A new government reports says vaping held steady last year among high school students, but some researchers are skeptical because the survey may have missed out on a booming e-cigarette brand.
The Centers for Disease Control and Prevention survey did not specifically ask about Juul e-cigarettes. And research suggests some kids don't equate the trendy devices with other types of e-cigarettes.
One researcher says given that omission and the skyrocketing sales of Juul last year, the survey may be missing a big part of what's going on.
E-cigarettes are battery-powered devices that provide users with aerosol puffs that typically contain nicotine, and sometimes flavorings like fruit, mint or chocolate. They're generally considered a less dangerous alternative to regular cigarettes, but health officials have warned nicotine is harmful to developing brains.
