It's not nicotine you need to worry about when vaping around others, because it would not cause any problems to anyone. It's the fact that there is no tar or any other obnoxious chemicals contained in the vape juices, except glycerine, vegetable oils, fruit flavourings and minute amounts of nicotine, that is found in most vegetables anyway. Vapour clouds (not smoke) won't do anybody any harm. Most people who do not smoke or who have never smoked, are ignorant of the fact that vapor clouds from these devices, contain no harmful polutants.
