SOLUTION: This smoking tool in which the filtering material is disposed is characterized by comprising a smoking tool head portion in which a receiving space for the insertion of the tobacco is formed and at whose one end a connection port communicating with the receiving space through a vent is disposed, a mouthpiece at whose one end a connection port is formed, and a smoking tool intermediate portion whose both end portions are connected to the smoking tool head portion and the mouthpiece, respectively, and which is formed in a hollow cylindrical form, wherein a plurality of filter units filled with the filtering material are slidably inserted into the smoking tool intermediate portion, and can be rearranged so that the filter unit which is the nearest to the smoking tool head portion, among the filter units is taken out and then again inserted into the mouthpiece side end of the smoking tool intermediate portion.
