Recreational drug use and addiction are very different things. I agree that addiction should be treated seriously. But what you said sounds like saying we shouldnt normalize pedophilia when someone says we should normalize christianity. Recreational drug use has been normal since way before humans existed. Its just that every culture has its own set of drugs that they consider normal and the Murican war on drugs did a very good job in globally demonizing all drugs not considered normal in their own culture.
