"Tobacco use in any form, including e-cigarettes, is unsafe for youth", said Corinne Graffunder, the director of the CDC's Office on Smoking and Health.
Adolescent cigarette smoking has been falling for many years, but the decline in e-cigarette and hookah use was more remarkable.
On June 15, the U.S. Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) released new data regarding the number of tobacco users among middle and high school students.
The number of teenagers using e-cigarettes fell from 3 million in 2015 to 2.2 million in 2016, according to a report published Thursday in Morbidity and Mortality Weekly Report.
In the 2015-2016 survey, among high school students, decreases were reported in current use of any tobacco product, any combustible product, use of two or more tobacco products, e-cigarettes, and hookahs. These yearly surveys are given to middle and high school students in the US, who then voluntarily complete the printed questionnaire.
Cigarette use among high school students fell during that period to 8 percent from 15.8 percent while use of cigars fell to 7.7 percent from 11.6 percent. It is also clear from these most recent numbers that youth are continuing to experiment with, or becoming regular users of, a wide range of other tobacco products.
"Although e-cigarette aerosol generally contains less harmful ingredients than secondhand smoke, it is not harmless; safer is not the same thing as safe", King said by email.
Myers, of Tobacco-Free Kids, said that the report's good news "is balanced by the fact that the very regulatory structure and programs that have helped bring it about are now being threatened".
The charges against Bill Cosby, and sentences they carry
Constand initially settled the case with a civil suit in 2006, having waited a year to report the alleged assault to the police. In those interviews, Cosby admitted to sexual contact with Constand and said they had previously had a romantic encounter.
Public health officials attribute the overall decline in tobacco to higher prices, access restrictions and laws prohibiting its use in certain areas. "They are the most commonly used tobacco products among youth in the USA, with more than 2.2 million youths using them". "If however, he vigorously implements them even while exploring whether e-cigarettes can help adults quit, he has the potential to turn the current trend into an irreversible movement".
That jumped to 16 percent in 2015, and it's become more common than cigarette smoking.
After the increase in the use of e-cigarettes by young people until 2015, public health authorities were alarmed by the numbers, said King.
"Given budget cuts to public health and tobacco cessation in North Carolina, the challenge will be to continue this trend", said Dr. John Spangler, a professor of family and community medicine at Wake Forest Baptist Medical Center.
Studies suggest many children who vape use the products less often than children who smoke cigarettes - a sign that vaping seems to be more social and experimental, experts said. They claim vaping companies deliberately sell flavors that appeal to kids in order to hook them on nicotine early and claim vaping is a gateway for teens to smoking.
We plan to build on these vital efforts to reduce tobacco-related disease and death. "If we backslide, these gains will only be temporary".
