California Program Information
California has selected Metrc as the state’s track-and-trace system used to track commercial cannabis activity and movement across the distribution chain ("seed-to-sale"). This site is intended to give annual and provisional licensees information that will help them use Metrc to remain in compliance with California’s tracking and reporting requirements.
For information on California’s programs – including regulatory requirements – visit the following websites:
Bureau of Cannabis Control - a bureau within the California Department of Consumer Affairs, BCC is responsible for licensing retailers, distributors, testing laboratories and microbusinesses.
