Nearly one in three high school students has reported using a tobacco product recently, according to a new federal survey released on Thursday, evidence that concerns over nicotine addiction among teenagers are not limited to e-cigarettes.

“The data released today on youth tobacco product use are deeply troubling and indicate that past progress in reducing youth use of these products has been erased,” said Brian King, the deputy director of the Office on Smoking and Health at the Centers for Disease Control and Prevention. “These troubling rates of use are being driven by e-cigarettes, which have no redeeming aspects among youth.”

For the sixth year in a row, e-cigarettes dominated the students’ choice. Public health officials were concerned that despite wide-scale publicity intended to deter vaping, especially in the wake of recent vaping-related illnesses and even deaths, not only did the practice continue to surge, but students also did not seem to be particularly alarmed about e-cigarettes.

And while e-cigarettes were by far the most popular product, researchers noted that one in three users, or an estimated 2.1 million middle and high school students, also used an additional tobacco product, such as cigars and cigarettes. Those students reported more symptoms of nicotine addiction than those who used one tobacco product.
