obliterans

Diacetyl attacks and obliterates the lung's tiniest airways, causing a disease known as bronchiolitis obliterans.

To be clear, there are no documented cases of bronchiolitis obliterans caused by vaping.

After workers at a factory that packaged microwave popcorn were found to have bronchiolitis obliterans more often than other people, some companies stopped using diacetyl as a flavoring.

Now the amount of cases was and still is negligible and while bronchiolitis obliterans on it self is extremely rare cases which can be tied even circumstantially to diacetyl are unicorns.

> Further, because smoking has not been shown to be a risk factor for bronchiolitis obliterans, our findings are inconsistent with claims that diacetyl and/or 2,3-pentanedione exposure are risk factors for this disease.

Now don't get me wrong diacetyl could cause or contribute to bronchiolitis obliterans or conditions that would allow the disorder to develop, but it could also be harmless or completely unrelated to the disorder, and even if is a cause so far all data we have points to the fact that it's extremely rare factor if one at all.

Because bronchiolitis obliterans was never attributed to smoking before, and that diacetyl hasn't been actually studied as the cause of bronchiolitis obliterans before it the "popcorn lung" ordeal.

This is what isn't being reported a proper report should read: "A study finds that diacetyl, a compound that might be linked to bronchiolitis obliterans is present in flavored E-Cig liquids Bronchiolitis obliterans also known as popcorn lung has been attributed to exposure to diacetyl during manufacturing of butter flavored microwave popcorn in a handful of cases in the United States.

Diacetyl is not safe to inhale and has been known to cause bronchiolitis obliterans AKA "popcorn lung" both in workers at flavoring plants and even cases like a man who ate multiple bags of microwave popcorn per day.

Smoking was never suspected as to have a direct to causal link to bronchiolitis obliterans as such while we advise some caution to be taken, there is no clear risk of bronchiolitis obliterans due to exposure to E-Cig vapor." But that report will not really catch any head lines so: "E-Cig's vapor will give you one of the rarest lung diseases" is used instead.
