CBD oil has been billed as a miracle cure for all kinds of ailments.* But now it's making its way into fast food. Carl's Jr—better known as Hardee's in Wisconsin—has not been one to shy away from experimenting with their menu. The chain announced this week that it will sell the Rocky Mountain High: CheeseBurger Delight burger at one location in Denver, Colorado for just one day (April 20, of course). The burger features a sauce infused with CBD, or cannabidiol, a non-psychoactive hemp derivative.

The CheeseBurger Delight consists of two beef patties, topped with pickled jalapenos, pepper jack cheese, fries, and CBD-infused "Santa Fe Sauce."

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 could bring a product to customers very quickly. The chain collaborated with Bluebird Botanicals, a Colorado-based company that sells CBD oil and capsules, for the test.

Earlier this year, Carl’s Jr. also debuted a plant-based alternative to its beef patties when they partnered with Beyond Meat.
