Rig

A unique pipe with a nail or skillet used to consume concentrates like wax or shatter. 'Dabbing' involves heating the nail on the rig to a specific temperature with a handheld torch, which evaporates a dab of concentrate when placed on the heated device. This form of consumption is different than smoking from a bowl or pipe with flower and produces a purer inhalation. Dabbing with a rig is quickly gaining popularity in the cannabis industry.

Roach

A roach is the end of a joint and is often too small to be smoked for fear of burning ones fingers. As a result, a roach is typically smoked with a roach clip or saved with other roaches to be used in another, stronger joint or added to a bowl.

Ruderalis

Ruderalis is one of the three species of cannabis besides Indica and Sativa. Originally, Ruderalis was considered as a wild breed of cannabis that can survive human activities and even adapt to extremely harsh conditions. The plant has small leaves and a short stature that only grows to about 2 feet (or .6 meter) tall hence the name dwarf cannabis. Ruderalis most notable characteristic is its ability to begin flowering based on changes in the plant instead of its environment (auto-flowering). The plant has low Tetrahydrocannabinol (or THC) concentrations making it less favorable for recreational or medical use. It’s native origin is traced back in Russia.
