*p<0.05, **p<0.01, ***p<0.001 indicates the test of comparisons of proportions result. The degree of violation of the minimum price law (MPL) was tested against the immediately preceding wave. MPL violation is determined based on inflation-adjusted 2011 prices. Illicit brands are not disaggregated by packaging type due to the low number of illicit brand purchases by single sticks that were observed during the study (n=55).
