In fact, combined e-cigarette and cigarette use among adolescents in 2014 was higher than total cigarette use in 2009, they stated.
“The study didn’t find any evidence that e-cigarettes are causing youth smoking to decline,” added Lauren Dutra, social scientist at RTI International — a not-for-profit research organisation based in North Carolina, US.
The “recent declines in youth smoking are likely due to tobacco control efforts, not to e-cigarettes,” Dutra noted.
For the new study, the team examined survey data from more than 140,000 middle and high school students who completed the CDC’s National Youth Tobacco Survey between 2004 and 2014.
The results showed that cigarette smoking among US adolescents declined during that decade, but did not decline faster after the advent of e-cigarettes in the US between 2007 and 2009.
