How much PG is in the Ecig and how much would it take to cause harm within the human body

[Heca]

I have been smoking the ecig for about two months now and i cant really say anything bad about it besides having to charge it. I have not been coughing up phlem in the morning like i had been with regular cigarettes. I know that i am still inhaling nicotine but i can see that quiting will be alot easier after smoking the ecig. But the health concerns I have now make me want to just stay with some natural herbs.

I had came across this the other day and didnt really pay much attention to it untill i started reading on the forums. From what i can piece together there isnt really any details about the concentration of PG in the e-liquid and the preloaded cartridges. Also there is some type of absorbant material that holds the liquid in the cartridge form. I have not been able to find any details about what this absorbant material is. If anyone can shed some light on this im sure we all will sit a little easier puffing on our ecigs.

Here is the link where i found some numbers about the levels of PG but i cannot say for sure that there is this much PG to nicotine in what we are inhaling.

I think you'd actually have to pour PG into your lungs to get any kind of harm from it. The amount we use in vaping is pretty minimal, and the majority of it is expelled from your lungs as vapor when you exhale.

As far as the cartridge filler, it's polyfill, and can be bought in large bags cheaply at your local WalMart.

I would like to add to what Angus said by pointing out that wikipedia is perhaps the worste place to get info from as ANYONE can post anything there. Heck, I could post in wikipedia about theoretical physics, don't know the first thing about it, but I can still write about it in wiki. Also, it is common knowledge that PG is used in fog machines and many medical inhaler devices and itself is FDA approved. And the "filler" only makes contact with the bridge and does not actually get burned unless you puff on your e-cig heavily with no liquid in it.

P.S. I smell a troll. but it's ok, I fed him some facts so he shouldn't be hungry anymore.

Well, all I can say is that smoking e-cig is not that safe, but way safer than real cigarettes. You still have nicotine and "smoke" into your lungs but no tar nor tobacco baby!

There are currently several studies under way to evaluate the safety of e-cigs. As I recall, several studies were conducted back in the 50's and 60's in which monkeys were subjected to atmospheres saturated with with more pg than they could possibly absorb. Several interesting effects were noted: 1, the animals gained weight; 2, there was unilateral thickening of the respiratory epithelium which resulted in a thicker mucus layer across the tissue. This could potentially protect the tissue from opportunistic bacteria, however lung efficiency markedly decreases. These were extreme conditions however, and most studies being conducted now on e-cig safety are not focusing on pg. Various flavorings, other additives, and the vaporization of the poly fill are the prime suspects as of this moment.

pg & nicotine are the two most-studied (for inhalation), and least worrisome, ingredients in juice. If you aren't allergic or asthmatic, pg can be considered harmless. In most juices, pg is the main ingredient. Flavorings are usually between 10 and 20%, actual nicotine a tiny fraction, and the rest is pg & vg. You can tell how much if you know the pg/vg ratio. I vape at 70/30, so 70% of my juice is pg, ignoring flavorings.

The average vapor vapes about 3 ml a day, a percentage of that usually being PG. Vaporchef did some math and the amount of PG known to be harmful would be more than 1/3 gallon a day. I choose to vape mostly organic VG, but if I have the choice for anything to be more natural, less processed I will take it.
