Requires certificates of analysis for edible cannabis products to report that THC content does not exceed 10 milligrams per serving, with a tolerance of plus or minus 12 percent until January 1, 2022, and plus or minus 10 percent thereafter.

Clarifies that "final form" for testing purposes means the unpackaged product as it will be consumed, without requiring delivery to the testing laboratory in final retail packaging.

Maintains existing requirements for licensed testing laboratories to test representative samples and issue certificates of analysis reporting chemical profiles and contaminant levels.

Specifies that testing laboratories must follow standard operating procedures to confirm or refute test results falling outside authorized specifications, with bureau authorization required before retesting.

Incorporates provisions from Assembly Bill 1470 if both bills are enacted, with Section 1.5 becoming operative only if this bill is enacted after AB 1470.
