The research, published Jan. 21 in JAMA Pediatrics, was conducted by the anti-tobacco advocacy group Truth Initiative.
"Youth tobacco use is at its highest in nearly 20 years, primarily driven by e-cigarettes resulting in over 5 million youth now vaping across America," Robin Koval, CEO and president of Truth Initiative, said in a news release.
"Years of progress in the fight against youth tobacco [use] have been reversed," Koval added, "with millions of teens, most of whom were not smokers, now using a high-nicotine tobacco product."
