The tobacco substitute having a smoking-like effect of the present invention comprises: a filter part touching lips of a user, and having a filter therein and a casing part provided at the side of the filter part and receiving an exchangeable tobacco substitute core. The casing part comprises a suction tube, a tobacco substitute core-coupling element, and a tobacco substitute core extrusion port. The suction tube is provided inside the casing part such that one end of the suction tube is in contact with the filter part, and the suction tube is a passage that is formed to suck the tobacco substitute core. The tobacco substitute core-coupling element is provided at the other end of the suction tube to fix the tobacco substitute core. The tobacco substitute core extrusion port is provided inside the casing part and formed in an L shape. An upper portion of the tobacco substitute core extrusion port forms a protrusion protruding above the casing part, and a lower portion of the tobacco substitute core extrusion port is positioned inside the suction tube, and thus, as the protrusion moves to the left or right side, the tobacco substitute core fixed to the tobacco substitute core-coupling element is separated, thereby facilitating the exchange of the core substitute core.COPYRIGHT KIPO 2016본 발명은 담배를 피우는 듯한 효과를 갖는 담배대용품에 관한 것으로, 보다 상세하게는 내부를 해로운 담배 성분 대신 각종 식물(침엽수, 활엽수,
