I don't know if it does or doesn't but my potential employer has asked me to retake the pre-employment drug test 3 times already because my urine is "too diluted." I don't do drugs. I happen to be taking the acai berry 14-day flush just for diet purposes, but it is the only thing I can think of that is bringing about this "non conclusive" result on my drug test. So maybe, it is something that can be used to flush your system or mask a drug test. I am going to take the test again in 2 days and I've decided to interrupt my flush to see if that will give me more concentrated urine. I'll update on this site after Friday 2/12/10.
