I agree with you, but when you talk about E-smoking I dont think we are really talking about moderation. Especially those who are trying to quit smoking cigarettes. I hear most are inhaling it all day long.

But you're still only talking about a few mls a day.... even using 24/7! - ie not even a teaspoon full, and in many people's case, less than half a teaspoon full!
That is kind of misleading though. In terms of chemicals or vitamins or anything like that you are talking about small percentages, like milligrams. So when talking about chemicals when you say you are consuming 2,000 plus milligrams of it a day, that is considered substantial. And that is just the liquid measurement, You have to take in account the volume of vapor you are inhaling. for example, imagine swallowing a teaspoon of pure nicotine? or 2,000 mgs of nicotine??
You'd be dead. Also- we aren't supposed to be adding stuff to our nic- it specifically says that when you order from a factory. If adding anything to it makes you nervous, then don't do it? Just inhale water vapor and chew some nic gum. No one with any sense in their head is claiming PVs are 100% safe, but general masses agree, they are safer based on a very simple logic...less chemicals (like 3980 or so less) and no known carcinogins.
I go through a 10ml 36mg bottle in 2.5 to 3 days and I don't think I'm any crazier/sicker than I was before. In fact now that I'm not smoking two packs of camel unfiltered a day I feel fantastic. So...I have issues with moderation but will maybe be a good test subject as it's been about six months now. I'm now sick and hacking my lungs out but I still feel soooo much better than I did before when I used to get pneumonia every single stinking year. I'm pretty certain this isn't e-cig related. You may wanna PM me every few weeks to see to see if I respond and I'll let you know if I start glowing in the dark or anything 
Angela, i know we are not obviously. I was just trying to make a point about measurements. A teaspoon full seems like nothing, but depending on what your talking about makes all the difference.
but i guess you all make good common sense arguments.

Digest:
NASA is planning to use PG-based coolant for the Orion crew exploration vehicle, which is part of the Constellation Program to send human explorers back to the moon and onward to Mars and other destinations in the solar system.
The purpose of this document is to review the existing inhalation toxicology literature on PG and develop maximum acceptable air concentrations for 1 h, 24 h, 7 d, 30 d, 180 d, and 1,000 d of potential exposure to vapors of PG.

Caveat - need a PHD in Biochemistry to decode
It does look promising for PG, too bad for me it makes me feel weird.
VG is the one that may cause kindey problems..easy to google that one.

You need to read more posts on the forum. Tropical Bob and Kate have post the same studies and information on the forum in lots of different places. There is lots of information on PG if you really look for it. Don't take other peoples word for it look PG up yourself.
Makes sense to me, too. And it's in analogs, so before e-cigs we were all already inhaling small amounts of it every day.

Thanks for that, I couldn't find it. Now to clarify: we did not vaporize it before it went were it was supposed to.
Just in case I want to make sure my yings-and-yangs are covered here.

Mpetra, go read the "germ-killing vapor" thread. Read Dr. Laugesen's final report from Health New Zealand. There is NOTHING scary about inhaling PG. Quite the contrary. It might be a benefit to your health! It has been tested and tested and tested ad nauseum, with rats and primates and children and grown people .... This is not some new and scary chemical with unknown effects.
P.S. Thanks Taz. I flew over the keyboard after that post and before reading your reasoned answer ....

I have read (I think) most of the items pertaining to the danger/non danger of PG. I not worried, just a bit uneasy, but nowhere near as uneasy as I am about all the garbage I was smoking in regular menthol cigs.
So I will continue to vape, thats for sure (I was a chainsmoker and am now down to only a few regular cigs a day) I hope I can keep up the vaping and do away with analogs completely.
Tbob , thanks for sending people in the right direction. I can never remember where I left those good threads. We seem to have quite a few (too many) threads started bashing PG.
Another thing that might help reduce worry about propylene glycol is that it's used to administer medication to lung transplant patients (so it's considered safe enough for medics to use on very vulnerable people) - PG is considered safe for inhalation by lung transplant patients
Does anyone have any information about quantity and duration of using PG? I dont think my concern with PG is its toxicity of short term use, I dont think i am going to puff the ecig and die of PG poisoning. But Im more curious about how the body has to dispose of the PG in significant quantities over time.
For example. Lets say PG does not pose any significant risks to your lungs with moderate intake, but PG puts a strain on your kidneys to remove. Obviously someone only taking in a little bit of PG into their lungs for medication purposes wont have much trouble disposing of it. So its insignificant and deemed safe for these people. Same way if beer was a medication for someone, If they drank a cup or two a day there would be no risk to your liver. But what about duration and quantity. If i drank beer all day long for years, the results would be different. I am sure none of these studies are talking about taking 2,000 mgs or more a day of PG continuously for years.
So i guess my question is are there any studies that talk about concentrated PG exposure in significant quantities, 2+mls a day for a long period of time?

If you actualy read this, and if wanted follow the link to the original studies, you will also find long-term inhaling (of a lot!)
But if you remain this anxious with vaping, then perhaps other alternatives are really better for you...
