I understand your reasoning. however, I can't see much of a public backlash, as I've yet to meet one non-vaper who knew anything about these regulations. However, I'm quite sure the professional anti-smoking brigade will kick and scream. Age restriction can still be applied at the state level, and I would expect that to occur regardless of any stay or ultimate outcome from the litigation. Even the plaintiffs in this suit (essentially us) already ceded that age restrictions and child resistant packaging should be required, and as you said, is already being voluntarily applied by retailers.
Age restriction is
already being applied at state level in all but three or four states.
I agree about the general public' apathy toward
vaping. I often hear that the general public' opinion has been poisoned by government and ANTZ propaganda, but i've yet to encounter any non-vaper who has a strong opinion about
vaping one way or another. Even those who are prone to believe it's probably not good, don't hold strong convictions about the topic. I've met some who don't like vapor blown too close in their direction, but that's just about as deep as their concern goes. I have heard some flippant comments about the size of the large vaporizers and how it looks douchey etc..., but very little about the health aspects.
I have tried to talk about the science and politics of vaping with many whose opinion i respect, but all i get is a cursory nod of acknowledgement. My own brother is a physician, but i've yet to have a discussion longer than 30 seconds with him about vaping. He is happy that i vape instead of smoking, would rather i don't do that either, but generally agnostic about vaping. That's really the extent of his interest in the topic. He is an eye surgeon though, so i cut him some slack !
