What are the general effects of crack?

Answer 1

Crack increases the release of dopamine in the brain. Although this feels good while high, regular use can deplete dopamine and cause depression; in worst case senarios, psychosis. Crack also increases heart rate, blood pressure, paranoia, anxiety, and impulsiveness. If a person smokes the drug, they have an extremely high risk of tooth decay, snorting the drug can result in a deviated septum, and slamming the drug can collapse veins and cause extreme soreness and bruising.
