Could vaping help lower smoking rates in Australia?

In this brief article, we review the evidence on whether easier access to vaping could help lower smoking rates in Australia. To make a convincing case for vaping the following conditions need to be met: that vaping assists in smoking cessation; that the prevalence of vaping is high enough to produce measurable effects at a population level; and that the decline in smoking prevalence is slower in countries where vaping is less common. The evidence suggests that these criteria are satisfied.
