A dab rig is a specialized device used for consuming concentrated forms of cannabis, known as dabs. It typically consists of a water pipe, similar to a bong, but is designed specifically for vaporizing concentrates like wax, shatter, or oil. The rig features a nail or banger, which is heated to a high temperature before the concentrate is applied, allowing it to vaporize and be inhaled. Dab rigs come in various sizes and designs, often made from glass, and may include additional features like percolators for smoother hits. Users often utilize a torch to heat the nail, and accessories like carb caps can enhance the vaporization process.
