Summary

This study follows 172 adults over two years to compare cardiovascular function among four groups: vapers who previously smoked, vapers who never smoked, people who both vape and smoke, and ex-smokers who do not vape. Researchers measure blood vessel health, lung function, and blood markers of heart disease risk. The goal is to understand whether long-term vaping poses heart risks, especially for those who never smoked.
