I spoke to a well respected pulmonologist in Central georgia last night at work. He had given me a RX for Chantix a few years ago, and I told him I had been off analogs since may 2011 with the aid of ecigs, and he stated that he refers all his hard cases who will not quit smoking to these devices. He was very supportive of ecigs and stated it was the best smoking cessation device he has EVER seen. This guy is a Critical Care specialist, and has been doing it for a long time. He stated it was perfectly safe in his opinion. I had already felt this to be true, and evidence that I had seen to this point internally and externally pointed to this, but it was great to hear ir from someone whom I have so much respect for.
