Household e-cigarette exposure linked to poorer pediatric asthma control

A study presented at the American Academy of Pediatrics 2026 National Conference & Exhibition indicates that household exposure to e-cigarettes is linked to poorer asthma control in children. Analyzing 48,118 pediatric primary care encounters from an urban health network between July 2023 and March 2026, researchers found that e-cigarette-only exposure was associated with increased asthma flares and activity-related symptoms.

The findings challenge the assumption that e-cigarettes are a significantly lower risk to children's health compared to combustible tobacco. While combined exposure to both traditional tobacco and e-cigarettes showed the broadest negative impacts—including higher albuterol use and increased hospital admissions—e-cigarette-only exposure showed symptom associations comparable to combined exposure.

Dr. Brian Jenssen of the Children's Hospital of Philadelphia emphasized that “there is no safe level of tobacco or e-cigarette exposure when it comes to children.” Researchers are urging pediatric care teams to screen for all forms of household nicotine and tobacco use during routine clinical visits.
