According to a poll, 2 million American teenagers smoke marijuana

A school survey shows that nearly one in 11 American students have used marijuana in electronic cigarettes, which has heightened concerns about the new popularity of teen smoking.

Electronic cigarettes generally contain nicotine, but results published on Monday mean that 2.1 million high school students used them to achieve high scores.

Devices are generally considered a less dangerous alternative to regular cigarettes, despite little research on their long-term effects, including the fact that they help smokers quit smoking.

The increase in the number of teenagers who use them has alarmed health officials. Last week, the Food and Drug Administration granted the five largest electronic cigarette manufacturers 60 days to develop plans to end the minor use of their products.

According to the report published Monday in the journal JAMA Pediatrics, nearly 9% of students surveyed in 2016 reported using an electronic device containing marijuana. This included one-third of those who had already consumed electronic cigarettes.

The number is worrisome "because cannabis use among young people can negatively affect learning and memory and can affect school results and education," said Principal Researcher Katrina Trivers of the Centers for Disease Control and Prevention.

Students who reported living with a tobacco user were more likely than others to report using marijuana.

It is not known whether marijuana use increases in adolescents or is stable. Appliances have become a multi-billion industry, but they are relatively new.

It was the first time that a question about marijuana steam was asked as part of this survey, which uses a sample of nationally representative students in public schools and schools. private. More than 20,000 students responded to the survey in 2016.

Another survey by the University of Michigan in December yielded similar results when it first asked for information on marijuana. In this study, 8% of Grade 10 students reported having sprayed marijuana in the last year.

"The health risks associated with vaping reside not only in vaping devices, but also in the social environment that accompanies it," said Richard Miech, a researcher at the University of Michigan. Children who are being swallowed are more likely to become known as drug users and to become friends with drug addicts, he added.
