I've seen a couple of these sort of things now, and they've raised questions for me...
Most/all of them at a minimum hint at home made juice being a problem. I don't consider it automatically worse than commercial stuff?
They all mention how "nicotine juice is strictly regulated" but fail to mention shortfills (a big part of most of their sales, but not "nicotine juice"). Aren't shortfills exempt from the ingredient regulations and approval requirements?
Again, doesn't mean shortfills are automatically worse, but it's not illegal for them to sell recipes that'd never pass tpd - not that all do, but they could and some certainly do.
