Abstract: Systems and methods for removing one or more pesticides from a cannabis product are provided. The method includes dissolving, in a solvent, a cannabis product including one or more pesticides, forming a dissolved solution, and cooling the dissolved solution to a cooling temperature, causing the cannabis product to precipitate from the dissolved solution, wherein, at the cooling temperature, the one or more pesticides remain dissolved in the dissolving solution. The method further includes removing the precipitated cannabis product from the dissolving solution. The disclosed method is suitable for removing one or more pesticides from various cannabis products containing natural cannabinoids, cannabinoids acetates, cannabinoid carboxylates, or the like.

Abstract: This disclosure provides a method for converting CBD to a tetrahydrocannabinol featuring the use of cheap and non-toxic aluminum isopropoxide as a catalyst. The method comprises (a) providing a reaction mixture comprising a catalyst in an organic solvent, wherein the catalyst comprises aluminum isopropoxide; (b) adding a reagent comprising CBD to the reaction mixture; (c) mixing the reaction mixture and allowing a reaction for converting CBD to a tetrahydrocannabinol to occur for a predetermine period of time; (d) removing the catalyst by filtration upon the completion of the reaction; (e) removing the organic solvent; and (f) eluting the tetrahydrocannabinol from the organic phase.

Abstract: This disclosure provides methods and systems for the supercritical fluid extraction of cannabinoids from cannabis. The supercritical fluid extraction of cannabinoids is performed with carbon dioxide (CO2) balanced with one or more hydrocarbons, such as propane, propene, and propadiene. As demonstrated, the extraction can be carried out at maximum efficiency and energy savings while keeping the wax formation at minimum by lowering temperature. The methods and systems disclosed herein reduce the production time and safety/environmental hazards and are suitable for proper and safe extraction in non-GMP and GMP environments.

Abstract: Systems and methods for removing sulfur from a cannabis product are provided. The method includes dissolving, in a solvent, the cannabis product including sulfur, forming a dissolved solution, and mixing an oxidation agent into the dissolved solution, causing the dissolved solution to form into a plurality of solutions. The plurality of solutions include a water solution and an organic solution, the water solution includes sulfur, and the organic solution includes the cannabis product. The method further includes removing the water solution from the plurality of solutions.

Abstract: This disclosure provides cannabinoid compositions with improved shelf-life stability, methods of use thereof, and methods of preparation thereof.
