Mr. Speaker, I wonder if the member could expand on the problem we have. Despite the great need for going after impaired drivers, because we have an epidemic of impaired driving deaths and injuries across Canada, here we have marijuana, which is going to become legal, and there is no good test for marijuana impairment. There are great tests for THC levels in the blood, but they do not mean anything with regard to impairment. We heard in committee that this was a problem.
We are going to have people with THC levels in their blood, because they are using it for medical purposes or are using it legally for recreational purposes, but they will not be impaired. They may have used it a day or two ago. They will not be impaired, yet they will be criminalized if they are pulled over and tested using a per se limit for THC. I wonder if she could comment on that.
