Powder cocaine is a hydrochloride salt derived from processed extracts of the leaves of the coca plant. "Crack" is a type of processed cocaine that is formed into a rock-like crystal, freebased cocaine.

Cocaine is a powerful stimulant, which means it might keep you wired, but it comes not without a risk. Cocaine causes your blood vessels to constrict immediately, increasing your heart rate, blood pressure and body temperature. At first, this may make you sweaty and shaky, but seizures, cardiac arrest and even death are real risks. The risk of sudden death is even greater when cocaine is combined with alcohol.

Cocaine overstimulates your brain’s natural reward system. While this may result in the drug’s pleasurable effects, over time it can actually change the way your brain works, teaching you to repeat the behavior making it highly addictive. And smoking it, in the form of “crack,” increases the risk of addiction because it gets into your brain even faster. Binging is taking the drug repeatedly and at higher doses in a short period of time which can lead to irritability and anxiety.

Prolonged cocaine snorting can irritate and cause scabs to form on your mucus membranes, damage your nasal septum (the thin wall that separates your left and right nostrils) and eventually make your nose collapse.
