Yeah, I read that study. It was a lot of "Gantz said," with very few actual numbers, and god knows whatever cattywomper studies that were "included" in that article. I don't believe much of it, even the stuff "supported" by studies, as I have seen other studies reporting that dual use doesn't bring as much HARM reduction as switching to vaping completely, but I have NEVER heard that dual using cause "5 times" the harm as smoking or vaping alone. That doesn't make any actual sense, and even if it did, I think it's been refuted by other studies.
Keep vaping (unless you want to believe in this article) I saw many troubling things within it by not much actual "fact." I mean, if you extrapolate "dry hit" studies and etc., well, yes, you are going to get troubling results, but the real world doesn't function that way. I don't deliberately turn up my MTL tanks to 120 watts and vape them that way, it isn't pleasant.
Since I'd like to die of a heart attack anyway, I'm not too troubled, other than the obvious misinformation that was contained within it.
It read: Bogus study, bogus study, bogus study
Long interview with "Glantz" where he MAKES UP FACTS about dual users and etc. That was backed by NO research whatsoever.
I wouldn't sweat it but the choice is up to you, obviously.
