Hypothesis
What are the health effects of menthol cigarettes compared to non-menthol cigarettes?
Conclusion
Menthol is a biologically active compound that has effects by itself and in conjunction with nicotine, but much of the data on other areas of interest are inconclusive.
Supporting Evidence

- Black/African American smokers are more likely to smoke menthol cigarettes.
- Menthol may alter the metabolism of certain tobacco carcinogens.
- Data on menthol's effects on biomarkers of smoke exposure are inconclusive.
- Menthol does not appear to enhance the cytotoxicity of tobacco smoke.
Takeaway
Menthol cigarettes might be just as harmful as regular cigarettes, but we don't know for sure how they affect health.
