The invention discloses a method for reducing tar of cigarette products. The method includes the steps: firstly, slicing flue-cured tobacco laminas, absorbing moisture, regaining the moisture, loosening the flue-cured tobacco laminas, regaining the moisture, blowing atomized water into the flue-cured tobacco laminas, baking the flue-cured tobacco laminas and blowing atomized water into the flue-cured tobacco laminas again; secondly, shredding the flue-cured tobacco laminas, and then drying, perfuming and rolling shreds. After tobacco leaves are repeatedly baked and regain the moisture, substances in blades and liquid can be promoted in browning reaction and sugar caramelization while unpleasant odor of the tobacco leaves is removed, so that flavoring substances are generated, inherent fragrance of the tobacco leaves diffuses, the content of chemical components of flue-cured tobaccos is changed, the nicotine content of the flue-cured tobaccos is reduced, the potassium-chlorine ratio of the flue-cured tobaccos is increased, combustibility of the flue-cured tobaccos is improved, and the tar release amount of the flue-cured tobaccos can be reduced. Compared with an existing process, the method has the advantage that indexes such as reducing sugar, nicotine, chlorine, potassium and total nitrogen are consistently changed. The combustibility of the tobacco leaves is enhanced, so that the tar release amount of cigarettes can be controlled. The tar yield of the cigarettes is reduced, the nicotine and carbon monoxide are reduced to varying degrees, and harm of the cigarettes to a human body can be remarkably decreased.
