  • Despite being tested with a more intense puffing regime, e-cigarette aerosol showed no acute cytotoxicity in this study when compared with traditional 3R4F reference cigarette smoke.
  • Under the study conditions cigarette smoke demonstrated a dose-dependent response that resulted in near-complete cell death after a 6 h exposure period. In contrast, e-cigarette aerosol showed no decrease in tissue viability following a 6 h exposure, despite appropriate positive control responses. Furthermore, cytotoxicity appears to be unaffected by different e-cigarette formulations as tested in this study.
