The study says that flavoured vapes are much less harmful to young people than smoking and could help teen smokers quit tobacco. It finds that flavours are an important aspect of vaping that young people enjoy, suggesting that flavoured products may help them switch away from harmful tobacco smoking.
Lead researcher, Professor Caitlin Notley, from UEA’s Norwich Medical School, said: “There has been a lot of concern that young people may start vaping because they are attracted to e-liquid flavours, and that it could potentially lead them to start smoking tobacco.
“We wanted to find out more about the links between vape flavours, the uptake of vaping among young people, and whether it leads to regular vaping and, potentially, tobacco smoking.”
The research team studied all available evidence (58 studies) on young peoples’ use of e-liquid flavours.
Prof Notley continued: “We found that flavoured e-liquids are an important aspect of vaping that young people enjoy. This suggests that flavoured products may encourage young people to switch away from harmful tobacco smoking towards less harmful vaping.
“Flavours may be an important motivator for e-cigarette uptake – but we found no evidence that using flavoured e-liquids attracted young people to go on to take up tobacco smoking.
“And we also found no adverse effects or harm caused by using liquid vape flavours.
“However, there is also a need to monitor flavour use to ensure that young people who have never smoked are not attracted to taking up vaping.
“Ensuring the continued availability of a range of e-liquid flavours is likely to be important in encouraging young people who smoke to switch to vaping as a less harmful alternative,” she added.
The team found that the overall quality of the evidence on use of e-cigarette flavours by young people was low. In particular, many studies did not clearly define e-liquid flavours and could not therefore be included within the review.
The study was led by UEA in collaboration with researchers at University College London, the University of Bristol and University Hospitals Bristol and Weston NHS Foundation Trust.
