HELEN WHITE (Labour) (remote): Thank you, Madam Speaker. I'm going to do the unthinkable and agree with David Bennett, because the technology that has evolved around saliva testing has really changed over time. What we now have is we have technology that means you don't have to be so invasive with people and that's reliable about something that's actually really helpful, which is recent use of a drug. So the problem with some of the testing in this area, and particularly urine testing, is that you don't actually know from the test whether the person is impaired, and you don't actually know if they've recently used it.
