I agree that marijuana should not be considered a performance enhancing drug. It sounds like she took the edible in a state where it is legal to do so, to relieve anxiety and the pain of grieving for her mother.
Would the committee tell an elite athlete who struggles with anxiety that they cannot take a government approved, ‘legal’ pharmaceutical for their condition? Probably not.
Cannabis has been vilified for so long, for no reason whatsoever and it breaks my heart after all the time, heart and perseverance that she will not be able to compete, especially since the stigma around this drug has disproportionally impacted African-Americans lives and livelihoods.
