The invention discloses a method for selectively reducing specific nitrosamines in cigarette smoke. The method is used for selectively reducing the specific nitrosamines in the cigarette smoke by the aid of chitosan-cyclodextrin-glutaraldehyde polymers. The chitosan-cyclodextrin-glutaraldehyde polymers are used as additives of cigarette filters, and are utilized when the cigarette filters are manufactured, so that the specific nitrosamines in the cigarette smoke are selectively reduced when a smoker smokes cigarette. The method has the advantages that releasing amounts of specific nitrosamines substances, such as NNN (N-nitroso-nornicotine), NNK [4-(N-methyl-N-nitrosamine)-1-(3-pyridyl)-butanone], NAT (N-nitroso-anatabine) and NAB (N-nitroso-anabasine) which are contained in tobacco, in the cigarette smoke can be obviously reduced; and a chitosan-cyclodextrin-glutaraldehyde polymer adding mode is simple, and the chitosan-cyclodextrin-glutaraldehyde polymers can be added during manufacture for filter sticks and are convenient to operate.
