Hash oil is one of the most potent forms of (medical) marijuana. The oil is highly concentrated, with THC levels between 40% and 90%. This makes it a powerful medicine to be used with care and wisdom. Hash oil is a resinous matrix of cannabinoids produced by a solvent extraction of (medical) marijuana. The oil varies in appearance from a crystal-clear, glossy amber to gold resin, and is usually very thick and viscious. The best quality is transparent and relatively free of impurities.
Hash or honey oil is a wonderful ingredient in cannabis cooking. It can be mixed into various baked goods or spread onto food. Hash oil can also be smeared or dabbed on a cigarette or joint and smoked. It is also possible to vaporize the oil using a vaporizer, bong or bubbler. Please be careful to make sure you get the dose right. It's easy to get a good level of pain relief with hash oil, so don't waste any by using more than you need.
The psychoactive components of medical marijuana are called cannabinoids. To make hash oil, the marijuana plant material is finely ground, and a solvent is used to isolate the cannabinoids. The most common solvent choices are Iiopropyl alcohol, butane, ethanol, petroleum ether and naptha. These are commonly available in drug or hardware stores and have relatively high purity levels.Honey oil, also known as BHO, is a specific type of hash oil extracted with butane. Naphtha-based oil notoriously contains residual naphtha (enough to influence the oil's smell, taste and effects). Many users report headaches and nausea from smoking oil extracted by naphtha. In general, naphtha-based oil poses a greater health risk than butane-extracted oil. Alcohol-extracted oil contains plant sugars, which caramelize when smoked to produce a harsh taste.
