With the ever increasingly large number of false positive reports I've seen, I certainly wouldn't be surprised if any one of those medications came up positive for cocaine; and I mean that seriously. On the cheaper, less reliable tests, it seems anything is possible.

Now there is specific testing, such as that done by a gas chromatograph mass spectrometer, which has the ability to distinguish the exact substance in question. This type of testing is not initially performed because of cost, but, is often a follow-up option for those facing serious consequences such as a job loss, jail time, etc. This may be something you'd want to look into.

If you're able to I would also ask your doctor if additional testing may be done on the original sample so that a second sample may be taken. Unfortunately, the outcome of it may be different or similar due their inconsistency; but a different outcome would really show how terrible their accuracy is.

I hope this helps!

I have taken a mouthswab test and it came back positive for buprenorphine. I have not taken anything of the sort, I actually had to ask my P.O. what it was and he really didn't know. I take Cymbalta and Elavil for anti-depressants every day and some weight loss supplements. please help my reputation and life are on the line

I recently had a positive for Meth and a confirmed second test at the hospital I haven't used in nearly 2yrs and I'm being looked at like I'm lying which upsets me because I have no problem with being honest about my use. And I spent a long time in inpatient treatment and have been clean since release. I'm on numerous medications gabapentin lantus humulin N. Prednisone and hydrocodone and promethazine and clindamycin. Could it be possible for a positive from combination of tbese

I got serious mouth ulcers, used oral lidocaine and tested positive for cocaine on an oral mouth swab. I do take neurontin and ativan. Could this have caused the positive result?

gas chromatography doesn't 100% determine substance, actually it wont show the ingested substance, but what GC does is show the metabolites of said substance, and the doctor(if they are good) can tell which substance was taken.
