Hybrid strain wax in crumble form. Crumble, sometimes called crumble wax or honeycomb wax, is a cannabis extract identified by its malleable texture that falls apart, or “crumbles,” when handled. Unlike other weed concentrates, such as shatter, wax, budder, resin, or cannabis oils, crumble is quite versatile. Not limited to dabbing only, you can easily add it to joints, blunts, or spliffs, or sprinkle crumble over the top of marijuana buds in a bowl or pipe.
