Legislative Update: Assembly Bill 1529 – Modification to Vape Cartridge Labeling Requirements

Assembly Bill (AB) 1529 was recently signed into law and modifies the labeling requirements for cannabis vaping products. The bill is effective immediately and does not require regulatory changes to be effective.

All vape cartridges and integrated vaping devices sold within California must be directly labeled with the Universal Symbol for cannabis. AB 1529 specifies the symbol may be engraved, affixed with a sticker or printed directly onto the cartridge; may be printed in either black or white; and must be at least one quarter inch by one quarter inch in size.

The CDPH Manufactured Cannabis Safety Branch previously established labeling requirements for the innermost container of manufactured cannabis products, including the requirement that vape cartridges be labeled with the Universal Symbol (§40403). AB 1529 adds clarity to those requirements and modifies the size and color requirements to ease burdens associated with its implementation.

This labeling requirement was established to ensure consumers are informed that the vaping product contains cannabis, even after the outer packaging is discarded. The requirement also distinguishes legal market cannabis product from cannabis vaping products that are sold by unlicensed sellers.

The California Department of Public Health’s Manufactured Cannabis Safety Branch (MCSB) is one of three state licensing authorities charged with oversight of commercial cannabis activity in California. MCSB is responsible for licensing and regulating cannabis manufacturers and for establishing statewide standards for packaging and labeling of cannabis and cannabis products.

MCSB strives 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.
