You seem like a good lil researcher, go find them yourself. Everyone here hates doing a little work.
And, your saying its cool to smoke up outside of testing periods, but not during..ok...got you...Micheal Phelps went and got lit right after the games and stayed high for months before he faced any ban/suspension, and he got "clean" just in time for the next games. It should not matter when or why you use marijuana. Its time to reverse the ban, let the best race.
And incase you didn't know , The IOC sets the rules globally via their independent sporting bodies. They pass those rules down to each individual nation, thus it starts with the IOC and ends with the IOC. IDGAF that USADA disqualified Richardson, they were following rules set by the IOC who founded the World Anti-Doping Agency who put the rules in place. Connect some dots next time.
