A vape cart is a glass cartridge pre-filled with a gram or half-gram of cannabis oil. This oil contains various combinations of cannabinoids and terpenes extracted from cannabis.
Most oil vape carts are high in THC, however, more and more CBD-dominant vape cartridges are entering the market, as are 1:1 THC:CBD products. Vape cartridges come in many forms: 510-threaded cartridges (the most common), as well as some proprietary forms like Pax Era Pods and Airo Pro oil cartridges.
