From a report at the link below:
Cocaine was found on the floor near a bathroom in a restricted area of the Kennedy Space Center according to NASA officials.
"It's unacceptable," NASA spokesman Allard Beutel said.
The cocaine was found in a plastic bag on the floor near a restroom inside the Orbiter Processing Facility, where space shuttle Discovery is being prepared for launch in March.
The presence of illegal narcotics is considered a safety hazard because astronauts' lives depend on the precision work done in the hangar.
About 200 employees were working in the hangar at the time the cocaine was found.
