I was tested for cocaine and it came back positive i do not know how i have not used for 4 months it was a hair test i do not know why? Can u let me know why.

I hope this helps! ## Cocaine metabolites can linger in your hair for a very long time, so there is a c... ...

It has Collodial silicon dioxide, crospovidon, D&C Yellow no. 10 aluminum lake, FD&C yellow no. 6 aluminum lake, magnesium stearate, microcrystalline cellulose, providone. It also states on the package Ephedrine HCI 12.5mg / Guaifenesin 200mg. I am looking for some guidance here, and I know I do not use drugs and I also need to be working.... ## On the cheaper, less reliable drug tests, it seems as though anything is likely to show up, no matter what you took. I was researching ways in which you may be able to dispute a false positive and I came up on the following information: "Specific testing, such as that done b... ...

In addition, I take oral meds that may trip me, as antibiotics for the MRSA. , trileptal and percoset. thanks for help ## Almost all medications, whether ingested or topical, that have the caine at the end are distance cousins to Cocaine and with regular, heavy use they may cause a false positive for it on a drug test.
