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. The tips of these devices often have an indicator light, designed to emulate the burning ash of a traditional cigarette. According to product manufacturers, e-cigarette cartridges are available in various flavors, such as vanilla, menthol, and piña colada, and varying claimed levels of nicotine. Using an e-cigarette is commonly referred to as “vaping.” Popular brands of e-cigarettes, sold at convenience stores and gas stations, include “blu” and “NJOY.”
Cartridges generally contain up to 20 mg of nicotine. Some users refill their own cartridges, which may be dangerous because it involves dealing with potentially dangerous concentrations of nicotine. Refill bottles contain up to seven grams of nicotine; the fatal dose of nicotine in adults is estimated at 30-60 mg while for children it is estimated at only 10 mg – or approximately four drops of a maximum strength refill solution. This risk is more consistent with nicotine-based pesticides rather than traditional tobacco products and pose a danger via inhalation, ingestion, and skin contact.
Between 6.4 and 7.1 percent of current smokers have used an e-cigarette, compared to use of e-cigarettes among non-smokers (less than 1 percent)
