cannabis oil...

This is sifted through a piece of nylon stocking or a very fine mesh screen. Many times the taste of the hashish is improved if the oils giving the marijuana its taste and smell are removed from the dust. This is accomplished by extracting it with alcohol in the stew-pot apparatus as described earlier. Further extraction of the compounds contributing to the taste and smell is accomplished by boiling in water. All solvent is removed from the dust first, as the fumes might present a fire hazard. The water is filtered from the dust and the process is repeated with fresh water until the water remains clear, indicating that all soluble substances have been leached from the cellulose material. The cannabis dust is thoroughly dried, and is then ready to be mixed with the oil. The mixing is facilitated by first heating the dust and oil and then working them together in a large mortar, or by kneading the mass with the hands. Thin, fiat, hand-pressed patties like those from Afghanistan may be fashioned, or one may mold clumps of “fingers” or round “temple balls” such as those found in Nepal. Flat sheets and blocks may be formed by pressing the mixture between two heated steel plates in a vise.
