That should be the point of the law. But when you read these laws, they're laughable. The drug-testing regimens are totally ineffective. Worthless. And here's the problem, a real, effective testing program that would have any chance of making a difference would cost thousands of dollars a year per person once you throw in tracking and administrative costs. I just don't see that as fiscally responsible. Look at the proposed law in PA--not only doesn't it specify a cost or a funding method, it doesn't even lay out a testing protocol. It just says "go forth and test!" How is that in any way responsible legislation?
