When the cannabis advocates and activists fought tooth and nail to convert marijuana from a weapon in the dug war to a medicinal treatment for patients in need, this is probably what they had in mind.

In the culmination of decades of political progress, Carl’s Jr. is unveiling a CBD burger to promote itself on the holiest of holy stoner days, 4/20.

The “Rocky Mountain High: CheeseBurger Delight” will be available for exactly one day in exactly one franchise location in Denver. It will run you, naturally, $4.20.

The CBD isn’t in the meat itself (though those stressed slaughterhouse cows could probably use a little cannabidiol in their system). Instead, the cannabis compound will be infused in the special “Santa Fe Sauce.”

The Rocky Mountain High (which, by the way, doesn’t get you high) also comes with two beef patties, topped with pickled jalapenos, fries, and pepper jack cheese.

Though cannabis and fast food have had a long and mostly happy relationship for generations, Business Insider reports that this is the first ever cannabis-infused product ever released by a major fast-foot chain.

The CBD burger is only a one day offer for now, but the restaurant says it will be watching sales with an eye toward a more permanent menu item. The extract used in the special sauce is derived from hemp, so nationwide implementation could be possible, legally speaking.

“If anyone is going to do it, I would want Carl’s Jr. to do it,” said Patty Trevino, Carl’s Jr.’s senior vice president of brand marketing.

The burger will go on sale at the restaurant’s location on Colorado Blvd. in Denver, beginning at 6 a.m. on Saturday.
