IndustryDevelopments | International & State California The state marijuana market is borrowing a page from California's world-famous wine industry. Gov. Gavin Newsom signed a bill into law establishing that any cannabis product claiming an " appellation of origin " from a California region must have been grown in the soil and with the sun from that region-in other words, without artificial light or shelter. The designation of origin will be especially useful in the event that federal cannabis legalization allows interstate commerce. Certain regions in California-including Humboldt, Mendocino, Nevada and Trinity counties as well as Big Sur-have decades-long histories and well-established reputations for producing high-quality " sun-grown " cannabis. Colorado State regulators adopted new rules for testing cannabis vapor to ensure consumer safety for vape products; the move also adds a cost to marijuana companies. The Colorado Marijuana Enforcement Division released new rules on Oct. 9 that require companies to test " emissions " from vape products-essentially, examining the aerosol the consumer is inhaling that's produced from vaping cannabis oil. Until now, only the cannabis oil has been analyzed in laboratories. Another rule requires manufacturers to label cannabis vape cartridges in Colorado with an expiration date. The new regulations will take effect Jan. 1, 2022.
