CBC, cannabichromene, is the neutral form of CBCA, one of the three main products the plant can make from CBGA. It is a minor cannabinoid in nearly all modern drug-type and hemp-type material, though some reports find relatively higher CBCA in young plants and in certain lines. Light exposure can slowly convert CBC into CBL during storage.
In practice
Many potency panels report CBC or CBCA alongside the main cannabinoids. A reading of 0.1-0.5% w/w is typical for flower. It counts toward total cannabinoids but rarely changes a plant's classification. GenetixBay makes no claims about CBC's effects; human evidence is thin.
Don't confuse with
- CBCA: the acid form the plant makes.
- CBN: a THC oxidation product with a similar abbreviation.
- CBL: a light-induced breakdown product of CBC.
CBCA (cannabichromenic acid) is the acid cannabinoid that CBCA synthase makes from CBGA; it decarboxylates to CBC and is usually a minor component of the profile.CBGA (cannabigerolic acid) is the precursor cannabinoid that the plant converts into THCA, CBDA or CBCA, formed by joining olivetolic acid to geranyl pyrophosphate.A cannabinoid is any compound that binds the body's cannabinoid receptors or shares the typical cannabis terpenophenolic structure; the plant-made ones are phytocannabinoids such as THCA and CBDA.CBL (cannabicyclol) is a minor cannabinoid formed when CBC is exposed to light; it is a degradation product rather than something the plant makes by enzyme.Total cannabinoids is the sum of all cannabinoids a lab measured in a sample, usually reported in % w/w, with acid forms either summed raw or decarboxylation-adjusted.CBN (cannabinol) is a cannabinoid formed mainly when THC or THCA oxidises after harvest, so high CBN readings usually signal age, heat, light or air exposure, not plant ripeness.THC (Δ9-tetrahydrocannabinol) is the neutral, decarboxylated cannabinoid mainly responsible for cannabis's reported intoxicating effects; the living plant makes it almost entirely as THCA.Decarboxylation is the loss of a carboxyl group as CO2 that turns acid cannabinoids such as THCA and CBDA into neutral THC and CBD, quickly with heat, slowly with time.
