The invention relates to a method for judging influence degree of different additive concentrations on conventional smoke indexes of cigarette, belonging to the technical field of cigarette. The method comprises the following contents: the test indexes are the conventional smoke indexes of the cigarette, such as total particulate matters, tar content, nicotine content, water content, and carbon monoxide content of the smoke; the test factors are additive concentrations; the additive concentrations are 0.0000%-0.5000%; test is carried out by selecting single-factor random design; and the test result processing is carried out by variance analysis, LSD (Least Significant Difference), Scheffe, Bonferroni, Sidak, Turkey, Hochberg's GT2 and Gabriel multiple comparison methods, so as to judge the influence degree of different additive concentrations on the conventional smoke indexes of the cigarette. In the application process, the method has the following advantages that the influence significance of the different additive concentrations on the conventional smoke indexes of the cigarette is judged, the influence trend is visually analyzed, and the difference between the conventional smoke indexes of the cigarette treated by different concentrations is inferred; the judgment and inference are scientific and reliable; and the method has the important practical significance in judging the efficacy of harm and tar reducing additives and improving the quality safety of cigarette products.
