False positive on UA - why?

[rincewindrocks]

So this morning I had to take a 5-pin test UA. The 5 drugs it tests for are THC, Cocaine, Opiates, Amphetamine, and Methamphetamine. I came up clear and strong on Opiates, Cocaine, and Amphetamine, but my THC was faint, and my Methamphetamine line was barely there...like, you could only see it in the light with your eyeball right up to it faint. They gave me a 2nd test, same thing. Luckily, my CCP tracker let me go, but to avoid this happening again, I was wondering why this might have happened.

I have been clean and sober of everything except cigarettes for almost 3 months now, haven't used weed in about 5, and havent used meth in over a year. I have not been taking any meds, including OTC. I have been drinking energy drinks, specifically NOS, but I don't see anything on the label that would give a false positive. The only thing that might (and i stress might, i dont think so) be affecting this is I've been drinking alot of coffee at work. When I clean my glass, I generally just rinse it and then dip it in the sanitary water in the washroom (I work in a restaurant). Other than that, I'm confused. Any suggestions, or questions that might get me closer to the answer? My tracker basically said if it happens again, he's going to order lab test and take me to jail while awaiting the results, and while I know I would come up clean, I obviously dont want to sit in a cell for three or so days waiting.

Thanks in advance

Hello, you should know better by now that Urine Analysis questions are not allowed on BDD. Nobody here can know what could have caused you a false positive, it would just be speculation.
