Be wary of vaping the third pass distillates from a rig like this as the potency carries into the day FAR longer the closer to absolute (purity) that I get. Something about vaping the absolute is geometrically more potent than say trying to vape twice as much contaminated compound and I suspect that terpenes in the material moderate the effects far more than normally published, at least for me. I am a patient and know immediately what kind of relief I experience. There are many ways to go about obtaining better purity. Here is a sort of step by step to one way I do it.
