That was my answer too Mac, while there is mist exhaled, the chart below is from the October 2008 results of
The harmful effects from VG or PG is non-existent. In fact the anti-bacterial properties of both would negate any cause for harm.


Three experiments were undertaken, as follows:

1. 38 millilitre puff. After correcting for dilution, the most common cigarette smoke
toxicants were found to be either completely absent, or present in amounts less than 1
part per million. The LED at the tip of the e-cigarette was activated, indicating air was
pulled through the e-cigarette. The mean results from analysis of duplicate samples were as
follows:

Table 3.1.2 Compounds measured in first 38 ml sample of e-cigarette mist.
Compound Mean Units

1,3-butadiene not detected Ppm
Acetaldehyde 0.34 Ppm
Acetone 0.16 Ppm
Acrolein not detected Ppm
Acrylonitrile not detected Ppm
Benzene not detected Ppm
Ethanol 100 Ppm
Ethylene glycol not detected Ppm
Ethylene oxide not detected Ppm
Formaldehyde 0.25 Ppm
Hydrogen cyanide not detected Ppm
Cresol 0.16 Ppm
Xylene 0.18 Ppm
Nicotine not detected Ppm
Propylene glycol 32 Ppm
Propylene oxide not detected Ppm
Styrene 0.29 Ppm
Note: The limit of detection was 0.01 ppm and the limit of quantification was 0.025 ppm
for this analysis.

2. 58 milliliter puff. Analysis revealed that the concentration of propylene glycol was too
high for the SIFT-MS instrument, so a subsequent dilution was made bringing the overall
dilution to 1 part puff in 1500 parts air. The results obtained revealed a concentration of
approximately 0.5% propylene glycol (5000 ppm) in the original puff, but did not allow theresearchers to gain any reliable quantitative data for the toxicants.

So all in all, your baby is blessed to have a Daddy who is doing a really great thing for everyone!!​

Because inhaled nicotine is over 98% absorbed6, the exhaled ‘smoke’ is propylene glycol
minus the nicotine, and any exhaled PG mist dissipates within seconds. Without the
gaseous products of combustion, the ‘smoke’ is not harmful to bystanders. The ‘smoke’
or mist is not tobacco smoke, and not from combustion – no flame is lit – and is not
defined as environmental tobacco smoke. and e-cigarette “smoking” would be permitted
under New Zealand’s Smoke free Environments Act31.

this is from NZ`s report: http://www.healthnz.co.nz/2ndSafetyReport_9Apr08.pdf

All up in your grill..
I'd love to see an explanation of how one's lungs or airway mucous membranes are supposedly able to extract 98% of the nicotine and leave the vapor to be exhaled. I'm really having a hard time buying that.
that's not what we are saying. What we are saying is that vapor doesn't behave like smoke. Try it for your self. Blow a big puff of vapor out and count how many seconds before it's gone. Should be about 5-8. Real smoke hangs in the air for hours.

Kate, is the FDA simply ignoring this report from New Zealand simply because it wasn't done by them? It sounds pretty thoroughly tested, in a way that would make anybody understand the effects of e-cigs and it's mass health effects in contrast to traditional tobacco cigs.
Seems that way, doesn't it!! Ruyan paid dearly for that testing, I'm so glad they were able to succeed to the point they have. NZ is in the grip of the no-smoking vise (as is the rest of the world), because of Anti-Smoking-Activist groups. I feel the testing was immensely important to us all. But a quirky thing happened: New Zealand Health defended their position against our FDA's position. It was wonderful!!
The Dekang co in China is also gearing for FDA approval, they market most of the world's e-liquids (90%, according to their Website). I believe Ruyan will also, these are really the only entities in the world who would possibly have the financial punch to be able to afford it. To my mind the FDA is way overboard on their ability to be able to 'weed out' the small guy trying to gain access to the market. It's all about money, and that's just wrong, but that's the way it is. It shouldn't cost Billions of dollars and years of 'political' pandering to see that a new technology is ok for distribution. Big Pharm and Big Tobacco have seen to that, as well. WHO, ASH, and a host of others also have their many legs in the pot as well, very daunting.
I say, slap on a "use at your own risk" tag on e-cigs, just like they do with so-called miracle drugs and chemically-created cigarettes, they always have the option of removing them from the market if harm is done.
People can still buy cigarettes all around the world on every street corner. Go figure. Good source of Tax Revenue? They are also aware People die from them.
Many times FDA 'approved' something that perhaps wasn't clinically acceptable in long-term use. More People die. However just watch some info TV late at night, there are many potions for sale that have no FDA stamp. When they're caught they change the name and re-advertise. Same stuff, different day.
Our System needs big-time overhauling. Don't hold your breath on that one.
