Psychoactive Drugs: • Affect the mind and mental process Illegal Drugs
The “Reward Pathway” • Psychoactive drugs typically create a pleasurable feeling that the user wants to repeat. • Many psychoactive drugs trigger activity along a pathway of cells in the brain called the “reward pathway” • Cells release a chemical called dopamine. • Extra dopamine released during drug use can cause the user to ignore the harmful effects of the drug and want to continue using it. • Flooding the “reward pathway” with dopamine may lead to intense cravings for drug. • After time, drug abuse can dull the brain’s reactions to natural levels of dopamine. The user no longer feels pleasure from normal activities. Drug Abuse and the Brain *
