I don't think they're "letting anyone" get away with scientific fraud. I think big tobacco is a bit confused and desperate at the moment, honestly.
The anti- movement, however, will stop at nothing. They have demonstrated this, and in part, I understand the concern, but it's really really DUMB to take away a harm-reduction method that actually decreases smoking.
However the anti- movement is pretty black and white. Even if their overfocus on vaping led to smoking's RESURGENCE, I think they'd consider that a win, as they see absolutely no "spectrum of harm." Just harm.
I say, instead of all this craziness, we just pick a state that sucks, move them all there, and let that state be nicotine free, and if it was AZ, I'd be WILLING to move, if they'd all just SHUT up. Maybe they can secede from the Union as well, and just stop being an annoyance.
I don't understand how one group of people can be so solidly one note, either. They're a boring lot, I'm afraid to say, many of them. That's what happens with propaganda and brainwashing. I've met a few cultists, and really, individuality becomes completely squashed, and it's a shame.
I do consider the anti-s a "cult" in some ways....
