The present invention provides cannabis oil extracts and compositions thereof, including cannabis oil compositions containing vitamin E, and methods for preparing the extracts and compositions. In some embodiments, the present invention provides a method for preparing a cannabis oil extract comprising eluting cannabinoids from cannabis plant material with a solvent to produce an eluate, filtering the eluate with a filter to produce a filtrate, evaporating the solvent from the filtrate with a distiller to produce a distillate, and purging the distillate under conditions sufficient to remove residual solvent, thereby preparing the extract. In some embodiments, the method further includes mixing a quantity of vitamin E with the extract to produce a cannabis oil composition.
