Yes, some people DO care about facts. I'm one of them. You're not. Over and out

Vaping Myths: Are we exhaling water vapor?

I think it would be a gaseous solution of nicotine, PG, and flavorings... but Im not a scientist
Wow, this has devolved into semantics over the words "steam" and "water vapor". According to Wiki:
Sorry NCC, even from my limited knowledge of chemistry it would seem safe to use the two words interchangeably. It's not really the point we're discussing anyway. I also see no mention of dust particles after a quick glance at the wiki page on steam.
The bottom line seems to be that you, Kristin and I all agree (along with the OP DC2) that saying we are exhaling pure water vapor (or 99% like mentioned in my supplier claim thread) is erroneous.
Actually, the main purpose of this thread was to get people to stop calling it water vapor.
Barring that, I wanted to at least feel comfortable being able to tell people that it is not water vapor.
But in order to do that, I personally need to know that is true, and I also need to know what it actually is.
Telling someone it is not water vapor, I would expect them to ask me to explain what it is then.
I would hate to have to say that I don't know for sure what it is, but to trust me that it isn't water vapor.
I always considered it to be pg or vg vapor or a combination of both
Some of the things I've noticed have led me futher and further towards my conclusions...
I have noticed that I get much more vapor when it is cold outside, or in air conditioning.
This coincides with the idea that "fog" is "condensing" onto the vapor particles that we are exhaling.
Also, PG and VG are both humectants, which means they absorb water from their surroundings.
So they steal it from our body on the way in and the way out, and from the air after it is exhaled.
Finally, when I have a fan turned towards me, and the vapor is blown back into my face, I can feel how (amazingly) cool it is.
This is in spite of the fact that it is heated when it is inhaled, and our bodies should maintain it at 98 degrees until we exhale it.
I'm still trying to figure out exactly where and how this phenomenon fits into the scheme of things.
I to have noticed that. Maybe it condenses on your skin and evaporates making it feel "cooler". Sorry if that's been answered, I haven't read the whole thread. Either way it's not burnt smoke. Vape on!

I think its more like how if you dip your hand in a solvent like acetone your hand feels really cold after you pull it out... not because the solvent is cold but it "steals" heat from your body in order to evaporate.
Of course I care about facts. What a ridiculous assertion, considering my involvement in smokeless alternatives activism.
Edit:
I'm just deleting the rest of my post, as it goes over the same stuff and I already made my point, so I'll spare others having to read it all over and stop the off-topic discussion!
We had an ECF member that is in the pharmacy industry and she looked it up. She couldn't find any that were made with PG anymore. Not sure how polyethylene glycol differs from propylene glycol - they sure sound similar though - the Wiki description sounds like it is used exactly the same way as PG!

You can blame my highschool for not teaching me that distinction
I stand corrected.
I stand corrected.
Off topic part: Anyone know why they quit using it?
On topic:
I just can't let a good heated discussion die like that! The Russians have a saying: "If you're going to die, then die with music!" It means go out with a bang, go down fighting.....
So where did we leave off? DC2 started the thread to discuss the inaccuracy of calling the inhaled/exhaled stuff "water vapor" and to get people to quit calling it that. We all seem to agree that technically it isn't 100 percent water vapor. I think there is a general consensus that most don't want to give answers that sound like a long-winded ingredient label if someone asks us. It is NOT smoke. So....
What the heck are we going to call it? Condensate isn't descriptive enough (condensate of <..........>). "Fog" is just as bad as "water vapor".....implies nearly 100 percent water in some state.
IDK
I think I may just start telling everyone that asks that it's "nontoxic flavored antifreeze - Yum!". lol
Maybe just "Yummy stuff, with nicotine added for addicts like me". Maybe we need a poll for how to answer the "What is that stuff?" question.... Hmmm.
Personally, I'm going to tell people it is the same thing produced by a fog machine.
And if I'm feeling randy, I might add that there will be insignificant traces of flavorings and perhaps nicotine.

For a quick answer, Liquid Vapor is more accurate imo. That's what I'll be using.
Nobody - especially a Supplier registered with ECF - can say that, "Exhaled vapor is 99% water". If it were reported to us that a Supplier states that on their site, we would ask for the proof (an acceptable reference). As there is no such source, they would have to remove or modify the statement. It may be true - but there is no research that says so. In fact, Laugesen says, "...the exhaled mist of the e-cigarette is composed of propylene glycol...", although taken in context, his statement does allow for the fact that other constituents are present (since otherwise the statement must be untrue).
Thus, until further research proves otherwise, strict adherence to published scientific opinion dictates that we consider exhaled vapor to comprise mainly of PG. A little leeway is probably acceptable though...

Basically - yes. There may well be some health implications but on the whole, it's going to be a lot safer than smoking. You might even find you catch less colds because that's about the single proven thing about inhaling PG. In the 1940's, several tests took place in which vaporized PG was introduced to the air in some hospital wards. Other wards were left without the PG.
Since, in a test period of one year, 5 infections took place in the PG-air wards and 100 in the non-PG wards, and other tests gave similar results, it was hypothesized that PG must have a both a bactericidal action and a virucidal action (many of the infections in the non-PG wards were simple colds, which are caused by a virus, so if that was prevented, it would appear that PG also has a virus-killing action).

If you were to vaporize PG or VG in a controlled zero moisture environment would the vapor be visible?
I'm guessing yes, because I think it is getting a lot, if not most of the moisture from your mouth and lungs.
I think I remember way back in science class that steam is water vapor.... I may be wrong though.
If so you can see that.
I was thinking more along the lines of a lab experiment bringing it to the vaporization point in an enclosed environment. But yeah lots of moisture being grabbed from the act of inhalation. Weird thing is if you hold the vapor in your lungs for a period of time the exhaled visible vapor is little to none.
