E-cigarettes are battery operated devices that deliver a nicotine high similar to conventional cigarettes by heating nicotine in a disposable cartridge and producing a vapor that can be inhaled. E-cigarettes are marketed as a less-harmful alternative to cigarette smoking, but not enough is known about the health effects of "vaping". In samples taken by FDA's Division of Pharmaceutical Analysis, one leading brand of e-cigarettes was found to contain diethylene glycol, a toxic chemical found in antifreeze. Several other samples were found to contain carcinogens, including nitrosamines. In spite of FDA's concern, e-cigarettes currently exist in a legal no-man's land. The FDA does not regulate the manufacturing, marketing, or sales of these products. E-cigarettes are sold without any warning labels and without any legal age restriction.
Another major concern is that e-cigarettes are intentionally marketed to young people with kid-friendly flavors such as bubble gum, gummy bear, chocolate, cherry crush, and coca-cola. In a 2013 report, the Centers for Disease Control and Prevention (CDC) reported that e-cigarette use more than doubled among middle and high school students. Tobacco giants Altria Group, Inc., Lorillard, and Reynolds American have taken note of the market success of e-cigarettes and are introducing their e-cigarette versions nationwide. Consumer advocates worry that e-cigarettes are being used by the tobacco industry as an addictive gateway to other tobacco products.
Increasingly, cities (including Boston, Chicago, New York and Los Angeles) and states (including New Jersey, North Dakota, and Utah) are moving to fill the federal regulatory gap by taking steps to regulate the sale and public use of e-cigarettes. In the fall of 2013, attorney generals from 40 states called on the FDA to regulate e-cigarettes to address their marketing, ingredients, and sale to minors. FDA has responded with a proposed rule to include emerging tobacco products such as e-cigarettes, nicotine gels, and certain dissolvable tobacco products under the Tobacco Control Act. Until a final rule is passed, however, consumers are on their own.
