What does "CO2" mean?
Definition: CO2 refers to cannabis extracts: specifically, the solvent used during the extraction process. Whereas BHO extracts use Butane, CO2 extracts use CO2, a solvent which is gaseous at room temperature so it will eventually evaporate. Also, CO2 is not flammable so the risk of blowing yourself up is much lower.
