Smokers Beware

While I don't put it past this government to attempt behavior modification, especially in light of the O-care law, I do, however, see a conflict for the political Left in that the purchase/use/ purchase of cigarettes generates a ton of tax revenue both via sales, and in the embedded taxes in a pack of cigarettes that are accumulated in the growing of tobacco, and the manufacture of cigarettes.

I doubt that this government will be so willing to lose that revenue, plus the billions in income tax revenues lost, and the millions of jobs from tobacco fields to point of sale.
There is a lot more involved in quitting smoking than just good judgement, the finances of forcing such a prohibition is phenomenal whether it works, or not.
...and that doesn't take into consideration the extra costs of dealing with the resulting black market, the sheer number of criminals such stupidity will create.
