The appointment went well, but it not seem like the doc knew much about the product, if anything. This slightly surprised me. He consulted some sources (seemed like a Doctor's wiki), and the conclusion he reached was that they are definitely safer than cigarettes, but not the ideal solution of being off nicotine altogether. He told me he was going to look into it more. I showed him the PV (didn't puff) and the ingredients of the juice.
He was totally supportive and complimentary of me for getting off cigarettes, and said he would look into local pulmonologists who might have more experience with the product. I gave him some sources to check.
