Well they are dangerous in different ways...
But not to belabor the point.
It is *good* to know what is in your juice. It is *bad* to demonize diacetyl at a concentration 88 times less than the lowest levels measured in those factories. And my example of 5 ml of daily vaping is really really high.
You guys are arguing this issue with the exact same argument people use when citing propylene glycol as "anti freeze" in e-cigs. It's the same argument. Exactly.
You take an industrial situation where every single breath had super high concentrations of diacetyl and compare it to a situation where the amount of exposure is minuscule.
This isn't radon gas guys. It's a food additive.
It's a food additive that has horrific consequences. Take in too much nicotine and you get jittery or the headache from hell. Take in too much diacetyl and your lungs start turning to stone. There have been multiple healthcare professionals in this thread that have said NONONONONO to any amount of diacetyl inhaled. You used the example of the popcorn workers. What about the people that got it just cooking popcorn at home? If you get crushed by a boulder weighing 2000 pounds, that doesn't make a 1000 pound boulder safe to have fall on you, which is the argument you are trying to use with diacetyl; it took the popcorn workers 220 ppm so obviously that is the dangerous level. You don't know if their lungs started to fibrose at 220 or at 10.
It is not safe to be inhaled in the continuous manner we do it. It is one of the few ingredients in our flavoring that HAS been tested for inhalation and the results are not to do it. Most of switched to vaping to better our health, and inhaling something down to cause the devastation that diacetyl does is not the way to do it. In addition, the desire of some vendors to deny and then defend their use of the ingredient is somewhat frightening and could understandably cause some to question the integrity.
And I will say again, my beef is not with Flavourart. Flavourart does not make flavorings for inhalation. Flavourart makes food flavorings, and there is nothing wrong with diacetyl being eaten- the documentation Flavourart has available on their web site makes that clear. So it's not a dig at the good ol' family man Max the Ph.D. chemist at Flavourart; he created a product that is safe for use as intended. That is his job. He is not a flavor designer for inhalation purposes, and I am sure that even if a flavoring company existed solely for the purpose of creating flavoring agents for inhalation, diacetyl would not be on the ingredient risk.
You want to use it, fine. But vendors owe the consumer the opportunity to spare their lungs any further damage by letting them know what products it is in so that the choice is in our hands. We spent too many years letting the cigarette industry decide what we can inhale. We're vaping so we can take back control of what we inhale into our lungs, and allowing vendors to hide behind skirts made up of creative statistics as opposed to making them stand in the face of scientific fact is nothing but a blatant attempt to wrest that control back away from us.
