Then it’s time to get stuff done, take a few pulls of this Dyna Puff Green Crack Cartridge. The potent, uplifting effects of this celebrity cultivar are perfectly retained thanks to Dyna Puff’s CO2 extraction process, which results in oil that tests between 75-85% THC. Dyna Puff CO2 oils are tested for potency and purity and compatible with most standard vape batteries.
