Rob Gronkowski, the former NFL tight-end and Superbowl champion, is now advocating for the NFL to allow players to use CBD. He claims that now he has regained his health, CBD is playing a large role in helping him feel better. The NFL remains against its players using CBD oils or eating CBD edibles. Other sports leagues and their drug policies are lightening up though, including WADA which regulates controlled substance use for athletes in the Olympics along with many of sports leagues.
