Introduction
In 2016, the Finnish Tobacco Act was revised to harmonise e‐cigarette regulations with the EU Tobacco Products Directive. Unlike before, the sale of nicotine‐containing e‐liquids was allowed while additional national regulations included, for example, a ban for other than unflavoured and tobacco‐flavoured e‐liquids. This study examines the correlates of e‐cigarette use before and after the comprehensive regulatory change, and characteristics and correlates of flavoured e‐cigarette use after the flavour ban in the general Finnish population.
Methods
Repeated cross‐sectional population‐based drug surveys for 15–69‐year‐olds in 2014 (n = 3485; 50% response rate) and in 2018 (n = 3229; 46%). Correlates of e‐cigarette use were studied with logistic regression models.
Results
Current e‐cigarette use remained infrequent (approximately 2%) and the correlates of e‐cigarette use varied only slightly between the study years. In 2018, of past‐year e‐cigarette users (n = 316), 43% used unflavoured e‐liquids, 24% used tobacco and 43% used other flavours, fruits being the most common. In univariate models, demographic variables, smoking and e‐cigarette use‐related factors were associated with flavoured e‐cigarette use. In multivariable models, those who used e‐cigarettes to experiment used unflavoured e‐cigarettes more likely than other than tobacco flavours (odds ratio 3.00, 95% confidence interval 1.15–7.82).
Discussion and Conclusions
In Finland, the regulated entry of nicotine‐containing e‐liquids to retail sales has not led to increased e‐cigarette use in the general population. After the flavour ban, other than tobacco‐flavoured e‐cigarette use still occurs. The use of flavoured e‐cigarettes is associated with reasons for e‐cigarette use. Flavoured e‐cigarette use and its correlates warrant further monitoring.
