BHO

Butane Hash Oil, a cannabis concentrate extracted using butane as a solvent, producing wax, shatter, or oil.

BHO stands for Butane Hash Oil, a category of cannabis concentrates extracted using butane as the primary solvent. BHO extraction can produce various end products including shatter, wax, budder, crumble, and live resin, depending on the post-extraction processing techniques applied.

The Extraction Process

In a closed-loop BHO extraction, liquid butane is passed through a column packed with cannabis material. The butane strips cannabinoids, terpenes, and other desirable compounds from the plant. The butane-extract mixture is then collected and the butane is purged through a combination of heat and vacuum pressure. Professional extractors use commercial-grade equipment with recovery systems that recapture and recycle the butane, making the process safer and more efficient.

Safety and Quality

Open-blast BHO extraction (not using a closed-loop system) is extremely dangerous due to the explosive nature of butane and has caused numerous fires and explosions. This is why BHO production is illegal outside of licensed facilities in regulated markets. Consumer safety relies on proper purging to remove residual butane below safe thresholds, verified by third-party lab testing. When properly produced and tested, BHO concentrates are considered safe for consumption. Always purchase from licensed sources and check the certificate of analysis for residual solvent results.
