Electronic cigarettes (e-cigarettes) were introduced with a claim that they were a healthier alternative to tobacco smoking. Since then, the number of e-cigarette users has increased significantly because of the perception that they serve as a healthy substitute to tobacco consumption with minimal or no harm. Lack of usage regulations and the appealing nature of these devices are among other reasons for their popularity. Since their introduction in 2007, e-cigarettes have experienced widespread success among smokers, nonsmokers, females and youth. According to a recent estimate, their sales have increased by 14-fold since 2008.
