That's rather interesting, especially since a number of witnesses and Conservative members are trying to point out that it's harmful to a person's health to smoke marijuana, even if it's just a few times a year.
The study showed that the three young adults who smoke marijuana one to four times a year had the same results as the eleven others with respect to brain activity. I find that very interesting. Thank you.
I was talking about prefrontal activity. There are obviously a number of things that can increase brain activity. I don't know all of the substances, which is why I want to get your opinion.
If a person consumes a large quantity of sugar or caffeine shortly before undergoing an MRI, can it affect brain activity?
