No. You are not allowed to make concentrated cannabis at home. Only State-licensed businesses may manufacture concentrated cannabis. The AUMA prohibits the personal use of volatile solvents like explosive gases (i.e. butane, propane, xylene, styrene, gasoline, kerosene, O2 or H2) and dangerous poisons, toxins, or carcinogens (i.e. methanol, iso-propyl alcohol, methylene chloride, acetone, benzene, toluene, and trichloro-ethylene) to manufacture concentrated cannabis. The County of Santa Clara similarly prohibits the use of compressed flammable gases or alcohol to make concentrated cannabis by way of a solvent-based extraction method (Ord. Code § B26.5-4). At-home hash oil extraction has caused numerous fires and explosions throughout California and Santa Clara County.
