Abstract: Devices and methods for pre-rolled smoking tubes are described herein. The devices include a tube configured to roll a smoking tube. The tube includes a distal end having a distal opening, a proximal end spaced from the distal end along a central axis, the proximal end having at least one or a plurality of customizable proximal openings that regulate airflow in the tube, and a lumen that extends from the distal opening to the at least one proximal opening along the central axis. This configuration allows the creation of differing airflow patterns in the tube, reduced waste of desired materials during the manufacturing of filled smoking tubes, and reduced charred materials entering a user's oral cavity. The device may also be used, in whole or in part, as a mandrel during the manufacturing of pre-rolled tubes via an automated, semi-automated, or manual processes.
