The goal of this study is to evaluate the toxicant properties and predicted health effects of cigarillo and hookah tobacco products compared to cigarettes. Study aims are: (1) to characterize the hazardous chemicals linked to cancer and cardiopulmonary diseases in aerosols from eight common hookah tobacco products using standardized cytotoxicity, mutagenicity, and genotoxicity assays; (2) to evaluate complete and fractionated (particles and gas only) aerosols generated from cigarettes, cigarillos, and hookah products in lung epithelial cells, cardiac cells, and endothelial cells using short-term assays and biomarkers (cytokines, DNA adducts); and (3) to evaluate the adaptive responses of lung epithelial cells in response to treatment of cells for four weeks with aerosols from one of each type of tobacco product. Findings will indicate new information about the potential respiratory and cardiac health effects associated with cigarillo and hookah use.
