Thank you very much.
In general, the health risks to young people have to do with their developing brains. It's a combination of the fact that it can—through a complex interaction, which the scientists will be able to explain to you much more specifically—have long-term lasting structural effects on their brains, which could then have long-term lasting effects in terms of their executive functioning, etc., as they go through their lives.
What is also, as you alluded to, extremely concerning is their lack of knowledge and information about those risks. It's always a mistake to speak anecdotally, but I have a 15-year-old who will say quite openly, “Everybody knows smoking tobacco's stupid, but what's the problem with pot?” I think she is just simply reflective of her generation. I have seen some information and literature that suggests that the myths among youth are prevalent. It's not just about it being harmless. Some of them actually think it's healthy, perhaps a cure for cancer.
They simply just do not understand the facts, through no fault of their own. I think the particular harms for youth are a relatively new and emerging science. I think the consensus—as with anything in science—needs time to develop, needs repeated trials. But I was struck at the round table that the minister had yesterday, where the scientists said the debate is over.
