I’m with you on Devil’s Haircut. Just a great example of what he does.

I dunno, I’m an ex smoker. If I’m near a cigarette, that crap messes with me.

But vapers? I’ve had to tell a few off for not watching where they blow, but it is absolutely not the same as smoke. It doesn’t trigger the same responses, it doesn’t speed up my heart, clog my sinuses, our send me into a sneezing bout. I’d defer to any coherent data on its effects, but in terms of being intrusive, it just isn’t the same.
