Smokers who showed the pack of their last purchase and all smokers. Rio de Janeiro and São Paulo cities, 2019.
*We used the official list of legal brands authorised by the Brazilian Health Regulatory Agency and the direct observation of the presence of Brazilian health warnings to define the legal status.
†P>0.300 in Pearsonχ2 tests for comparison of two proportions with sampling weight across methods for Rio de Janeiro or São Paulo.
‡Individuals who reported having bought at least one cigarette pack in their last purchase and who informed having paid less than the minimum price established by law, that is, <5.0 Brazilian Reais per pack.
§We excluded smokers who did not provide information on self-reported price per pack (0.2% in Sao Paulo and 0.0% in Rio de Janeiro).
¶Legal brands authorised by the ANVISA with the presence of Brazilian health warnings, but sold below 4.7 Brazilian Reais were also coded as illegal.
**For smokers who did not show the pack of their last purchase, illegal consumption was based on (1) individuals who informed having paid less than 4.7 Brazilian Reais for a cigarette brand authorised by the ANVISA or (2) who informed having bought an illicit cigarette brand.
