Thank you very much, Mr. Chair.
I want to thank the witnesses for being here. At the end of the day, we really want to focus on the health and safety of Canadians and, for me particularly, our kids. I don't think there's a lot of argument out there about medical marijuana and adult responsibility. I look back at the Prime Minister's rationale for doing this and I asked witnesses today, and it keeps coming out, he keeps repeating that the status quo is not working.
I really want to thank witnesses this afternoon. I think it was you, Mr. Lucas, who quoted some well available statistics that show it's trending down and, depending on which ones you want to quote, as high as 50% of boys in 2002, I believe, down to 22% today. The Prime Minister's rationale is saying the status quo doesn't work. I find it quite interesting that Ms. McLellan, who's a former Liberal cabinet minister, was almost giddy here today saying we got a letter from Colorado saying it hasn't gone up. Well, guess what? Legalization in Colorado hasn't shown a decrease in the use of cannabis by kids, so I think this is really important that we dig into this a little more and also dig into the provincial jurisdiction.
I found it a little rich that the federal Liberals were criticizing the provinces on this, because there's so much science that still isn't known. So much of the heavy lifting is with the provinces and territories, so I want to take this opportunity to thank Saskatchewan for actually showing up here today. We've invited other provinces and territories and I think you're the only one that's shown up. I know my own province of Ontario just passed a little preliminary thing. They don't even want to show up here and answer some questions on it.
With you taking all the heavy lifting, I was wondering if you can go over some of the concerns that you may have with controversial things like home cultivation, and legal age of possession as well. You mentioned in your opening the drug levels and the levels in blood and how controversial it is. Are we going to be seeing a lot of court challenges on these things as far as enforcement?
