I to have never liked the chat feature, I also prefer this style. I find it easier to interact with customers this way.
To preface this, I am stating right off the bat that I am strongly libertarian and believe in adults rights to eat and consume what they wish without undue government interference; that will affect my views...which I know are unlike the other Expert who answered you before.
There is no question in my mind that the e-cigarette, while not a paragon of healthy living by any means, is far safer than conventional cigarettes. Conventional cigarettes have over 1,000 different chemicals, many of them known to be carcinogens, like formaldehyde and tar. The e-cigarette only has nicotine and thus has only the dangers of nicotine. So, on that basis alone there is less danger as there are far fewer toxic substances. The only identified one being nicotine.
That is, of course, if your e-cigarette is made in the USA. If it is made in other nations who have less stringent safety standards than we do, there is a chance of other chemical contamination. Also, the FDA thinks that the e-cigarattes vapor "may"
have some trace chemicals that may be toxic. However, these same chemicals have been found in nicotine chewing gum, and in the nicotine patch. Actual cigarettes have chemicals KNOWN
to be toxic.
Reason Magazine, a libertarian site has written many articles about the FDA's...in their view...misguided response to the e-cigarette: http://reason.com/archives/2011/11/17/the-fda-kills-smokers
is a terrific read for more information, along with physician quotes saying that the e-cigarettes can save lives by reducing actual cigarette use and studies show that.
I hope that was helpful, and good luck in your efforts to quit.
