I'm new as well. I've read "most" of the doctor's posts - and been quite impressed. I believe he is genuinely concerned with this issue. And also genuinely excited that we may have stumbled on the perfect harm-reduction nicotine delivery device. We tend to forget that physicians are prone to the same foibles as we mere mortals - including nicotine addiction. I personally know a gynecologist who, to his utter shame, is unable to rid himself of the vice of cigarette smoking. He is, otherwise, a most competent physician.
For me, I'm leaning away from e-cigs. My situation is a little different from most, in that I had been smoke-free for a year-and-a-half before picking up an e-cig. I was looking at nicotine as a last-ditch effort to address an episode of depression/anxiety. The nicotine has helped. NRT is not enough to have a therapeutic effect. Smoking just wasn't an option. I found that e-cigs and snus did the trick. Now, I'm leaning towards snus alone as my delivery system. E-cigs just have that problematic X-factor because of the lack of long-term studies. If, however, I were looking to break the analog habit (as most here seem to be,) then e-cigs would be the PERFECT vehicle. There is no doubt in my mind (largely do to Dr. Jim's research and the research of others here on the forum,) that e-cigs are far, far, far less hazardous than traditional cigarettes. But, again, there is that X factor, that question mark of what exactly is the long-term impact. With snus, that question has been answered by hundreds of years of Swedish use and plenty of scientific studies. So, since I don't have a "habit" (hand-to-mouth, visual feedback, etc) to break, why begin it anew?
But, on the other hand, them e-ciarettes sure are fun! And I like being a part of this community.
Lastly, I'll add here that my time with e-cigs has (I believe) caused me to have several episodes of unsightly teenage blemishes (the angry red kind that take a week or more to heal,) as well as given me a chronic cough. Even with that, I would choose e-cigs over traditionals in heartbeat. I hope this adds to the discussion. This forum is an invaluable tool, and you are all treasures. - Grant (now feeling sorry for having chosen such a silly screen name)
