Oklahoma Pure has long been one of Oklahoma's best cartridge providers, with full-spectrum and solvent-free cartridge options that are potent yet easy hitters. Their super critical CO2 extraction methods create crisp and pure cannabis flavored cartridges and the optional real and food-grade terpene options give patients a selection that offers everything they'll need. We like Oklahoma Pure for the quality of the cannabis oils that they provide and the pure cannabis flavoring that they deliver.
