I talked to my Doc the last time I went in and he was very excited about the whole e cig thing. Very supportive. Today I had to go back and took some of my stash with me. I vaped once and his jaw dropped!!!! I am definitely passing this on to my smoking patients, that is wonderful! I told him how I went from 2/3 a pack a day to the last 2 days nothing, but it is sold as replacement - NOT as a cessation device. I told him that even if the FDA finds 40 to the 4000 in cigs, I'm still better off, etc. and he was in total agreement with me! He even laughed that the FDA was against it! I left some cards I had from some different places I've ordered from lately for him to give out. I hope I helped, I certainly tried!
