Portland stores that sell CBD edibles, tinctures and beverages will have to pull those products from their shelves by Dec. 11 under a new federal law.

The ban covers any "hemp-derived cannabinoid product" with more than 0.4 milligrams of total THC per container. That threshold wipes out roughly 95% of hemp-derived cannabinoid products sold in the United States, according to Insurance Journal. Gas stations, convenience stores and supermarkets across Oregon will all be affected.

The law was tucked into a government funding bill during the late 2025 government shutdown. Sen. Mitch McConnell, R-Ky., added the amendment, repealing the 2018 farm bill provision he once championed that legalized hemp cultivation at 0.3% THC or lower by dry weight. That 2018 law had created an unintended loophole allowing manufacturers to convert legal hemp into synthetic cannabinoids like delta-8 and HHC.

Congress pushed the ban's effective date from Nov. 12 to Dec. 11 after President Trump signed a delay measure into law. The Senate passed it 90-6 on Aug. 8 and the House approved it 370-48 on Sept. 1, CSP Daily News reported. Synthetic cannabinoids still face the earlier Nov. 12 ban.

The fallout is visible across the Willamette Valley. Oregon CBD Company, a retailer in Albany, plans to close its storefront by the end of September, the Oregon Capital Chronicle first reported. A "for rent" sign hangs outside the building. Shelves that once held pet tinctures and topicals sit empty.

Store manager Leslie Frost told the Chronicle the biggest loss will be customers who bought CBD for their pets. Frost said she took 1,200 milligrams of ibuprofen a day before turning to CBD herself.

Seth Crawford, co-owner of Oregon CBD Seeds in Independence, supplies 75% of the hemp seed grown in the country. He told the Chronicle the new law will devastate his business, which was recovering from a post-pandemic sales decline.

"The law essentially ends the hemp industry," Crawford said.

Farmers can still grow hemp. But Crawford said he expects far fewer seed buyers because processors won't be able to make products under the strict new limits. His fallback plan is selling seeds to home growers.

Oregon's U.S. Sens. Ron Wyden and Jeff Merkley reintroduced the Cannabinoid Safety and Regulation Act in December 2025. The bill would regulate hemp products through the FDA, set a minimum purchase age of 21 and require safety testing. It has not advanced since its introduction.

Synthetic cannabinoids face the Nov. 12 ban. Naturally derived hemp products follow one month later, on Dec. 11.
