  • ***p≤0.001, **p<0.01, *p<0.05.

  • †Of n=8679 cigarette smokers, those who did not provide their current brand name (n=283) or their current pack size (n=195) were not asked about their place of purchase. We also excluded those who did not know where their current cigarettes/tobacco was purchased (n=61), refused to provide the source or responded not applicable (n=6), mistakenly skipped the question due to coding of previous brand or pack size responses (n=11) or did not have SES information (n=173). Analysed n=7950 (pre-PP n=2079; transition n=707; PP n=5164).

  • ‡Models controlled for sex, age group, SES and education, with the exception of the model predicting ‘Internet purchase’ which did not control for respondent characteristics due to low cell sizes resulting in collinearity issues.

  • PP, plain packaging; SES, socioeconomic status.
