News I was reading was that the lungs were found with a some kind of oil build-up in their lungs.

Always thought that bio-diesel showed promise. Those particular reports seem to boil down predominantly to known symptoms resulting from the inhalation of Mineral Oil fumes (not the alcohols PG, VG). Interestingly, Palm Oil (cheap source for Glycerin) is “relatively rich” in Tocopherols (that is, Vitamin E molecules), which decompose when heated. If Acetic Acid was possibly added at some point, chemical analysis might indicate the (reported) presence of Vitamin E Acetate (a salt formed with Tocopherols and Acetic Acid). Just sayin’.

Oh well, time to move onto some other fashionable scapegoat with which to slander the sin of “vaping”. 
Of prime importance will remain the skillful conflation of Nicotine with already demonized “psychotropics”.

Having worked with Acetic Acid for decades, I would have to say only a total idiot would think of putting that in something you’d inhale. But I guess that’s the point.

I guess that I might have been wise to hold back the Vinegar from my “Free Range Non-GMO Corned Beef Shanks” sauce. Just wanted to “marinate the meat” (so to speak). Much better bovine “bouquet” that way.

The Acetate salt appears to be a fairly common formulation of (the various) Vitamin E molecules (up front).
Acetic Acid is item number one on this list of “can be used” acids for Nicotine Salt formulations. Who knew ?

I guess that would be the difference between a process and an additive. That stuff will literally make your sinus’ bleed.

I can dig it. Similarly, Hydrochloric Acid, Sulphuric Acid, Citric Acid (and other common ones widely used in medicinal salt formulations) are not desirable to play with (in any appreciable quantities, whether complexed as a salt in solution, or not) where it comes to one’s internal mucus-membranes - which can be quite finicky.
The FDA places Acetic Acid on their recent proposed list of Respiratory Toxicants (RT) appearing below:

Right on cue, the administration is rolling out it’s most erudite intellectual heavyweights on scientific matters:
It will likely be hard to argue with the gravity of such highly influential thinkers of our time in the White House.

This looks like interesting information (indicating that certain Vitamin E Acetate additions were intentional):
(Leafly; September 6, 2019): “Vape Cart Additive Makers Pull Products as Others Go Dark”
Clear Cut contains vitamin E acetate. Jones confirmed in a letter to Leafly that Clear Cut contained tocopheryl-acetate. Jones wrote Leafly that he had permission to use it from the Oregon Liquor Control Commission and thought it was safe. … The popular illicit market diluent thickener Honey Cut, based out of Los Angeles, may contain vitamin E oil, according to independent tests …

(Leafly; September 9, 2019): “Vape Pen Lung Disease Has Insiders Eyeing Misuse of New Additives”
Industry insiders who track the legal and illegal vape cart markets closely tell Leafly that a new type of additive started showing up in late 2018, and has since become widely used in underground markets. It’s a novel class of odorless, tasteless thickening agents. These liquids come in different proprietary formulations manufactured by both legal, above-board companies and by shadowy underground operations. This new additive may or may not play a role in the current health crisis. But it is one of the major new ingredients in illegal vape cart oil in widespread use this summer.

oh, come on. as you pointed out yourself, glycerol and PG are also on the list.
Maybe you guys guys can start your own quiet little thread about the dangers of putting acetic acid or citric acic in your juice?. I’d be seriously seriously intersted to know if there’s any real concern here, given that some of us do talk of adding vinegar, lemon . or commercial “sour”" to our juice.
Suspect you’re just taking the piss, in fact. But you’re so freaking deadpan it’s hard to be sure.

Hi Jay, Harlan and I were having a rational discussion there - no parental guidance needed or desired.

nothing to do with parental guidance. If you’re seriously suggesting i should throw away my natural lemon extract, if i don’t want my lungs to suffer, then i want that discussion out there in it’s own thread, where i can read it at my leisure, not conflated with all this gubbins. But, what the heck, that’s a pretty big “if” methinks.
