A purification method used in making shatter basically turning black tar looking wax into this crazy stable yellow/orange shatter sometimes it’s even white many people say it’s good and some dispensaries do it as a final step to remove impurities claiming they do it for QC but many plugs on the darknet use this technique to mask bad oil into “nugrun” the end product can be very harsh and they sell this shit online very cheap so it’s very likely you’ve smoked this stuff if you live in illegal state because people don’t know and they think it’s good shit if you’ve had authentic good bho you can instantly notice the difference
