Quizplus · Accepted Answer

Opiates such as heroin activate dopamine receptors, which leads to a surge of dopamine in the reward pathway of the brain. They also bind with opiate receptors, which contributes to their analgesic and numbing effects. This combination of actions gives opiates an enormous reward value to the brain, leading to their high potential for addiction.
