Electronic cigarettes, often called e cigarettes, are battery operated devices designed to look like regular tobacco cigarettes. Like their conventional counterparts, electronic cigarettes contain nicotine. Here’s how they work An atomizer heats a liquid containing nicotine, turning it into a vapor that can be inhaled and creating a vapor cloud that resembles cigarette smoke.

Manufacturers claim that electronic cigarettes are a safe alternative to conventional cigarettes. However, the Food and Drug Administration (FDA) has questioned the safety of these products. When the FDA analyzed samples of two popular brands, they found variable amounts of nicotine and traces of toxic chemicals, including known cancer causing substances (carcinogens). This prompted the FDA to issue a warning about potential health risks associated with electronic cigarettes.

Until more is known about the potential risks, the safe play is to say no to electronic cigarettes. If you’re looking for help to stop smoking, there are many FDA approved medications that have been shown to be safe and effective for this purpose.

Q What are electronic cigarettes?

A Electronic cigarettes are products designed to deliver nicotine or other substances to a user in the form of a vapor. Typically, they are composed of a rechargeable, battery operated heating element, a replaceable cartridge that may contain nicotine or other chemicals, and an atomizer that, when heated, converts the contents of the cartridge into a vapor. This vapor can then be inhaled by the user. These products are often made to look like such products as cigarettes, cigars, and pipes. They are also sometimes made to look like everyday items such as pens and USB memory sticks, for people who wish to use the product without others noticing.

Q What concerns does FDA have regarding electronic cigarettes?

A FDA has not evaluated any e cigarettes for safety or effectiveness. When FDA conducted limited laboratory studies of certain samples, FDA found significant quality issues that indicate that quality control processes used to manufacture these products are substandard or non existent. FDA found that cartridges labeled as containing no nicotine contained nicotine and that three different electronic cigarette cartridges with the same label emitted a markedly different amount of nicotine with each puff. Experts have also raised concerns that the marketing of products such as e cigarettes can increase nicotine addiction among young people and may lead kids to try other tobacco products.
