The CDC has found that secondhand smoke exposure is common among US teens, even if they have never used tobacco themselves. The primary locations for exposure are their homes and family cars.
Half of the teens in the USA are exposed to secondhand smoke, despite laws that ban smoking in public places. Researchers examined data from over 18,000 middle school and high school students, and found that 48 percent reported secondhand smoke exposure in 2013.
“The findings weren’t really a surprise as much as a call for public health action,” said study author Brian King, deputy director for research translation in the U.S. Centers for Disease Control and Prevention’s Office on Smoking and Health.
“The continuing research [on secondhand smoke] really helps us put a finger on who’s exposed and in what location,” he said. Teens whose families had no smoking rules in their homes and cars were exposed to less secondhand smoke, as could be expected.
The study was published online in the journal Pediatrics.
