indeed. i stuffed mine with about 10 haha. but not only does the smoke come out smelling FRESH, it seems to entirely DISSIPATE it too. very effective on the whole -- take a fatass snapper then blow it through the tube, just make sure to clear your bong all the way or smokell still be coming out. then expose something smelly - anything - to the air to cover up any additional odours. :stoned:
