>Prohibition: Noun The action of forbidding something, esp. by law. A law or regulation forbidding something.

I don't see how it isn't prohibition. What differentiates it from any other prescription drug, especially those with recreational uses? Would you apply the word to marijuana, but not to OxyContin?

Regarding your last point: If there were a massive outbreak of something best treated by Vancomycin, I'm sure we would see arguments that it should be available over the counter to anyone who wants some. And that would be a terrible idea because of people who would buy a bunch and take it constantly, figuring it would keep them safe. And maybe it would, but at the cost of Vancomycin becoming a less effective treatment, and overall a lot more people dying.

That's one aspect of the argument that does fit pretty well with the debate on firearms.
