Electronic cigarettes (e-cigarettes or e-cigs), known formally as electronic nicotine delivery systems (ENDS),
are devices designed to look similar to cigarettes in shape, size, and general appearance. They operate by
vaporizing a solution containing nicotine, creating a mist that is then inhaled.1 The tips of these devices often
have an indicator light, designed to emulate the burning ash of a traditional cigarette.1 According to product
manufacturers, e-cigarette cartridges are available in various flavors, such as vanilla,2 menthol,2 and piña
colada,2 and varying claimed levels of nicotine.1 Using an e-cigarette is commonly referred to as “vaping.”1
Popular brands of e-cigarettes, sold at convenience stores and gas stations, include “blu” and “NJOY.”
