CBDA

CANNABIS · GLOSSARY ENTRY

CBDA (Cannabidiolic acid)

The acidic precursor of CBD found in raw cannabis and hemp — converted to CBD by decarboxylation.

Why it matters

CBDA is what raw hemp actually contains in bulk. The conversion to CBD happens with heat, light, and time. Pharmacologically CBDA is a more selective inhibitor of cyclooxygenase-2 than CBD and binds 5-HT1A serotonin receptors with high affinity, which has driven interest in CBDA for nausea and anxiety.

In practice

CBDA-stabilised products (cold-extracted tinctures, raw flower) preserve the acid form. Most conventional CBD oil sold today is mostly decarboxylated and contains little CBDA.

Common confusion

CBDA is not “just CBD before it’s ready.” It has its own pharmacology and is increasingly studied as a stand-alone compound.
