Figure 1. Mandated Health Warning Labels (HWLs) with Qualitative Information about Toxic Constituents and Smoking-related Risks on Cigarette Packages for Australia, Canada, Mexico, and the US in the Survey Waves*.

Figure 1.

*Mexico changed the HWL content every six months but HWLs stay on the market for a substantial period afterwards, given that the law does not specify when HWLs are no longer allowed to be sold. Hence, information printed on packs in the period before the study began was likely to be on HWLs over the entire study period, although their presence is likely to have diminished over time.
