MILWAUKEE (the Patch) — Eight teenagers were hospitalized with seriously damaged lungs in July at Children’s Hospital, and state health officials say each of the cases involves vaping.

The state is currently investigating the possible causes of these illnesses, but all patients reported vaping in the weeks and months prior to being hospitalized. “While an exact cause is unknown, the number of patients in such a short time frame is concerning,” Children’s Hospitals officials said Thursday morning. “With the increase in use of e-cigarettes and vaping, parents and teens need to be aware of the potential danger.”
