Naaa, crack cocaine is essentially a form of free base coke. Powdered coke that you snort is in the form of a sodium salt. It cannot be smoked as it will just decompose to CO2 and water. Crack is made by taking the sodium salt of cocaine and removing the sodium cation from the cocaine molecule. This is usually done be dissolving the powder cocaine in a weak sodium carbonate solution heating and adding a small amount of ammonium. The free based cocaine then precipitates out of solution and when stirred will form a clump that looks like "a crack of soap" and thus the name. The free based version of cocaine, when smoked, doesn't decompose but volatilizes into a cocaine vapor that when inhaled almost instantaneously passes through the alveoli of the lungs and into the blood stream having an almost instantaneous impact on the brain which dumps a large concentration of dopamine into the brain causing an incredible, but short lived, euphoric feeling. Which explaines crack/freebase cocaines addictiviness. Only nicotene is more addictive and deadly.
