Note. All data were weighted to account for the complex survey design. CI = confidence interval.
aA 6-point scale calculated from the number of cigarettes smoked per day (1–10, 11–20, 21–30, and >30 cigarettes) and the time to first cigarette after waking (≤5, 6–30, 31–60, and >60min). Scores of 0–1 are categorized as “low nicotine dependence,” 2–4 as “moderate,” and 5–6 as “high.”
bCalculated by multiplying the average number of cigarettes smoked per day by the self-reported number of days in which the respondent smoked cigarettes in the past 30 days.
cIncluding cigars, pipes, snuff, or chewing tobacco.
