Granny is not gonna quit smoking.
I hope that you are wrong. It's tough, but it can be done. I quit drinking 25 years ago, and that was no fun, but it was nothing like quitting nicotine. If I ever get a terminal diagnosis, I will go back to chewing tobacco in a heartbeat (pun intended) but I will never drink again. Tobacco is a proven big time killer. Marijuana is banned, but tobacco is okay. It's all about the $.
