I think this was it, but I’m not sure. Google has decided it would rather be an adservice than a search engine.

The rest of the studies I have found say that drug-testing is simply ineffective and bad for morale.

Thanks Reagan. Fun fact, in the mid 80’s Reagan’s administration did a big study to show how effective drug testing in the workplace was, and how much it raised productivity. When they got the results back, it found productivity had dropped, and workplace safety hadn’t changed. The results said the program was a complete failure. They tried to bury the report and not release it. Rolling Stone magazine sued the government to get a copy, since it was made with public money, and won. They were the only media outlet to publish the results.

They make wall plug adapters for them, no more batteries.
