1. A process for producing a cannabinoid infused fat from cannabis comprising:
a) placing cannabis in the interior of a column to produce a packed column portion, the packed column portion being configured or designed to permit a flow of liquids through the packed column portion, the packed column portion including a filter or screen to prevent the cannabis from escaping from the interior of the packed column portion while a fat flows through the packed column portion; and
b) adding a fat to flow through the interior of the packed column portion and to interact with the cannabis, wherein the interaction of the fat and cannabis causes cannabinoids to be extracted from the cannabis and infused into the fat, and wherein separation of the cannabinoid infused fat from the cannabis is achieved by allowing the cannabinoid infused fat to flow out of the interior of the packed column portion, wherein said fat is selected from the group consisting of: cocoa butter, sunflower oil, coconut oil, safflower oil and canola oil.
