When the U.S. Navy began its random drug testing for all personnel in 1982 the rate of positive samples was 7.21 percent. After 21 years of the urinalysis screenings, less than one half of one percent now come back positive.

The random testing is part of the Navy's zero tolerance program, which also includes prevention education and leadership awareness. All personnel found guilty of a single incident of drug use must be processed for administration separation.

Sailors are subject to up to two tests per year. There are no warnings or excuses accepted. Each month a computer picks 20 percent of sailors assigned to a command for the random tests.

The Navy approach "focuses not on solving the program, but preventing it from happening. It's a great deterrence," one sailer told the Star-Bulletin.
