Cocaine comes from the leaves of the tropical coca plant.
It can be injected and, in some forms smoked. Injecting the drug produces a powerful, fast response that peaks in minutes and disappears within an hour. Freebase and crack are both smokable forms of cocaine and carry a kick similar to injecting the drug. Freebase gives an intense high lasting 2 to 5 minutes, which quickly fades into a restless desire for more of the drug. Basically, cocaine overworks your body and brain.
