There are significant adverse cardiorespiratory and immunological changes from e-cigarette use.

Keith R, Bhatnagar A. Cardiorespiratory and Immunologic Effects of Electronic Cigarettes. Curr Addict Rep. 2021 Mar 5: 1–11. “In summary, the weight-of-evidence discussed above warrants the view that the use of e-cigarettes has multiple adverse health effects. Acute use of e-cigarettes leads to an increase in heart rate and blood pressure, as well as obstruction of conducting airways, and arterial stiffness. Flow-mediated dilation is diminished, transcutaneous oxygen tension is decreased, and a characteristic immune response is activated. Chronic use of e-cigarettes has been found to be associated with a shift in cardiac autonomic balance towards sympathetic predominance and dysregulation of immune-related genes.”
