Being new to this, I have a question for the old timers - Does frequent use of a e-device in a room leave a lingering room scent? We all know how cigarettes can leave a room smelling of cigs for ages, and the room where I do most of my pipe smoking is going to smell like pipe tobacco for a decade or two (Not a bad thing, IMO!). But I'm just wondering if there's any sort of scent impregnation from ecigs, over a long term. When I'm puffing on my epipe, my wife says the back of the house smells like vanilla, but the odor is gone fifteen minutes later. It doesn't seem to cling in the way that tobacco odors do. Is this an accurate observation, or will my study smell like Dark Chocolate a year from now?
