Effective today the Food & Drug Administration has banned clove and sweet flavored cigarettes. Due to industry pressure they did not do so with menthol flavored ones. Interestingly the article in USA Today quoted a researcher as stating "We all thought until quite recently that menthol was just a neutral flavor."
I guess they didn't do much research. Menthol to me was always minty and made smoking a cigarette much easier. They have also only been around for several dozens of years. I guess this is what passes for science now.
