Science Doesn’t Support Idea That Marijuana Aids Athletes’ Performance Contradictory data, contested claims and highly speculative research seem to be behind the Olympic ban on cannabinoids. Sha’Carri Richardson at the U.S. Olympic track and field trials last month in Eugene, Ore.Credit.Chang W. Lee/The New York Times July 9, 2021 When Sha’Carri Richardson was barred from the Olympics this month after testing positive for marijuana, it ignited an ongoing conversation about whether the drug should be classified as performance-enhancing for athletes. Does getting high really improve strength, speed, agility or other outcomes? In Ms. Richardson’s case, the answer doesn’t matter, because marijuana is also prohibited, as enforcement organizations assert that it can harm athletes and that its use violates the spirit of the games. Her ban stands whether or not the drug is performance-enhancing.
