The number of teenage smokers is on the decline, but almost half of youth who have never smoked said they’ve been exposed to secondhand smoke in the last week, according to a new study by the Centers for Disease Control and Prevention [CDC].
The effects of secondhand smoke are widely recorded. According to a CNN article, “[c]hildren who are exposed to secondhand smoke are at increased risk of asthma, lung infection and ear disease, among other health conditions.”
The CDC study, published in the Pediatrics journal, was based on a survey of 18,000 middle and high schoolers about whether they have used “cigarettes, e-cigarettes, pipes, hookahs and chewing tobacco,” according to CNN.
They also responded to questions about whether they had been around someone who had used those products (sans e-cigarettes) in the past week.
Almost half of teenagers who never used tobacco products reported secondhand smoke exposure — 48 percent.
The most common places for exposure were public areas, including restaurants and parks, where about 35 percent of study participants reported being exposed. Another 17 percent and 27 percent were exposed at school and work, respectively. Although only 15 percent were exposed in their home and another 15 percent in cars, these were the most common sites for daily secondhand smoke exposure.
The American Academy of Pediatrics recommends raising the minimum nationwide smoking age to 21 to limit the availability of tobacco on school grounds.
The CDC study was able to determine where secondhand smoke exposure occurred, but it couldn’t link the amount of exposure to states with or without smoke-free laws.
CNN reports that 28 states and numerous communities ban smoking in public places, including restaurants and bars, and that about half of the country is covered by anti-smoking laws.
Some parts of California have banned smoking in all apartment buildings, and there are also states that “have some municipal laws that prohibit smoking in publicly owned apartment buildings.”
Eight states prohibit smoking in cars when youth are riding along, according to CNN.
CDC researchers determined secondhand smoke exposure comes from family and friends. Unsurprisingly, 80 percent of current smokers and 65 percent of former smokers have been exposed to secondhand smoke.
According to CNN, teenage girls are more likely to be around secondhand smoke while teenage boys are more likely to smoke themselves.
This fact-based local reporting drives impact and creates change. Help power that impact.
James Baldwin wrote, “Not everything that is faced can be changed, but nothing can be changed until it is faced.” PublicSource exists to help the Pittsburgh region face its realities and create opportunities for change. When we shine a light on inequity in our region, like the “completely unacceptable” conditions in low-income housing in McKeesport, things change. When we ask questions about policymakers’ decisions, like how Allegheny County is handling COVID-19 safety for its employees, things change. When we push for transparency on issues that affect the public, like in the use of facial recognition software by Pittsburgh police, things change.
