Dear Colleagues,

Electronic cigarettes have been introduced to the market in recent years as smoking alternatives. Despite major concerns from public health authorities, they have gained tremendous popularity and acceptance by consumers, with sales growing exponentially every year. Users (commonly called “vapers”) have organized themselves through the development of internet forums and consumer associations. There is an important social aspect in electronic cigarette use. Such characteristics have never been observed in any other product in the tobacco harm reduction or smoking cessation area. However, there are a lot of questions that need to be answered, as well as confusions and misunderstandings that need to be clarified. Is there a potential for electronic cigarettes to be a breakthrough in tobacco harm reduction? Do they represent a gateway from or to smoking? Are they effective in promoting smoking reduction or as a complete substitution, and why? Is there a potential to cause harm, and at what level compared to smoking? How should they be regulated? These are crucial issues that need to be addressed. Therefore, I invite you to submit your research and opinion, in order to better understand and explore this new phenomenon.

Dr. Konstantinos Farsalinos
