That's not really my claim though. My claim was that availability doesn't drive demand. The proof is in the pudding in the sense that I doubt any of you who don't smoke weed now will up and start if it's just available. And if I'm wrong I really, really doubt the reason will be "well golly, it's here so I must try it." Now I will admit that if a supply is artificially restricted that use will go up to satisfy the demand that was unable to procure the supply. However, mere legality doesn't mean people will try something. Salvia was legal for many years and I don't know anyone who ever tried it.You pretty much missed my point. I advise you to re-read my post. I was using prohibition to counter Nate's claim that more access will definitely not result in more usage. I think that's a completely false idea, so felt the need to debunk it.
But the original contention was basically that "when something is more available more people will do it." That's a theory I don't agree with at all. There are plenty of things that have been widely available that people don't buy. Mere availability doesn't increase a product's use. If it did the New Coke would have been a smashing success since it was everywhere during that glorious summer of 1985.
