In some high schools in the United States, e-cigarettes are almost as ubiquitous as Instagram and Snapchat. “They will sneak a sneak peek,” says a second-year student who smokes e-cigarettes in the back of the classroom, in the bathroom, and “anywhere” that you can think of at school. Electronic cigarettes do not produce a strong odor, so it is difficult for teachers to know when students use these devices.
A popular brand, Juul, a flash-like drive that offers mango and cucumber-flavored nicotine cartridges - e-cigarettes have become a fashion for teenagers across the country, and public health officials are shocked. According to a 2016 report by US surgeons, the proportion of high school students using e-cigarettes has increased by 900% in recent years.
Experts say this trend is likely to erode the hard progress that has been made in suppressing youth smoking for decades. Researchers also say that these e-cigarette devices not only contain high concentrations of nicotine, but are also more easily absorbed by the body. There is also evidence that the use of e-cigarettes increases the risk of adolescents starting to smoke traditional cigarettes.
