Addiction and Substance Abuse

Possible false positive hair follicle test



I am 31 yrs old a single mother of 3 kids. I was in an abusive relationship, and when I ended it he went crazy and called my probation officer. (The reason I`m on probation was driving on MY own prescription migraine medication and being pulled over for speeding) Anyhow, he told my PO to do a hair follicle test. I had no problem, since I don`t do drugs and never have. I do take Concerta currently for chronic fatigue syndrome, and have for a couple of months. But I just got the test results back and they are positive at a 1459 PG/MG?? for Cocaine. I`m also on Paxil, Adivan, Fiorcet, and have recently been on Antibiotics for an infection for about 3 weeks. I know that Concerta is a Anphedamine?? but I`m not sure if that could have done it. If that`s not possible, I`m wondering if this crazy, abusive man could have set me up as I recently found out he is a cocaine user?? I`m not sure what to do because my PO doesn`t believe a word I`m saying and is making me pay dearly for this positive drug test. Help, I need some answers.
