you can also use the roaches as little filters. some people use a lil piece of rolled up cardboard or somthing (I cannot remember the damn name for those things, but there really is a name), but if im in a joint smoking mood, I'll save the roach, and roll it up in the next joint, and then save that roach and roll it into the next joint ect, for 4-5 joints. by the 5th, the roach is completly soaked in resin (dont hate guys, it isnt tar, its resin. where the hell do you think the resin comes from on pipes?!?!?!?! same concept) and is so sticky you cant touch it without it leaving brown sticky marks on your fingers. then, pop that mofo into a bong/pipe and tear that shit up.
