Regulatory Source
Testing licences in California are issued by the California Department of Cannabis Control (CA DCC) and generally require ISO/IEC 17025 accreditation alongside the cannabis licence. Because the class is so small, this page is close to a complete census of the California market rather than a sample of it.
Our crawler runs against the California Department of Cannabis Control weekly, capturing new licensees, closures, and status changes automatically. See the full market picture — counts by city and contact coverage — in the California testing lab statistics.
