This has exactly zero bearing on FDA regulations. The draft of those regs are already on someone's desk, and have been for awhile. This is a case of false advertising. Had regulations been in place, Five Pawns arguably would've bypassed the labeling requirements anyway and continued to lie about what was in its product.
Vaping is a business, people. More than that, it's an entire industry worth billions. It's long overdue to stop hand holding around a campfire and pretending like this is a community of close-knit customers and vendors, because it hasn't been for years. It isn't a hobby, it isn't a subculture, it's a consumer product. It's no different than the soda you drink or the food you eat, or for that matter, the cigarettes you used to smoke. If Pepsi started including aspartame in its ingredients and then intentionally left it off the label, you'd be singing a different tune.
Five Pawns isn't some backwater garage juice company, either. They aren't a little guy operation. They are one of the handful who have a legit corporation, lab, marketing plan, and people who know what the hell they're doing. And that's kind of the point. They KNEW better and did wrong anyway.
