Been mulling and my conclusions so far are:
vaping is killed dead altogether in the hope that children under 18 buy cigarettes, - and we go back to cigarettes - get hooked on all the additives and posions that BT puts into them, pay taxes and die.
Vaping is killed dead unless you're BT, who will continue to put in all those addictive additives in those ghastly (legal) little stick batteries. Everyone else can and will smoke cigarettes and die, under or over 18 be damned.
Then:
State politicians rely on the two points above to get "their" money back to where it was.
Or:
State politicans believe the rate of smoking will continue downwards and start belly aching VERY loudly at the loss of vape tax opportunity.
State politicians will congressionally vote that vaping stay legal at least through products to 2016, and then tax them as highly as cigarettes - or more - by claiming they're lots more expensive BUT they ARE a healthier alternative.
So: As we DO know it's ONLY about money, health benefits be damned. The main question is:
Are Fed and State betting on everyone returning to smoking, and only be given smoking as a choice (other than those horrible little BT sticks)? OR
Are Fed and State betting on smoking as a trend will continue to decrease and the only thing that can rake in "their" money is by taxing everything vape-related to make up the difference?
