Cal. Code Regs. Tit. 4, § 15724 - Cannabinoid Testing

(a) The licensed laboratory shall analyze at minimum 0.5 grams of the representative sample of cannabis and cannabis products to determine the cannabinoid profile such as THC; THCA; CBD; CBDA; CBG; and CBN.

(b) The licensed laboratory shall establish a limit of quantitation (LOQ) of 1.0 mg/g or lower for all cannabinoids analyzed and reported.

(c) The licensed laboratory shall report the result of the cannabinoid testing on the COA, including, at minimum:

(1) A percentage for THC, THCA, CBD, and CBDA;

(A) When the licensed laboratory reports the result of the cannabinoid testing for harvest batch representative samples on the COA in dry-weight percent, they shall use the following equation:

Dry-weight percent cannabinoid = wet-weight percent cannabinoid / (1- percent moisture / 100)

(2) A percentage for Total THC and Total CBD, if applicable;

(3) Milligrams per gram (mg/g) if by dry-weight or milligrams per milliliter (mg/mL) if by volume for THC, THCA, CBD, and CBDA.

(4) Milligrams per gram (mg/g) if by dry-weight or milligrams per milliliter (mg/mL) if by volume for Total THC and Total CBD, if applicable;

(A) The licensed laboratory shall calculate the total cannabinoid concentration as follows:

(i) For concentration expressed in weight:

Total cannabinoid concentration (mg/g) = (cannabinoid acid form concentration (mg/g) x 0.877) + cannabinoid concentration (mg/g)

(ii) For concentration expressed in volume:

Total cannabinoid concentration (mg/mL) = (cannabinoid acid form concentration (mg/mL) x 0.877) + cannabinoid concentration (mg/mL)

(5) Milligrams per package for THC and CBD;

(6) Milligrams per package for Total THC and Total CBD, if applicable;

(7) Milligrams per serving for THC and CBD, if any;

(8) Milligrams per serving for Total THC and Total CBD, if any and if applicable; and

(9) The licensed laboratory shall report the results of all other cannabinoids analyzed on the COA both as a percentage and in either milligrams per gram (mg/g) if by weight or milligrams per milliliter (mg/mL) if by volume.

(d) The sample shall be deemed to have passed the cannabinoid testing if the amount of THC does not exceed the limits established in section 17304.

(e) The licensed laboratory shall report the test results and indicate an overall "pass" or "fail" for the cannabinoid testing on the COA.

(f) Any cannabinoids found to be less than the LOQ shall be reported on the COA as " <1 mg/g" if by dry-weight or " <1 mg/mL" if by volume.

(g) If the sample fails cannabinoid testing, the batch from which the sample was collected fails cannabinoid testing and shall not be released for retail sale.

(h) For purposes of this division, any one cannabinoid, Total THC, and/or Total CBD claimed to be present on a label shall not be considered inaccurate if the difference in percentage on the certificate of analysis is plus or minus 10.0%.
