Chief Cannabis Correspondent Ryan Nerz investigates the role of marijuana in the world of athletics. The investigation begins with America's most popular pro sports league, the NFL. Former Chicago Bears lineman Tank Johnson estimates that 80% of the league uses marijuana, and current players Walter Thurmond and Emmanuel Sanders explain that the drug is a useful elixir for pain maintenance and stress relief. Nerz then talks to former Olympic snowboarder Ross Rebagliati, who nearly lost his gold medal due to a positive weed test, and now has interesting things to say about whether pot is a performance enhancing drug. After discussing the effects of concussions versus marijuana use on the developing brain, the episode ends with Nerz's attempt to conquer cannabis-enhanced bodybuilding.
