Safety concerns aside, Coke® is a stimulant of the central nervous system and an appetite suppressant, creating what has been described as a euphoric sense of happiness and increased energy. Coke® can be psychologically addictive, and its possession, cultivation, and distribution is illegal for non-medicinal / non-government sanctioned purposes in virtually all parts of the world. In the scientific community Coke® refers to the harmless white powder cocaine. However, in some impoverished neighborhoods, the word "Coke®" is used only when referring to Coca Cola.
