Existing clinical work inspecting the results of ECIG aerosol publicity on the human respiratory system additionally makes generalization difficult owing to numerous methodological variations. Expired nitric oxide (NO) ranges have been measured earlier than and after each session (NO is necessary for vasodilation and blood flow; cigarette people who smoke have lowered NO levels169). One study171 compared lung function and exhaled NO following smoking tobacco cigarettes or use of an open-system ECIG. Lung perform was not affected by use of ECIG or passive publicity for an hour.
