“Even if the evidence for a gateway hypothesis were stronger, it would not justify a ban on the sale of nicotine vaping products to adults” The vaping to smoking gateway effect only makes sense if young people are vaping nicotine e-liquid. However, research cited in the evidence review found that many teen vapers used nicotinefree e-liquid or vaped other things such as cannabis which could not fairly be labelled as ‘vaping’ in this context. But the big takeaway from the review is that vaping is far more likely to be a gateway out of smoking than into it. Mendelsohn and Hall cite a 2017 survey, which found that twothirds of 12 to 17-year-olds who had ever vaped tried cigarettes first. Meanwhile, the 2013-2016 US Population Assessment of Tobacco and Health (PATH) study found that 85 percent of current smokers aged 12 to 15 had not vaped before they tried cigarettes. Meanwhile, youth smoking rates have declined since vaping became popular in 2014. The gateway effect has been used to justify bans across the US, particularly with regards to flavours and nicotine content. Co-authors Colin Mendelsohn and Wayne Hall asked a straightforward question: ‘Does the gateway theory justify a ban on nicotine vaping in Australia?’ A 2019 study published in the journal Tobacco Control aggregated smoking data from five different countries. It found that the decline in past 30-day tobacco-use accelerated as much as four-fold in teens and young adults. In England which supports vaping for harm reduction, smoking prevalence among 16 and 17-year-olds fell by 60 percent between 2015 and 2019, according to the cited Smoking Toolkit Study from 2019. Gateway theory suggests that e-cigarette use leads to tobacco use. However, the authors argued that the link could instead be explained by a common liability model. Mendelsohn and Hall concluded: “Even if the evidence for a gateway hypothesis were stronger, it would not justify a ban on the sale of nicotine vaping products to adults. It’s pretty straightforward. Think back to your school days and the kids your parents warned you about. Big Barry at the bike sheds wasn’t just smoking cigarettes. He was drinking down the park with his mates at weekends and engaging in some light vandalism, too. He was just more of a risk-taker. The researchers wrote: “Regular vaping by never-smokers is rare and the association is more plausibly explained by a common liability model. “If there is a gateway effect, it is small at the population level because smoking prevalence has continued to decline despite an increased uptake of vaping in countries that allow it.” “More proportionate regulatory policies could minimise youth uptake while allowing adult smokers to access these products for cessation or as a lower risk substitute for cigarette smoking.” Regardless of what the experts say, Aussie vaping advocates still face an uphill battle. The country’s historic distrust of the tobacco industry has created scepticism of harm reduction initiatives coming from adjacent industries. The vaping gateway effect has been debunked by numerous European experts. But if the US situation has taught us anything it’s that expertise from within a nation’s own borders carries the most weight when it comes to public policy. VM29 87
