I am drug tested randomly by the person in authority over me. They have good reason to do so, as I do have a history of some drug use. However, I haven't done anything for a while. Not a huge, but decent amount of time. But now I have a big problem, I tested positive for PCP twice now and I have a third test coming very soon and I Have to show I have not used PCP, now or ever. I have never done PCP, in fact I have never even seen PCP. The closest I have come to it is hearing second-hand talk about smoking weed with it. So, if anyone knows and can tell me what might trigger a false postitve for PCP, please, please, let me know what they are. Or if you know somewhere I can look it up, or anything at all that might help. Thank you.
