Hash oil is produced by solvent extraction (maceration, infusion or percolation) of marijuana and/or hashish. After filtering and evaporating the solvent, a sticky resinous dark liquid with a strong herbal odor (remarkably different from the peculiar odor of hemp) remains.
How is it used? Marijuana is a mixture of dried-out leaves, stems, flowers and seeds of the hemp plant. It is usually green, brown or gray in color. Hashish is tan, brown or black resin that is dried and pressed into bars, sticks or balls. When smoked, both marijuana and hashish give off a distinctive, sweet odor.
