dabrigs's definitions
An apparatus, usually of glass, designed for vaporizing medical marijuana concentrates. Most rigs are designed to be used in conjunction with a titanium nail, glass dome and dabber, though domeless nails are also commonly implemented. Rigs or 'oil rigs' can be differentiated from standard bongs and pipes by the ground glass joint they exhibit. Oil rigs have male joints (referred to as 'direct inject' within the industry) whereas other scientific glass bongs designed for bud have a female ground joint.
