(CNBC) Carl’s Jr. is adding something special to its signature sauce.
The restaurant will test a CBD-infused burger at one of its Denver locations for one day only: April 20, the unofficial holiday for cannabis enthusiasts.
The limited-time offer makes Carl’s Jr. the first national fast food chain to add CBD-infused food to its menu. In another nod to the marijuana holiday, the burger will sell for $4.20.
