Smoking Profiles.

Note: Each cell reports sample size for that group. For lifetime smoking history, “none” indicates having never smoked, “moderate” indicates having smoked but fewer than 100 cigarettes, and “heavy” indicates having smoked 100 or more in a lifetime. For recent smoking history, “inactive” indicates having not smoked in the previous 30 days, “occasional” indicates having smoked in some but not all of the previous 30 days, and “daily” indicates having smoked all of the previous 30 days.
