The public has until 5 p.m. Sunday to comment on proposed rules that would reduce the amount of testing required for marijuana extracts and concentrates headed to the market.

Among the proposals: Instead of requiring that every batch of marijuana extract and concentrate be screened for pesticide contamination, the products would be randomly tested annually. Marijuana used to make those products would be screened for pesticides.

The state also has proposed new rules for marijuana flower headed to the market. Current rules require about 33 percent of all batches of marijuana flower for the recreational system be tested for pesticides. The change would give authority to the Oregon Liquor Control Commission to require less testing. Under the proposal, at least 20 percent of marijuana flower would undergo pesticide testing. (In the medical marijuana system, 100 percent of medical flower batches still would undergo pesticide testing.)

The industry is split over the proposals. Some argue they represent a setback for public health and will let tainted product slip into the market. Others support the proposals, citing the cost and lack of reliability of current testing.

An agency spokesman on Friday said officials will review public comments before deciding whether to move ahead. If adopted, the new rules would go into place June 1.

The public may email comments to: publichealth.rules@state.or.us.
