Q.) How does crack work?

A.) Crack works on the automatic nervous system. The automatic nervous system controls the sympathetic system which speeds everything up such as the heart and breathing. The autonomic nervous system also controls the para-sympathetic system which does the exact opposite (slows things down). This is why when people smoke the crack they get hyper. Crack works by one of the brains neuro transmitters releasing all the dopamine at once (dopamine is a chemical in the brain which releases feelings of pleasure. When we laugh a slight amount of dopamine is released and this makes you feel good). After this dopamine has been released, Crack can, in some cases, block the re-uptake of the dopamine. If this happens the person will now find it a mission to get any sort of pleasure.
