Exposure to and perceptions of health warning labels on nicotine vaping products: findings from the 2016 International Tobacco Control Four Country Smoking and Vaping Survey.

Findings—Compared with respondents in EN, respondents in CA were more likely to report having noticed HWLs (OR=1.58, p=0.02) whereas respondents in AU (OR=0.76, p=1.00) and the US (OR=1.54, p=0.09) were not significantly more or less likely to report having noticed HWLs. Compared with concurrent smokers and vapers, daily smokers, non-daily smokers, and quitters were less likely to report having noticed HWLs, (ORs=0.21, 0.33 and 0.19 respectively, all p<0.001). There were no significant differences in reports of noticing HWLs when comparing concurrent smokers and vapers with daily (OR=1.62, p=0.91) or non-daily (OR=1.15, p=1.00) vapers. There were no significant differences by country in reporting that HWLs made them concerned about using NVPs. Daily vapers were less likely to report feeling concerned than concurrent users (OR=0.11, p=0.017). Among those who reported reading HWLs (n=688), there was little evidence of differences in recall of the HWL content.
Conclusions—Respondents in England, where health warning labels on nicotine vaping products are mandatory, were not significantly more likely to report having noticed such warnings than those in Australia, Canada and the US where warnings are not mandatory.
