Madam Speaker, I am very much in favour of the legalization of marijuana, but I am also concerned, as I think all Canadians are, about the safety of Canadians on the roads and impairment while driving. What I am concerned about with regard to the bill before us, and what I have heard from the other side, is that the government is prepared to go ahead using per se limits for THC levels in the blood and relating that to impairment. However, we heard at the justice committee that this simply cannot be done. If we do that, we will be criminalizing people who are not impaired and who pose no threat to other motorists and are acting legally under the law, in that we have made marijuana legal, or will have within a year. This is my concern. We have to test for impairment rather than for THC levels.
