480 never or experimental smokers at baseline used in analysis.

Never‐smoker/ non‐susceptible (Never puffed on a cigarette and 'Definitely not' response to 'Do you think you will smoke a cigarette in next 6 months?' and 'Would you smoke a cigarette if best friend offered you one?'
Never‐smoker/ susceptible (Never puffed on a cigarette and answered affirmatively to smoke if best friend offered, and smoking a cigarette during the next t6 months)
Puffer (not more than 1 cigarette)
Experimenter/Not current (2‐100 in lifetime but none in past 30 days)
Experimenter/Current (2‐100 in lifetime and smoked in past 30 days)
Regular (> 100 in lifetime)
('bogus pipeline' used to increase self‐report validity) |
