There are a lot of different ways to make extracts, here are some of the more popular ways. Each way has its advantages and disadvantages. Everyone is trying to hit the perfect point where they get the best taste from terpenes with the highest amount of cannabinoids.
BHO: Butane Honey Oil, or BHO, is the essential oil from the cannabis plant, extracted using Butane as a solvent. It can be extracted from fresh material or from cured material
PHO: Propane Hash Oil, or PHO, is the essential oil from the cannabis plant, extracted using Propane as a solvent. It can be extracted from fresh material or from cured material
Live Resin: BHO or PHO extract taken from fresh material that has been frozen immediately after harvesting the plant. This process preserves the terpenes and cannabinoids that could be lost using dried and cured material
CO2 Oil: CO2 oil, a concentrate 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.
Distillate: Distillates use an extraction process called “short path distillation” that separates and refines molecules and contaminants to create a clean, almost clear concentrate. Other extraction methods don’t produce nearly the same purity level or variety of uses as this technique, making it highly regarded as a “top-shelf” concentrate.
Decarbed Oil: is a chemical reaction that removes a carboxyl group and releases carbon dioxide (CO2). Usually, decarboxylation refers to a reaction of carboxylic acids, removing a carbon atom from a carbon chain. In living cannabis plants, the cannabinoids are synthesized in an acidic form. This form has little effect on humans and must be heated to lose a carbon dioxide molecule to become active.
