None. And furthermore I'm not sure it's even possible...
Premarket Tobacco Applications
I have just had the misfortune of reading
http://www.fda.gov/downloads/TobaccoProducts/Labeling/RulesRegulationsGuidance/UCM499352.pdf Recommended only for masochists.
Even though I'd read quite a bit about this topic, I was still stunned by the magnitude and complexity of the requirements. As many have said, the cost of preparing and submitting a PMTA would be staggering.
How staggering? If you don't have millions to gamble, don't even think of trying. You'd need to start with a law firm specializing in this sort of regulatory law. Then you'd need chemists, biochemists, epidemiologists, physicians, statisticians, a host of researchers in a variety of specialized fields, and God knows what else.
There is zero, nada, zilch chance that any small to medium sized e-liquid company (e.g., Vista Vapors, Cuttwood, Five Pawns, Suicide Bunny), much less any B&M vape shop, could ever get a single product approved. Same thing goes for small to medium sized hardware manufacturers. Only the very biggest sharks in the ocean have a chance. And even for them it's going to be an iffy proposition.
If I were in the business, I'd be making immediate plans to do something else. It's appalling how many of these business concerns have absolutely no clue.
There's an outfit in KC with 3 vape shops that makes and sells it's own e-juice. It's their main source of income. They make some good stuff and I have occasionally bought juice from them.
I visited their Facebook page (even though I almost never visit Facebook) and asked them about the Deeming. Their response was: "We have been long prepared for this. Changes may happen as this is just the first draft. But customers; trust me when we tell you we will be around!"
"Just the first draft." Well, what a relief! Everything will be fine. ECF moderators: You can shut down this thread now.
