ABSTRACT
Over the 20-year life of modern workplace drug testing, a body of law has been created that is directly related to and directly influences its practice. It is an expansive body, stretching from the constitutional limits on the government’s ability to require testing under the Fourth Amendment; it involves a large and expanding matrix of state drug testing laws and legal cases, and travels all the way down to local rules establishing how to introduce drug test results in an unemployment security case.
