Description
For sample adults 18 and older who have not smoked 100 cigarettes in their lifetime but have smoked a cigarette at least once in their lifetime (SMOKEPUFFEV) and are currently not smoking at all (SMOKFREQX), SMOKELNO reports the time unit associated with the length of time period for when the respondent last smoked a cigarette. SMOKELTP should be paired with SMOKELNO, which reports the number associated with the time unit for the length of time since the respondent last smoked a cigarette.
