Michael Phelps just won his 21st gold medal as the 2016 Olympic games continue in Rio. All the while we wonder how the heck he does it!? We all remember the 2009 scandal where Phelps got caught smoking a bong at a University. Is marijuana partially to blame for Phelps’ success? We decided to test out this theory and find out if smoking while we exercise will improve our performance or impair it. Hope you enjoy Episode 8 of Season 2: Stoner Olympics!
