Measures
Current smoking and social smoking status
Participantswho smoked at least one day of the past 30 dayswere classified
as current smokers. Current smokers also reported the average number of cigarettes
smoked on a smoking day (CPD). All participants who answered “yes” to
“are you a social smoker?” were classified as “self-identified social smokers.” In
a separate question, participants reported if they only smoked alone, mainly
smoked alone, smoked as often alone as with others, mainly smoked when
others are smoking, or only smoked when others are smoking. Those who
smoked mainly or only when others are smoking were defined as “behavioral
social smokers.”
