Which is to say that there are least two factors (scarcity and lack of transparency) artificially inflating pricing.
On the other hand, in a truly free market for tobacco, a pack of American Spirits might only cost a buck or two; nicotine is our one and only drug-war success, and I think the state has demonstrated that it can extract profits from vice goods if it wants to.
You'd still pay $75 (is that the right price?) for an 1/8 if that was the only legal way to do it, even if you could get it illegally for $30. At least, I would.
