They busted some juiced up cops here, and also the cops who were trying to cover it up by munging the piss tests. Drugs stay in your hair as long as the hairs stay. I suggest staying clean and cutting your hair really short, just in case.

No matter what we think about it, the public expects cops to not be juiced up. Especially with all the paranoia about gear brought to fore by the baseball scandals and the revised steroid laws, you would be well advised to stay clean for the time being. If you eat, train, and recover properly, you can still be fairly big and look pretty good.
