My next question is with regard to the per se limits of THC. I know this will be set by regulation, but your department has already identified some numbers. Bill C-46 can't be seen in isolation. Of course, you introduced it on the same day that Bill C-45 was introduced, and I know you want to have this law in place before Bill C-45 becomes law, but the changes to Canada's marijuana laws will be quite a revolutionary thing. I agree with the approach, the overall goal that Bill C-45 has, but if cannabis is legal in Canadian society, it needs to be accompanied by that public awareness campaign, because I don't think a lot of people see the strong correlation between how much you can ingest or inhale and what constitutes impairment.
What studies or evidence does your department have correlating these specific numbers to impairment? Whether you eat something or smoke something, whether you're a habitual user or first-time user can have a different effect on how much of the drug is in your body, and it also could be very different to what constitutes impairment. How has your department examined that particular issue?
