The aftertaste is much like that of a breath candy. They are a mixture of fine tobaccos and clove spice, rolled into a cigarette. Most tobacco stores carry clove cigarettes. Try the local mall. Some convenience stores carry them, but not the major chains.
Cloves are cloves.
They contain a large amount of tobacco and a small amount of clove spices. In fact, the tobaccos used in clove cigarettes are usually superior to the tobaccos used in typical American cigarettes. However, I personally suspect that they contain less nicotine than regular cigarettes, because clove smokers tend to smoke less often and quit more easily than smokers of regular cigarettes. The primary difference is simple. Clove cigarettes contain cloves.
