1. A method for purifying terpenes, comprising:

providing cannabis material having a detectable tetrahydrocannabinolic acid (THCA) content;

adding a solvent to the cannabis material;

enclosing the cannabis material in a filter bag, the filter bag having a pore diameter of between 20-30 microns;

spinning the filter bag in a centrifuge to separate the cannabis material into tetrahydrocannabinolic acid (THCA) and a high terpene extract (HTE);

depositing the high terpene extract on a tray;

heating the high terpene extract in a vacuum oven, and reducing pressure within the vacuum oven to volatilize most of the terpenes in the high terpene extract;

pumping the volatilized terpenes from the vacuum oven to a cold trap and condensing the volatilized terpenes in the cold trap to yield condensed terpenes, and

cooling the condensed terpenes at a temperature between −50° C. and 0° C. to remove water from the condensed terpenes to yield purified terpenes.
