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. 

Iagree with the other person my mom does that with her cooking and sometimes they taste the same as "unhealthy" junk ingredients

Your dog can sniff at or even eat a bit of catnip. the herb is edible and not harmful. just don't expect them to roll around like a cat would! your dog may scrutinize catnip by licking and smelling at it, or be totally indifferent to this stimulant.
