There are a few people though whom you may encounter over your lifetime that did quit using NRT's as intended, weaning down for week after week and eventually quitting. If the person is now off for years, he or she is pretty much in the same state as a person who had quit cold turkey. He or she is nicotine free, and he or she should be thrilled by that fact. In some ways I look at people like this with a bit of awe, for they in all likelihood stuck with a process that was pretty much a gradual and prolonged withdrawal and yet they succeeded. Again, debating the merits of their method with them is pretty much a moot point. It worked for them and you are going to have a pretty hard time convincing them that it is an ineffective method. But you do have a message that you can share with them that they do need to know. That message is that even though they are off nicotine for years, they still need to recognize that they are not cured of nicotine addiction and never will be. No matter how they had stopped, they must still understand the bottom line message, that the only way to stay free now is staying totally committed to never administer nicotine again via any nicotine replacement source and to never administer nicotine again from the original source that likely started the whole process by knowing to never take another puff!
