Preparation of Translucent (Honey) Oil
One of the most potent and popular of the cannabis oil preparations is a thick, translucent, amber oil which has been extracted from Afghanistan hashish. This consistency is obtained by removing the colored impurities from cannabis oil that has been purified by re-extraction with petroleum ether.
The purified cannabis oil (which may or may not be isomerized or acetylated) is dissolved in ten times its volume of pure alcohol. An amount of granulated activated charcoal (Norit) equal to half the weight of the oil is added to the solution. The solution is filtered through fine filter paper and the alcohol is removed by evaporation. The residue is a translucent amber oil With the appearance and consistency of dark honey.
