the joint roller is what saved me at school this year. i taught myself how to use it when the kid who owned it wasn't around to do it for me, and it is easy peasy lemon squeezy. we never put a roach in there, and the best part was that it always looked like a cigarette, so we didn't have to worry about people seeing a makeshift joint and all that shit. The roller we used made different sized joints depending on how much weed we used, so not all of them were the same and just packed differently. Brilliant.
