Nope, conservative, in that I recognize the fact that human nature, being what it is, is to go in the opposite direction of liberty without accountability. If the opposite were true, there would be no need for laws of any kind. That is the missing element in the libertarian philosophy, they always assume that human beings are, as a species, rugged individualists and that is just not the case.
I'm not sure what you're trying to say. In what way does the drug policy you describe differ from the libertarian drug policy?
