Electronic Cigarettes and Alternative Nicotine Products
By Karmen Hanson | Vol . 22, No. 26 / July 2014
Electronic cigarettes are making headlines across the country, and e-cigarette sales are estimated to top $2 billion in 2014. Also known as digital cigarettes or “e-cigs,” electronic cigarettes are battery-operated devices used to inhale vaporized liquid, often called e-liquid or ejuice, from cartridges. Most cartridges contain nicotine, and some have flavorings and other ingredients, such as food-grade propylene glycol to act as a propellant. Although designs vary widely, e-cigarettes consist of a plastic or glass tube and often resemble a traditional combustible cigarette or a larger pipe-like device. They may be single-use or refillable, and many versions are on the market. The technology in each cigarette or pipe may be either relatively simple or complex to control the amount of liquid vaporized per puff or number of puffs per cartridge. The products generally are marketed as alternatives to combustible cigarettes or as an alternative nicotine delivery device that does not produce traditional secondhand smoke.
