Hash, or Hashish, is the baked "kief" removed from trim leaves. Kief is removed trichomes. Still on the plant, those little resin glands, that we call "the crystals" are called trichomes while still on the plant. Aftr they are removed, they are called kief. If you pack them into a patty ro clump or cake, and bake it to harden it, then it is HASH. HASH is a very HEADY High, an engergetic high. We make ti from buds and trim leaves.
We can also take the female FAN leaves, and dry them first, get all the water out of them, leaveing the oil. Then by using butane or alcohol, we can process that oil out, and dry that oil into a tar, we call hash oil, but it is not really hash. It is such a dark green, we call it black. It is a body high, a knock you out high, a sofa-lock high, mostly containing canabanol, and very little THC, that works on the body.
IF you add some trim leaves to the oil, or buds, or kief, it will be brighter in color and that is honey oil, a combination of body and mind high.
