I was hoping that experienced vapers could chime in with good disarming phrases to use when people are offended when you vape near them. Because I'm so new I find myself bumbling with an explanation that it isn't smoke it's just vapor. Well, what is vapor??? It can't be just water? Vapers are inhaling PG/VG and flavoring at the very least... are there sources that I can cite that will explain what the "vapor" really is???
