    After evaporating off the solvents and purging, the middle fraction noted in the video yielded a pale yellow extract of considerable potency. It is sticky but fluid at room temperature and is substantially free of reapiratory irritants. VERY potent medicine.

    The first fraction shown becomes orange when solvents are removed and there is very little product. This fraction has a particularly foul odor to it and I will discard it

    Here is the middle fraction from the above video. All solvents removed by heating very hot then hard vacuum and repeating four times until extract no longer bubbles while hot and under high vacuum. From the vaping I judge that the extract in the photo is as close to pure cannabinoid as posssible.

    What happened to your YouTube videos? Do they exist somewhere else?
