I just got home from my routine check-up with my family doctor and during the exam I mentioned that I had almost quit smoking cigarettes. He asked me how many I smoked and how many I was still smoking. I replied that I was up to 2 packs a day and during the first week I dropped that to 10 per day, a 75% reduction with no cravings. I told him that I had just ended the 2nd week and was down to 5 a day, still with no withdrawal symptoms and explained that my lungs were clearer than they have been since I was a teenager, which he confirmed by listening to my heart and lungs with a stethoscope.
He asked me how I had quit and I explained E-cigs. He had heard of them, but had not seen one. I showed mine to him and explained how it worked, that it used PG or VG as a vapor producer and carrier of the nicotine. I explained how the vapor was produced and that the PG was used in asthma inhalers, intravenous drugs, and mentioned several foods that contained PG and that it was GRAS (generally regarded as safe) by the FDA. I told him where he could get more info from Google and mentioned that I was using 24mg liquid and planned to titrate down to 18mg then 12mg and eventually 0mg nicotine over time.
He was impressed and agreed that a carrier used in asthma inhalers shouldn't be dangerous when used as a nicotine carrier and applauded me for quitting and said that he thought that the E-cig idea was a good one. He did encourage me to taper down the nicotine gradually and get to the 0 level because of the blood pressure benefits.
I asked him if he would like a demonstration and he said yes. I puffed a few times and blew a stream of RY4 into the examining room! His eyes got a little wider and I asked him if he smelled tobacco smoke. He said, "No, in fact I don't really smell anything from that. It's surprising, considering the smoke you blew out!" I explained that it was not smoke, but PG vapor, much like the theatrical stage fog that has been used for over 40 years.
The bottom line was that he now has had a good demonstration and I think that he will research E-cigs and is likely to mention them as an option for patients looking for a reliable quit method.
