Any product that has had any solvent used on it for the extraction is OIL, not hash.

Hash oil is only made by using a solvent on hash to make oil, oil made from herb is just oil.

Hash is collecting trichs in one of several ways without using solvent.

'Dry ice' or solid CO2 has been used instead of ice in the bubblebag method, search the forums for the thread. Using CO2 as a supercritical solvent (in a liquid state) requires that it be under pressure (3000psi I think), and you aint doin that in a bucket with bags in it.

I would hazard a guess that 99.5% of 'CO2 extracted' resins for sale are actually made with butane and/or iso and relabeled to skirt laws or make people feel less nervous about possible contaminants in the final product.

As for a CO2 method becomming common, I totaly agree with GS: "maybe someday, but not Monday".
