Butane Hash Oil, or BHO, is one of the most commonly seen extraction products in the cannabis market due to its versatility and high THC content. BHO is a type of cannabis concentrate that is made by extracting THC and terpenes from cannabis flowers or trim by using butane, pressure and heat. It is often thick and amber-colored, coming in a variety of textures from oily to glass-like. During extraction, cannabinoids and terpenes get concentrated in the oil, making the end product extremely potent. Most BHO products have THC contents of 50-90%.

Butane is a non-polar chemical solvent which liquefies easily and when pushed through cannabis material, it will quickly dissolve the plant’s trichomes and cannabinoids. The resulting solution is a mixture of cannabinoids dissolved in butane. ISO butane blends are typically a mixture of butane and propane and offer a similar result, but is often believed to extract a more complete terpene profile. Depending on the type, BHO can be used in edibles, vape pens, topical creams, and tinctures, as well as smoked.

Once the cannabis mixture is properly purged to remove all the butane, you are left with a waxy to glass-like amber-colored substance. It is this purging process which determines the product’s final texture. A closed-loop extraction system is recommended, which features a well-sealed tank and attached tube where the blasting is confined. Open-blasting can be achieved with just a few materials, but its highly-flammable and explosive nature requires utmost care and professionalism.
