No, I don't know the lab name but I have been told it's only for a 3 month period. As this is voluntary it will probably be a government sanctioned lab.I do have really long hair but I'm not worried about any previous consumption, if so it would make it blatant that my usage has dropped to about 10% of what it used to be. The main thing is reducing the THC toxins in the 1 & 1/2 inches nearer the scalp. Is there anything that I can do to help?
