This report is incredibly vague, while at the same time incriminating vaping products with little evidence.

A background on Diacetyl:
- A butter flavoured compound used in artificial flavourings, and was once commonly used in e-cigarette flavours. Risks were known, and it was used in limited capacity.
- Harvard Medical School published a study stating to have found Diacetyl in eliquids (1). This was no surprise, it was never intended to be a secret. The Harvard Study also failed to disclose within their study, a control group to compare their findings - the most important being that tobacco cigarettes produce more than 100x times more Diacetyl than even the most offending eliquid (2).
There are no records of bronchiolitis obliterans on record as a result of smoking.
With over 15 years of use worldwide, there have been no reports whatsoever of any ecigarette user contracting the disease.
Use of the ingredient was almost completely eliminated from eliquids in North America, regardless.
- With nearly zero likelihood of a North American product containing any significant amount of Diacetyl, the chances of anyone contracting Bronchiolitis Obliterans due to vaping is infinitesimal.

Bronchiolitis Obliterans (popcorn lung) is indeed real though extremely rare. It is caused by accute exposure to Diacetyl, a chemical used to enhance buttery and custard flavors in the food industry (and the vape industry for a short time ending 2014/2015). Diacetyl is also a naturally occuring chemical produced in various fruits, vegetables and plants. The most notable of which is Tobacco. More on that in a minute.
I think it is quite questionable for any educated health professional to pin the blame on this youth's lung injury on popcorn lung, as there has been a plethora of scientific data negating the possibility. I assume willful ignorance is to blame here, an utter failure to research the plethora of available data. There is 750x more diacetyl in a pack of cigarettes than there is in a days worth of vaping nicotine fluid, and to date we have no confirmation that smokers are getting popcorn lung.
To put that into perspective: A vaper is exposed to 9mcg of Diacetyl (study by Allen et al., [https://ehp.niehs.nih.gov/doi/10.1289/ehp.1510185]) per day whereas a pack a day smoker is exposed to 6718mcg (Fujioka and Shibamoto study, [https://onlinelibrary.wiley.com/doi/abs/10.1002/tox.20153]) per day. Yet popcorn lung has only been diagnosed in those popcorn factory workers almost 20 years ago, there can be no...

It should be noted that the Harvard study from 2017 that identified diacetyl in several samples of nicotine-based e-liquid did not compare the levels to that of tobacco cigarettes. In fact, tobacco cigarettes contain 700 times the amount of diacetyl found in any of the samples.
The vaping "community" communicates constantly, and when this study's results appeared, most manufacturers removed diacetyl from their recipes in the interest of safety. Further, in developing the TVPA in 2018 to regulate the vaping industry, Health Canada guidance strongly advised against the use of diacetyl in vaping e-liquid (1). The government monitors the manufacture of this liquid to ensure compliance.
According to press reports, the patient bought his e-liquid from a Canadian online vendor whose inventory would be controlled by these regulations.
The statement in this paper that diacetyl is present in many flavours is therefore incorrect and misleading.

It's interesting that I see no mention of THC products that were determined to be the cause of the issue of the cases throughout the United States. With the teen here getting their products online from an American company. Maybe the evidence hadn't been announced at the time of writing but this article should be amended to reflect this. The broad use of the word Vaping as a reason or cause in and of itself is misleading and uninformative. Its like blaming the needle a heroin junkie uses when the overdose on bad product. And it is the bad unregulated product in the US that is the Issue. THC oils cut with vitamin E acetate and laced with toxic pesticides that has been on only common factor found. This might have been learned earlier had the medical establishment taken appropriate steps to gather evidence and take a proper history. unfortunately by the CDCs own admission this didn't even begin to happen till after the 9th person died. The rampant misunderstanding that is being spread thanks to the general term of vaping has become so widespread that the doctors themselves failed to do their duty and thus the American public was mislead with false data often leaving people taking precautions from the wrong product.and ultimately dying. We Must do better to ensure that this kind of behavior is not condoned or even given enough weight to get off the ground lest we find cause to over regulate one product that halps while trying to safeguard against something else e...

As previous chief of Internal Medicine at a large academic hospital about two years ago at a medical conference I said residents interested in entering a subspecialty should think about respiratory medicine as with the legalization of marijuana and vaping there will be lots of work for chest doctors.
