Manufactured Cannabis Safety Branch


The California Department of Public Health’s Manufactured Cannabis Safety Branch (MCSB) is one of three state licensing authorities charged with licensing and regulating commercial cannabis activity in California. MCSB is responsible for regulation of all commercial cannabis manufacturing in California.

We strive to protect public health and safety by ensuring commercial cannabis manufacturers operate safe, sanitary workplaces and follow good manufacturing practices to produce products that are free of contaminants, meet product guidelines and are properly packaged and labeled.
