N= number of participants; wt %= weighted percentage; cpd=cigarettes per day smoked on the days in which the participant smoked during the previous month

^*Cells were suppressed due to cell sizes.

¹Participants were asked if any of their three best friends smoked.

²Cut point was a score of 24 on the Center for Epidemiologic Studies Depression Scale.
