Dubious claims re:"water vapor"

[Tgoode]

I have seen a number of websites and YouTube vids that claim that vaporizers produce water vapor. Since our PVs are boiling PG or VG, it is only logical that they produce PG or VG vapor. The only way to get water is to burn the juice (read open flame) or heat it to the point where the chemical bonds break. Even then you would get lactic acid, oxalic acid, and other decomposition products.

So, ecigs don't produce water vapor.

Discuss...

From what I understand, the PG (and maybe the VG too) absorb water from your mouth/airways and the air, so that much of it actually IS water vapor. I'd imagine it's not 100% water vapor though. I've read that most of the nicotine gets absorbed, but personally I don't buy that. I think there has to be an appreciable amount of nicotine if you exhale a big plume of vapor. If you stealth vape (hold it in until there's almost no vapor to exhale) IMO more nicotine would be absorbed, or at least not exhaled.

JMO...

PG and VG absorb water from the air and from our bodies ...to such an extent that it is a fairly large % of water vapor. Now, to be fair to your intelligent post I think it is a condensate.... PG/VG/nic-extract/flavor/water. Not 100% water vapor.

If you say "condensate" to the average Joe, his eyes glaze over. So it is a simple, but not 100% accurate, expediency to say "water vapor"... like FOG. It gets the point across that IT IS NOT SMOKE!

Also, I think there are some scientific reports of what exactly is exhaled (with a particular e-cig in a laboratory setting, etc...), but I don't have them bookmarked so I can't find them easily.

Even thought you aren't vaporizing a significant amount of water both pg and vg attract water from your lungs and air. Vg usually has about ten percent water to thin it out. So when you exhale the vapor what you see is actually water vapor combined with pg and vg.

While it might be expedient to say "water vapor", I don't think it's really honest. If I'm trying to convince someone that the stuff I'm exhaling is safe and I tell them, "It's just water vapor", then I am (probably) lying to them just to make my life more convenient.

An appreciable amount of nicotine is destroyed during the vaporization process. We exhale little if any nicotine. When vaping, we must take in many more puffs than we would of an analog to get a comparable amount of nicotine.

Do you have a reference for that AG? Thanks!

We are vaping at a much higher temperature than what nicotine can tolerate.
Much like a cigarette, not all is destroyed, but a lot of it is....

Nicotine - Wikipedia, the free encyclopedia

"Nicotine is a hygroscopic, oily liquid that is miscible with water in its base form. As a nitrogenous base, nicotine forms salts with acids that are usually solid and water soluble. Nicotine easily penetrates the skin. As shown by the physical data, free base nicotine will burn at a temperature below its boiling point, and its vapors will combust at 308 K (35 °C; 95 °F) in air despite a low vapor pressure. Because of this, most of the nicotine is burned when a cigarette is smoked; however, enough is inhaled to cause pharmacological effects."

...there is a lot of info in the research/health/safety sections of this forum BUT, it appears many studies are flawed(there are some good ones)...in my readings, the only thing that stood out is 66%water vapor and the rest is a toss up and even that study was severely flawed in HOW they used the ecig(vertically, batt end straight up in the air)...the hard truth is, we are the lab rat in an ongoing, unsupervised study........

yehap it is mostly water vapor

Perhaps I should have been more speific... What I meant to say is they don't produce 100% water vapor. I would doubt the water content would be more than 30% of the vapor that comes out of the PV. I will concede that what comes out of you when exhaled probably contais more water however.

Flavor Art is doing some testing of their juice flavorings that looks interesting.

You can say what you see is water vapor combined pg/vg. If you want to be more accurate tell them what is in the juice.

When we say we exhale carbon dioxide that doesn't take into account various other gasses we exhale either, include water vapor. Does that 1-2% make you a liar?

never mind

My line has been, "Its more like stage fog then steam." Ususally enough for people to understand.

So that's why I'm having sudden cravings for cheese. I thought it was my taste buds coming back...

Thanks! That makes me want to buy some FlavourArt !

It's pretty propeller head stuff, but at least they are testing.
