Sorry if I'm engaging in a forum 'faux pax' but I had a reply in a diff thread:http://www.quitsmokingmessageboard.com/viewtopic.php?f=12&t=38248&p=406333#p406549
that I figured would be good to copy/paste here, if we shouldn't do that moving forward (either the link or c/p, feel free to correct me).
My doctor, a small-town guy who is just about ready to retire (he delivered me and I'm pushing 35 to give you an idea), told me this:
"I don't really care what you do, just as long as you quit smoking the cigarettes". and further went on to say "If you get the soot and the smoke out of the equation, it will get the healing started". Asked me if I'd continue using the e-cigs once I'd gotten far enough away from the analogs, I told him I don't really know, with or without nic, maybe never? (being honest here). His answer to that: "Well, I've never smoked, so I've never spent money constantly on cigarettes, and I'm not sure how much this e-cig actually costs, but from what I've read (iterated the 4-5 ingredients), I can't exclude it as a way to get rid of smokes, ANYTHING to get you off the smokes". Then he held his hands up like Lady Justice with the scales and gave the standard common-sense retort: "If you are comparing SMOKE getting inhaled to your lungs" with (waves other hand) "nicotine vapor and some cake icing flavors, if that does it for you, I'm good with it".
I can quote this verbatim, since I saw him at his home this holiday weekend when I was visiting my grandmother.
There was also more banter about how much a "hobby" costs, and compared my continued use of an e-cig to his rock polishing hobby, which he has been doing for over 60 years. Has 3-4 polishers in his basement, and gives little bags of polished rocks to the over-3yo crowd at the office. I still have a bag from when I was a kid.
Doctors are practical around here in Iowa, they aren't on the "big pharma" payroll to a large extent (ok that was an over-generalization, but fits in my personal situation). Doc has watched over my hometown my entire life (and a decade or two before that) so he knows people that just won't quit smoking (and he knew I was one of those from past conversations).
