A study reveals that 'clear' e-cigarettes in Massachusetts, introduced post-flavor ban, contain synthetic additives that heighten cardiovascular effects. Among 207 young adults, those using 'clear' e-cigarettes experienced more significant increases in heart rate and blood pressure compared to non-users and flavored e-cigarette users. The analysis detected synthetic cooling agents and other flavorants in 'clear' products. Researchers from Boston University stress the need for further investigation into the cardiovascular impacts of these products.
