Acceptance and patterns of personal vaporizer use in Australia and the United Kingdom: Results from the International Tobacco Control survey.

BACKGROUND

This study examined the prevalence and correlates of (1) perceived social acceptability of personal vaporizer (PV)/e-cigarette use, and (2) reported vaping in public and private places, in the UK and Australia with different regulatory environments for PVs.

METHODS

Data analyzed come from 2849 smokers and recent ex-smokers in the UK and Australia who participated in the 2014 wave of the International Tobacco Control Survey.

RESULTS

UK respondents were more likely to think vaping is socially acceptable than Australians (56.4% vs. 27.9%; p < 0.001). Having quit smoking, observing vaping in smoke-free (SF) public places, and believing vaping is less harmful than smoking was all significantly associated with greater perceived social acceptability of vaping in both countries. However, vaping status and that of friends and family were more influential in Australia than in the UK. Vaping was reported as much more common in private, than public, settings in both countries. UK vapers were more likely to report vaping in SF public places (OR = 2.66; 95% CI = 1.5-4.7; p < 0.01) and at home (OR = 2.44; 95% CI = 1.5-3.9; p < 0.001), but not in their car when controlling for demographic factors and vaping and smoking status.

CONCLUSION

The acceptability of vaping was greater among those who were more exposed to vaping and not just among those with some personal experience of vaping, suggesting no strong social barriers to increased use. Vaping in SF public places was less common than in homes, and both were more common in the UK than in Australia, suggesting some social constraints on use, particularly in Australia.
