• †Discontent index: the responses from items smoker regret, perceived addiction and intention to quit was used to create a classification grid to assign a score from 1=low discontent to 5=high discontent (see online supplementary figure S1). Levels #1 and #2 are combined as Low, Level #3 is Moderate, and Levels #4 and #5 are combined as High for the multinomial logistic analyses.
