These regulations have already been approved. Honestly you do not need a PhD from Harvard to be aware that vaping food juice is much healthier than smoking dry tobacco and paper. It is common sense. That is how you know the decision has already been made. All of this approval stuff is a show. It's whatever companies that are loosing the most from vaping that are pushing this. The vaping Industry was a sitting duck. No big well funded, well connected vape businesses to defend against the lies. All fragmented and small the vape industry was stealing market share from drug and tobacco companies as well as governments that collect revenue from cigarette taxes. If the FDA actually was on the side of public health we would never have seen those rules. The mere fact that they would propose such rules tells you everything you need to know. It's game over unless there was a massive public outcry. And I don't see that happening.
