Do not try to hold your e-cig in your mouth whilst peeing....I narrowly avoided disaster when my heavier than analog e-cig slipped out of my mouth!!...after a second or two of fumbling/jugeling, and peeing all over the place trying to save it, I caught it before it flew into the toilet!.....wheewww!....if you must vape and pee.....just sit down! .....Aaron
