All of the education about the dangers of second-hand smoke seems to be working -- the number of kids exposed to smoke while riding in cars has dropped dramatically.
WebMD reports that according to the report published in the journal Pediatrics, 30% of teenagers said they were exposed to smoke in a car "within the past seven days" in 2009. In 2000 that figure stood at 48%
Over the decade much has been made about exposure to second-hand smoke. Four states -- Arkansas, California, Louisiana and Main -- have gone so far as to outlaw smoking in a car when a child is present.
"The implementation of a smoke-free motor vehicle policy represents the most effective way to protect youth from secondhand smoke exposure in this environment," the researchers said.
