Co2 extraction - from raw material to concentration

I'm wondering if there would be a difference in the end product (concentration) if we compare raw material from fan leaves to buds?

Making concentration from buds would certainly yield me more THC than making concentration from fan leaves, but will there be a difference in quality is my question?

How much other stuff does Co2 extraction method pull out besides THC, CBD and terpenes?

?

? THC don't grow on fan leaves

But to my understanding there is 1-3% THC in fan leaves.

So if you would have 1 ton of fan leaves, then you should be somehow able to extract 10-30 kilograms of pure THC out of it.

But probably there will be other chemicals present in the concentration too which came in the result of an exctraction out of those fan leaves.

Depends which type of extraction method was used.

My question is about the Co2 extraction method.

So?
