Comparison of the chemical composition of aerosols from heated tobacco products, electronic cigarettes and tobacco cigarettes and their toxic impacts on the human bronchial epithelial BEAS-2B cells

The electronic cigarettes (e-cigs) and more recently the heated tobacco products (HTP) provide alternatives for smokers as they are generally perceived to be less harmful than conventional cigarettes. However, it is crucial compare health risks of these different emergent devices, in order determine which product should preferred substitute cigarette. present study aimed composition emissions from HTP, e-cigs cigarettes, regarding selected or potentially compounds, their toxic impacts on human bronchial epithelial BEAS-2B cells. HTP emitted polycyclic aromatic hydrocarbons carbonyls amounts compounds aerosols were still higher e-cig vapours. Concordantly, aerosol showed reduced cytotoxicity compared cigarette smoke but had potential increase oxidative stress inflammatory response, a manner similar that smoke, after intensive exposures. In addition, increasing power impacted levels certain related stress. This provides important data necessary risk assessment by demonstrating might considerably e-cig.
