Current smokers were defined as anyone who reported smoking cigarettes (including hand-rolled), or tobacco of some kind (eg. cigar or shisha) at the time of the survey. Past-year smokers were defined as anyone who was a current smoker (as defined above) or who had stopped smoking completely in the last year. Among past-year and current smokers, the following smoking and smoking cessation attempt characteristics were measured: time to first cigarette (as an indicator of cigarette dependence; more than 60 minutes/30-60 minutes/6-30 minutes/within 5 minutes [ref]23); cigarettes smoked per day (continuous); use of roll-your-own tobacco (yes/no [ref]), and any serious quit attempts in the past 12-months (yes/no [ref]). A serious quit attempt was defined to respondents as an attempt to “try to make sure you never smoked again” and to include any current attempt and any successful attempt made within the last year. Of those who had made a serious quit attempt, respondents were also asked: time since start of the most recent quit attempt (last week [ref]/between a week and a month/1-2 months/2-3 months/3-6 months/6-12 months); abrupt versus gradual [ref]
