Thank you.
Picking up on where my colleague Mr. Oliver was going, it strikes me as intuitive that you wouldn't want to damage your brain by taking anything that might alter your consciousness, and that as a young brain is developing it would be susceptible to more damage. That would be the thesis that I would have in my mind, but I want to test the science a bit on this.
Are there actually long-term longitudinal studies, peer reviewed, that show the impact of marijuana on developing brains? I'm curious as to how those studies would even have been conducted, given that marijuana has been illegal and given the ethical considerations. I mean, you can't have a control group of 15-year-olds that you're giving marijuana to—or not.
I'm just wondering about this. It's not that I doubt the intuition of it, but I am curious. As a health committee, we try to look at the science. How settled is the science on the score of the impact of cannabis on brains and brain development?
