Sure. At the federal level the most important thing you could do right now is the mandatory screening both for alcohol and drugs because it's not just alcohol but also drugs as well.
The second thing is, by doing that, you're increasing the ability for the provinces to enforce their laws, target all those people who are driving impaired, and give them the sanctions that make the immediate difference. Vehicle impoundment, nobody wants their vehicle impounded. All of a sudden if they have mandatory screening, they can more easily impound more vehicles to get the message across, to get that education piece up.
We also want the provinces in preparation for the cannabis to have zero tolerance for alcohol and drugs up to 25. That also sends a message. If you choose to drive when you're a young person with one of those substances in your body, you get your vehicle impounded.
