Marijuana is on the World Anti-Doping Agency’s list of prohibited substances. USADA and the United States Olympic and Paralympic Committee are both signatories to the AMA code, which means they follow its rules.

The drug is only prohibited in competition, which is defined as starting at 11:59 p.m. the day before the competition and ending at its conclusion. Athletes can have up to 150 nanograms per milliliter of THC, the main psychoactive substance in marijuana, without causing a positive test.

According to USADA, marijuana is a banned substance because it is considered both a performance enhancing and a drug of abuse.
