Electronic Cigarettes (E-cigs) and Vaping

Electronic Cigarettes (e-cigs) and other "vaping" devices are battery-operated products designed to deliver nicotine, flavor and other chemicals. They turn chemicals, including highly addictive nicotine, into an aerosol that is inhaled by the user. Most e-cigs are manufactured to look like conventional cigarettes, cigars, or pipes. Some resemble everyday items such as pens and USB memory sticks, and are known as tanks, vape pens, vaporizers, and e-pipes.

According to the WHO 2014 E-Cigs Report, in 2014 there were 466 brands of e-cigs. In 2013, consumers spent $3 billion on e-cigs globally. Sales are forecasted to increase by a factor of 17 by 2030.(1) 

On May 5, 2016, the FDA asserted authority to regulate all tobacco products, including vaping devices.

Information is still being collected on risks, and potential benefits, of vaping. It is unclear at this point if e-cigs are an effective way to quit smoking. Research continues.

Current e-cigarette use among middle and high school students tripled from 2013 to 2014, according to data published by the Centers for Disease Control and Prevention and the U.S. Food and Drug Administration’s Center for Tobacco Products (CTP) in the Morbidity and Mortality Weekly Report (MMWR).(2) Findings from the 2014 National Youth Tobacco Survey show that current e-cigarette use (use on at least 1 day in the past 30 days) among high school students increased from 4.5 percent in 2013 to 13.4 percent in 2014, rising from approximately 660,000 to 2 million students. Among middle school students, current e-cigarette use more than tripled from 1.1 percent in 2013 to 3.9 percent in 2014—an increase from approximately 120,000 to 450,000 students.
