I vape all over my house. My husband is a non-smoker, and he finds the smell either non-existent, or pleasant, though there is one that he finds a bit less pleasant, since it's rather smoky; if I vape that one at all (it's high VG so I don't vape it much at all), I do it late at night when he's already gone to bed -- the smell is gone by the time he gets up to get ready to go to work. I also vape in our truck when we're out and about, and he has no problem, doesn't roll down his window or make me roll down mine -- in fact if I roll it down because I feel claustrophobic, he asks me why, since there's no smoke. My usual vape makes it smell like there's a blueberry pie baking in there.
For me, the ENTIRE point when I started this was so I didn't have to go outside, but could vape in my home. My husband knows very well that if he'd said ANYTHING about the smell of it, I'd have thrown a screaming fit on the subject of those who just WON'T be pleased no matter what, or I'd have gone back to smoking -- or both, actually. In fact, if he'd said anything about the smell of the vape, when I went back to smoking I'd probably have stayed indoors, rather than taking it outdoors -- to give him something to compare the vape to!
I also vape in my mom's house; she finds the smell either non-existent, or light and pleasant, and she has COPD, but the vapor causes her no problems. Ditto my aunt, though she doesn't have COPD, but she's a NEVER-smoker, and finds the smell either non-existent or light and pleasant.
