I got given a load of old leaves & stalks from my friends crop. He said they probably weren't smokable but if I wanted them I could.
I don't know what it's called but i was thinking of doing that thing where you mix all the leaves & stuff in with ice water for about an hour, then filtering it through some cloth to be left with a smokable resedue.
Would this work on poor quality old leaves?
Even to get a bit?
