Hmm, your first link only measured PM10 at a vaping convention. Have they compared this to the PM10 of a non-vaping convention in the same space with similar amounts of people? Isn't PM10 a lot less harmful than PM2.5? The article does discuss other studies on PM2.5, but they seem to be conflicting (some says indoor vaping increases PM2.5, some say it doesn't. Can you edit your comment to reflect the uncertainty here? For what it's worth, the marathons in China are quite fun.

Looking over the methods, I don't think this specific study included measurements of similar conference density. That said, I would suppose that most conferences wouldn't generate much PM10. Off the top of my head, you could probably compare it to a poorly ventilated kitchen. For scientific rigor I will edit to include this nuance. PM10 tends to be associated with more acute problems, while PM2.5 is associated with more chronic problems [0]. PM10 remains a closely monitored public health reporting metric. Taken together however, the notion that vaping is "just water vapor" is fraudulent (and knowing the historical context of the tobacco industry, knowingly so [1]). I will allow myself to complain that there are many threads in this comment section that make very broad statements that are unsubstantiated by science. Though I suppose it's the cross to bear for scientists arguing in good faith.
