Electronic cigarettes, also known as electronic nicotine delivery systems (ENDS), were introduced over a decade ago and since 2010 the inhalation of e-cigarette vapor or ‘vaping’ has risen exponentially in both smokers and ex-smokers. There is a significant body of published material on ENDS/e-cigarettes and despite varying opinions, their main effects remain controversial. They may be a useful tool for reducing traditional cigarette smoking but for many, they are simply a replacement nicotine delivery method. As such they may precipitate a new public health problem. The public perception is that they are less of a health hazard than conventional cigarette smoking, yet the long-term effects of e-cigarettes remain to be elucidated. E-cigarettes have developed significantly in the last decade, increasing in complexity and capacity. They are now considered to be in the fourth generation, comprising highly modifiable devices capable of modulating the energy input used to generate vapor.
