Olympic athletes in the 2016 Summer Games in Rio will be able to compete, even if they test positive for cannabis use – but no, you won’t get to watch Michael Phelps swim stoned.
Although cannabis remains on the banned substances list, a 2013 policy change by the World Anti-Doping Agency (WADA) raised the limit of marijuana allowed in an athlete’s system to 150 nanograms of THC per milliliter of blood. This means that as long as an Olympian does not show up in Brazil stoned, or get high during the games, Olympic officials will ignore positive marijuana tests results.
“Our information suggests that many cases do not involve game or event-day consumption,” said WADA spokesman Ben Nichols. “The new threshold level is an attempt to ensure that in-competition use is detected and not use during the days and weeks before competition.”
