Summary

This study looks at how long-term e-cigarette use impacts the health of tiny blood vessels (microvascular health) in young adults aged 18 to 29. Researchers will compare frequent e-cig users to non-users using non-invasive tests. The goal is to understand the body's response, not to provide treatment.
