Let's go back to this point by Azim:
I can find precious few clues about what standards - if any - the FDA uses to evaluate SE, besides that list which is already in the statute. Pages like this: Substantial Equivalence and this:
http://www.fda.gov/TobaccoProducts/GuidanceComplianceRegulatoryInformation/ucm271242.htm provide essentially no information.
However SE is a widely-used term in the food and therapeutic arenas: substantial equivalence site:wikipedia.org - Google Search
So this suggestion (and whatever comments you might suggest that we make, Kent) raises some interesting Qs:
1) Does the FDA have the authority to do something like this? We all know that it's an easy out for them to claim that they don't. It would be very helpful to discover how this process works in the context of both food and medical products, as well as in the tobacco area.
2) If the FDA were to do such a thing, could anyone complain about it? For ex., could a manufacturer of (say) combustible or even non-combustible OTPs argue that the FDA was either exceeding their authority, or perhaps sue them on other grounds based on different treatment of variegated classes of tobacco products? After all, they're all regulated under the same statutes.
3) On the other side, could the FDA be forced to promulgate such rules? (The chances of this may be remote. It's hard to force an agency to engage in rulemaking, methinks.) And if so, who would have legal standing?
BTW #2 and #3 are related to #1. For ex., if the FDA could argue that other tobacco products might be inappropriately treated by providing a "special status" to vaping that congress may not have intended, then presumably they lack the authority to do so (so some answers to #2 lead to #1). And if in fact no one can force them to engage in thsi kind of rulemaking, this may also mean that they shouldn't do so under some aspect of the APA (administrative proc. act).
These are deep and complex questions, as far as I can tell right now.
Good questions and yes, complex as well.
My view:
1. I don't know if the FDA would be able to change that on their own. The fact that our earlier view of using a different standard date from the impact doc (OP linked), upon further reflection, that had already been concluded and ended in the Feb '07 date, makes me think that they either couldn't or simply wouldn't entertain such a "threshold specs" predicate.
So... what does the FDA want to avoid. It seems, and they have said in the deeming doc, that they expect a mass exit from the industry by small vendors and you have to think that they would know that would also be a loss of jobs - d'uh. And that doesn't seem to matter.
What they might not want, are lawsuits. Zeller obviously didn't like the Sottera decision, even though he had a good understanding according to law, why the court had to come to that decision. Harkin on the other hand didn't seem to have a good grasp of that.
What I intend is to point to the fact that given the current grandfather date - the fallout of public opinion and from vendors, some of which may more likely put their money together to sue the FDA rather than spend it on attempts to file applications that from the history of the FDA on accepting isn't in their favor.
So....
2. Again, don't know, and I would guess there might be some complaints along those lines but they have similar 'exceptions', esp. the premium cigars and others, that I seem to have quickly bypassed by in looking for ecig data. It is almost a cliché that certain products, under the authority of some regulations skate by without much fuss. Usually a tacit agreement of congress people to scratch backs on various legislation and I'm certain they keep books on who did what.
3.Again, as far as the FDA goes, force can either come from the courts or congress. Enough pressure put on congress could have an effect, but they deal with so many more 'important' issues, it is unlikely they could see an electoral defeat from their views on ecigs - although IF it could be on the scale of say the NRA or NEA - even a 25% of constituents would definitely have an effect - but part of that is letting them know that it isn't just the user that's affected. The family, extended family (thanksgiving, easter, xmas) is also affected as well as friends and the workplace.
But... this courts are the ones that can provide the most incentive, imo.
