The U.S. Food and Drug Administration today announced that a laboratory analysis of electronic cigarette samples has found that they contain carcinogens and toxic chemicals such as diethylene glycol, an ingredient used in antifreeze.
Electronic cigarettes, also called "e-cigarettes," are battery-operated devices that generally contain cartridges filled with nicotine, flavor and other chemicals. The electronic cigarette turns nicotine, which is highly addictive, and other chemicals into a vapor that is inhaled by the user.
These products are marketed and sold to young people and are readily available online and in shopping malls. In addition, these products do not contain any health warnings comparable to FDA-approved nicotine replacement products or conventional cigarettes. They are also available in different flavors, such as chocolate and mint, which may appeal to young people.
Public health experts expressed concern that electronic cigarettes could increase nicotine addiction and tobacco use in young people. Jonathan Winickoff, M.D., chair of the American Academy of Pediatrics Tobacco Consortium and Jonathan Samet, M.D., director of the Institute for Global Health at the University of Southern California, joined Joshua Sharfstein, M.D., principal deputy commissioner of the FDA, and Matthew McKenna, M.D., director of the Office of Smoking and Health for the Centers for Disease Control and Prevention, to discuss the potential risks associated with the use of electronic cigarettes.
"The FDA is concerned about the safety of these products and how they are marketed to the public," said Margaret A. Hamburg, M.D., commissioner of food and drugs.
Because these products have not been submitted to the FDA for evaluation or approval, at this time the agency has no way of knowing, except for the limited testing it has performed, the levels of nicotine or the amounts or kinds of other chemicals that the various brands of these products deliver to the user.
