I don't think most doctors are going to want you to vape but if it helps you quit smoking most would probably prefer you vape. My Dr prefers me to do neither as most probably do. I did directly ask him about vaping and he strongly advised using a different method and to get away from the nicotine. He believes that while smoking and vaping are different in mechanism he feels both equate to a smoking type activity and often it leads right back to smoking or dual use. He suggests the goal should be to eliminate nicotine not substitute one behavior of addiction for another. He knows I do both and have no plans on quitting but that was his advice when directly asked.
Unfortunately, many doctors have not yet realized the the "perfect" is enemy of the "good".
In their mindset, the "perfect" solution, of course, would be we quitting with pharma products, that do NOT mimic the act of smoking, albeit with nicotine in them. After some weeks of treatment, you would quit those products too, getting you rid of both smoking and the "evil" nicotine.
Trouble is, "perfect" solutions, or even "great" solutions, are only perfect or great as long as they ACTUALLY work.
Because NRT's do not work for +90% of people, it means that for those people, "perfect" or "great" solutions become USELESS.
By definition, a useless solution is a BAD one, because it does not adress the problem it was meant to solve.
If I had to choose between a "good" solution or a bad, useless one, I would go for "good" any day. Even if "good" is NOT "perfect".
This reminds me of an interview with a Portuguese doctor, president (or ex-president?) of our local "lung association".
She was bashing e-cigaettes, of course, exactly with the argument that "it mimics smoking", so people are just "trading an addiction for another". (In fact, we MAY be trading an addiction for a DEPENDENCY, but that's for another post).
What scared me most, is that she even talked about some Pharma product, released some years ago, that was similar to our 1st generation devices.
Whas it working at keeping people away from smoking? YES. It had a much higher success rate than other traditional NRT's (that was to be expected, because it addressed the behavioral side of cigarette addiction).
But, alas, our "wise" doctors realised people were starting to use that device long-term (they did not have a problem about people using the patch or gum for years, which can be bought over-the-counter). But somehow, using that Pharma cig-alike device was a no-no, even if it was clearly more effective at what REALLY mattered - keeping people away from cigarettes.
So, having put ideology above science and the patient's real interests, they decided it was time to remove that product from the market.
Why should our doctor's concern about OUR nicotine and behavioral DEPENDENCY override OUR concen about our former tobacco cigarettes ADDICTION, with the attached health problems that WE could have suffered in the future?
