In the latest Keeping Kids Healthy column by UTMB Drs. Sally Robinson and Keith Bly: One electronic cigarette can have as much nicotine as a whole pack of cigarettes. In addition, the Food and Drug Administration has found cancer-causing chemicals in electronic cigarettes. E-cigarette usage has doubled among middle and high school students. A survey by the Centers for Disease Control and Prevention found that about 1 in 10 high school students admitted using an e-cigarette. E-cigs are not regulated or approved by the FDA and do not have to follow the same rules as other nicotine products. This means that the amount of nicotine and other harmful ingredients in each cartridge is not always the same. In addition, it is easy for children to buy e-cigs. More than half of the states allow children of any age to purchase e-cigarettes, and they’re easy to get online and in mall booths. The American Academy of Pediatrics urges parents to talk with their children about the dangers of e-cigarettes.
