A Carton, or " cut "in Quebec is a small piece of cardboard rolled into a cylinder of variable length and placed at the end of a rolling sheet when making a joint, however, a Carton can just as easily be used for a normal rolled cigarette. It allows a better hold during its consumption, as well as to avoid leaving unburned cannabis at the end of the joint, and to prevent ashes from reaching the smoker's mouth.
