I have to prove my innocense
Hello- I was recently taken to the ER due to a seizure,( Which at the time I had not been diagnosed with seizures yet). They urine screened me and VERY much to my surprise it came back with a positive for PCP. Keep in mind, all my vitals, behaviors, pupils, ect. were just fine and normal. I was there 5 hours, they waited until the last 30 minutes that I was there to drug test me. I Asked for a 2nd drug screen, the nurse told me that would be "useless and my insurance would not pay for and nobody would see it". I refused to sign the paperwork. I lost my children over this drug screen. The nurse also failed to note that I had Ambien, Clonidine, hydroxizine, sudafed, alka-seltzer cold, B-12 shot the day before, women's multi-vitaman, and a iron vitamin in my system. I had the flu. I have been told by many that many of these would be the cause of a false positive. I've never done a drug in my life, but sadly it's me that has to prove this in court to get my children back Thursday..Any help would sure be appreciated.
AskDocWeb: Please see the link for "What to do if CPS workers are investigating you" on page 169. There is some good advice there.
The list of substances that might show up as PCP on urine drug screens is pretty short:
K2 synthetic marijuana
I recently was drug tested for k2 synthetic marijuana and tested positive. I don't smoke it nor am I ever around it. They are sending it to the lab. Is there anything I could have taken to test positive?
AskDocWeb: Sorry Alisa, our database contains no listing for anything that might cause a false positive for k2.
False positive for cocaine
I had a false positive for cocaine. i take lamictal, serequel, temazapam, clonepin, viibryd, a nightmare med that begins with the letter p (not at home)and soma. can you help?
AskDocWeb: There are only a few substances that have shown up as a false positive for cocaine on urine drug screens: Amoxicillin, Ampicillin, bupivacaine, Cola products (tea, flour, oil), and tonic water. However both kidney disease and diabetes have been identified as possible causes of false positives for cocaine. If you get a GC/MS confirmation test, that should eliminate any false positives.
My brother is in prison they gave him a drug test he has never taken drugs he failed the test for meth. We do not understand how it could show this up he takes mobic for his back he takes an allergy pill antihistamin and he was on amocicillim antiobiotic for 10 days and something for heartburns could these meds. cause a false reading for meth and what can he do they gave him a d.r. and he has to go to a hearing in a couple of weeks is there anyone we can call at prison?
AskDocWeb: As a general rule, whenever there are legal consequences for drug testing, any positive urine test result should be confirmed by GC/MS testing. You might call the general number for the prison and they may be able to tell you which department to talk to for specific information. The title of the person in charge of drug testing varies from state to state. State law also varies so you may want to ask a Lawyer about your particular situation. Some state prison systems do not have a standard drug-testing policy (such as Louisiana).
If you do any nasel. Or over the counter allergy mess like clairatin. You will get a false posstive. That I know been doing research about this in school. And got a A plus. For this that the sh*t or what.
AskDocWeb: You might want to ask your teacher for help with spelling and grammar because those areas need improvement.
False positive for benzodiazepine
I went in to see my counsler and she did a urine dip stick drug screen on me and i was positive for Benzodiazipine s and i have not touched them in over a year and a half. I am on Prozac, Trazodone, Remrom and Inderol and have taken Midol, IBUprofen, tylenol and caffeine. Can ANY of this AT ALL cause a false positive drug test cause i can go to jail for a year and a half if i dont settle this please help me!!!
AskDocWeb: None of your meds are known to cause a false positive for benzodiazepine but that doesn't rule out the possibility of one. For that you would need to get a confirmation test on the original sample. If a SAMHSA certified laboratory can't confirm the presents of benzodiazepine then you are off the hook. For a list of SAMHSA certified laboratories see page 185.
When the cop was looking
I got arrested by police and did I mouth swab drug test for them they use a cozart machine when the cop was looking the othet way I tipped water on the mouth swab to try n pass the test I tested possative for cocaine m heroin stillmthough the swab never went in my mouth at all when he said possative I said impossable the police sent my sample to a lab for further testin surley it will come back negative cos my saliver wasn't used just water off some wet tissue how can they read possative do u think they don't clean machine after every test I can't figure how it can be. Possative
AskDocWeb: Putting water on the swab when the cop wasn't looking indicates that you likely had something illegal in your system. Maybe you missed the note above that says this forum is for those who do NOT abuse drugs.

I am a patient/client at a methadone clinic. I take lexapro, melatonin, migraine relief (aspirin, acetaminophen & caffeine) on a daily basis. Would any of these drugs show up for a false positive drug screen that i have to take in order to stay in the methadone treatment?
AskDocWeb: None of those by themselves have been reported to show up as a false positive on drug screens. However when acetaminophen is combined with codeine as in Paracetamol, that may show up (Reference 33).
I had to recently take a drug screen for my meds at my doctor. I am taking methadone hydroco
