Rey Mysterio failed WWE drug test for amphetamines over 10 weeks ago
According to Dave Meltzer on his latest radio show, Rey Mysterio's failed drug test was for amphetamines and happened when he was visiting friends backstage on the February 13th Raw tapings in his hometown of San Diego. Given that urine samples don't take over ten weeks to analyse, this means that WWE must have sat on the results for several weeks before announcing the failure publicly.
