a roach, atleast mine are very small.. they're about maybe 1/4 inch long (the width of a cigarette) lol just so you know... also, to help it burn a little bit easier, if you rolled a joint with pure weed... put a pinch of tobacco in with the weed before you roll it.. like 1/10 the ammount of weed... it helps it burn more evenly.. and you can't taste the tobacco or anything so it's not like that makes it taste disgusting..
