Summary

This study used MRI scans and blood tests to see how a single use of an e-cigarette (with or without nicotine) or a tobacco cigarette affects blood vessel function and inflammation. 55 current smokers and vapers were compared to a group of non-smokers/non-vapers. The goal was to understand the immediate physical effects of these products, not to test a treatment.
