Yes, to make the extract vape it must undergo winterisation to completely remove all unnecessary hemp constituents such as the chlorophyll, fats, lipids etc. leaving only the cannabinoids and terpenes out of the full plant spectrum behind – giving us a broad-spectrum, refined extract. Without doing this the extract would damage the vape device.
For the refined extracts, inherently any refinement and purification process will slightly reduce the overall trace cannabinoid spectrum. This applies to all of the cannabinoids in the extract, but they are still in there at lower trace levels than the original extract. Our broad-spectrum extracts may still, in fact, contain very low THC, and overtime shows up on a drugs test.
