“E-cigarette use does not appear to be associated with current, continued smoking. “Instead, the apparent relationship between e-cigarette use and current conventional smoking is fully explained by shared risk factors, thus failing to support claims that e-cigarettes have a causal effect on concurrent conventional smoking among youth.” As tighter regulations are being enforced upon the vaping industry, such as the flavour ban, this type of evidence should be considered. The initiative behind multiple states enacting an e-liquid flavour ban was due to the belief that vaping is inciting more teenagers to become addicted to nicotine. However, this large-scale study proves otherwise. Selya, an assistant scientist at Sanford Health in South Dakota, said: “It’s really important to hold off making policies on e-cigarettes until we have a more solid understanding of its effects.” Dr Nicholas Chadi, a specialist in addiction medicine and assistant professor of paediatrics at the University of Montreal, underlined the importance of the research. He said: “Several published studies show a signifi cant association between e-cigarette use and current and future smoking [and so] these fi ndings would need to be replicated.” He argued that lifestyle factors could be the explanation behind papers from 2015 and 2016 that contradict this new evidence. Dr Chadi explained products with high levels of nicotine such as JUUL were new to the market and were “just starting to become popular on a large scale at that time.” He added: “So, it’s possible that the same study conducted today would show different results” as e-cigarettes are no longer a new product and are not rapidly increasing in usage rates amongst teenagers anymore. Moving forward, monitoring these same study participants over a lengthier period of time has the potential to strengthen this evidence. This year, Action on Smoking and Health released fi gures “This research undermines the hypothesis that e-cigarettes are a gateway drug to smoking conventional cigarettes.” that showed over 83 percent of 11-18-year olds in Britain had never tried an e-cigarette. They also discovered that not a single ‘never smoker’ teen reported using an e-cigarette on a daily basis, and that almost 50 percent of teenagers tried smoking a cigarette before trying a vaping device. This challenges the conception that there is a teen vaping epidemic in the UK. There are also fi ndings published in the leading medical journal Thorax that demonstrates e-cigarettes are not a gateway drug to tobacco usage. One such study into teenage vaping concluded: “Our research does not support the hypothesis that e-cigarettes ‘renormalised’ youth smoking during a period of growing, but largely unregulated use in the UK.” VM26 27
