Electronic Nicotine Delivery Systems (ENDS), of which electronic cigarettes are the most common prototype, are a recent development in tobacco harm reduction. The Oxford Dictionary named "vape" the 2014 word of the year, marking the rise of a billion-dollar electronic-cigarette industry. E-cigarettes, also known as e-vaping devices, were introduced to the Chinese market in 2004 and to the US market in 2007 and are now becoming popular in India.
Studies have revealed that e-cigarettes are not free from adverse effects, and the use of e-cigarettes by teenagers, especially middle-school children, has increased, resulting in the criticism of e-cigarettes worldwide. There are two views: some experts welcome ENDS as a pathway to the reduction of tobacco smoking, while others do not support their use, hence ENDS are the subject of a public health debate. Currently the use of e-cigarettes is apparently booming as “gateway devices” for smoking among young people. There is a need for well designed studies & pharmacovigilance programme for Electronic Nicotine Delivery Systems.
