Thank you, doctor. You study the brain, not just emotions, but the physical brain, the actual biology of the brain. I've got a lot of questions for you about that. But let's just start with cannabis. What are the effects of cannabis on the brain, marijuana on the brain? So I published a study on a thousand marijuana users compared it to our healthy group.

Every area of their brain was lower in blood flow and activity.

And then just this year.

But measurably.

Measureably on the imaging study we do, which is calledACT, S-P-E-C-T, single-photon emission computed tomography.

It looks at blood flow activity, but also looks at mitochondrial function.

Okay. mitochondrial function. I have to ask you to stop. Pardon my ignorance, what's mitochondrial function? So the mitochondria, little energy powerhouses in your cell, they activate and keep the cell,

energized and alive. And 49% of the tracer that we do this study with

is actually taken up by the mitochondria in the brain. So when we see low activity,

it's really low activity along with decreased blood flow. And then there's a new

study by a completely separate group than ours on a thousand young marijuana users,

and the areas of the brain involved in learning and memory were low and blood flow and activity.

So it's not just me because I have a problem with marijuana. It's other scientists as well

saying marijuana is not great for the brain.

What are the effects of less mitochondrial activity and lower blood flow?

So it can go with tiredness, it can go with low motivation, it can go with depression over time,

it can go with more anxiety because your brain can't settle it down.

And in vulnerable people, it can go with an increased risk of psychosis.

How does that work? We're all of a sudden seeing, because marijuana is not a drug, it's a medicine, we've been told.

It's the most healing medicine ever discovered.

It's, quote, natural.

God made it.
