I concur that smoking thoughts and desires get farther and farther apart as we practice not smoking, but I think some people continue to have smoking thoughts and desires, from time to time, throughout their lifetimes. I had a smoking thought and a craving after I had finished eating at a cafe in San Francisco over the Christmas holiday. It was so subtle an unexpected that, at first, I didn't recognize it. That told me that I still have to be careful. I cannot manage what I don't recognize and name.
