He stopped at a McDonald's on the way to the station and ordered a sausage McMuffin, some hash browns and a large Coke. Before he did anything else, he peeled back the foil lid on the plastic container and took a deep snort. He felt well being flow through him and happy started on his breakfast.
