I'm not as hard line on this as Sazerac, although I understand her stance and respect it.
In my mind there's the nicotine addiction issue and to get past that clearly you have to stop putting nicotine into your body but, weening completely off nicotine can wait for those who feel they can not quit cold turkey (I was a cold turkey quitter, by the way).
The biggest hurdle to me in quitting is your day to day life habitual smoking routine. Whether you smoke cigs or vape, it's the "garb a smoke" reaction to so many daily life events that is the hardest thing to get past and takes the longest period of time to reconstruct your life. I get the fact that some may want to soften the early quit challenges by continuing to feed nicotine via a properly controlled NRT program. It has clearly worked for some, as has prescription medication such as Zyban and whatever else that's called. I do believe that stopping the flow of nicotine ASAP is also a requirement but just not at the very start of one's quit. What concerns me more than the patch programs are these gums, sprays and lozenges. Those items seems like candy to me. Therefore, more difficult for people to control the dosage plus the temptation to combine any number of NRT's without appropriate medical consultation. Too many want to believe there's a magic bullet out there somewhere that will eliminate the hard work aspect of quitting and that's just not the case.
No question, there are potential issues with NRT's but they have done a lot of quitters a service and continue to do so if used appropriately.
