How much is industrial hemp used in countries where it has always been legal though?

But what countries are that?

As far as I know, most followed US hegemony, and for example in germany it was legal, but very hard to get permission to grow hemp. So only small uses like for making rope and birdfood.

So I also believe demand and supply for various things will grow. I really like for example, that nowdays you can get organic hemp seeds in the supermarket. It gets more in fashion, because it is nice and quite healthy. But no, hemp will probably not disrupt big industries. It might disrupt the alcohol industrie a bit though, when it is widespread legal.

The Soviet Union grew it quite extensively, and I believe both Canada, France, and Australia have allowed its growing for a couple decades now. It doesn't seem like in any of those countries it has lived up to the potential pro-hemp boosters claim.

I dunno, GP is raising some solid points. Why hasn’t this happened in places where the government didn’t clamp down on it?
