Cartridges are prefilled cannabis oil devices that attach to a battery (or come in all-in-one varieties.) This popular consumption option is known for its fast, discreet, and potent qualities as the oil is vaporized and also considered less harmful. Most cartridges and batteries fit a “510 thread” or standard style, but there are multiple proprietary types including Airo and Pax brands. Please check with your budtender to ensure your products are compatible.
