SECONDHAND SMOKE EXPOSURE IN CARS
CHILDREN AND ADULT PASSENGERS ARE AT RISK
Exposing passengers, both children and adults, to secondhand smoke in the confined space of a car is extremely hazardous. Everyone should be encouraged not to smoke in vehicles. This exposure is hazardous to anyone’s health, but in particular to children whose smaller bodies proportionally take in a larger volume of air.
When someone smokes in the small enclosed space of a car or other vehicle, people breathe toxic air at levels many times higher than what the EPA considers hazardous, even when a window is down. Additionally, the gases and particulates of tobacco smoke absorb into the upholstery and other surfaces inside a car—which is called thirdhand smoke—and it then re-emits back into the air over time, which exposes passengers to toxins long after anyone actually smoked in the car.
As awareness increases that there is no safe level of exposure to secondhand smoke, and that people are regularly exposed in vehicles, some policymakers have decided to take action to reduce exposure in cars with children and in work vehicles.
Because a law, by itself, is unlikely to eliminate secondhand smoke exposure in cars, ANR Foundation recommends that any smokefree car campaign be accompanied by a strong education effort, stressing the health hazards of smoke-filled vehicles. Campaigns for smokefree car laws can serve as a tool to educate the public about the health hazards of secondhand smoke exposure and improve decision making about smoking in ways that harm other people.
