There is really no evidence of one or the other being mortally dangerous when inhaled at the temperatures we inhale them.

This is a delicate subject because there are many who have zero doubt that vaping is 100% completely safe and thus they should be treated as so (i.e. have the ability to vape whenever and where ever they'd please). But, there is really no concrete study showing the effects of vaping in a long term stance.

That being said, as I had previously noted, there has been zero findings of vaping being mortally dangerous in any way.

PG, VG, it's a matter of preference or if you're sensitive to one or the other (I'm personally PG sensitive. I can vape it, but not all day or for long periods of time. Else it causes discomfort.)

At this point, we're all just lab rats to a greater cause (I hope :) )

I have always stuck to VG because i heard that PG Is not very good for you, is this true?

While I completely concur with Levitas' statement about us being test subjects, I'd seriously have to take major clues from the fact that the pharmaceutical companies have used PG in inhalers for years, and that many hospitals inject it into the air for virucidal purposes as a MAJOR clue that you were told wrong.

thanks guys makes me more comfatble about buying it now as there is one flavour i want but only in PG

You might grab some VG to mix in with it. That way you don't have to sacrifice vapor production...just an idea. You can get it at most pharmacies and even Wal Mart (they do have Wal Marts there don't they?) Just be sure the label says 99.5% Glycerine with no other added chemicals.

Perhaps there are no long term studies on the effects of something called "vaping", but there are studies that go back to the 1940s on the exposure to PG vapor in industrial setting. That's when they started using PG based coolants in machining. No ill effects were ever found.
I conducted a 30 year non-scientific study on this myself by working in three different GM plants before I retired. My results are tainted, however, by the fact that I was smoking that entire time but since I've only been inhaling PG and VG for the last year and a half I can run quite a ways without getting winded and I'm going on 15 to 20 mile bike rides and I'm 53 years old and about 20 pounds overweight.

I came across a study done by a company that was condensed that long exposure to PG via fog machines was not harmful to their actors. They found there was no health issues for people who were exposed to it for long periods of time. Also I think I seen the LD/50 and toxicology report for rats and rabbits and it was some outrageous amount of PG to do any harm to the animals. I wish I could remember where I saw that. It might be here on ECF somewhere. That is just my 2 cents.

Forgot to put a very well placed "not" totally changed what I tired to say. Sometimes my brain dont think so good.

I use VG exclusively (ECOpure) because PG causes my throat to become tight. This is an effect many PV users have noticed. VG is easier on my system, but as others have pointed out, we don't really know for sure what the long term effects of exposure to it are.

That said, if blood work is any indication using a PV in general is a huge health benefit. My blood work was all crazy, particularly in terms of triglycerides until I quit analogues and went to a PV. Now my blood work is normal across the board. Miracle.

Though we have yet to see long term medical trials, both of the doctors I see regularly agree that using a PV is far better than smoking and strongly encourage it. They both feel that the best plan is to decrease the nicotine content in the liquid over time and eventually stop vamping too, but they're not in the least bit concerned about my choice to continue using the same level of nicotine for the indefinite future.

Purely anecdotal, but perhaps helpful?
 
PG is much better understood as safe for inhaling, and is heat stable; it is also anti-microbial. With the caveat that some people say it doesn't suit them, PG is, imo, the best option. VG is not heat stable and long-term inhalation safety is pretty much unknown. I think it is ok to use it up to say 20%, but beyond that I have doubts; though if it's 100% VG or analogs, use the VG, no contest.

Three issues with VG : 1) (primary issue) heat decomposition 2) very slow evaporation (how well it is absorbed in the lung I don't know) 3) (indirect) when at a high %, the liquid is viscous and doesn't wick so fast which can lead to more incidence of filler burning.

I started using 100% VG, until I noticed it left an oily film on my windshield. I have since changed to at least a 50/50 to all PG. No more oily film on my windshield. I didn't want the oily residue to be in my lungs.
My understanding is while PG and VG can have a slick oily feeling it is not oil. There is no oil itself in e-juice. I understand the body can easily break down and process PG and VG where it cannot do so with real oil.

I read someone else's post though that stated they had an oily film on their windshield. I have vaped like mad in my car with the windows shut...no oily film at all.

Well said. The more I read about the differences between PG and VG. It seems that PG is the better choice out of the two. Although, I mostly vape high PG juices anyways. Glad I'm not allergic to it.
