there's a way. From the Minneapolis Star Tribune:
Vikings running back Onterrio Smith was detained last month at Minneapolis-St. Paul Airport after police found paraphernalia later identified as a kit used to circumvent drug tests.
Smith was neither arrested nor charged, but as of Tuesday it was unclear whether the incident will affect his status in the NFL's confidential substance-abuse program.
Smith acknowledged to airport police that he was carrying dried urine, along with a device called "The Original Whizzinator" and a bottle of pills labeled "Cleansing Formula." He told police the kit was "for making a clean urine test," according to the police report, and said he was taking the materials to his cousin.
Smith was suspended four games last season after testing positive for marijuana, his second "strike" in the league's program. A third "strike" would result in a yearlong suspension. An attempt to substitute a urine specimen qualifies as a positive test, but NFL spokesman Greg Aiello did not immediately know Tuesday whether possession of a masking device fits that criteria.
Oy! He was taking the materials to his cousin???? If true, it shows a serious lack of sagacity, given that he already has two strikes against him.
