I've smoked fan leaves that get me stoned and some that didn't. Depends on the quality of leaf. Be a good idea to have those large bubble bags. I'm sure something would yeild with those.
A long time friend is a medical bho guy. He tells me that large fans aren't worth the solvent, but that the sugar leaf & the teensy popcorn def are.
A 2 stage trim gives him what he wants. The big fans go for compost, then the small stuff goes for oil. He does nice things for people, so I help the effort. Gotta give it away to keep it.
Have you ever run the results of a fan leaf extraction through the GCMicroscopic examination will tell you whether the fan leaves have trichomes or not.
We extract fan leaves for killer topicals. They give head effect when vaporized, but it is more like a charley horse between the ears, than a high and the taste is not very good.
