Quizplus · Accepted Answer

An agonist drug binds to receptor sites and mimics the function of an illicit drug, thereby producing a similar effect as that drug. It does not produce the high of the illicit drug but instead activates the receptor to produce a response. This can be useful in addiction treatment by reducing cravings and withdrawal symptoms. Aversive drugs make the effect of the illicit drug less desirable, while antagonists block the effect of the illicit drug. Appetitive drugs increase desire but are not relevant in this context.
