Some thing I found on the FDA and propylene glycol

ATSDR - Toxicological Profile: Propylene Glycol


CAS#: 57-55-6

This fact sheet answers the most frequently asked health questions about about propylene glycol. For more information, you may call the ATSDR Information Center at 1-888-422-8737. This fact sheet is one in a series of summaries about hazardous substances and their health effects. This information is important because this substance may harm you. The effects of exposure to any hazardous substance depend on the dose, the duration, how you are exposed, personal traits and habits, and whether other chemicals are present.

PG is a mild irritant. No more harmful to your body than drinking a hot cup of coffee.

If the FDA is so determined to eradicate electronic cigarettes on the basis of the fact that PG contains a mild irritant (VG, as an alternative is not) - then I'd like to hear their cognizant narrative on how tobacco proves to be a safer alternative.

In other words, we're living in an up side down world - hence, the economy fueled by corporate greed and gov't corruption.

The FDA can come up with a thousand reasons why they should have the prerogative over eCigs, and the ecig advocates can come up with a thousand other counter-claims on why it should remain a free enterprise initiative.

The rock gets tossed back and forth, and eventually someone throws in the towel.

What I get from the report is that as far as we know right now, propylene glycol is safe to vape. The inhalation studies seem to show either 'low' or 'no' serious side effects even after prolonged periods of extremely high exposure levels. Rats given oral doses for 2 years of at least 2500mg/kg (that translates into about 200ml of propylene glycol a day for a 175lb man) showed no negative respiratory or cardiovascular effects, and 10 times that amount were needed to create serious gastrointestinal effects. PG is in our foods, our medications (including asthma inhalers), and our cosmetics, so why worry about it being in our e-liquid? I'm not saying that it is harmless, since there isn't any real vaping research yet, but I would hate to have people become alarmed and anti-ecig over this, or try to use it as ammo to have e cigs banned. More and more doctors and scientists are saying that vaping is definitely safer than smoking and many, including my doctor, are recommending e cigs as a "safer" alternative. As far as I'm concerned, the pros of vaping greatly outweigh the cons. At the very least, I see my ecig as the 'lesser of 2 evils' when compared to the 30 marlboro's a day I used to smoke.

Here is a link to a thread on PG and its positive effects.

P.S. After the announcement of the findings of PG the FDA tried to push Vaporized PG in all public places. However, Due to the cost of vaporizing PG at that time it was not economically feasible.

Thanks for posting the link to that thread - it is absolutely fascinating, and also interesting to watch it progress from its start over 2 years ago.

Reading the effects on the PG is great but I think we need to also remember all the flavoring have not been tested to inhale. That's where we as a group need to be careful.

Courtesy of vapors club, here is just one study done by our Government on innocent Orphans back in the 1940's. Of course, this study was done when the Government wanted Prophylene Glycol approved. But some things never change! Our Government will stoop to any means to get what it wants passed, or banned.

This article is about a
study done (in the 1940's
since it is obviously
unethical to do before
they were aware of the
potential results!) where
PG vapors were emmitted
into a children's
convalescent home.
Quote from this article:
"The report of the 3 years' study of the clinical application of the
disinfection of air by glycol vapors in a children's convalescent home
showed a marked reduction in the number of acute respiratory infections
occurring in the wards treated with both propylene and triethylene glycols.
Whereas in the control wards 132 infections occurred during the course of
the three winters, there were only 13 such instances in the glycol wards
during the same period." http://www.ajph.org/cgi/reprint/36/4/390.pdf

It was definitely unethical to pump it into any public location to see the effects if the participants didn't know they were participating. Luckily, in this case the results were positive, and propylene glycol was shown to not only be safe, but beneficial...and that was the whole idea behind this thread...Is PG safe? Whether this govt, or any govt for that matter, will do things they shouldn't to produce a result they want is a totally different animal!!

I posted that to show 1) that our Government approved Prophylene Glycol many years ago. And 2), to show that our Government is not adverse to doing anything to approve or disapprove anything it wants to when they feel like it. I have a question for everyone! When the Government rans the tests on Njoy & smoking everywhere E-liquids, we know they claimed the "anti-freeze" component was in one test. Since this was not an independant study or test, just whom were the witnesses to the test? Not that the FDA would lie! hahaha! But this was propaganda at it's finest! The FDA has approved Prophylene Glycol in everything from toothpaste to albuterol. But because their good friend Johnson & Johnson is losing money, they now question Prophylene Glycol. Just saying.......

I agree with you 100% on that! I have no doubt that the anti e cig campaign is being fueled and financed by Big Pharma and Big Tobacco!! It's pretty sad that govt organizations, like the FDA, who are supposed to look out for our interests and our health, are actually being used as muscle for big corporations instead!!

Some good info here. keep it coming, I am still trying to find good info on VG as it really is not the same as PG has many different property's from what I am understanding. As I read I tend to question alot of the juices from some source's seeing most are really when you get down to it home-brews. Not saying there bad just saying i like to know more about what's really in them. What's in the flavors how do we really know?

Just something's that's been running through my mind. As some have left some really strange aftertaste.

Seems there might be a slight misunderstanding...the "anti-freeze" component the FDA found in one cartridge out of 19 tested was diethylene glycol, which is, indeed, some nasty stuff. However, the amount was approx. 1%, which would not be a toxic amount.
