Now, the problem with that testing, of course, itself was evident to the full court. It is a very invasive form of testing, and we've heard a little bit about that today. It does involve, really, a balance between the employer's interests or the public's interests and the private interests of the employees. What the court warned in that case was that while drug testing at that point was accepted in quite prescribed circumstances, it was not for ever. In fact, what they said was that as soon as saliva testing became reliable, it should replace this form of testing, because it's a lot less invasive. We now have actually really good saliva testing available. It's going to be cheaper for employers. It's way less invasive, because it is only saliva. It's on the spot, so there's a lot less chance that you can actually fiddle with the tests. And, also, it does something very important: it focuses on recent use. There's all sorts of issues with testing with regard to picking up historical use—particularly of marijuana, because marijuana stays in the fat cells—and so it is actually a very bad indicator of whether there's impairment in the workplace.
