About 11% of children between 13 and 15 smoke, according to a global survey reported by Reuters. 

For the current study, researchers examined data from surveys of teens in 61 countries conducted from 2012 to 2015. Half of nations had a smoking rate of at least 15 percent for boys and at least 8 percent for girls, they found.

“Smoking has been shown to harm nearly every organ of the body, and science shows that most adult smokers first start smoking during adolescence,” said lead study author Rene Arrazola of the Office on Smoking and Health at the CDC.

“Young people who begin to smoke at an earlier age are more likely than those who start at older ages to develop long-term nicotine addiction,” Arrazola said by email. “Therefore, efforts to prevent youth tobacco use are critical to prevent another generation of adults who smoke and suffer from smoking-related death and disease.”
