Recently I've been thinking about what it means to have quit. These thoughts were sparked by recurring debates that come up from time to time on the forum, particularly with regard to prolonged use of NRT, and to a lesser degree with regard to someone who no longer "really" smokes, but who has an occasional puff at a social event. What about the person who quit smoking six years ago but who still uses a nicotine filled e-cig, or a nicotine inhalator? What about that person who is using nicotine gum on a daily basis two years after their quit? What about the person who's smoking herbal cigarettes, containing no nicotine?
Where do we draw the line on what constitutes having quit?
