Question

Quizplus · Accepted Answer

Psychoactive drugs are addictive because they produce pleasurable effects when they reach the brain by activating the brain's reward circuitry. This reinforces drug-taking behavior and makes it more likely that the person will continue to use the drug. Drugs may also produce withdrawal symptoms when the drug is stopped, but this is not the only reason they are addictive. There is no evidence that humans are born with a craving for drugs. The pleasure produced by drugs is primarily experienced in the brain, not at the sense organs.
