If you think that it is not a right to self-medicate responsibly then you have declared your body to be property of the state to regulate as it sees fit.
Still I wasn't clear enough in that particular post you cite, so here it is. I should have said, "uninfringable right". Like the court has mandated with abortion. For example free speech has limits (too many now), as does religion. In unenumerated rights, we restrict sex from certain areas and restrict age of consent, etc.
Before you go off on calling me a liberal democrat, socialist, rights sucking, Constitution hating, DEAmen, read my last 30 posts. That should bring you up to speed. Then I'd be happy to converse.
