Hash holes are a type of infused cannabis pre-roll that features a “worm” or streak of concentrate, typically solventless live rosin, rolled into the center of the cannabis flower. As the joint burns, the concentrate vaporizes faster than the surrounding flower, creating a distinctive “hole” in the middle, which is how they got their name, though they are also known as “donut holes” or “wormholes”. This design significantly enhances the potency and flavor of the cannabis experience compared to traditional joints.
