Research Roundup

The UK Electronic Cigarette Research Forum (UKECRF) has presented comment on some recent vape-related studies. In addition, we include links to the sizeable number of other work published during April and May.

Associations between dual use of e-cigarettes and smoking cessation: A prospective study of smokers in England” by Sarah Jackson, Lion Shahab, Robert West, and Jamie Brown

The team found there was no significant difference in the prevalence of quit attempts at follow-up between baseline dual users and exclusive smokers. Dual users of e-cigarettes were less likely than dual users of NRT to have made a quit attempt.

There was no significant difference in success of quit attempts or overall quits in dual users of e-cigarettes compared with exclusive smokers or dual users of NRT. The overall quit rate was nearly 3 times greater in past year smokers who used e-cigarettes compared with those who remained exclusive smokers.

Commenting on the study, the UK Electronic Cigarette Research Forum said: “There was a high rate of drop out between baseline and follow up meaning that the resulting sample size was relatively small, with 292 and 117 participants remaining in the dual e-cigarette and NRT subgroups, respectively. This may result in reduced power to detect an effect on quit attempts, and the results may be subject to bias.

Association between changes in harm perceptions and e-cigarette use among current tobacco smokers in a time series analysis” by Olga Perski, Emma Beard and Jamie Brown

The team found a 1% decrease in the prevalence of smokers who believed that e-cigarettes are less harmful than cigarettes was associated with a 0.48% decrease in prevalence of e-cigarette use among smokers. They believe the changes in the prevalence of smokers who believed that e-cigarettes are less harmful than cigarettes was associated with a decrease in the prevalence of e-cigarette use among smokers.

They noted there was no significant association between this belief and the use of e-cigarettes in 16-24-year olds.

The UK Electronic Cigarette Research Forum stated: “The study looked at an association between trends rather than a causal link. Associations could have been confounded by other factors such as cuts to Stop Smoking Services which were not considered in the analysis.”

European adult smokes’ perceptions of the harmfulness of e-cigarettes relative to combustible cigarettes: cohort findings from the 2016 and 2018 EUREST-PLUS ITC Europe Surveys” by Gravely , Driezen, Kyriakos et al.

Looking at the effects the Tobacco Products Directive (TPD) on harm perceptions of e-cigarettes in six European Union member states, the team found that 28.4% of respondents viewed e-cigarettes as less harmful than cigarettes, 61.8% believed that they were equally or more harmful than cigarettes and 9.8% responded that they did not know whether they were more, less or equally as harmful as cigarettes.

Respondents from Spain and Romania were less likely to believe that e-cigarettes are less harmful than cigarettes. Respondents from Germany were less likely than respondents from Hungary to believe that e-cigarettes were equally or more harmful than cigarettes.

Current e-cigarette users and those who had reported having tried but not currently using e-cigarettes were more likely to believe that e-cigarettes are less harmful than cigarettes compared to those who had never tried an e-cigarette.

The UK Electronic Cigarette Research Forum said: “There were very few e-cigarette users in the sample which may have affected the estimates of harm perceptions among e-cigarette users. The data in the study were self-reported. Therefore, it may have been subject to bias.”
