You mean decarboxylated and if it's incorrectly purged your buddy shouldn't just use it for something else unless he has finished purging it correctly. Sorry but this shit gets under my skin, they're so many half ass oil makers out there supplying patients, it blows my mind. When your making medicine for patients this is not the time for trial and error, you should be past the inconsistencies before supplying patients with solvent made extracts.
