I was on probation back on the 18th, tested negative on the 6th, then tested positive on the 20th. Dont forget that they expanded the metabolites that they test for between these dates, is what they told me over the phone, although the website says this was updated on November 22nd. I got ahold of John W Huffman, yes, the creator of JWH, and he said that he has heard of false positives, yet isn't sure of the exact cause and recommended a good lawyer was all i can do. I had been skiing for nearly the whole weekend before the positive test, so maybe the exercise burned some of the fat cells releasing the JWH?
