Abstract
Background: Electronic cigarettes (EC) are becoming increasingly popular globally. If they were to replace conventional cigarettes, it could have a substantial impact on public health. To evaluate EC’s potential for competing with conventional cigarettes as a consumer product, we report the first data on the proportion of smokers who try EC and become regular users.
Methods: A total of 2,012 people seen smoking or buying cigarettes in the Czech Republic were approached to answer questions about smoking, with no mention made of EC to avoid the common bias in surveys of EC users. During the interview, the volunteers’ experience with EC was then discussed.
Results: 1,738 (86%) smokers participated. Half reported trying EC at least once. Among those who tried EC, 18.3% (CI (95%) .15.7 to 20.9%) reported using them regularly and 14% (CI (95%) 11.6%-16.2%) used them daily. On average, regular users used EC daily for 7.1 months. The most common reason for using EC was to reduce consumption of conventional cigarettes; 60% of regular EC users reported that EC helped them to achieve this. Being older and having a more favourable initial experience with EC explained 19% of the variance in progressing to regular EC use.
Conclusions: Almost one fifth of smokers who try EC once go on to become regular users. EC may develop into a genuine competitor to conventional cigarettes. Government agencies preparing to regulate EC need to ensure that such moves do not create a market monopoly for conventional cigarettes.
