Adverse Effects on Respiratory Health?

[ACM]

Here's a bit of worrisome information I came across while trying to get more info on the safety of inhaling propylene glycol. I know it's FDA approved as an ingestible substance, but it was never tested as an inhalant. One of the main arguments people cite about the safety of e-smoking is that PG is used in theatrical smoke machines. Well, as stated in this article, that may be a flawed argument.

(I would have posted this in the Health forum, but as a newbie, I can't):

Adverse Effects on Respiratory Health (from smokemachine.eu)

"Although often believed to be safe to breathe, exposure to mineral oil, glycol and glycerin-based theatrical fogs produced from fog or haze machines have been associated with adverse short and long-term effects on respiratory health in exposed performers and crew members, especially those with respiratory problems (such as asthma). One should therefore avoid breathing generated smoke or fog.

"It is safer to add smoke effects digitally in postproduction of films than to use theatrical smokes on set. Glycol-based fog is associated with headaches, dizziness, drowsiness and tiredness in those exposed. These results would be expected given that glycols share some chemical similarities to alcohols and given the small size of fog particles making it easy for them to enter the bloodstream. Symptoms of wheezing and chest tightness were associated with longterm exposure to theatrical smoke and fogs."

Any comments?

so does normal breathing in a city......



And i don´t know the exact article but a research has already been done.. i think new zealand did one. And it showed no problems. I wouldn´t trust the FDA if i was you. It´s all a money thing...

You didn't really think it was entirely safe did you? I mean, you are inhaling something that, let's face it, your lungs were not meant to be processing on a regular basis. I would expect there to be some adverse effects of the PG or VG or w/e you put in your lungs that isn't fresh pure air.

The thing for me is, it's gotta be better than cigarette smoke...gotta be. So I'm ok with the trade-off and the calculated risk that the vapor from an e-cig won't be worse for me than the smoke from an analog. It's a choice we all make, but I don't buy into the hype that e-cigs are 110% safe to use.

Now for the other side of the fence:
I wouldn't be surprised to find out there's more than just pure pharmaceutical grade PG in that fog juice either....just saying. Also, those fog machines output just a tad more vapor than our PVs do right? When a fog machine is used, it can fill a room with it's vapor. That kind of exposure is a little different than even regular puffing off a PV. Odds are good that in between puffs, you're getting some regular old fresh air into your lungs. If you are in a room with a fog machine, you can't get any "fresh" air.

Longterm effects of PG or VG inhalation? We'll find out in about 10 years or so I guess.

There is an Industrial or Commercial grade PG. That is what is used in the fog machines. Sorry, I cannot cite the source.

But as mentioned, I would rather vape PG or VG daily for the rest of my life (and probably will) than the contents of analogs.

I have to agree that the concentration of PG emitted from a fog machine must be more that in an e-cig, and the volume alone must account for much of the concern. One thing that struck me about the article was that it referred to respiratory distress in people with respiratory problems already, such as asthma. I wonder how it affects people with no problems.

I have only been vaping for slightly more than a week, but I must say, I already feel better then when I was smoking. Smoke is much more of an irritant to your respiratory system than PG vaper.

By the way, please see my post in the thread about the Prevent All Cigarette Trafficking Act of 2009. I can't post the link, but it's an important issue. Try to pass the word to get as many people as possible to write to their U.S. Senators. This law MUST die in the Senate. If it passes, it will mean the end of e-cigs in the U.S.

I have been vaping 20ml or so pg liquid a week for over a year.

2 weeks after I started vaping I stopped coughing up a sheet load of lumpy yellow flem and gunk in the morning .

Blood pressure tested every 3 months is normal, No tight chest or wheezing and I was wheezing before I started vaping.

My conclusion so far I breathe easier and feel better .

One more thing if pg is bad why do they put it in inhailers for asthmatics and its been there for years.

 

[flrailroader]

All i can say is for me its been 7 days of vaping now and i feel better than i have for as long as i can remember(2 packs a day for almost 30 years) took 2 inhalers a day until 2 days ago.My breathing has dramatically improved almost immediatly after i started vaping,and for the last 2 days i've been going 6v on 24 mg almost steady and feel no side effects at all . So if PG is that bad for me i think i can live with it.

I was just going to suggest the OP Google "nebulizer asthma propylene glycol" and see if the results didn't make him feel better.

If there were a danger in inhaling propylene glycol, asthma medication would be the *last* place it would be used.

Any comments?

Yeah I have a comment.
I work in the Theatrical/Entertainment business. Ive been doing it for over 20 years (12 years as an Entertainer, 8 years as a Technician).
I am exposed to Theatrical Fog/Smoke (mineral oil, propylene glycol and glycerin based) at least 2-3 times a week.
I have never experienced any adverse affects (other than the dry scratchy throat which is common and easily remedied by drinking water). I have also never known anyone else that has had any adverse affects.
Now I do suppose that someone with Respiratory problems (IE. asthma, bronchitis, emphysema, etc) would probably have issues breathing Theatrical Fog/Smoke, but then again people with those conditions have problems during allergy season or when the wind blows and kicks up dust.

Sorry, but you are wrong.
The PG in Theatrical Fog Juice is USP and there are even labels on the jugs/bottles that state to that fact.

Here's one of the results I obtained from using Google:

Danger of Inhaling Propylene Glycol | eHow.com

As you can see, propylene glycol is considered safe and has even been used in medications for asthma.

Guess the anti's will have to rewrite history and references if they're going to try a disinformation campaign.

Here is one link about propylene glycol http://www.e-cigarette-forum.com/fo...07-reality-pg.html?highlight=propylene+glycol

I find it very interesting reading and I think you will too!!

If you are in a room with a fog machine, you can't get any "fresh" air.

I have been in a room with a Fog Machine that was putting out 30,000CFPM and the fog was so thick I couldnt see my hand in front of my face.
Yet I had no problem what-so-ever breathing.
Talk some more about something you know nothing about.
Much like the FDA.

I'm not the OP, but it does make me feel a lot better. I've wondered about inhaling this stuff too, but if it's in asthma inhalers, thats good enough for me.
