Two things that puzzle me. Who has the answer?

Interesting abstract of a journal article here comparing the effects of e-cigarette vapor and cigarette smoke on indoor air quality:
http://informahealthcare.com/doi/abs/10.3109/08958378.2012.724728

Quote: For all byproducts measured, electronic cigarettes produce very small exposures relative to tobacco cigarettes. The study indicates no apparent risk to human health from e-cigarette emissions based on the compounds analyzed.

Here is the other study done recently: http://clearstream.flavourart.it/site/wp-content/uploads/2012/09/CSA_ItaEng.pdf

What you're exhaling is basically the same thing that comes out of fog machines, the moisture from your body mixed with PG and/or VG. Yes, it leaves a film. Try walking across the floor surrounding a fog machine after the machine has been running for awhile.

I figure it is like standing over a pot of chicken soup and smelling it. Or anything cooking.The steam gets in your lungs so anytime you smell something it is because you breathed it in. I hate the smell of somethings, like asphalt being poured on the roads. Or a fart which as we all know comes from the poop chute

Is vapor dangerous? i don't think so...
