†Of n=8679 cigarette smokers, n=6658 said the last cigarette they smoked was a brand of FM cigarettes. We excluded those who did not provide their brand name of the last cigarette they smoked (n=193), or who reported a brand of e-cigarettes, cigars or cigarillos (n=11), or who purchased their current pack duty-free or from overseas (n=60). Analysed n=6395.
‡Models did not control for respondent characteristics due to low cell sizes.
§In addition, those who did not provide a valid pack size (n=126) were not asked where they purchased their cigarettes from and were excluded from the ‘informal seller’ analyses; analysed n=6268.
FM, factory-made; PP, plain packaging.
