What is known about the safety of custard flavoring? I heard it contains diketones, but would love to know more about why this is perceived as dangerous.
Just my personal opinion....I see the diketones scare is much ado about almost nothing. One person it seems got what is called popcorn lung.
I heard it contains diketones, but would love to know more about why this is perceived as dangerous.
Actually, the way I understand it, lots of people got it, but they were all factory workers in the popcorn plants. Only one consumer ever got it, which is probably what you're referring to, and he didn't get it from vaping but rather from a years-long habit of making microwave popcorn every single day, standing next to the microwave and deliberately inhaling the "buttery aroma" as it heated.
Diketones (at least diacetyl? I'm not sure about the others) are present in cigarette smoke, as well, so it's not like vaping them in your liquid is making it worse for you than than smoking. You're still (probably, as far as we know) far better off vaping than smoking, with or without diketones, but seeing as they are an "avoidable risk," then why not avoid them, since you can?
Dr. Farsalinos said they should be avoided, but what does he know?...
I like my custard with extra diacetyl. I would fight for my right to vape what I want, and for your right to know what's in your juice. We should all be allowed to make our own informed decisions.
I agree, because the entire point is knowing what's in there -- you can't really make an informed choice unless you're actually informed.I went to DIY for this reason (among many), but that only increases my knowledge so far -- the chemicals that really make up the flavors are still almost 100% mysterious.

This is the original study on diketones (diacetyl and acetyl propionyl to be more precise):
A new study verifies the lower risk-potential of e-cigarettes but identifies an avoidable risk
This is from the study:
"Tobacco cigarettes smoke contains both compounds, at levels 100 times higher for diacetyl and 10 times higher for acetyl propionyl compared to e-cigarette average daily exposure. "
Yet, people smoke and I never heard about a smoker getting popcorn lungs. It's good to avoid diketones, the safer, the better! But, personally, I don't think it's such a big issue.
