The respiratory health effects of heated tobacco product aerosols in a primary human airway epithelial cell model

Heated-tobacco-products (HTPs) are electronic devices that "heat" a processed tobacco/chemical mixture to produce an inhalable emission. They are advertised as a reduced-risk alternative to cigarette smoking. The aim of our research was to assess their potential health impacts using a 3D human airway model.
