You betcha! My very first check-up after I had switched to vaping, I hadn't even seen the doc yet to give him my good news -- the nurse was leaning in close to put the BP thing around my upper arm, and she looks up at me with a surprised expression -- "Did you quit smoking?" she asked in something like shock. Gave her a big ol grin and said I sure did, I tried vaping like I told the doc I would last time I was here, and that stuff really works! I'd been quit at that point almost a year, which was truly miraculous -- best I ever managed before, back in 1984, was 3 months. They still applaud it, everytime I go in, because they can tell immediately, I don't reek.
As my doc has said over and over... "ANYTHING is better than smoking!!!"
