  Cocaine - Wikipedia, the free encyclopedia
Cocaine is a crystalline tropane alkaloid that is obtained from the leaves of the coca plant.
Cocaine hydrochloride is not well-suited for smoking because the temperature at which it vaporizes is very high, and close to the temperature at which it burns; however, cocaine base vaporizes at a low temperature, which makes it suitable for inhalation.
Cocaine's primary acute effect on brain chemistry is to raise the amount of dopamine and serotonin in the nucleus accumbens (the pleasure center in the brain); this effect ceases, due to metabolism of cocaine to inactive compounds and particularly due to the depletion of the transmitter resources (tachyphylaxis).
