Evaluating Nicotine Levels Selection and Patterns of Electronic Cigarette Use in a Group of Vapers Who Had Achieved Complete Substitution of Smoking

摘要

BackgroundElectronic cigarettes (ECs) are alternative-to-smoking nicotine delivery devices; consumers (commonly called vapers) use them in order to reduce or completely substitute smoking. The European Commission has released a proposal for a new Tobacco Product Directive that might reduce availability of nicotine-containing products, including ECs. In this study, the EC use patterns in subjects who have completely substituted smoking with EC use were examined by personal interviews. The study focused on nicotine levels used in order to achieve smoking cessation, reported benefits, associated side effects, and estimation of EC dependence compared with smoking.
