This bill amends the existing cannabis testing statute (RCW 69.50.348) to require licensed cannabis producers and processors to submit representative samples of cannabis, usable cannabis, or cannabis-infused products on a testing schedule set by the Liquor and Cannabis Board. Samples must go to independent, third-party testing laboratories that obtain and maintain accreditation from the Washington State Department of Agriculture (DoAg) and follow DoAg laboratory quality standards adopted under chapter 15.150 RCW. Any sample remaining after testing must be destroyed by the laboratory or returned to the licensee. The bill makes the DoAg accreditation the sole basis for initial certification and renewals of laboratory certification for the Board, so long as the lab has not been found to have violated Board requirements. Licensees must submit inspection and testing results required under RCW 69.50.342 to the Board on a Board-developed form. If a representative sample fails to meet applicable Board standards, the entire lot from which the sample was taken must be destroyed unless the Board provides otherwise by rule. DoAg may assess and collect annual fees to support the accreditation and lab quality standards program, may require periodic installment payments, must review and update its fee schedule biennially, and must deposit all fees in the dedicated cannabis account in RCW 69.50.530. DoAg and the interagency coordination team in RCW 15.150.020 are directed to act cooperatively to reduce redundancies. This is a regulatory and procedural change to existing law that imposes testing and accreditation requirements, creates a fee authority to fund accreditation activities, and establishes a lot-destruction consequence for failed tests. The text supplied does not include the specific accreditation criteria, the laboratory quality standards, the Board’s sample submission schedule or form, the amount or method for calculating fees, or the rules the Board may adopt to permit exceptions to lot destruction.

If enacted, licensed cannabis producers and processors will have to send representative samples to independent third‑party labs that the state Department of Agriculture accredits, and those labs must follow state lab quality standards, keep accreditation current, and either destroy or return any leftover samples after testing. Test results and required inspection information must be filed with the Liquor and Cannabis Board on a Board form, and if a sample fails the Board’s standards the whole lot will generally have to be destroyed unless the Board allows an exception by rule. The practical burdens fall mainly on two groups: testing laboratories, which will face upfront and ongoing accreditation work and likely annual fees set and collected by DoAg (including on‑site audits, protocol reviews, and proficiency testing) with those fees deposited to the state’s dedicated cannabis account; and producers/processors, who face costs for testing and a real risk of losing entire product lots if samples fail. Important implementation details are missing here—such as the exact accreditation criteria, the testing schedule, fee amounts, the Board’s submission form, and what exceptions might allow a lot to be spared—so the timing and scale of costs and operational impacts remain uncertain.
