My thoughts exactly...don't get me wrong, I agree vaping clouds are much cleaner than/ preferred over cigarette smoke but I think you are kidding yourself if you think that it is just "vapor". The fact that vaping clouds linger rather than immediately dissipate is good evidence that we are releasing chemicals into the air - rather obvious since we are burning PG, VG, nicotine and flavoring. Directly supports my opinion that we should be respectful of non-vaporists as we are of non-smokers...don't vape where you would not smoke a cigarette! Might seem off topic but this discussion and suspectK's post presented an irresistable segue to vent my frustration with the self-righteous vaporists I've found on ECF that insist on vaping in inappropriate public places.
