SB 378 Online marketplaces: illicit cannabis: reporting and liability.
(1) Existing law, the Control, Regulate and Tax Adult Use of Marijuana Act (AUMA), an initiative measure, authorizes a person who obtains a state license under AUMA and any applicable local ordinances to engage in commercial adult-use cannabis activity pursuant to that license, if conducted as prescribed. Existing law, the Medicinal and Adult-Use Cannabis Regulation and Safety Act (MAUCRSA), among other things, consolidates the licensure and regulation of commercial medicinal and adult-use cannabis activities, and requires the Department of Cannabis Control to administer its provisions.
Existing law, until January 1, 2028, requires a social media platform to create and post a policy statement regarding the use of the social media platform to illegally distribute controlled substances, including a link to the social media platform’s reporting mechanism for illegal or harmful content or behavior on the social media platform, if one exists, and a general description of its policies and procedures for responding to law enforcement inquiries.
This bill would require an online cannabis marketplace, as defined, to address in its terms of service whether it permits Californians to view the advertisements and business information of unlicensed sellers of cannabis or cannabis products on its marketplace and whether the marketplace verifies the licenses of sellers of cannabis or cannabis products whose advertisements and business information are viewable on its marketplace, as specified. The bill would require an online cannabis marketplace that does not verify those licenses to display a graphic that warns the consumer about various risks associated with cannabis from unlicensed sellers before the consumer can view or engage with the marketplace.
This bill would require an online cannabis marketplace to establish a prominent mechanism within its internet-based service that allows an individual to report to the online cannabis marketplace the display, storing, or hosting on the marketplace of advertisements from, or business information about, an unlicensed seller of cannabis or cannabis products. The bill would require the mechanism to provide the individual who submits a report with written confirmation of receipt of the report, periodic updates, and final written determination, as specified.
This bill would impose certain penalties and relief, and would authorize various parties to bring civil enforcement actions, depending on the violation of these provisions, as specified.
(2) The Sherman Food, Drug, and Cosmetic Law regulates the packaging, labeling, and advertising of food, beverages, and cosmetics and authorizes the State Department of Public Health to adopt regulations for the enforcement of that law, as specified. That law imposes various requirements specific to the manufacture and sale of industrial hemp products that are food or beverages, including a requirement for a certificate of analysis from an independent testing laboratory that confirms that the THC concentration does not exceed a specified amount. Existing emergency regulations require that industrial hemp food, food additives, beverages, and dietary supplements intended for human consumption have no detectable THC per serving.
This bill would require an online hemp marketplace, as defined, to establish a prominent mechanism within its internet-based service that allows an individual to report to the online hemp marketplace an advertisement for an intoxicating hemp product on the marketplace, as specified. The bill would require the mechanism to provide the individual who submits a report with written confirmation of receipt of the report, periodic updates, and final written determination, as specified. The bill would authorize certain parties to bring a civil action, including, among others, a licensed seller of cannabis or cannabis products and the Attorney General. The bill would impose specified penalties and relief for violations of these provisions.
(3) Existing law imposes strict liability upon persons who place a defective product on the market, including retailers engaged in the business of distributing goods to the public, for injuries caused by the product.
The bill would impose strict liability on an online marketplace that facilitated the connection between a consumer and an unlicensed seller of cannabis or a cannabis product for damages caused to the consumer by the cannabis or cannabis product, as provided. The bill would also impose strict liability on an online marketplace that facilitated the connection between a consumer and a seller of an intoxicating hemp product for damages caused to the consumer by the intoxicating hemp product, as provided. The bill would increase the amount that a prevailing plaintiff may recover depending on what the online market knew or should have known at the time it facilitated the connection and whether the harm was suffered by a child, as described.
(4) This bill would state that its provisions are severable.
