Anthony Johnson shocked the mixed martial arts world by announcing his retirement in April following a second round submission loss to Daniel Cormier at UFC 210. Rumble recently revealed he's getting into the medical marijuana business. “My friend Paul, he’s in cannabis, we’re opening up a facility. It’s for medical uses," Rumble told WWE star Booker T. "We’re playing by the books so that way there is no issues. We’re good to go."
