Bethany O'Grady switched to electronic cigarettes two years ago. The 23-year-old started smoking regular cigarettes when she was 13, and says she was addicted.
Now a new report shows more young people are using e-cigarettes. The Center for Disease Control and Prevention says the number of middle school and high school students who tried electronic cigarettes doubled to nearly 2 million last year.
"The brains of middle schoolers and high schoolers are still developing," says CDC Director Tom Frieden, "and research shows that their brains are even more susceptible to nicotine addiction."
E-cigarettes heat a liquid solution into a vapor. Some contain nicotine and other additives.
The latest findings show close to 80 percent of young students using them are also using traditional cigarettes. The CDC says that suggests e-cigarettes may open the door to other tobacco products.
"One in five middle schoolers who smoke, only smoke e-cigarettes," Frieden said. "So it strongly suggests that many are starting off with e-cigarettes and progressing into traditional ones."
Because E-cigarettes are largely unregulated, the FDA says it doesn't know the long term effects of the products. But manufacturers argue their devices are a safe option for traditional smokers trying to kick the habit.
Bethany, though, says they worked for her.
"At the end of the day, I am not smoking," she said. "I'm not putting actual smoke into my lungs."
She hasn't had a traditional cigarette in two years, and says she never wants to go back.
