Iso hash is obtained through the extraction of isopropyl liquor. QWISO is an acronym for Quick Wash Isopropyl Alcohol hash, a well-known method for producing isopropyl alcohol hash. Utilizing liquor as a dissolvable is extremely sloppy; however, the flavor is inferior to that of other solvents/techniques. The item is dependent on the type of cannabis and its extraction. Excellent QWISO is frequently clear and yellow in appearance, resembling a break, with a flexible surface. Iso hash of low quality is frequently green (from plant chlorophyll) or dark, with a sticky surface.
