As of August 30th, 2017, all cannabis product batches must be tested for pesticides according to the Oregon Health Authority guidelines. This comes after temporary regulations on testing expired and in the face of findings that far more pesticides were found in products that were making their way to consumers than was considered safe.

The previous temporary regulations had reduced testing requirements to only required one-third of batches of usable marijuana within every harvest lot in October of 2016, primarily due to insufficient lab capacity.

According to the Oregon Liquor Control Commission, “Since that time, significant changes have occurred that have increased the lab testing capacity to ensure a steady flow of product through the supply chain. Last October, fewer than five labs were accredited to test for pesticides; today there are nearly ten such labs. Additionally, the Oregon Health Authority’s most recent testing rules increased by 50% the amount of usable marijuana that can be tested together in a batch.”

When the state proposed changes to the testing protocol, the public overwhelmingly opposed changes to original regulations out of a desire to protect the public from potentially dangerous contaminants.

“The Commission recently examined the issue and determined that limited lab capacity issues that existed in October of 2016 have been mitigated,” the OLCC said in their statement. “Lab testing capacity has increased to ensure a steady flow of product through the supply chain. Last October, fewer than five labs were accredited to test for pesticides; today there is more than double the capacity. Additionally, the Oregon Health Authority’s most recent testing rules increased by 50% the amount of usable marijuana that can be tested together in a batch.”

Regulations extend to batches of untested product that were collected for testing prior to August 30th, and all new regulations must be adhered to. You can learn more about other changes and regulations on the Oregon Health Authority’s page on marijuana.
