She got banned for weed which I think wasn't right. You should only be banned for things that enhance you like steroids not hurt you. You can have any amount of alcohol in your system and still be qualified to run. Also, she had a messy public break up with a Jamaica runner in an American college coincidentally
I like a good turnaround story for any black person. African female runners are getting their weight up. They don't have the infrastructure but once they do, especially west Africans which are very close to the American and Caribbean phenotype for obvious reasons (slavery), they will be very, very good. Much larger gene pool to choose from. Nigeria alone has 4 x the population of all blacks in America.
Anyway, congrats to her. Track is one of those sports there is no gray area. Fastest wins.
