ESRC Postdoctoral Fellowship 2020 - Electronic cigarettes: role in smoking cessation and potential risks for children and young people

My PhD investigated why e-cigarettes have proved to hold such a broad appeal across society, and whether this could be at the cost of smokers using more effective ways to try to quit tobacco. E-cigarettes are now by far the most common choice of quit route for smokers who do not wish to simplygo 'cold turkey' when trying to end their addiction to conventional tobacco cigarettes. However, in contrast to the huge rise in e-cigarettes' popularity, attendances at local stop smoking services (SSSs, which offer one-to-one support from trained smoking cessation advisors) have declined for sevenconsecutive years. Given these services have repeatedly been shown to be considerably more effective than any other routes for quitting smoking, my PhD sought to better understand whether the rise of e-cigarettes could be influencing this drop in service attendance, as well as investigating what kinds of issues influenced smokers when they were weighing up which quit route to use.I have already published two papers of PhD findings. My systematic review filled an important research gap by collating the worldwide scientific literature on which demographic groups were most likely to use e-cigarettes. Meanwhile, a qualitative paper with the results of my 46 interviews delineated the complex range of factors that play a role in smokers' decision-making about whether to use quit routes such as e-cigarettes or SSSs. It also highlighted the diverse attitudes towards e-cigarettes shown by different SSSs and how this influenced the kinds of support offered to their clients.This fellowship would allow me the opportunity to publish two further papers of findings, helping to maximise the potential of my PhD research. The first would be a further quantitative paper showing what kinds of knowledge and beliefs amongst the 2000 smokers that I surveyed were related to their use ofSSSs and e-cigarettes. This would therefore provide a natural complement to my already-published interview findings, giving my research more reach to those audiences who are most comfortable with quantitative analyses. The second would be a further piece of analysis from my qualitative dataset. Inlight of my finding that SSSs offer very varying levels of support and advice around e-cigarettes, my second paper would drill down further into my interview data to tease out what the key influences are that determine what policy a service arrives at regarding e-cigarettes. This would thus provide important insights for PHE, ASH, NCSCT and other organisations with an interest in ensuring equal provision of support to smokers in different parts of the country.Finally, the fellowship would also allow me to develop a funding proposal to move my investigations on to crucial, related research questions in the years following. Specifically, this future bid would involve analysing the impact of 'Juul' e-cigarette devices on vaping and smoking habits amongst children andyoung people, an age group whose attitudes and behaviours fundamentally determine the health harms caused by smoking within society. Most smokers, after all, take up the habit in adolescence, when they have less understanding about the tenacity of nicotine addiction; in previous research, 90% of smokers had started by age 18 and 95% by age 21. The manufacturer Juul have dominated the vaping market for years in the US but have only arrived on UK shores much more recently. These specific devices have been shown to be driving the far higher rates of teenage vaping seen in the US but, as yet, their impact on UK youngsters' vaping and smoking habits are unknown. This line of enquiry has been sparked both by my PhD's systematic review, which showed the highest rates of vaping were amongst older adolescents and younger adults, and by my qualitative fieldwork, where younger interviewees often relayed experiences of feeling targeted by e-cigarette marketing or spoke of the popularity of vaping amongst their peer groups.
