You've mastered rolling your own cigarettes and ready for life's next great challenge? Try doing like the person in this video and rolling a cigarette with one hand. He makes it a look a whole lot easier than it really is but get your rolling paper and tobacco out and start practicing.
A few clips of me rolling with 1 hand and filming with the other. There are many different techniques out there but this is mine. It looks hard but isn't really. I picked it up in a few weeks and I'm sure you can too.
