NCT ID NCT06232447
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at what happens to markers of inflammation in the blood when menthol cigarette smokers switch to non-menthol cigarettes. The goal is to understand if removing menthol could lower heart disease risk. About 68 adult menthol smokers will be followed for several weeks. This is an observational study, not a treatment trial.
