A joint roller is a device used to roll cannabis into a cylindrical shape for smoking. It consists of two cylindrical rollers, one of which is attached to a base, and a crank or handle that is used to rotate the rollers. The cannabis is placed between the rollers, and the crank is turned to roll the cannabis into a joint.
Joint rollers are used to make the process of rolling a joint easier and more efficient. They can also be used to make joints of a consistent size and shape. Joint rollers are available in a variety of sizes and materials, and some models even have built-in grinders.
