The Bureau of Cannabis Control (BCC) is responsible for regulating commercial cannabis licenses for retailers, distributors, microbusinesses, testing laboratories, and temporary cannabis events. As the proposed permanent regulations are being reviewed by the Office of Administrative Law (OAL), the BCC released a new schedule of required testing for cannabis operators. Read on to learn more about what you need to know about cannabis testing laboratories and cannabis testing requirements that will be phased in on December 31, 2018.

A testing laboratory, facility, or entity in the state that offers or performs tests of cannabis goods. Testing laboratories must obtain and maintain ISO/IEC 17025 accreditation. Testing laboratories may be issued a provisional license allowing them to operate while they obtain ISO/IEC 17025 accreditation, provided they meet all other licensure requirements (BCC, 2018).

All cannabis harvested on or after January 1, 2018, and all cannabis products manufactured on or after January 1, 2018, must be tested according to Title 16 of the California Code of Regulations, Section 5715.
