Communities in wave 1 implemented flavoured tobacco restriction policies from October 2015 to March 2016, while communities in wave 2 implemented these policies from April 2016 to September 2016. Communities in the no restriction group do not have this policy (at the time study was conducted).
*P<0.05 for Wilcoxon rank-sum tests comparing wave 2 communities and no restriction communities.
†Flavoured product availability is the availability of at least one of the following three products in tobacco retailers: a flavoured cigar/cigarillo, a flavoured e-cigarette or a flavoured e-liquid. Flavoured products are defined as those with a characterising flavour (eg, candy, fruit and alcohol), excluding menthol/mint flavours.
