Teen vaping could reverse progress in the control of tobacco

A new study debunks the popular belief that electronic cigarettes are merely a substitute for cigarettes among teens. Instead, the study suggests that some teens who never would have smoked cigarettes are now vaping. In 2014, about 14 percent of 12th-graders said they had either smoked or vaped. A decade earlier — before e-cigarettes were sold in the United States — 9 percent of surveyed teens in this age group reported that they had smoked.
