The American Civil Liberties Union and the Drug Policy Alliance’s 2006 report argued that drug testing is not worth the cost.

Schools risk false-positive drug tests, they say. The tests take dollars away from other prevention programs. They can undermine trust and drive away students who might otherwise have gotten help in other school programming.

“Nothing prohibits it,” said Doug Bonney, the legal director for the ACLU of Kansas and Western Missouri. “But it is a colossal waste of money.”
