Electronic hookah (e-hookah) bowls, which contain flavored e-liquid that is heated electrically but inhaled through traditional waterpipes, are increasing in popularity in the United States. The goals of this study are to compare the effects of traditional hookah smoking with e-hookah inhalation on human vascular and endothelial function, and to examine the role of inflammation and oxidative stress in hookah-related cardiovascular disease development. Study aims are: (1) to determine the acute effects of e-hookah bowl inhalation on endothelial function; (2) to determine the acute effects of e-hookah bowl inhalation on arterial stiffness; and (3) to determine the acute effects of e-hookah bowl inhalation on biomarkers of oxidative stress and inflammation. Researchers will conduct cross-over studies in 18 young adult hookah smokers (ages 21-39). Findings will provide new information about the effects of e-hookah use on human health and may inform regulatory activities related to e-hookah.
