Tom,
A fair question - I was just being lazy in not spending more time at the moment on this. I've been very busy with work lately.
But, here is some pertinent information showing the dangers of e-cigarettes:
From the Mayo Clinic, Dr. Lowell Dale, M.D. is the author:
http://www.mayoclinic.com/health/ele...rettes/AN02025
A New York Times article in 2009 detailed some of the risks:
http://www.nytimes.com/2009/07/23/he...fda.html?_r=3&
The most pertinent part (the bolding is mine):
" “We’re concerned about them because of what we know is in them and what we don’t know about how they affect the human body,” said Joshua Sharfstein, the F.D.A.’s principal commissioner.
The agency analyzed 19 varieties of cartridges, which hold the liquid, and two cigarettes, one manufactured by NJoy and another by Smoking Everywhere.
The analysis found that
several of the cartridges contained detectable levels of nitrosamines, tobacco-specific compounds known to cause cancer. One Smoking Everywhere cartridge was found to contain diethlyene glycol, a common ingredient in antifreeze that counterfeiters have substituted for glycerin in toothpaste, killing hundreds worldwide."
Much more recently, a June 27, 2013 article quotes the FDA's findings (the bolding is mine):
http://newsinfo.inquirer.net/434233/...f-e-cigarettes
"In a statement, the FDA said that e-cigarettes were not emission-free and that they contained “volatile organic substances,” like propylene glycol, and “carcinogenic” metals like nickel and chromium.
“The public, especially the youth sector, is advised not to start smoking at all and to stop using cigarettes, cigars, or e-cigarettes,” the FDA said.
“These ultra-fine liquid particles of less than 2.5 micrometer in diameter may penetrate deeply into the lungs …
second-hand exposure to e-cigarette emission, which may lead to adverse health effects, cannot be excluded,” it added.
The FDA said a study conducted by the German Cancer Research Center and the World Health Organization-Collaborating Centre for Tobacco Control showed that besides glycol, e-cigarette emissions also contained, nicotine, flavors, tobacco-specific nitrosamines, volatile organic compounds, acetone, form aldehyde, acetaldehyde, silicate and various metal particles.
“The particle size is between 100 and 600 nanometers, which is comparable to the particle size found in tobacco smoke of conventional cigarettes,” the FDA said.
“The levels of most harmful substances are lower in the e-cigarettes than in conventional cigarette smoke, but they do accumulate in indoor air,” it added.
The FDA said the study also showed that sodium, iron, aluminum, and nickel were present “at higher levels than with those known in cigarette smoke.”
“Five others, namely copper, magnesium, lead, chromium, manganese, were present in the same amount, while potassium and zinc were present at lower levels,” the agency said.
The FDA noted that nickel and chromium are carcinogenic or substances that might cause cancer while lead is suspected to be carcinogenic.
“If several people are using e-cigarettes in a room at the same time, considerable indoor air pollution will accumulate and may result to harmful second-hand exposure,” it said.
The agency said local government units should strengthen their ordinances against smoking in public places and on second-hand exposure to harmful substances."
Another article, which also mentions the concerns about e-cigarettes by the American Cancer Society:

Warnings have also been issued by the American Lung Association, as written about on May 30, 2013:
http://www.abc15.com/dpp/news/nation...g-some-say-yes
The World Health Organization has come out against them, as have other notable health groups and organizations.
Several countries, including Brazil, Canada, Panama, Singapore, Lebanon, and others, either ban e-cigarettes outright or limit their use to those places where regular cigarettes are allowed (generally, no public use).
States in this country such as New Jersey, California, and others do the same. All because of the risks involved, not just to the user, but to the genrel public through the dangers of second hand "vapor".
If the FDA, American Cancer Society, WHO, and other leading health organizations all say that e-cigarettes are dangerous, why should Maryland Live! risk its patrons health by allowing them?
Please do some more research. None of this is hard to find, or buried. There is lots more, including medical studies done in such countries as New Zealand and Germany by highly respected authorities, that also supports the dangers of e-cigarettes.
I could go on, but this should suffice. I've got to get back to work.
