The use of electronic cigarettes by US teenagers has dramatically risen this year, a new report says.
The percentage of 12th grade students, typically aged 17-18, who reported vaping nicotine rose to 21% from 11% in 2017, a survey by the University of Michigan said.
Researchers say the trend is reversing declines in the number of adolescents who use nicotine.
The survey asked students if they had vaped over the preceding 30 days.
What does the study say?
The Monitoring the Future study, based on interviews with 45,000 students across the country, said this was the largest single-year increase in its 44-year history, surpassing a surge in marijuana smoking in the 1970s.
It also said:
- Among 8th grade students, nicotine vaping increased from 3.5% to 6.1%
- The rate of use among 10th grade students rose from 8% to 16%
- For students in grades 9 through 12 the increases mean at least 1.3 million additional teenagers who vaped
- Marijuana vaping is also increasing
“The policies and procedures in place to prevent youth vaping clearly haven’t worked,” said Richard Miech, the survey’s lead author.
“Vaping is reversing hard-fought declines in the number of adolescents who use nicotine… These results suggest that vaping is leading youth into nicotine use and nicotine addiction, not away from it.”
There was no significant change in the use of alcohol, marijuana, cocaine and other popular drugs, the report said, while binge drinking saw a sharp decline in 2018 among 12th grade students.
The decline in cigarette smoking by teens showed some interruption this year.
What’s behind the rise?
It is hard to say exactly. Experts blame newer versions of e-cigarettes, some of them looking like USB drivers, that can be used discreetly, and the many flavourings available.
Another reason could be that more teenagers are staying at home, communicating on smartphones, and not hanging out with friends.
Vaping tends to be an individual activity, experts say, while drinking, smoking and drug experimentation are mostly done in groups.
“Factors that make vaping so attractive to youth include its novelty and the easy concealability of the latest vaping devices, which better allows youth to vape without adults knowing about it,” Mr Miech added.
