What is in the vapour of e-ciggies? Nicotine I assume and some kind of flavouring?

In which case it's sucking in what is in effect flavored insecticide. Just do me a favour an lay off the Organophosphate...

Joking aside I have to admit that vaping appears much safer than tobacco and a lot less smelly. Still would not like to have to sit next to someone who was doing it though.
