Carl’s Jr. is making history this 4/20.
On Saturday, Carl’s Jr. will debut the CBD-infused Rocky Mountain High: CheeseBurger Delight at a single location in Denver, Colorado. The CBD Burger will be available for $4.20 during the one-day test, fittingly held on April 20, a weed-filled celebration for many Americans.

With the test, Carl’s Jr. will become the first major fast-food chain to roll out a cannabis-infused menu item — even if just for a one location, one-day event.
