Hash oil is a resinous
Resin
Resin in the most specific use of the term is a hydrocarbon secretion of many plants, particularly coniferous trees. Resins are valued for their chemical properties and associated uses, such as the production of varnishes, adhesives, and food glazing agents; as an important source of raw materials...

 matrix of cannabinoids produced by a solvent extraction
Liquid-liquid extraction
Liquid–liquid extraction, also known as solvent extraction and partitioning, is a method to separate compounds based on their relative solubilities in two different immiscible liquids, usually water and an organic solvent. It is an extraction of a substance from one liquid phase into another liquid...

Solvents

The most common solvents used are butane
Butane
Butane is a gas with the formula C4H10 that is an alkane with four carbon atoms. The term may refer to any of two structural isomers, or to a mixture of them: in the IUPAC nomenclature, however, butane refers only to the unbranched n-butane isomer; the other one being called "methylpropane" or...

 or isopropanol. Hash oil extracted with butane is often referred to as butane honey oil, or BHO.

There are a wide variety of dangers associated with use of chemical solvents. The most common danger is from flammability. Structure fires and severe burns have been caused when production accidents occur.

Legality

US Federal law classifies cannabis as a schedule I controlled substance, and possession constitutes a crime.
