From the 2008 National Health Interview Survey:
Have you smoked at least 100 cigarettes in your entire life?
Do you now smoke cigarettes everyday, some days, or not at all?
Persons are considered as using cigarettes if they report that they smoked at least 100 cigarettes in their lifetime and now report smoking cigarettes everyday or some days.
Starting in 1992, NHIS has defined current smokers as persons who have smoked at least 100 cigarettes and now smoke either everyday or some days. The 1992 inclusion of intermittent smoking increased the prevalence of smoking by approximately one percent compared with estimates derived from the previous smoking definition.
