Some people view their cigarettes as a "friend" which has been their constant companion for most of their life and in most difficult time of their life. When they stop smoking they may feel deprived of this friendship, and feel that "something is missing". Often people need to fill the gap that smoking leaves with something positive like a new hobby or pastime. With time they may come to realisation that the cigarette was an expensive "friendship" to maintain and never did you any favours.
