Hash oil, CO2 Oil, CO2 Wax

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.

Example usage for CO2

CO2 extraction systems are my favorite machines.
