Hello Betsy:
I wish I had some great inspirational answer for you on how you can get a person who does not want to quit smoking to go for help or even be able to accept help if dragged into it. The truth of the matter is though, you cannot make another person quit smoking. You can possibly make smoking difficult to impossible for some people if they are too infirmed to get cigarettes without outside assistance--but even this solution is likely to be a temporary solution for once the person is out on his or her own again and has the resources, he or she will often go back to smoking.
I don't want to make this sound hopeless though. While it is very difficult to get a person to quit who does not want to, there is also the possibility that at some level she does want to quit, but fear of quitting is keeping her from admitting that fact to you or anyone else--including her self. If you can get her to realize that quitting is possible and will result in a better quality of life--you may find out that you are not in the position of trying to get her to do something that she doesn't want to do, but more in the role of an advocate for her to help her to quit smoking because she now want to do it.
I am going to attempt to attach a series of links below that address what a person can do and can't do to help another to quit. Hope these articles help.
