Exhaling 99% Water Vapor?

Like The Fog said...and...

PG is on the safe list for use by the FDA - for whatever that is worth. In my view that has literally no value of any kind. The only issue is our use of it. It is used on food, cosmetics, etc. etc.

While there is a possibility that vaporizing it could have negative consequences, if truly safe, i find this unlikely. To change the properties of a compound requires something like significant heat, for example. Therefore, it seems to me that the odds of actually changing the properties of it with minor heat by a tiny battery to be extremely small. Even if used in cosmetics (which you already use) it absorbs into the body. Any discussion of whether you believe PG is safe to vape begins and ends whether you believe the FDA on what they consider safe. Personally, I find their opinions are at least debatable, at best.

I have no idea what the hell you just said... LOL.

I personally haven't yet found any reason to be concerned health-wise, but I do intend to keep an eye on this side of things.

Great thread!

Significant Heat? Atomizers super heat the liquid and that is how we get vapor instead of steam.

Again, I damn sure am not a chemist, lol. What i mean by significant heat to change a compound is vaporizing a compound to CHANGE it's physical properties. That would take ENORMOUS heat...

For instance, you can vaporize Teflon, as mentioned earlier. But it requires a lot of heat to do so...Once vaporized it is extremely toxic, by all accounts.

What i mean is this. If you vaporize H2O - it still remains H2O - regardless. It is still H2O. However, my understanding is that you CAN change the properties of things if you apply a LARGE amount of heat to them. it is not same...

But again, this is WAYYYYY above my head.

It has been used, as an inhalent, for over 40 years. It's been proven safe, the only question of safety would be from the other things we're putting in it, IE the chemicals in flavorings.

Check out the links I posted earlier, a lot of information from actual studies in there.

There you have it - from someone that knows...My thoughts were educated guesses based on simple logic...

Here is the deal with PG: It's a humectant, which means it attracts water. It is soluble with water, so they mix in liquid form

As PG molecules separate (when they shift from liquid to gaseous state from heat, like when you vape), the individual molecules attract water molecules from the surrounding area and bond together. This is happening from the vaped water in the e-liquid, in your lungs (full of water), the air in your mouth, and outside as you exhale. gaseous water molecules rush to the PG, and make big balls if you will, enough to refract light (tiny tiny liquid-state droplets) and are visible as "smoke", or visible vapor.

You're probably exhaling most of the "atomized" PG accosted with H20 molecules from the juice, along with some of the flavor and nicotine not absorbed by your lungs, but it's hard to say how much. This is why some of the FDA studies are suggesting that 0-18mg nic-PG mixes are notoriously unreliable for how much actual nic you get in a draw. Hard to say how much is actually completely atomized and absorbed, vs. exhaled.

If you want to claim 99% water vapor, it's because there is an enormous amount of water molecules bonding to the vapor PG. It's impossible to say how much is actually coming from the water in the liquid mix, your wet lungs, mouth, and surrounding air.

Whether or not any remaining PG from the vape sits in your lungs, and is even harmful, is up to debate. There are only a handful of legitimate studies using aerosol PG and oral inhalation on primates. Still, they all conclude no significant toxicity.

Thank you all that contributed to this thread. It helped me to understand why people say we exhale water vapor, even though that is a bit missleading as it is actually water chemically bonded to PG that we are exhaling.

I have wondered this for a while, seeing as i do not see water listed on the labels i have on my E-Juce bottles.

Of course, i am a bit saddened that there arent any tests available for a difinitive answer. Or, at least i cant find any.
