A slab dab is the inhalation of the vapors produced when someone vaporizes a slab (large amount of concentrated marijuana THC in the form of wax, hash, or etc., pressed into a flat sheet).

This is usually done by placing the slab onto an extremely hot piece of metal that has been heated by a blow torch.
