If it's not bad for the lungs, we should fluoridate vape juice.

Probably shouldn't inhale vaporised flourides.

Fluorine is really really bad for your lungs.

Well, never mind then.

I think anything with nicotine in it is bad for you

Nitpick, but it doesn't always have nicotine. Not to say it isn't harmful.
- Well its not good for you so I can't say I'd recommend.
  What concerns me is any positive publicity on sm* or va*. We don't need more people hopeless addicted.

My two concerns are that, you wouldn't hold the vapor in your mouth long enough for it to actually be helpful, and with some people vaping occasionally, and others doing it constantly, it would be difficult to keep the fluoride levels high enough for casual users to get a benefit, but low enough that all-day every-day folks don't OD.

Both of those apply to tap water too but municipal governments still spend millions every year buying industrial byproducts for "public health"
- name one person who died of fluorine poisoning from drinking too much tap water.
Or you know, make vapes illegal
- Your comment reminds me of a dog that barks every time someone walks past the house.
- Why make them illegal? I used a vape to limit my nicotine intake and weaned myself off of smoking (and vaping) completely. It still sucked for the first 6 months and the occasional random craving that comes from being a smoker for over a decade, but at least I fought each part of the smoking addictions separately which made it bearable.
  For clarity, I got 0% nicotine vape juice for a month or so before I quit puffing completely so let the withdrawal from the substance run its course, and then had to deal with the psychological side of things. Which was VERY annoying. Everytime I'd do anything where I'd normally smoke triggered a craving.
- Vaping was integral to me quitting smoking. Vaping isn't the problem, advertising and accessibility of nicotine to youths is the real issue.

If it's not oxygen it shouldn't go in the lungs. Full stop.

The 78% nitrogen hanging out in the atmosphere begs to differ
- You can also breathe in smoke, that doesn't mean that you should. Can and should are the keywords here.

No.

Interesting. Do aerosolized fluoridates adhere to teeth?
