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.
However, there are other differences. Almost all of them are made there, but a few brands are manufactured elsewhere. For example, the Nat Sherman Co. on Fifth Ave. Because pure tobacco doesn't burn by itself. Regular American cigarettes are usually filled with many chemicals and additives to enhance the burn speed.
