A tryst with a woman Shawn Barber met on Craigslist led to a positive doping test for cocaine for the Canadian pole vaulter.
The 22-year-old from Toronto tested positive for trace amounts of the drug prior to the Rio Olympics, but the 2015 world champion was permitted to compete in Brazil after it was determined he inadvertently ingested the banned substance.
The Sport Dispute Resolution Centre of Canada (SDRCC) decision was released Thursday.
Barber wasn’t suspended but was stripped of his 2016 national title.
“This has been a learning experience for Shawn, he is a young athlete learning how to compete on the field of play, and prepare away from it,” Athletics Canada said in a statement.
