Gold Rush specializes in CO2 Distillate extraction and utilizes the natural terpenes from the cannabis plants used to create their strains. Each cartridge contains the perfect amount of terpenes added back in to help provide effects and benefits similar to those cannabis flower when inhaled. Flavors are strong and crisp, with each inhale being smooth to the throat and mouth. We like Gold Rush because it provides a quality cartridge that keeps patients in mind when being made.
