Butane hash oil (BHO) refers to any number of oleoresin cannabis extracts produced using pressurized butane as the primary solvent to perform chemical extraction. Skilled extractors carefully run finely ground plant material like flower and trim through enclosed systems using pressurized butane to selectively dissolve and strip away the most desirable compounds like THC, CBD, terpenes, flavonoids and waxes from the raw cannabis. By utilizing different post-processing techniques, BHO can take on many distinct consistencies inclduing clear and glassy shatter, moist and viscous sap or budder, crumbly wax, and crystalline sauce. BHO is consumed almost exclusively via dabbing/vaporizing on a hot surface rather than smoking, although it can be added in small amounts on top of dried flower in bowls or joints. When manufactured professionally using top quality starting material, BHO can test over 90% THC by weight for dramatically elevated potency compared to unextracted dried flower. However, amateur or DIY butane cannabis extraction is extremely dangerous due to the highly volatile flammability of butane gas, and attempting makeshift home BHO runs has resulted in numerous fires, explosions and injuries due to lack of proper ventilation, safety protocol and equipment.
