Cannabis concentrates are any cannabis product procured through an extraction process. Solvents (e.g., butane, CO2, ethanol) strip compounds from the cannabis plant, leaving behind a product with cannabinoids packed in every drop. Some types of extracts test as high as 80% in THC, while others rich in non-psychoactive compounds like CBD deliver an altogether “high-less” experience.
Here is a list of common cannabis concentrates:
Hash is made by compression of the plant’s resin. The powdery kief that coats your cannabis flowers can be collected and pressed together to form hash, or solvents like ice water or ethanol may be used to more effectively strip the plant of their cannabinoid-loaded crystals. Though not as potent as BHO and other cannabis concentrates, hash remains a staple of cannabis culture around the world.
BHO, or butane hash oil, is an extremely potent concentrate popularly consumed for dabbing and other vaporization methods. Cannabinoids are drawn out of the plant through butane extraction, which leaves behind a wax that will either maintain its sticky consistency or harden up, resulting in a crumbly “honeycomb” or a glasslike “shatter.”
This concentrate is made possible by expensive botanical extractors that use pressure and carbon dioxide to separate plant material. This method, called supercritical fluid extraction, is one of the most effective ways of reducing cannabis to its essential compounds.
By soaking the hemp in pure naphtha or isopropyl alcohol, the therapeutic compounds are drawn out of the plant, leaving behind a tar-like liquid after the solvent fully evaporates.
Up until its prohibition in 1937, tinctures were the most common form of cannabis medicine in the United States. A tincture is a liquid concentrate procured through alcohol extraction, which pulls out many of the plant’s beneficial cannabinoids.
