DECARB

What is decarboxylation and what does it mean in relation to hash?   When hash is collected from the plant the majority of the cannabinoids are in the acid form and contain a carboxyl group.  Decarboxylation is a chemical process that converts cannabinoid acids, like THCA, into their activated forms, such as THC. When raw hash is heated, a carboxyl group is removed from the cannabinoid molecule, resulting in a new compound with different properties. For instance, THCA, a solid, transforms into liquid delta-9-THC through decarboxylation. It's crucial to note that this is a chemical conversion and not a phase change.  

A common misconception is to refer to this process as a "phase change," which is incorrect. A phase change involves a physical transformation of a molecule from solid to liquid due to temperature/pressure changes, the chemical make up of the substance that changes phase is not altered. Rosin or hash is a complex mixture of many molecules, it changes from a solid to liquid state as a result of a chemical reaction altering the molecular structure, NOT A PHASE CHANGE!!!

How should I decarboxylate my hash?  The optimal decarboxylation method depends on the desired end product. To preserve flavor and minimize conversion of the many molecules in hash/rosin, isolating cannabinoids before decarboxylation is recommended. This approach allows for targeted heat application to the cannabinoids while protecting other heat-sensitive compounds.  The NIH provides detailed guidelines for decarboxylating pure cannabinoids at various temperatures. It's possible to fully convert THCA into THC in under an hour when temperatures exceed 110 degrees Celsius.
