to the person that said rolling backy helps slow it down thats not true, all it does is help keep it alight and help it burn better, ornageman has started a joint/blunt rolling contest in the recreational forum check it out.

The joint that i submitted was about 6 inches long and that lasted 40 mins i was happy with that, usualy my average joints with king sized slim blue or silva rizlas last about 15-20 mins thats good enough for me, as long as the weed gets into your lungs who cares how long it takes lol.
