Banana Split Full Spectrum Amber Oil cartridge: Banana-tangie taste and effects of muscle relaxation and the munchies. Our Full Spectrum Amber Oil is extracted using CO2 and gently refined in a way that maintains the original cannabinoid and terpene profile of the flower. This leaves us with a high quality oil that provides a more enjoyable, longer lasting high. We are proud to be Humboldt's Original Cartridge brand since 2013.
