Amphetamines and cocaine are stimulants that increase the levels of dopamine in the brain's reward center. Opiates, such as heroin and morphine, also activate the reward center by increasing the release of endorphins, which are natural pain-relieving chemicals that produce a sense of euphoria. Therefore, all of these drugs directly stimulate the internal reward center or pleasure pathways in the brain.
