Jman8, that's a lot of text you just threw at me. The bottom line is that Diketones present a serious health risk and vapers consume more of it than ever before. I moved no goal post and if you read my previous posts you'd know that my only concern is not full blown popcorn lung disease It is lung damage/dysfunction caused by diketones from vaping. Lots of great reasons to think I am right to be concerned. I am genuinely mystified by your resistance here.
Part of my resistance is that you are not presenting evidence for reasonable concern. You are saying diketones destroy lung tissues, and not backing that up. I believe you can cite things to somewhat back up that claim, but not for vaping. I think you know that evidence does not exist, but are harping on chemicals that have been shown to be associated with lung damage.
Another part of my resistance is that these chemicals have been inhaled in great numbers (well over alleged safety limits) for essentially the last hundred years (maybe last 3000) by smokers, and yet the evidence that you could provide wouldn't really take that into account. So, you are saying it ought to be removed from vaping, across the board, even while smokers who have inhaled it have not shown the specific condition that is primary focus on this ongoing debate.
Overwhelming part of my resistance is that you think your fears ought to apply to everyone else. I would suggest if your fear is this great that the thread ought to really only be about, "I will be stopping vaping very soon because I am scared to death that vaping will destroy my lungs."
I would say that vaping air will plausibly destroy a persons lungs. Just as safe to play the "we don't know" and "don't have long term data" on that, and so is nearly as sensible to me to argue that just cause we don't have any reported cases of vaping air causing lung damage, doesn't mean we won't at some point, and who's going to say vaping air is healthy for lungs? That we aren't vaping air, and instead are vaping things that are very unlikely to increase lung function, while very possibly manifesting in some degree of damage, would be possible reason to avoid it altogether. Until you realize that there are lots and lots of things on the planet that are inhaled by lots and lots of people (arguably all of us) that will produce lung damage.
Knowing that everyone that has ever lived here has or will die because of things found in this place does make for more reasonable concern for fear. And yet, even this fear can be overcome.
I advocate a safer vaping experience by telling the truth of the dangers of diketones, and you tell me "just don't vape". Wow. Just wow. You treat me like non smokers treat smokers.
Let me know when you get to the part about telling the truth about vaping diketones. I'll be sure to sit up and take notice.
