Here is the thread.

The original issue was diacetyl butter flavor, which has been known to cause nasty lung damage, and has since been removed from US flavorings. Diacetyl is just one example of a type of flavor compound generally known as diketones, but include other similar compounds, and are in general what is used to make custard/buttery notes. Acetoin and acetylpropionate are also of this type, and they have not been removed, or probably not. Capellas do state in bold face that diacetyl is gone, but they do use these other custardy flavor compounds still. As they should, since vapors are certainly not the only people that use flavorings.
Are these other compounds in custard/buttery flavors dangerous? I do not know, as our method of use is very different than baking, and the whole lung damage thing is not really well studied. So I make no claims to danger, but for now until we learn more, I am avoiding custard notes. Capellas waffle is another questionable one. Linda at Perfumers Apprentice is being very proactive about this and stating which flavors contain custard notes, and coming up with flavors similar that do not, and I totally applaud her for this.
Has anyone been injured by these flavors? Not that we know of, but the type of damage that occurs is gradual, permanent necrosis (death) of lung tissue. The popcorn workers that died or in need of lung transplants (only treatment) several years ago put all the focus on diacetyl, but these other compounds do have reports of similar deaths/injuries as they are chemically closely related and react similarly as diacetyl. And while we do not know for sure, capellas vanilla custard more than likely has at least one of them in it.
Flavors are the biggest unknown of vaping, safety and healthwise. How we use them is VERY different than eating of just smelling them. And the nature of this disease is such that I do not want to risk it. Plenty of great flavors out there without risking losing a lung or my life. This isn't about irritation or even blisters (what inhaled cinnamon can do from cinnamaldehyde), its about gradual
permanent loss of lung function that probably starts out as simply shortness of breath. Very rare in the general population, but more common with processed food workers. Where do we stand? Not enough data, but not worth it to me to take the chance.
I'm a chemist of some 30 years, and I have had these concerns since day 1 of vaping. Seems those that cater to our flavor wishes are finally starting to get it, at least Linda is, which makes me want to order from her just to give a smart woman like her support. We need more like her, regardless of people's opinions of her flavors (some great, some not so great, like any other supplier).
Had some serious oral surgery yesterday and the pain pills or something kept me awake half the night. Glad I'm not at work right now!
