A cigarette holder for extracting tar has first tar extractor with a stick and a first disc with apertures. A second tar extractor has a cylinder fitted to the stick and a second disc provided on one end of the cylinder and fitted in a flue of transparent resin. Smoke collision portions in the flue face the apertures. Smoke is compressed and accelerated when it passes through the apertures and expands again to collide with the smoke collision portions. It then collides with the second disc. Then the smoke is compressed and accelerated when it passes through the outer circumference of the second disc and the flue. Tar is extracted at each stage and the smoke is cooled by the second tar extractor before it reaches a mouth piece of the holder.
