Do you know how long it takes to filter out of your system? If you read the article you would have notice "Williams is tested nine times per month on a random basis. The man who administers the urinalysis for the NFL sometimes shows up at Williams' home before dawn"

So thats an average of 1 test every 3.2 days, far quicker than it takes for marijuana to clear out of your system. RW keeps it real and no matter what people say de dude is ah honest fella. I would love to see him have a good year as the final display of how far he has come back.
