I vape in my house and vehicle, though I smoked only in the vehicle, not in the house. My husband has no issues with it. I vape in my parents' and my aunt's home, none of them are smokers, and they have no issue with it, in fact both my mom and my aunt will lean over to catch the cloud, to see what it smells like, my stepfather will come over and check it all out when I'm refilling, so HE can catch the smell of it.
In public places, I stealthvape, unless given explicit permission to go ahead and vape; what I do behind a bathroom stall is no one's biz but mine. In some places you can stealthvape without resorting to the bathroom, if you're careful.
2nd hand vapor presents no danger to anyone; it's pretty much the same as breathing air, though a) big clouds might annoy people, and b) some vapes don't smell too good.
