JACKIE CALMES:

Well, it's bigger than I thought! Clearly, because this whole subject came to me in a completely separate news story I was reporting. And employers, local leaders, just volunteered to me that as the unemployment rate came down, the biggest hurdle they were facing in finding – in filling jobs was finding people who were willing to take a drug test, and if they did take a drug test, could pass it. And I thought, well, that can't be as big a problem as they're making it out to be.

So a couple of weeks later when I had some time, I started making calls around the country. This initial tip was in Indiana. And it was like shooting fish in a barrel; it was so easy to find employers to tell me it was a problem.
