§ 5716. Homogeneity Testing of Edible Cannabis Products (a) The laboratory shall analyze a sample of edible cannabis product that contains more than one serving per unit to determine whether the edible cannabis product is of homogeneous THC content. (b) The laboratory shall perform homogeneity testing when the first batch of edible cannabis product is tested before entering the retail market. Once the initial batch of the product passes homogeneity testing, and provided that the process for manufacturing and the composition of the edible cannabis product remains the same, a batch of edible cannabis product shall be tested for homogeneity every 6 months thereafter. (c) A sample of edible cannabis product shall be deemed to have passed homogeneity testing if the relative standard deviation of THC concentration between the samples collected does not exceed plus or minus 10%. (d) If a sample fails homogeneity testing, or the laboratory fails to perform homogeneity testing as required by this section, the batch from which the sample was collected fails homogeneity testing and may not be released for retail sale. (e) If a sample passes homogeneity testing, the laboratory shall perform all other analyses required under this chapter. Authority: Section 26013, Business and Professions Code.
