The Australia Smoking and Vaping Model: The Potential Impact of Increasing Access to Nicotine Vaping Products.

Australia has implemented a strong array of cigarette-oriented policies, but has restricted access to nicotine vaping products (NVPs). The Smoking and Vaping Model offers a framework for modeling hypothetical policy scenarios. The Australian model shows the potential for public health gains by maintaining cigarette-oriented policies while relaxing the current restrictive NVP policy. Modeling results under a permissive NVP policy are particularly sensitive to the estimated rates of smoking cessation and switching to vaping, which are not well established and will likely depend on past and future cigarette-oriented policies and the specific NVP policies implemented in Australia.
