Abstract
A slurry is made with ground cannabis biomass and a non-flammable co-solvent. The non-flammable co-solvent is made up of water and ethanol. The ultrasonication process extracts cannabinoids by applying ultrasound to the slurry. The slurry is then filtered, optionally centrifuged, and then distilled to obtain cannabinoid oil.
