I got a dwi last year. i was put on probation for 3 years. The first visit to my p.o. I had to give a urine sample. It was an instant result which was negative, however, the temperature did not come up to where it should have and the P.O. didn't go into the bathroom with me so I had to give a mouth swab. I hadn't and never did drugs so I didn't think anything of it. When I went to see her again, I was told I tested positive for opiates and cocaine. What would cause that? I actually spent $125.00 to have a hair sample taken yesterday which would encompass 120 days and that time frame to prove that I didn't do anything but now I'm worried about that. If I wasn't worried about the mouth swab and it came back positive, why wouldn't any other means of testing do that. I'm scared to death that I will lose my job.
If I have not taken opiates or cocaine but tested positive for them via mouth swab?

I have been taking benedryl, tylenol pm, excederine migraine, tylenol (generic)I can't think of any other over the counter drugs I may have taken. Most of them are generic. Would this cause a false positive. I had a hair sample taken yesterday. Would these over the counter medications cause a false positive for a hair test?

Not quite sure about the facts here... did you substitute someone else's urine? It seems awfully suspect that you say you have never done drugs, and yet you tested positive for two street drugs?? Hard to believe you would be "set up". So, I would either get very honest (with yourself) or the hair sample will prove the other test negative. Maybe they mixed up the swabs, but that would be a rare occurrence, particularly since the urine wasn't the right tempurature (body temp). Maybe they were just "testing" you, but haven't heard of being tricked like that before. Also, try asking a Pharmacist, as they are usually very good at knowing which ingredients may react in which ways. Good luck... let us know:)

I'm sure you have your hair test results by now. I too had a false positive on my mouth swab at work. I went out immediately and had a hair follical test done and it came back NEGATIVE! This was 8 days after they took the swab. I am now waiting for the results on the 2nd test of this original swab that the company I work for are sending to a different lab. The company I work for are saying now that if I had a small enough amount that I had taken that day that it would show up in a mouth swab, but not in a hair follical test.
