Dept. of Cannabis Seeks Public Input on Lab Testing Rules

The California Department of Cannabis Control (DCC) is seeking public comment on proposed standardized testing methods that all laboratories would have to follow when evaluating THC levels. The aim is to stop the common practice of “laboratory shopping” in which marijuana businesses seek out labs that will slap a higher THC concentration level on their products.

“One of the challenges we face in regulating an industry that is not federally recognized, is the lack of standardized, and validated methods for testing,” said DCC Director Nicole Elliott. “Individual, licensed laboratories use different methods which may produce inconsistent results and inaccurate data on cannabis cannabinoid content. DCC is working to change that so there is greater integrity in the market, accurate information for consumers, and confidence among stakeholders.”

DCC is seeking the public’s input through August 2, 2022. The proposed regulations can be viewed here.

Public comments may be submitted by mail to DCC Legal Affairs Division, 2920 Kilgore Road, Rancho Cordova, CA 95670; by email at; or in person at the public comment hearing on Aug. 1, 2022, from 9 a.m. to 12 p.m.
