Well that is why people bring lawsuits, to determine these things. I did not bring a lawsuit. So I guess we will never know for sure what went on behind the scenes.
But yes, I chose to believe it was, as you note "an unfortunate oversight". Mostly because I felt, in my heart, that the person who mixed it really just did not know what they were doing. (no, really???)
(If it had resulted in permanent lung destruction, it would move from "unfortunate oversight" to "negligent tragedy" though, right?

I guess depending on whether it is yourself or a loved one how seriously one regards such things. )
My point about it has always been more that vapers have this unrealistic idea that everyone making ejuice knows what the heck they are doing, simply because they are in business.
I say you have to protect yourself. And that is why I am in favor of DISCLOSURE.
Not banning, not taking off the market, not regulating. Just simple disclosure regarding the ingredients you KNOW ABOUT. You
know something has been added to an eliquid, then state it. You
know your elqiuids tested positive for AP and DA, don't tell your customers who inquire about these specific chemicals that it's not there.
If anyone thinks that is too much to ask, to
honestly answer a direct question about something that you already know is in your product, then we agree to disagree.
