I asked my doctor this last week.
I live in a podunk town in the middle of nowhere, but we happen to have very good medical personnel here.
My internist was thrilled, and I mean thrilled, that I am 8 months off analogs. I even prodded him with "well, we don't know for sure about flavorings, etc........." and he just shook his head and said "NOTHING IS AS BAD AS SMOKING CIGARETTES.........NOTHING. Keep vaping."
I also asked my gastroenterologist and he said "great! Next time we do your scope I'm sure your esophagus will look better."
Hey look there are no guarantees.........but we do know that the cellular damage done by cigarettes is rather incomparable to just about anything else you could "do" to yourself. Really. It's because of the combustible nature of smoking. Do the research on exactly WHY smoking kills, and you will start to see this.
vaping is harm reduction, at least until we have proved it is totally safe. Right now, eating deli meat has been proved not totally safe for instnace, nitrates have been postiively implicated in cancers.......but not many people die directly from eating processed deli ham, compared to the amount of woe, destruction and absolute harm that smoking has wreaked on the human population of smokers.
Hey, if you can quit analogs cold turkey, great. I tried that twice and during the window of time was still at risk for going back to stinkies and I did. Vaping keeps me from doing that, so I will vape until I KNOW I'm out of the danger zone of returning to analogs.
