Diddy is speaking out on behalf of track star Sha' Carri Richardson , who was recently banned from participating in the Summer Olympic Games in Tokyo after a positive marijuana test. The Bad Boy Records founder took to social media to express his anger and frustration with the demonization of marijuana that eventually ended Richardson’s Olympic hopes. "It's f**ked up and my heart is broken for @itskerii having her lifelong dream stripped away for using a legal substance," the 51-year-old tweeted on Wednesday.
