As the popularity of electronic cigarettes (e-cigarettes) increases, it is becoming important to find out more about the characteristics of e-cigarette users, why and how they use the product and whether e-cigarettes are used exclusively or in combination with conventional cigarettes. The objective of this study was to investigate patterns and effects of e-cigarette use and user beliefs about e-cigarette safety and benefits.
E-cigarette users in Poland were recruited online and asked to participate in a web-based survey. The participants provided information on their smoking history, patterns of e-cigarette use, beliefs and attitudes regarding the product and information on concurrent use of conventional cigarettes.
The survey was completed by 179 e-cigarette users. Almost all participants used e-cigarettes daily. E-cigarettes were primarily used to quit smoking or to reduce the harm associated with smoking (both 41%), and were successful in helping the surveyed users to achieve these goals with 66% not smoking conventional cigarettes at all and 25% smoking under five cigarettes a day. Most participants (82%) did not think that e-cigarettes were completely safe, but thought that they were less dangerous than conventional cigarettes. Sixty percent believed that e-cigarettes were addictive, but less so than conventional cigarettes.
The participants primarily used e-cigarettes as a stop-smoking aid or as an alternative to conventional cigarettes, and the majority reported that they successfully stopped smoking. More data on e-cigarette safety and its efficacy in harm-reduction and smoking cessation are needed.
随着电子烟（e-cigarettes）的普及，了解电子烟使用者的特点、他们使用电子烟的原因和方式，以及他们是否仅使用电子烟或与传统香烟一起使用，变得越来越重要。本研究旨在调查电子烟使用的模式和效果，以及用户对电子烟安全性和益处的看法。
在波兰，通过在线招募电子烟使用者，并邀请他们参与一项基于网络的调查。参与者提供了他们的吸烟史、电子烟使用模式、对产品的看法和态度以及与传统香烟同时使用的信息。
共有 179 名电子烟使用者完成了这项调查。几乎所有的参与者都每天使用电子烟。电子烟主要用于戒烟或减少吸烟带来的危害（各占 41%），并成功帮助调查参与者实现了这些目标，其中 66%的人完全不吸传统香烟，25%的人每天吸烟不到 5 支。大多数参与者（82%）认为电子烟并非完全安全，但认为它们比传统香烟的危害性小。60%的人认为电子烟具有成瘾性，但成瘾性低于传统香烟。
参与者主要将电子烟作为戒烟辅助工具或传统香烟的替代品，大多数人报告说他们成功地戒烟了。需要更多关于电子烟安全性及其在减少伤害和戒烟方面的功效的数据。
