Nicotine and total particulate matter (TPM) release from WS by machine smoking regimen. (A) Nicotine (μg/ml) release by number of puffs. Concentrations differed significantly between the ISO and HCI regimens (p = 0.0005). (B) Total particulate matter (μg/CFP) release by number of puffs. There was a statistical difference in TPM release between ISO and HCI exposure (p < 0.0001). Abbreviations: HCI, Health Canada intense regimen; ISO, International Organization for Standardization regimen; WS, whole smoke. Graphs were generated with GraphPad Prism 8 software and edited by using GIMP image manipulation program (version 2.10.14).
