The California Department of Public Health's Manufactured Cannabis Safety Branch (MCSB) is responsible for licensing all commercial cannabis manufacturers within the state of California.

California state law requires that all commercial cannabis businesses hold a state license in order to operate in the commercial market. As a licensee, you must follow all applicable state law and local ordinances.
