About the Manufactured Cannabis Safety Branch
The California Department of Public Health’s Manufactured Cannabis Safety Branch (MCSB) is one of three state cannabis authorities charged with licensing and regulating commercial cannabis activity in California. MCSB regulates all commercial cannabis manufacturing in the state and strives to protect public health by ensuring commercial cannabis manufacturers operate safe, sanitary workplaces and produce products that are free of contaminants, meet product guidelines and are properly packaged and labeled.
The state cannabis authorities adopted emergency regulations for initial implementation of the provisions of Medicinal and Adult-Use Cannabis Regulation and Safety Act (MAUCRSA)and are now using the regular rulemaking process to adopt permanent regulations.
