The rationale for the is consumer safety – which seems like a legitimate concern given that recreational use cannabis producers were previously not required to test for pesticides at all. Indeed, one cannabis testing laboratory released a white paper earlier this year claiming that cannabis pesticide contamination is a serious issue in Washington, especially for concentrates that, when tested on an “off the shelf” basis in 2018, had pesticide failure rate as high as 40%.
While the LCB’s goals may be sincere, they will have some pretty significant effects on the industry. In this post, we outline what we think are the two biggest ones:
Cannabis pesticide testing is now required for cannabis flower and all intermediate cannabis products that are used in the creation of end products like cannabis extract and concentrates; and Lots, batches, and (“theoretically” according to the LCB) harvests that fail pesticide sample testing may no longer be remediated and those that fail must be destroyed.
