Strong limits on marketing and sales are needed to control and prevent teens' use of electronic cigarettes, a new American Academy of Pediatrics (AAP) policy statement says.
Teens who use e-cigarettes are more apt to use traditional cigarettes eventually, studies show.
The surge in vaping among American teens threatens to turn back five decades of public health gains in reducing tobacco use, the AAP warned.
"Nicotine is highly addictive, and we know that the earlier that someone uses nicotine products in childhood, the more difficult it is to quit later," said Dr. Brian Jenssen, lead author of the new policy statement. He is a primary care pediatrician at Children's Hospital of Philadelphia.
"Most adult smokers started using tobacco before age 18," Jenssen said in an AAP news release.
The policy statement calls on federal officials to take immediate action to restrict marketing and sales of flavored vaping products to youth.
It appears in the February print issue of the journal Pediatricsand was published online Jan. 28.
Along with the risk of addiction, nicotine can do long-term damage to teen brain development, according to the AAP.
In 2018, nearly 21 percent of high school students and 5 percent of middle schoolers said they'd used an e-cigarette in the past month, according to the National Youth Tobacco Survey. That's up 78 percent from 2017.
More than 28 percent of middle and high school students -- about 20.5 million -- were exposed to e-cigarette ads from at least one source in 2016.
"E-cigarettes need stronger federal regulations to prevent youth access and use," said Dr. Susan Walley, co-author of the policy statement.
"The research is clear that teens are at higher risk of transitioning to traditional cigarettes even with experimental use of e-cigarettes," she said. Walley leads the AAP Section on Tobacco Control.
The statement calls on the U.S. Food and Drug Administration to immediately ban sale of e-cigarettes to people under age 21; prohibit online sale of vaping devices and solution; ban certain flavors including menthol, and ban ads and promotions that can reach youth.
The AAP also says e-cigarettes should be included in current tobacco-free laws that apply in places where kids live, learn, play, work and visit.
