Health committee  Table 3...the performance?

Health committee  That's the standard error?

Health committee  I think that the actual p-values speak for themselves. They're not even close to being significantly different, so I think it's reasonable.

Health committee  There is another study also—the one on the visuospatial working memory task. I don't know if you've read that as well.

Health committee  Yes.

Health committee  When we design fMRI tasks, typically we want both groups to be able to perform the tasks so that we're actually looking at activity in the brain related to the type of processing we're interested in. We design the tasks so that they're not necessarily simple, but doable. We want

Health committee  We had to take into account nicotine use and alcohol use because they do impact the brain. We were able to control for a number of substances, a number of variables, in our analysis. We have seen that nicotine use does impact the brain, particularly in high doses. We're just ma

Health committee  Do you mean something like a Bonferroni correction?

Health committee  There are cannabinoid receptors all through the brain, the prefrontal cortex, the hippocampus, the cerebellum. The cannabis affects the neurotransmitter modulation. Do they actually destroy neurons? In animal models, they have been shown to. I think what Dr. Sabet was saying ab

Health committee  I think we do have a number of longitudinal studies that suggest there are negative long-term effects. Is there more evidence that has to be gained? Of course. But we do have quite a bit of scientific evidence to suggest that there is long-term impact.

Health committee  No. None of them were using any kind of prescription medication.

Health committee  Just to clarify, are you asking whether the government, in putting in this program, based it on scientific evidence? Do they have the scientific evidence?

Health committee  That's a tough question. I'm not sure that the scientific evidence was there at the time. I think we have it now that marijuana is dangerous. Again, I think we really need to separate medical marijuana from the use that is going on in youth. I think they are very different situa

Health committee  The groups that we had were smoking more than one joint a week. That's what I can say—
