Thank you very much.
Thank you for coming.
It's quite an honour to be able to do this today, because I had asked that the committee study this. I come from Winnipeg, and I spent 20 years as an emergency doctor in Winnipeg. One of the really surprising and rather frightening things is the rate at which this has taken off. I last practised emergency medicine three years ago, in the inner city at Health Sciences Centre. It really wasn't a big issue then. It was something that I didn't see. The substance itself has been around for.... I learned about it in residency 20 years ago. For a lot of reasons that we're still trying to figure out, it's just exploded.
Ms. McDonald, has anyone been able to figure out why there has been such a sharp increase in the use of this particular substance?
