Essentially a form of Cannabis joints, prerolls are Cannabis cigars prepared by dispensaries or smoke shops for their customers. The most common ingredients are a wrap or paper, ground Cannabis, and a filter or crutch securely wedged at the product’s base. Some are offered individually in tubes, while others are sold in multi-packs. Preroll sizing can range from the length of a pinky finger to that of a smartphone. The sizes all depend on the packing.
