Like many celebrities these days, Mike Tyson is in the marijuana business - but he's having trouble selling his wares in the country's most famously weed-friendly state. The state of Colorado has banned Tyson's new line of cannabis gummies, which are shaped like human ears with a bite taken out of them. The gummies are a callback to Tyson's infamous 1997 ear-chomping incident with Evander Holyfield. But the state of Colorado doesn't allow the sale of marijuana edibles shaped like humans, animals, or fruit - out of concern they could attract children. Tyson's camp is planning to re-release the product later this year, changing the shape to a letter 'T'.
