Thank you very much, Mr. Chair. Again, this is another great panel. I wish I had more time to ask questions, but I have a very short period of time.
I want to start by picking up on a point that I think Mr. Howlett made, that with our youth there's a diminished understanding of risk. The CMA was here with very credible witnesses. Dr. Grant, thank you for updating us on the science, about the structural and functional effects, the problems with psychosis, with schizophrenia. I have a person close to me for whom it has been linked.
My concern is still, are we doing enough to help our young people? Talking to parents in my community, some of the comments were that this is a big experiment that Canada is conducting and that very few countries have gone this way. There are a lot of concerns. We can always get easier, but it's tough to get tougher.
You mentioned something that I thought was interesting. Not too many people have brought this up. You talked about higher THC levels and something of known potency. How would you see that being implemented? Should a certain amount of THC concentration be prohibited for those under the age of 25? We've heard that age mentioned a lot. How would you do that?
