WASHINGTON, Jan. 23 (Xinhua) -- E-cigarettes, widely promoted as an alternative to smoking, are actually attracting young people who might not otherwise have smoked tobacco products, a new U.S. study suggested Monday.
E-cigarettes are thought by some to be responsible for a decline in American youth cigarette smoking, but researchers from the University of California, San Francisco (UCSF) indicated the reality is the opposite.
The USCF researchers concluded that many kids who went on to smoke regular cigarettes may not have used nicotine at all if e-cigarettes did not exist.
"We didn't find any evidence that e-cigarettes are causing youth smoking to decline," said lead author Lauren Dutra of the UCSF.
"While some of the kids using e-cigarettes were also smoking cigarettes, we found that kids who were at low risk of starting nicotine with cigarettes were using e-cigarettes," Dutra said. "Recent declines in youth smoking are likely due to tobacco control efforts, not to e-cigarettes."
The findings, published in U.S. journal Pediatrics, built on a growing body of evidence that adolescents who start with e-cigarettes are more likely to subsequently smoke traditional cigarettes.
For the study, researchers examined data from more than 140,000 middle and high school students who completed a U.S. government tobacco survey between 2004 and 2017.
They found that cigarette smoking among U.S. adolescents declined during that decade, but did not decline faster after the advent of e-cigarettes in the U.S. between 2007 and 2009.
