Butane is the principle solvent used to extract cannabis oil from the plant.

Extracts are often created using a process that involves butane, hence the term “butane hash oil” (BHO).

Normal butane can be used for gasoline blending, as a fuel gas, fragrance extraction solvent, either alone or in a mixture with propane, and as a feedstock for the manufacture of ethylene and butadiene, a key ingredient of synthetic rubber.
