Description: GoldCart CBD cartridges contain 100mg CBD and zero THC. Available in a 500mg Pineapple flavor cartridge. TetraLabs CBD GoldCarts are crystal clear, and contain no contaminants and no propylene glycol. Our CBD is refined from natural hemp plant extract. Because TetraLabs GoldCart CBD cartridges contain zero THC, you don’t get the psychoactive effects of THC. But if you do want a combination of CBD and THC, use both a TetraLabs CBD cartridge along with a TetraLabs THC cartridge to achieve the exact CBD-to-THC ratio you want.
