I believe diacetyl and acetyl come naturally from some fruits so a lot depends on what juice you are using. Pineapple I seem to recall is one.
Yes they are dangerous, but so we're the 40,000 extras in tobacco.
Temperature that you vape at might also be a factor.
Not much help I know. Afraid it's the best I can do off the top of my head.

I'm one of the people who believe the whole DA/AP scare is just paranoia from vapers who switched to a "safer alternative", only to force the belief that e-liquid should be completely safe. We would all like to believe that we are following the path of least resistance, and who wants to knowingly ingested a harmful substance if it can be avoided. *My tap water contains flouride, and I drink it.

With that said, there have been ZERO reported cases of any vapers suffering the effects of "popcorn lung". What's even more interesting is that the traditional combustible cigarette manufacturers included diacetyl at much higher concentrations than what is found in e-liquid, and NO REPORTED CASES OF POPCORN LUNG in smokers.

The reality is that the actual cases of popcorn lung are very few and stem from several people who developed the affliction while working in an enclosed space with huge amounts of the chemical in their immediate vicinity for years.

If you are worried, that is your right, but it is my learned opinion that your fear is without justification.

Like Dougie said, 600x more diacetyl in traditional cigarettes. no popcorn lung.

FDA BOC

To play devils advocate here, would popcorn lung not be diagnosed as something else in a smoker, seems many more respiratory issues stem from cigarettes. With that being said, I smoked for 30 years and have, at this point, no lasting effects from smoking.

    Acetoin can break down into 3-8%, or 3-10%, diacetyl, according to 2 sources I have seen. Assuming an equal amount per buttery taste, this at least reduces exposure to about a twentieth. If the flavor isn't buttery, it doesn't have much anyway. Other ways are known to get similar taste, the most known being butyric acid, which is more irritating, may cause breakdown of some other ingredients, and in excess, tastes like vomit.

    Diacetyl is inhaled regularly when smelling foods, but only popcorn comes flavored like 100 pounds of butter.

    A bit of a stretch to suggest that all cases of popcorn lung caused by smoking are misdiagnosed

    I'm not a doctor but, from what I've read on bronchiolitis obliterans "popcorn lung" using Google search it presents specific symptoms just as mesothelioma from asbestos exposure does. "Popcorn lung" can be caused by exposure to any number of things and actually nothing has been conclusive as far as the cause including diacetyl.

    It is rare and would be diagnosed for what it is I would think. Scarring of the lungs rendering them inefficient and useless.

    Does any of this guarantee us anything?
    No

    I know that even the most custard of liquids contain far far less diacetyl than cigarettes. Yet no reports I know of bronchiolitis obliterans with all the smokers who've died.

    Sorry to hear about your Dad, I hope he is doing well.

    Do you have anything that would support this claim? It would be huge for the community to be aware of it.
    The condition or illness caused by smoking is Obliterative Bronchiolitis. I almost lost my father this year due to it and YES it is caused by smoking and Emphysema from it.

    Cause[edit]
    Bronchiolitis obliterans has many possible causes, including: collagen vascular disease, transplant rejection in organ transplant patients, viral infection (respiratory syncytial virus,adenovirus, HIV, cytomegalovirus), Stevens-Johnson Syndrome, Pneumocystis pneumonia, drug reaction, aspiration and complications of prematurity (bronchopulmonary dysplasia), and exposure to toxic fumes, including: diacetyl, sulfur dioxide, nitrogen dioxide, ammonia, chlorine, thionyl chloride, methyl isocyanate, hydrogen fluoride, hydrogen bromide, hydrogen chloride, hydrogen sulfide, phosgene, polyamide-amine dyes, mustard gas and ozone. It can also be present in patients with rheumatoid arthritis.[8] Certain orally administrated emergency medications, such as activated charcoal, have been known to cause it when aspirated.[9] Additionally, the disorder may be idiopathic (without known cause).[10][11][12]

    Ummm, no.

    Diacetyl is produced during fermentation as a byproduct of valine synthesis, when yeast produces α-acetolactate, which escapes the cell and is spontaneously decarboxylated into diacetyl. The yeast then absorbs the diacetyl, and reduces the ketone groups to form acetoin and 2,3-butanediol.

    Diacetyl - Wikipedia, the free encyclopedia


    In food products
    Diacetyl and acetoin are two compounds that give butter its characteristic taste. Because of this, manufacturers of artificial butter flavoring, margarines or similar oil-based products typically add diacetyl and acetoin (along with beta-carotene for the yellow color) to make the final product butter-flavored, because it would otherwise be relatively tasteless.[6]

    In alcoholic beverages
    At low levels, diacetyl contributes a slipperiness to the feel of the alcoholic beverage in the mouth. As levels increase, it imparts a buttery or butterscotch flavor.

    In some styles of beer (e.g. in most beers produced in Britain and Ireland, such as India Pale Ale), the presence of diacetyl can be acceptable or desirable at low or, in some cases, moderate levels. In other styles, its presence is considered a flaw or undesirable.[7]
