In my opinion, every toker should know how to roll!! Its easy to pack a bowl, but make a joint? Thats fuckin art. Adjust the mix of tob/weed the way you like it (smooth or harsh), you make a long roach or a short one, a tight one or a loose one, you make a fat joint or a slim joint, a tulip, a cone, you name it! theres just too many things to do in such a small item (not always too small )
