I always see those kinds of policies like a "Get out of Jail" card for the employer. They have a policy of testing on their books, so if taken to court they can point to their policy. They never enforce testing, because they know it would destroy their workforce. Yet they still have the option of selectively and "randomly" selecting a bad employee for a drug test, and if they fail they have a free pass to fire them and not pay unemployment.
