Bronchiolitis Obliterans (popcorn lung)
Not an opinion.
Let's put this discussion in proper perspective. You previously said:
The chemicals in question WILL damage your lungs. That is an irrefutable fact. The damage is irreversible and cumulative. So even the tiniest amount will cause a tiny amount of damage that adds up over time, and it doesn't heal, ever.
You provide a link and don't draw attention to the part that says what you said above. I do a word search on the word "amount" and the only hit says this:
Diacetyl is approved by the Food and Drug Administration as a safe flavor ingredient, but there is evidence to suggest that inhalation in large amounts is dangerous. There are currently no warnings from federal regulators about diacetyl.
Inhalation of large amounts. This tells me that if you aren't inhaling large amounts it is not necessarily dangerous. Smokers have arguably inhaled a fairly substantial amount. Here's the part where you get to say that perhaps all smoking health issues relate to lung maladies have routinely been misdiagnosed when this is occurring. Yet, if vapers are now vaping, and condition is not reversible, then it would mean that vaping isn't going to make you feel healthy as your words before make it come off as there is no way around getting this. You inhale a tiny amount (over many years) and you're doomed. Oh, but what's that article say about this condition and non-smokers?
Non-smokers may be at higher risk for this form of bronchiolitis obliterans.
Along with:
So, this notion of can't have any of it, when the primary resource driving ALL the data is saying there is essentially an acceptable limit. If there wasn't acceptable limit, then there would be zero ppb as the number that makes sense to go with.
I stand by notion that it could be healed. If you have full blown case of it, and no chance for a lung transplant, and your system is going to reject functioning lung in favor of the disease, then I would plausibly agree with your point under the stipulation of inhaling large amounts of it, but not under the notion of tiny amounts of it over time.
Do you dispute that cigarette smokers have been inhaling small amounts of it for many decades? And that this number found in cigarettes is, in some cases, significantly higher. Why no reports of smokers having bronchiolitis obliterans, caused from smoking? Why not list that as a possible cause on the article you linked from? Would seem easy to do so as I'm thinking no one would dispute this as smoking seems to cause a whole list of maladies. Why no current reports of vapers having it? Oh, that's right, it takes a long time to get it, due to the cumulative nature of it. Thus, smokers could get it, as well as ex-smokers, and there could plausibly be no way of knowing if ex-smoking, now vaper got it from decades of smoking or many years of vaping. But surely it is one of the two, even while non-smokers may be at higher risk of (a form of) it.
