Total particulate matter or whole smoke generated from different test cigarettes under ISO or HCI regimens were assessed for cytotoxicity using the neutral red uptake cytotoxicity assay. Cytotoxicity among the test cigarettes were greater for whole smoke and the cytotoxicity was decreased going from ISO regimen to HCI regimen.
