I actually had a search of the vaping forum yesterday to see if there was a thread on this after having watched this exact video on YouTube.
It looks like all this sh1t in the states is a deliberate misrepresentation. From what I can see, the majority of the people in difficulty have been vaping home made CBD oil, and not e-liquid produced by reputable companies.
I think most people who vape recognise that it's not entirely benign, but it's a damn sight better than smoking.
My view is that it's probably to stick to some of the less fancy flavours as the flavouring is where the risk is. About a year after I started vaping there was the diacetyl scandal and discussion about 'popcorn lung' etc. with a suggestion that butter/ cream/ cake/ custard flavours might have some risk attached.
I have mostly only vaped 'Bright Tobacco' for years, which is very bland. I do sometimes vape other stuff too, and don't worry too much about it.
I'd like to see continuing research and study. I don't trust much about the US these days though, particularly with the maniac they have in charge, so preferably independent European studies.
