What Is CBC?
Cannabichromene. A minor cannabinoid formed from CBCA, itself derived from the same CBGA precursor.
Measured across 50 lab-tested products from 15 independent laboratories · updated September 3, 2026
Average 0.113% across 50 products that tested positive, from 227 tested in total.
The chemistry
CBC follows the same route as THCA and CBDA: CBGA is converted by an enzyme into CBCA, which decarboxylates to CBC. It appears in small quantities in most full-spectrum material.
Why it matters when you are reading a label
CBC is one of the cannabinoids that distinguishes a genuinely full-spectrum extract from an isolate. Its presence on a COA is evidence the product retains the wider cannabinoid profile.
Products highest in CBC
Ranked by measured CBC content, not by price or popularity. The figure on each card is the one printed on that product’s certificate.
A product can appear high here and low elsewhere — these are single-cannabinoid rankings, not overall potency.
How to read a CBC figure
Percentage is content by weight. Milligrams per serving is the more useful number for edibles and beverages, because it tells you the dose rather than the concentration. Where both appear on a certificate they should reconcile: percentage multiplied by ten gives milligrams per gram.
If a label claims a CBC figure the certificate does not support, trust the certificate.

How much CBC is in a typical hemp product?
Across 50 lab-tested products in this catalogue, CBC ranged from 0.001% to 0.793%, averaging 0.113%. Those results come from 15 independent laboratories. Product form drives most of that spread.
How do I verify the CBC content of a product?
Read the certificate of analysis and match its batch number to the packaging. A certificate that cannot be tied to the batch in your hand does not describe the product you bought.
