Abstract
Cigarette sidestream smoke can have the aroma thereof altered by placing the cigarette wrapping paper in intimate contact with a flavor precursor such as ethyl vanillin glucoside. The cigarettes exhibit good tobacco taste during use. The flavor precursor provides no substantial aroma to the cigarette prior to use thereof, and a characteristic aroma of the flavoring agent in the sidestream smoke during use thereof. Cigarettes can have a wrapping paper containing magnesium oxide and/or magnesium hydroxide, the paper having a net permeability of greater than 50 CORESTA units and an inherent permeability of less than 45 CORESTA units. The paper containing magnesium oxide and/or magnesium hydroxide is in intimate contact with a flavor precursor, and the filter of the cigarette includes a flavor carrier such as a flavored pellet.
