WOW! I was so taken with this build that I had to show my wife. She watched the whole build part and then when the camera went "back up" and showed the dude, she said something like "he's not my type, at all". Type or not, this is a really sensible build!
Isn't what causes "popcorn" lung?
Diacetyl is a diketone. Meaning it has a specific molecular shape with a double bonded oxygen hanging off both tails of the molecule. It's the original apparent cause of some factory deaths, and especially workers in popcorn plants needing lung transplants.
The stuff is naturally present in butter and other foods. But it's used in high concentrations in e.g. microwave popcorn. It's fine to eat. Not to inhale.
The factory owners started using alternative compounds like Acetylpropionyl, because it also tastes buttery. Also a diketone chemically. So NIH toxicology labs ran tests on rodents and confirmed that above 150 ppm both caused irreversible damage to the fine bronchioles, scarring them. So OSHA published requirements and guidelines. At least they covered diacetyl, and explained the issues. Ya can't breathe that stuff.
But the food flavoring makers aren't selling food flavoring specifically to be inhaled, are they?
There are a lot of potential buttery creamy flavoring molecules that aren't explicitly listed by OSHA, but are also diketones, and what do you think, are they used in those rich-tasting custardy juices? How about Acetoin, whose molecule looks a lot like Diacetyl's?
The most recent testing was on Acetoin, which also tastes kind of buttery, and is not a diketone, it has a single ketone oxygen. Turns out tests on rodents show no bronchiole damage from Acetoin. So there's at least one buttery flavoring that seems safe.
You think the juice blenders are going to get into learning complex chemistry and toxicology when all they have to do is pack their vaping liquid with sweeteners and flavoring, and cash the payments? Forgive me gentlemen, but I think the ONLY sensible thing is to blend our own, and take it easy on the amounts of ANY flavoring. Sorry, end of rant.
Still not finished with that batch, pulled out the GP Heron clone and have been vaping it ever since after a bit of Dremeling on it.
That's the Mad Hatter's Tea Party approach. Effective! Leave the smoking ruins for the approaching barbarian horde and just move on.
This is the first of my 3 Tobecos that smells like oil. Not bad like a tool from Harbor Freight though. Off to the wash with her!!
