What this trial studies

This study examines how switching from menthol cigarettes to non-menthol cigarettes affects biomarkers of systemic inflammation and smoking behavior. A total of 68 menthol cigarette smokers will participate in a five-week study, starting with a one-week baseline period of menthol smoking, followed by four weeks of smoking non-menthol cigarettes. Blood samples will be collected at various points to analyze inflammation and tobacco exposure, while participants will also report their smoking patterns and subjective responses using a smartphone application. The study aims to provide insights into the health implications of menthol cigarette use and the effects of switching to non-menthol options.

Who should consider this trial

Good fit: Ideal candidates are men and women aged 21-85 who currently smoke menthol cigarettes and have a daily smoking rate of at least 5 cigarettes for over a year.

Not a fit: Patients who are currently pregnant, actively trying to quit smoking, or have a history of severe medical or psychiatric conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help inform smoking cessation strategies and public health policies regarding menthol cigarette use.

How similar studies have performed: While there is ongoing research into the effects of menthol cigarettes, this specific approach of switching cigarette types to assess inflammation biomarkers is relatively novel.
