Here is what I understand, E-cig suppliers cannot say that its a quit smoking aide, such as things like nicorette, (prescription pills that help with quitting (welbutrin?)) the patch, etc... If suppliers say that e-cigs are a quitting aide as those mentioned then they would need to regulate, test, etc...the e-cigs. I haven't seen any sites promoting e-cigs as a quitting aide rather all the sites i have seen basically say you don't have to quit just switch.
Now, I am thinking that the only reason why FDA is getting involved is because has anyone seen the price of regular cigs lately, in Washington state I was in a truck stop and the cheapest no name brand of cigs was going for 7 dollars plus tax, for brand name almost 10 bucks, and NYC is suppose to be at least 10 dollars a pack for cigs. Now if everyone or a mass majority of the people turn to E-cigs then the government looses all that money.
I think that the FDA wants to ban, or find a way to ban e-cigs so that way everyone would have no choice but to pay the high taxes that the government needs from regular cig purchases. On top of that there is really no way for the government to tax, e-cigs to get their hands into those of us who just switch. This is just another way for those in government to try and figure out a way to either regulate and put chemicals into something to keep people hooked so they can jack up the prices to keep that money rolling in. here is another example pot would be legal (meaning not need a prescription) if the government can figure out a way to make a profit on it. By making it legal with only a prescription not only can they tax it but they can also regulate the price. If FDA cannot figure out a way to outright ban e-cigs you can bet your bottom dollar that we will have to go see a doctor to get a prescription in order to be able to have the right to vape. this is IMO as I see it, and we can all thank big tobacco considering i also believe that they are the ones pushing the FDA to try and put a squash on e-cigs.
