Cocaine is a purified extract from the leaves of the Erythroxylum coca bush. This plant grows in the Andes region of South America. Different chemical processes produce the two main forms of cocaine. Powdered cocaine commonly known on the street as "coke" or "blow" dissolves in water. Users can snort or inject powdered cocaine. Crack cocaine commonly known on the street as "crack" or "rock" is made by a chemical process that leaves it in its "freebase" form, which can be smoked. About 14% of U.S. adults have tried cocaine. One in 40 adults has used it in the past year. Young men aged 18 to 25 are the biggest cocaine users, with 8% using it in the previous 12 months (Holstege, 2011) . Anatomy & Physiological Effects of a Cocaine High Smoking or injecting cocaine results in nearly instantaneous effects. Rapid absorption through nasal tissues makes snorting cocaine nearly as fast-acting. Whatever the method of taking it in, cocaine quickly enters the bloodstream and travels to the brain. Deep in the brain, cocaine interferes with the chemical messenger’s neurotransmitters that nerves use to communicate with each other. Cocaine blocks nor epinephrine, serotonin, dopamine, and other neurotransmitters from being reabsorbed. The resulting chemical buildup between nerves causes euphoria or feeling "high." Cocaine's immediate effects wear off in 30 minutes to two hours. Smoking or injecting cocaine results in a faster and shorter high, compared to snorting coke. Cocaine is responsible for more U.S. emergency room visits than any other illegal drug. Cocaine harms the brain, heart, blood vessels, and lungs and can even cause sudden death (Holstege, 2011).
