E-cigarettes: US FDA caution

Lyndsey Layton, Washington Post , Wednesday, July 22, 2009 reports the US Food and Drug Administration (FDA) found that an analysis of leading brands of electronic cigarettes (new type of "smokeless" nicotine product) showed carcinogens and a chemical used in antifreeze that are toxic to humans.

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. Since they produce no smoke, they can be used in workplaces, restaurants and airports. The products are relatively new and began appearing on the market about five years ago, sold over the internet, in mall kiosks and in stores. They often come in candy and fruit flavors.

The FDA and other public health experts cautioned consumers against using the products, saying that the health effects of electronic cigarettes are unknown.

The FDA studied the ingredients in the sample cartridges of electronic cigarettes. In one sample, it detected diethylene glycol, a chemical used in antifreeze. Other samples turned up carcinogens, including nitrosamines.

The FDA considers e-cigarettes to be drug devices and says that manufacturers must first get federal approval to market them. It has refused to allow imports of e-cigarettes
