Now, coming to this with my sensible drug-law reform hat on as well, we all know—and I've wasted a lot of this—well, I've tried to contribute constructively in this House—the fact that a lot of drug policy is made against evidence and on the basis of moral panic. The thing with this law is that it is currently being made in a bit of a vacuum of evidence. Of course, importantly, all of us in this House seem to agree on the very basis that we want to prevent people from driving under the influence. The problem remains that there is a difference between a substance registering in somebody's system and whether that person is in fact intoxicated or impaired. It's nowhere near as straightforward as the science that we have well established with, for example, alcohol.
