CO2 is a naturally-occurring substance, and can be used as a non-toxic solvent to create concentrates. During the extraction process cannabis is washed with liquid CO2, which separates the cannabinoids and terpenes (the good stuff) from the rest of the plant material. Any CO2 that’s left in the oil will evaporate, and you’ve got a solvent-free product! This creates a concentrated oil that can be vaped at this point and you’ll get a nice, light amber coloured oil that can run anywhere from 50-70% concentration. All our carts are 510 cartridges (which fit basically every pen) with 0.5ml and feature Indica, Sativa and Hybrid strains. This is a great and discreet option for smoking on-the-go and work perfectly with our batteries.
