Re: 2nd hand vape...?
There is some nicotine in second hand vapour, but it's an order of magnitude less than in lit tobacco, and has been described by those in tobacco control (who aren't fervently opposed to harm reduction) as being biologically insignificant - although typically I can't find a source/quote for that at the moment, but I'd not state that if I hadn't heard it from someone who was familiar with the science.
In short, it's not something to worry about, and certainly not compared to lit tobacco - you don't see non-smokers sharing a car with smokers pining for a ciggie once they get out. Quite the opposite, normally!
Of course, that doesn't mean you should pull out a series mod and hot box your non smoking, non vaping mates living room. Even with my little diddy devices, I always politely ask if someone minds if I have a wee tap on the device.
Common courtesy, innit?
