I responded to the writer:
I smoked a pack a day for 38 years. I tried quitting cold turkey, tried patches, gum, hypnosis, everything but Chantix. None were effective for very long. Sooner or later, I visited the convenience store and purchased another $7.00 pack of smokes. Out of desperation, I bought a "personal vaporizer." I took one puff on my "PV," and threw most of a pack of cigarettes in the trash. That was on December 9, 2009. I have had no - none, zero - urges to light up a cigarette as the electronic version mimics the act of smoking to a tee, including nicotine delivery, minus the dangerous chemicals and combustion by-products of tobacco. I would suggest that, rather than rely solely on scientific studies (University of Virginia... isn't that the same state where Phillip Morris has its headquarters?), you talk to as many "vapers" as you can find. Their stories will be very similar to my own. As far as I'm concerned, I'm an ex-smoker and, as long as I have my "e-cigs," will remain one.
