CBCA
CBC's raw precursor
Cannabinoid
What is CBCA?
CBCA (cannabichromenic acid) is the raw, acidic precursor to CBC, and one of the first compounds produced from CBGA early in the plant's development. It's non-intoxicating in its raw form, and heat converts it to CBC.
Effects
CBCA is less studied than the better-known acids like THCA and CBDA, but it's building its own evidence base. The standout finding: a 2020 study found CBCA was rapidly bactericidal against methicillin-resistant Staphylococcus aureus (MRSA) — faster and more potent than vancomycin, the current antibiotic of choice — without harming mammalian cells. It also showed anticonvulsant activity in a mouse model of Dravet syndrome, and transport studies suggest it's absorbed differently from CBC.

Research note
On a fresh-flower COA, CBCA is usually present in larger amounts than CBC — again, the expected sign of a raw, undecarboxylated sample.
