. Earlier this year, the chain announced a plant-based alternative to its signature burger in partnership with Beyond Meat.

“I was sitting down with our head chef Owen Klein, and we

were talking about trends,” Trevino said. After the Beyond Meat launch, they came up with a wish list that included a CBD product. “We looked at ourselves and said, ‘You know what, let’s try.'”

CBD is an attractive new ingredient for companies, but they have to act carefully because regulation around use of the ingredient is ill-defined. Hemp was legalized nationally last year as part of the Farm Bill, but the Food & Drug Administration still hasn’t decided how to regulate CBD products. In a March  with Brookings Institution, former FDA commissioner Scott Gottlieb said it could take several years before the agency fully legalizes CBD for use in food products and dietary supplements.

Starting small, in a market where cannabis regulation is “really strong,” will allow Carl’s Jr. to figure out how to move forward. Testing CBD could give the company an edge over competitors, because most of its locations are in Western states, where recreational cannabis is legal.

Because Carl’s Jr. decided to test in just one location on one day, it was able to bring a product to customers very quickly. The chain partnered with Bluebird Botanicals, a Colorado-based company that sells CBD oil and capsules, for the test.
