What drug blocks receptors and causes a feeling of intense pleasure

There are two drugs that block receptors and cause a feeling of intense pleasure and they are heroine and cocaine. They both help block anything that isn't the dopamine and cause the feeling of intense pleasure for the user, this is what makes them very dangerous because the user cannot feel any pain while high on the drug. Hope this helps you.
