Background: Awareness and use of electronic cigarettes (e-cigs) has increased significantly in the past five years, but little is known about the experiences, satisfaction, opinions and preferences of e-cigs users. Method: 1177 participants completed an online survey about their electronic cigarette preferences, of which 200 were randomly selected for analysis. The data were analyzed using both qualitative and quantitative methods. Results: Participants found the design, the ability to customize, and the quality of vapour to be the most important characteristics of the device. Participants thought the most positive aspects of e-cig use were help to quit smoking, improved overall health, and reduced cost. The negative aspects associated with its use were mainly related to side effects, such as dry mouth. When asked to explain how e-cigs were used differently than cigarettes, participants reported puffing more regularly, but taking fewer puffs per session. Conclusions: Experienced e-cig users stated that initiating e-cig use helped them to quit or reduce their conventional smoking, which they believe reduced their health risks. In comparison to cigarette smoking, e-cig users reported using their e-cig more times per day, but with fewer puffs at each use time. Users acknowledged that more research is needed to understand the safety and long-term effects of its use. They mentioned dry mouth as a common side effect and common problems with reliability of e-cigs. Understanding these views may help health professionals to assess and assist e-cig users, and in the future, may help regulators to improve quality and reduce risks.
