背景：电子烟（EC）在全球越来越受欢迎。如果它们要取代传统香烟，可能会对公众健康产生重大影响。为了评估电子烟作为消费品与传统卷烟竞争的潜力，我们报告了据我们所知，关于尝试电子烟并成为经常使用者的吸烟者比例的第一批数据。方法：我们采访了捷克共和国总共 2,012 名吸烟或购买卷烟的人，以回答有关吸烟的问题，但没有提及电子烟，以避免电子烟用户调查中的常见偏见。在采访过程中，我们讨论了志愿者使用电子烟的经历。结果：共有 1,738 名吸烟者（86%）参与。一半的人表示至少尝试过一次 EC。在尝试 EC 的人中，18.3%（95% CI，0.15.7%-20.9%）表示经常使用它们，14%（95% CI，11.6%-16.2%）每天使用它们。普通用户平均每天使用 EC 的时间为 7.1 个月。使用电子烟的最常见原因是减少传统卷烟的消费； 60% 的 EC 常规用户表示 EC 帮助他们实现了这一目标。年龄较大且对 EC 的初始体验更有利，解释了 19% 的进展为定期使用 EC 的差异。结论：尝试过 EC 的吸烟者中，近五分之一会继续成为常规使用者。电子烟可能会发展成为传统卷烟的真正竞争对手。准备监管电子烟的政府机构需要确保此类举措不会造成传统卷烟的市场垄断。
Background: Electronic cigarettes (ECs) 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, to our knowledge, on the proportion of smokers who try ECs 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 ECs to avoid the common bias in surveys of EC users. During the interview, the volunteers' experience with ECs was then discussed.Results: A total of 1,738 smokers (86%) participated. One-half reported trying ECs at least once. Among those who tried ECs, 18.3% (95% CI, 0.15.7%-20.9%) reported using them regularly, and 14% (95% CI, 11.6%-16.2%) used them daily. On average, regular users used ECs daily for 7.1 months. The most common reason for using ECs was to reduce consumption of conventional cigarettes; 60% of regular EC users reported that ECs helped them to achieve this. Being older and having a more favorable initial experience with ECs explained 19% of the variance in progressing to regular EC use.Conclusions: Almost one-fifth of smokers who try ECs once go on to become regular users. ECs may develop into a genuine competitor to conventional cigarettes. Government agencies preparing to regulate ECs need to ensure that such moves do not create a market monopoly for conventional cigarettes.
