The only thing they can regulate is the nicotine itself, and this is where the choke point will be.
This is my belief as well -- nicotine *is* a drug, and so the FDA will do what the FDA does with drugs -- regulate it. Hence my stockpiling of 100mg nicotine. I don't think the FDA will make it impossible to get liquid nicotine, because there's far too much potential for Uncle Sugar to be able to stick his hand into pockets that want to buy it -- I think the regulations will make it a great deal more expensive. Having a nice stock of my own laid in will help me afford to make the transition to regulated nicotine. But I think even that will be challenged in court pretty successfully, given the availability of BP's nicotine products. But the cost may still be higher than it is currently -- somebody's gotta pay all those lawyers.
What will end up happening is that they will ban flavors, and you will end up buying unflavored nicotine solution. Then you will add flavors to dilute them yourself, or flavor packs will be sold " for baking/candy making purposes only" that are exactly the ratio needed to dilute most juices.
Ok here is where I get confused; when you say "flavors" do you mean ALL flavors, including tobacco flavors, like Virginia, or just the food-type flavors? Because I won't care that much if sweet-flavored vapes are no longer available; it will be disappointing because this Blueberry Muffin and Banana Nut Bread are awfully good, but they're not my main substitute for cigarettes -- but if they attempt to get rid of EVERY flavor, including the tobacco flavors, then I will have a serious problem, because so far I haven't been able to DIY-replicate the taste I like.[/quote]
The major flaw is that most of the infrastructure is on the internet. It isn't really legal for me to buy an SDcard with software to hack my nintendo DS, but that didn't stop me. Buying liquor or cigarettes online isn't an issue. You'll just see these companies either change the wording for their products or move out of country where they cannot be regulated. Regulating internet industries is something the FDA isn't really equipped to do since it is trivial for companies to skirt around and of no consequence for consumers to ignore.
I agree with this too, and with the fact that it's possible to buy things from the other side of the planet via the internet -- but the weak point there is Customs -- and no, they won't be able to seize EVERY shipment that MAY contain something e-cig related, they don't have enough officers for that, they don't have enough money to hire enough officers for that, and even if they had enough officers, this is the gov't we're talking about -- DOH! Keystone Kops, y'know.

But they *could* manage to seize enough to really hurt, if they wanted to go that route.
