Note. P30D: Past 30 days. Bold: p <.05. Participants are N = 11,153 adults who currently smoked at baseline, had an established smoking history at baseline, and completed the 12 M follow-up as well as 1 + follow-up in Y2
a: In addition to adjusting for baseline smoking behavior and history, sociodemographic characteristics were also adjusted for in these models
b: Baseline cigarette consumption is an average of cigarettes per day (CPD) over P30D, including nonsmoking days (i.e. CPD on smoking days × number of days smoked in P30D / 30 days)
c: Number of smoking days in P30D
d: Years of smoking duration at baseline
e: Assessed using the Adult Tobacco Dependence (TD) Index, a composite of 16 items ranging from 1 (low dependence) to 5 (high dependence)
