Developing a novel e-cigarette regulatory and policy control scale: results from the European Union

E-cigarette regulations vary considerably between countries though a standard approach for comparing regulatory frameworks does not exist. Additionally, there is no evidence on whether regulatory variations are associated with differences in e-cigarette use and smoking cessation. This study aims to develop a regulatory scale to measure and compare e-cigarette regulations between European Union countries and investigate whether scores are associated with e-cigarette use and smoking cessation.

Data from a range of sources, such as ECigIntelligence, were used to develop a scale and score countries in the respective areas of e-cigarette scale. We used correlation analysis to investigate association between scale scores and e-cigarettes market, e-cigarette prevalence and use of e-cigarettes for smoking cessation.

An e-cigarette scale consisting of 10 domains was developed. Our analysis suggests that higher e-cigarette scale scores were associated with significantly greater use of e-cigarettes within countries, and greater increases in the prevalence of former smoking smokers between 2014 and 2017.

Whilst further work is needed to develop the scale in line with rapidly changing regulatory landscape and product development, the current findings suggest that countries that have implemented e-cigarette regulations might be more successful in obtaining public health gains such as increase in the proportion of former smokers compared to countries where e-cigarette market and sales is not regulated.
