Both of these substances are illegal. I don't believe that doing drugs is a criminal issue however I do no it is not a wise decision to use crack or cocaine. Cocaine is a white powder that can come compressed to appear as a rock. Crack is cocaine cooked to change the chemical structure. Crack is smoked and cocaine is usually snorted. Both substances can cause paranora and a feeling of having to have just a litle more. They also depleat chemicals in your brain that just maintain you feeling normal. After abusing cocaine, these chemicals are depleted and a true clinical depression is inevitalbe. You will always feel an impending doom after the cocaine is gone. The cocaine cycle is an extremely diffucult one to stop once one has a taste of the " devil's dandruff'. No one is better off a user or can say they truely feel better that they use. You cant avoid the down side.
The powder can be made into the rock.Dont touch it.
