This test was sent to a lab and not one that was read on the spot. The results came back positive for methanphetamine and anphetamine as well as methadone. The only one that was in my system was methadone because I am on a maintenance program. I have been unable to provide a urine sample for the random testing because of a prolapse but they have been taking an oral swab test and this particular morning I drank an energy drink thinking with the extra cafeine it may help me to urinate for the regular test so when I was unable to provide a urine sample that morning they went on to take the oral swab again and the results came back positive for those drugs and I have absolutely not taken anything other than the methadone, so I am trying to find out what could possibly cause this.
