E-cigarettes, heat-not-burn and smokeless tobacco products

Abstract

An e-cigarette is a battery-operated device that allows the user to breathe in nicotine through a vapour. They are sometimes referred to as Electronic Nicotine Delivery Systems (ENDS) and this term also includes devices such as vapes, e-hookahs, e-pipes and e-cigars. These devices work by heating a liquid so that it turns into a vapour for the user to inhale, or 'vape'. Although the vapour may look like steam, it does not contain any water. The liquid is made from chemicals called propylene glycol and/or glycerine, and it can have different flavours and different amounts of nicotine, which the user can select. Unlike traditional cigarettes, the devices do not contain tobacco.
