Cocaine (also known as coke, crack or blow) is an illegal stimulant drug that speeds up the workings of the brain. Today, cocaine is a Schedule II drug, meaning that it has high potential for abuse but can be used by a doctor for medical uses. It is found and harvested off the leaves of a coca plant. Cocaine can be found in many forms including a salty form, a crack form or even a freebase(normal) form.
