Very interesting discussion, I for one have been very interested in this as when puffing away in the car with children present it was somewhat of a concern, likewise it has been a concern for some restaurants and bars and all be it, that the toxin exposure of passive smoke of the cancer sticks is not present with vapes those using nicotine vapes may or may not put the non vaper at some sort of risk (?) not at all sure about this. I too use numerous mods, my latest is the itaste S.V.D 2.0 DNA 20 which I do favour a lot as it is one of a few mods that I own that will take a sub ohm coil. I am currently running a Kafun on it with a 0.8 ohm coil and quite happy with the result. Happy Vaping to all and a safe and happy vaping Christmas.
