This makes me even more glad that I'm just about to start making my e-liquid using PEG400 -- I think it would be pretty hard to outlaw that stuff, it's used in SO MANY! products, but it's rather outside the norm for vaping. And I have some nicotine, and planning to get more before the FDA decides to muck everything up. So the only problem will be the flavors, and since I'm also moving away from tobacco towards fruit flavors, maybe other sweet flavors eventually, flavors may not be much of an issue as far as my own use.
Also -- approval may be significant for products not yet bought, but for the products I already own... see my sig line -- pry them from my cold, dead fingers before they'll get my PVs from me. So yeah I see a mechanical in my future, since those are a lot more straightforward to maintain, and should be able to outlast any electronic PV.
Factors like these are why I really don't see a worst-case scenario happening. No, things may indeed change, and not for the better, but the cat's out of the bag now, and you know, it's hard to everything to get a cat back in a bag it's once escaped from.

why are you using peg400 instead of pg? is it easier to get for you?
