Dopamine Levels Increase. All addictive drugs affect brain pathways involving rewardâthat is, the dopamine system in the reward pathway. Within seconds to minutes of entering the body, drugs cause dramatic changes to synapses in the brain. By activating the brain's reward circuitry, drugs deliver a jolt of intense pleasure.
Why are some drugs addictive? Scientists think that all addictive drugs activate the brain's 'reward system', by increasing the release of the chemical dopamine from neurons in key areas of the brain. Dopamine release occurs after pleasurable experiences, for example after food or sex, but can also be induced by some drugs. Drugs that artificially increase dopamine release in this way may cause craving for more.
