Calling smoking cessation aids a "crutch" is really, I think, quite disrespectful to those using them.
As far as I'm concerned, it really doesn't matter whether they actually "work" or not. Even if it's just the placebo effect, that's fine with me.
I know that there are a lot of smokers who know the risks of smoking, but who never even make the attempt to quit because they're so fearful of failure. If they have something they believe will help them, then at least they're trying and, as far as I'm concerned, that's all that really matters.
Research has conclusively shown that most smokers do not quit for good on their first attempt. But the greater the number of attempts, the greater the likelihood that they will succeed. So I figure anything that gets them to at least make an attempt is all good.
Each of us has to go about this in the manner that works best for us. Whether that's NRT, Chantix, hypnosis, cold-turkey, the EX program (with or without aids...and who, by the way, pays for this site...neither the authors nor the publishers of "The Easy Way to Stop Smoking" contribute a dime) or whatever. No one person has the answer for everybody, and no one method is the only "right" one.
