All the literature for PV generally say, "what you see when the person exhales is vapor, not smoke, that is made up of mostly water vapor." 
So my question is; is it really water vapor? The main ingredient is PG and VG, neither of those are water. Is there something going on converting PG and VG to water vapor?
Sorry if I sound like an idiot, I just don't see where "water vapor" comes from.
