I think (in agreement with many others who have posted) that this thread starts out with a false premise.
I don't do drugs, and don't drink*, but certainly think that the State has *no business* (including the often dragged out "heavily regulated and taxed" kind of business) telling people what they can't smoke, snort or rub into their bellies, to the extent that they do these things without infringing on other people's rights / liberty / safety.
Do you have the right to enjoy a fine whiskey, if there is such a thing? Sure. But you don't have the right to do that while you're operating a train full of commuters.
Marijuana, likewise. (Etc, etc.)
I guess another way to think of things would be to put yourself in the shoes of Brer Rabbit -- for the various for-your-own-safety prohibitionists to each trade in their bannin' hammers for some common sense? Oh, no! Don't throw me in that briar patch!

* Depending on how you define things. I have an occasional bottle of Woodchuck cider, which is similar in alco-content to beer; however, I've never been drunk. Whether that's "drinking" in your mind, eh, well, that's in your mind
