Although I agree with what you posted I think it is not alwys about kickbacks. I think the majority of the time Dr's get their information from a Pharmacutical rep who visits their office and leaves samples, telling the Dr how their latest greatest new drug will cure whatever better than the other Pharmacutical companies medication.
Probably true, much of the time. I know when I went for my asthma checkup in Dec, I asked for a prescription for Advair, to get my asthma back under control; he gave me the prescription, and also some samples to tide me over till I could get the prescription, but they weren't Advair, they were for a newer long-term asthma medication -- and they worked well, but I trust Advair more, since it's been on the market longer -- and hasn't been recalled for some weird side-effect. But I already know my doc has a brain in his head; he never gave me a bunch of grief about my smoking, because he knew it was a waste of time for both of us, and he reacted quite favorably to everything I had to say about e-cigs -- probably because THEY ACTUALLY WORK TO HELP YOU QUIT SMOKING, unlike all the other crap out there.
@ian-field -- I've heard good things about that mist, but I don't think it's available here -- guess the pharmaceutical company hasn't greased sufficient palms at the FDA.
