Okay. Thanks.
My concern is about that use among young people in particular, and maternal use. These are the comments of the Canadian Centre for Substance Abuse:
Cannabis use during pregnancy has been shown...to affect the development and learning skills of children starting at about the age of three years, and these effects continue at least until the children’s teenage years.
This is a big concern. The numbers from Mr. Sabet were mentioned earlier: one in six teens become addicted, one in ten adults. The adolescent brain is especially susceptible. We're concerned about the myelination in the prefrontal area that could affect them for a lifetime.
My first question—I also want to pose a second one, because time is limited—is the following. Is the delayed myelination in the prefrontal area not of concern to the people at the end of the table? And how do we manage that with young people? That's question one.
Number two is on safety. You mentioned Colorado as an example of no harm done, but the evidence presented by Dr. Sabet was that in fact vehicle accidents in Colorado have gone up. He said: “While the total number of car crashes declined from 2007 to 2011, the number of fatal car crashes with drivers testing positive for marijuana rose sharply.” On the same point, he talked about increased ER admissions: “In 2011, marijuana-related incidents accounted for 26 percent of the total ER visits, compared to 21 percent nationally.”
Perhaps I can ask you for a quick comment on that. Then I'll turn it over to my colleague here if there's any time left.
