Co2 is the way to go for a clean extraction but it is less aggressive a solvent so the purity, without using any sort of winterization method that removes terps, will not be typically as potent. It can be made into a "goo" if it is kept in a vacuum to remove the h2o to create a dabbable product, but because if requires more to produce less it is therefore more expensive but at least you don't have to worry about residuals, (measured in parts per million, butane etc)
