A process for extracting a botanical organic compound from cannabis with subcritical liquid carbon dioxide includes providing a pressurizable extraction vessel. The cannabis is placed within the pressurizable extraction vessel, whereupon the extraction vessel is filled with liquid carbon dioxide under subcritical conditions. The cannabis is then allowed to be in contact with the subcritical liquid carbon dioxide for a selected period of time so as to extract at least a portion of the botanical organic compounds from the cannabis into the subcritical liquid carbon dioxide. The subcritical liquid carbon dioxide containing the botanical organic compound is then removed from the extraction vessel, and the liquid carbon dioxide is separated from the botanical organic compound.
