I like Vivek think he is very fair and unbiased although I understand that Pac fans dont like him. But what he said was a rumour and one line in the who article and not the title and to be honest cant be true. If Khan had failed a drug test everyone would have known about it by now!
It just tries to open and push the idea that Ariza’s fall-out with Khan had something to do with drugs. And to do this, Vivek fabricates the rumour that Khan failed his drug-test. No facts, no nothing. Just his usual bull**** to promote Mayweather's propaganda.
