ST. PAUL, Minn., May 11 (UPI) -- Police caught Minnesota Vikings running back Onterrio Smith with a kit to foil drug tests when toothpaste set off airport security alarms in St. Paul, Minn.
Smith was neither arrested nor charged in the April 21 incident, in which a tube of toothpaste activated alarms before he boarded a flight.
It was unclear whether the incident would affect Smith's status in the National Football League's substance abuse program, the Minneapolis Star Tribune reported.
Smith tested positive for marijuana last season and was suspended four games, his second strike in the program. A third violation would result in suspension for a year.
Smith told airport police he was carrying dried urine, a device called The Original Whizzinator and a bottle of pills to make "a clean urine test."
An NFL spokesman said it was unknown if possessing the kit would violate the league's policy.
