Perhaps I have a unique ability to see things from both points of view on the flavors subject. While I do agree that flavored e liquids are probably for the most part harmless I also see the reasoning behind the bans for the flavorings.
Its a difficult issue to tackle because either way there's gonna be an unhappy group. Of course the most obvious way around flavor bans is to label each liquid as tobacco or menthol flavor. Kind of like what Halo does. Halo sells a number of different tobacco and menthol liquids but each has a distinct flavor and flavorings added. By doing it that way there's no need to call your liquid strawberry of orange or whatever, you just call it tobacco with an added name to distinct one from the other.
This is one reason why I think Halo will not have many issues meeting whatever federal regulations are enacted...
