We had quite a few submissions from people who were worried about their historic use of marijuana, and they're worried about that because marijuana stays in the fat cells. When it does that, you can't actually tell if the person's smoked a joint quite a while ago or they're actually impaired when they're driving. Now, we have pretty good, robust saliva tests, and they'll show you that there has been recent use of a suite of drugs. That isn't made on a moral ground or a legal ground; it's made on the basis of its impairment. So it's like, basically, this is the rule, people: don't take drugs and drive. They impair you. It puts drugs into the same situation that we have had alcohol for a while, where that message actually needs to get out to the community.
