Summary

This study looked at the lungs of 104 young Egyptian adults who had used e-cigarettes for at least six months. Researchers measured how well their lungs worked using a breathing test called spirometry. The goal was to see if e-cigarette use is linked to any changes in lung function, even in people without prior lung disease.
