Abstract

Aims

In Australia, sales of nicotine containing electronic cigarettes (also known as e-cigarette) are banned unless approved as a therapeutic good. The aims of this study were to estimate the prevalence of e-cigarette use and its correlates in Australia using a nationally representative survey.

Method

We analysed data from the largest drug use survey in Australia (the National Drug Strategy Household Survey [NDSHS]; N = 22,354) .

Results

We estimated that 227,000 Australians (1.2% of the population) were current e-cigarettes users, and 97,000 (0.5%) used them daily. Individuals who were male, younger, had higher level of psychological distress, and smoked were more likely to use electronic cigarettes. Among smokers, an intention to quit and reduction in smoking was associated with experimentation and daily use of e-cigarette, but not with occasional use. Recent quitting was associated with daily use.

Conclusion

Overall, the prevalence of e-cigarette use was low in 2016 in Australia. Smoking status was the strongest correlates of e-cigarette use. Patterns of vaping were differentialy associated with an intention to quit smoking, smoking reduction and recent quitting. Some smokers may attempt to use e-cigarettes to cut-down their tobacco use, and those who vaped daily were mostly likely to be recent quitters.
