FRANKLIN, TENN. — Carl’s Jr. will offer a C.B.D.-infused cheeseburger at a restaurant location in Denver on April 20. The Rocky Mountain High: CheeseBurger Delight features two charbroiled beef patties, pickled jalapeños, pepper jack cheese, waffle-cut fries and a Santa Fe sauce infused with hemp-based C.B.D. oil.

“The new Rocky Mountain High: CheeseBurger Delight ties back to our core strategy of being the first to bring bold and unexpected flavors that are at the forefront of hot restaurant trends to a quick service menu,” said Patty Trevino, senior vice-president, brand marketing at Carl’s Jr. “From our early introduction into plant-based options to bringing the rare indulgence of truffles to our menu with the new Bacon Truffle Angus Burger, our customers have come to expect innovative and unique menu offerings, and we’re thrilled to be the first quick-service restaurant to be testing C.B.D. infused options.”

Carl's Jr. is sourcing the C.B.D. oil from Bluebird Botanicals, a local Colorado company.

While C.B.D. is generating significant buzz of late, its use as a food and beverage ingredient is not federally approved.
