Bob, I quoted a doctor of pulmonary medicine almost word for word from here:
YouTube - What The Dr Says About Electronic Smoking
A PHD, pulmonologist and a practicing physician for over 20 years, he is also a spokesman for the e-cigarette industry endorsing the Smoke51 product who's reviewed the studies.
Phrasing issues can make the interpretation of comments on these often complicated matters somewhat tricky. The last statement about the FDA I had clearly worded wrongly, owing mainly to the necessity of addressing the content of nicotine. It should say something like: The harmless vapor produced by the product, as determined by laboratory tests, contains 99% water, 1% nicotine and trace elements that have been deemed non-harmful by the FDA.
So I did a couple of corrections and resubmitted it. Doubtless there are still errors and omissions. But seriously, do you really think they're going to publish it? The only specific concern I've heard about, besides the possibility of inevitable impurities that derive from the nicotine extraction process in the otherwise pure nicotine additive is, that the vapor may contain traces of acetaldehyde. It seems to me that half a thimble full of vodka would be likely to produce more of the same toxin in a person's body (as a byproduct of alcohol metabolism), or possibly we could get the same amount from using a mouthwash, even after rinsing. What other concerns are others aware of?
Anyway here's the correction:
[If the electronic cigarette is shown to be much safer than smoking, it seems more ethical to me to keep an open mind concerning the beneficial uses it has rather than to demonize it which is how your review reads to me, and the position statements of WHO appear to me to amount to an attack. Warfarin killed my mother, but doctors who pledge to do no harm endorse it. The same "potentially toxic" additives that are referred to by WHO in the US News report are found in nicotine patches, and the only other additives are propylene glycol and a little flavoring which are non-toxic. That's it. And safety studies have been done. Certainly WHO needed to make a response if a false claim of endorsement were made. But it thus appears to me that their response is retaliatory and slanted against the entire industry because of an isolated incident, which would certainly be unethical on their part. I have not personally heard of these being marketed as a smoking cessation product and yes, another battery of studies would need to be done to make that claim. False claims are the basis for two thirds of the complaints by WHO and seems to be nothing more than a smoke screen. Now I've covered all of the points they make against them. But again, about safety: the electronic cigarette does not contain any of the 4000 plus carcinogens found in regular cigarettes. They contain no carcinogens, there is no second-hand smoke and they do not cause cancer. The harmless vapor produced by the product, as determined by laboratory tests, contains 99% water, 1% nicotine and trace elements that have been deemed non-harmful by the FDA.]
