I am actually trying to get help with a hair test, but since I am here, I thought I would let you all know- over the last eight years, I have taken and passed four urine tests, with the second to last test, I smoked up until less than a week before. I have always just went out and got a 90 bottle supply of Vitamin E geltabs and a 24 pack of bottled water, as much before the test as possible. I found this out when at a GNC contemplating buying a $50 drink mix to dilute my system. A man told me to do that, and I have always had no trouble. Once I cut it close, and was scared I wouldn't pass, but it still worked with no problems whatsoever. I heard (but don't know if it is true) that Vitamin E attacks THC. I am suprised I haven't seen this on forums I have been researching. Must be a best kept secret. Don't know if it is good for everyoe, but I have told many people about this and it helped all of them pass. Hope this helps and good luck to everyone trying to pass these.
