Yeah, I think there's no evidence for that at all.

And people are surprisingly bad, even experienced pot smokers, at judging in lab studies of like how strong different cannabis is.

Huberman Lab

I don't agree with that part, but I do agree we should think about the edibles differently.

Huberman Lab

because of the onset is different through the gut.

So when you smoke anything, you get that, that goes very efficiently to the brain.

But when you eat something, it takes a while to have its effect.

And so particularly when these products came out and a lot of people were new to them, they would bite down on one piece of whatever the bar, the cookie or whatever,

Huberman Lab

five minutes later I feel the same, take another bite, still feel the same and then just eat the whole thing and then it would all hit them like a train and that does happen.

The other thing that is true is that a lot of these products are not well made or they're not up to like the standards of like you would have a cookie,

Huberman Lab

You would never open up a bag of chocolate chip cookies in the United States and find all the chocolate chips at one end and just dough and the rest, but that does happen with cannabis products in legal markets.

And so if you just bite on the wrong part, you're getting the whole enchilada, so to speak, because it's not evenly blended through.

Huberman Lab

And there are some people who've gotten into trouble on that as well.

Huberman Lab

Interesting.

Huberman Lab

Yeah, so I was very skeptical of this literature for years.

Huberman Lab

Not to say that the science was bad, but just like it seemed to me there were lots of ways to explain it.

Huberman Lab

And I'm a lot less skeptical now, candidly, because, you know, in the old studies, there would be men who had used cannabis in teen years and then they would have higher rates of...

of psychotic disorders in adults.

These were studies based on Swedish registries, because everybody has to register for the military.

Huberman Lab

And they would track people, and it's quite amazing data.

Huberman Lab

So it is a whole national data.
