It's not always the nicotine.
In fact, more often than not it may not be the nicotine at all.
Not everyone that has quit smoking has done so because of the same exact magic bullet.
Nor are people that keep smoking doing it for the exact same reasons.
This is wonderful, DC. Although I smoked for 39 yrs, almost 4 decades, I'm actually very slightly addicted to nicotine, for several reasons. I switched from Lights to Ultra-Lights more than 20 yrs ago, and even with ultra-lights, I had to learn a method of inhaling that actually turns out to be rather similar to the suggested method for vaping: inhaling slowly, and shallowly. I had to switch, and change my inhalation method, because of my asthma; I could no longer tolerate even a Light, and I could not tolerate the traditional smoker's deep inhale. Yes, I definitely should have probably just quit smoking entirely at the time I switched and changed my inhalation, because of my asthma, but I did try, and fail, twice -- so I had to find a way to accommodate my asthma with my continuing smoking habit.
Many people find that when they go from full to lights, or lights to ultra-lights, they begin to smoke more, and that probably happened with me as well -- but 16 or 17 yrs ago, I was forced to stop smoking indoors, by my son's health problems; taking my smoking outdoors meant my habit went immediately from 3+ pks a day, to 2 pks a day. And as the prices of cigarettes continued to rise, I continued to cut down, until I was smoking just one pk a day.
When I first got here in January and learned what I needed to know to find a decent cigalike (an eRoll), I had ZERO intention of quitting; what I sought was a way to "smoke" indoors without stinking up the place, because it's damn cold in January, and last winter was our coldest winter in over 30 yrs. But when I got here and started reading of all those who "accidentally" quit because e-cigs were just that good, I began thinking of all the reasons why I really did need to quit, and recalling that I had wanted to be a non-smoker for quite a while, but could not find a way to get there, without such suffering that I gave up the effort -- I wanted to be a non-smoker without having to suffer to get there.
So, when I got my eRoll, I began using it as I had originally intended -- mainly at night, when it was cold, but even that was somewhat hampered by not being able, at first, to find an ejuice that really "did it" for me. That took a few weeks. When I finally got an ejuice that many had said tasted a great deal like VA Slims, I wasn't really expecting much, I had been so disappointed by the other tobacco flavors I had tried -- but my very first puff was so astonishing, I remember FEELING my eyes get wide, because in a great many ways, it really did taste like the cigarettes I had smoked for more than 30 yrs. At that point, I began a campaign to just SEE how many cigarettes I could replace with vaping. That was about the end of the first week of Feb. By the last week in Feb, my "tally" was down to less than 5 cigarettes a day; the last 3 days I smoked, I smoked just one cigarette that day, the right-after-waking smoke, and I realized -- if I could get by with just 1 cigarette a day, I could most likely get by just fine without it, and on Feb 28, I did exactly that. Nobody was more surprised than I.
So, I was not a heavy smoker, nor did I smoke very strong cigarettes, nor was I really interested in quitting -- but I was a very long-term smoker who had tried many times to quit, without success -- yet I succeeded in quitting smoking without trying terribly hard to do so. Yes, there was some effort involved, but mainly of the "let's see if this really works" variety. It did.
This summer, after my appendectomy, I returned to smoking -- but by using pretty much the same technique, increasing vaping while decreasing smoking, I was able to do it a 2nd time, in just about the same amount of time, about a month. There was more effort required, because it was no longer a novelty, but I put the cigarettes down completely while still smoking 5 per day, simply because I KNEW it was possible. When cravings came back around my 10th day smoke-free, rather than go back to smoking AGAIN, I began adding WTA -- and I echo whoever said it above, that WTA took the place of strenuous willpower, because the cravings departed and have not returned.
