Hi, as i know action is toxic in e liquid.. So if in aroma is 1% of acetion is it VERY accetable percent?
did you mean acetone? as in the paint and finger nail polish remover? I personally wouldnt use it in a vaping senerio. As far as being toxic, it can be at the right dosage... but then again, everything can be toxic in the "right" amount.
Someone know study/know more about acetoin and acetylpropionyl in liquids?
Dont you mean Wrong Amount?
If these members are that concerned then don't vape!
Some say it is better than smoking cigarettes...
Or, y'know, don't vape things that contain significant amounts of diketones. Of the flavorings I have for DIY I'd guess that less than 10-20% contain more than trace amounts and I did not go out of my way to avoid them. If I were concerned I would still be able to happily mix lots of good things without those flavors, even without their DX/V2 variations.
I think you're right though- an acquaintance of mine (a heavy smoker to boot) came by my house while I was mixing on my patio, a while back. The next time I saw him the first thing he said was "I've been reading about vaping. Have you heard of Popcorn Lung?" SMDH. I wasn't even using CAP VCV1 that day!
Obliterative Bronchiolitis is a real thing and my father suffered from it due to Emphysema and it caused a collapsed lung. So I had to run Oxygen lines through the house for him but you do not get it from vaping and the amount of exposure to the chemicals that could cause it is way more than you can vape in your lifetime.
