Crack and other addictive drugs chemically alter a part of the brain called the reward system. As mentioned previously, when people smoke crack, the drug traps the chemical dopamine in the spaces between nerve cells. Dopamine creates the feelings of pleasure we get from enjoyable activities such as eating and having sex. But in crack users, dopamine keeps stimulating those cells, creating a 'high' — a euphoric feeling that lasts about 15 minutes.
