Rolling a joint with a dollar follows something of the same mechanics of a joint-rolling machine. You take a dollar and fold one end a few inches over towards the center. Turn the dollar counter clockwise till it’s pointing upwards, and use the fold you made as a basin. Take some cannabis and place it in the basin and roll it in the joint to pack it down. Then take a paper and place it in the basin with the glue facing you, like you did with the rolling machine, lick the glue, and roll it in the paper with a few revolutions. Remove the joint and you’re ready to go.
