Reasons for current e-cigarette use among U.S

An e-cigarette is an umbrella term for an electronic device that delivers nicotine and other products including flavourings E-cigarettes are battery-operated devices with an element and a tank for e-liquid that is heated to allow people to inhale an aerosol The aerosol arising from the carrier solvents (humectants) typically (although not always) contains nicotine, flavourings, and other chemicals (metals and volatile organic compounds) Other terms used to identify e-cigarettes include e-vaporisers, or electronic nicotine delivery systems (ENDS), e-hookahs, hookah pens, vapers, vape pens, and mods (short for modifiable devices) Mods are customisable e-cigarettes and contain more powerful vaporisers than earlier e-cigarette models Although there are variations in the appearance of e-cigarettes, the National Institute on Drug Abuse has reported that regardless of their design and appearance, the devices generally operate in a similar manner and are made of similar components
