I smoked from about 15 to 18 and then started again at 22. I am going to be 27 in April, and will also be celebrating 1 year with no cigarettes. I do smoke cigars and pipe tobacco from time to time, but it's not even really a routine because it's pretty random and both of those things take time to do. Cigarettes were so easy to smoke on my way to/from places, or before/after events that it drove me nuts. I quit cold turkey and think that it really is about trying to concentrate on the things you did while smoking and trying to do them without smoking.
