Vaping during pregnancy causes long-term lung effects in mouse offspring
In the study, pregnant mice were exposed to e-cigarette vapor with nicotine, e-cigarette vapor without nicotine, or filtered air. The researchers examined the offspring at five months of age and found reduced lung function and signs of startling in mice exposed to e-cigarette vapor with or without nicotine. They also found that the female mice had a significantly higher body weight as adults, but not at birth. The research has been published in The American Journal of Physiology-Lung Cell and Molecular Physiology.
Most e-cigarettes contain nicotine, an addictive drug that can damage a baby’s brain, lungs and other developing organs. They also contain chemicals, flavorings and other additives that can negatively impact health. In a 2015 study, about 7% of women said they vaped while pregnant, despite warnings from the Centers for Disease Control and Prevention.
The e-cigarette market has continued to grow exponentially and is expected to exceed $60 billion worldwide by 2025, outpacing sales of traditional cigarettes. As of 2014, e-cigarettes have been the most widely used tobacco product among young Americans, according to the CDC.
Next, Ohio State researchers will examine whether people exposed to vaping in utero will develop more harmful lung diseases as they age, especially when they experience other lung problems such as asthma or infection.
