Drug Test False Positive For Thc
Updated
Emerald Says:
I took a drug test for employment & an oral swab was used. I do not use any illicit drugs but I was contacted & told my test came up positive for THC. I do know some people who use marijuana but I understand that it is very rare for a test to come up positive for second-hand smoke, especially with an oral swab b/c it is hard for them to detect marijuana to begin with. I take Ibuprofen at night. Could this have caused it?

Ibuprofen has been known to cause a false positivr under certain circumstances. You need to ask to re-take it or to perform a more specific test on the previous sample.

It is very easy to detect THC? I did just read that iboproffin can even show a false positive for LSD of all things?

I took a pre-employment drug screen today and it showed positive for THC. I do not use any illegal drugs. I'm currently taking Levothyroxine, gabapentin, cyclobenzaprine, Women's Ultra Mega without Iron and Iodine, Beyond Raw Neuro Shed, Garcinia 4X SX-7 and (4) Ibuprofen 800mg daily. Will any of this cause a false positive?

I started a warehouse job, believing this was a blessing, but when my drug test came in I tested positive for marijuana; knowing I don't do any drugs period except what the Dr prescribed, which is naproxen and norco for pain. Now I have lost my job and have no proof. Someone please let me know something? It's crazy especially when you know you live a drug free life. I mean I don't know what to do at this point... Now I'm having to go through trying to clean my system from medications that a Dr prescribed.

I challenged my positive test. Knowing that I am drug free and would only take whatever is prescribed by my doctor. I went to a lab that does all types of drug test and paid for my own private test. The results came back negative as expected. I went to the company that terminated me and showed them the proof that the first test was wrong.

I quit marijuana 4 months ago. I was a heavy concentrate smoker for about 9 months. I have lost 130 pounds with no diet or exercise. I am tired all the time and have bad leg cramps. I don't take any meds at all except Advil for pain. I am still testing positive for THC and everyone thinks I'm still using, but I am not. My freedom is on the line. Could I have a kidney malfunction that is causing the test to show THC when I haven't had any in months?

After a false positive myself i researched the testing and 1 out of every 10k strip cups are defective,and 1 out of every 15k bottles of the reagent used in standard lab tests are defective.I've taken urine screens monthly since 2006& had 2 false positive results 1 for amphetamine which after insisting on electron spectography test which isolates every compound turns out that it was icyhot.to save $the strip test only needs 4 matching alkaloids to be positive,standard lab tests use 12 and the reagent shows positive.the tests aren't specific to each drug and requires only a small amount of the compounds that the drug makes once metabolized.I'd suggest looking for what compounds are required for the test to show positive and then compare to everything you take,if there is no matches the cups defective or you did it.I hope this helps jobs and not losing medications plus being labeled a drug using liar.

I’ve gone to the same Dr. for 18 years. I’m a chronic pain patient— 4 back surgeries, 2 neck surgeries and still have 2 herniated discs in my back. I’ve been on Fentanyl Patches for a year now. Two days ago the office called & said the Dr will not prescribe narcotics. This was because I tested positive for THC. Warning to others— watch out.

My husband is doing chemo for colon rectal cancer and he tested positive for marijuana. He doesn't do any kind of drugs. The MRO doctor said they don't recognize his medication. He was just coming off his pump when he did his urine test. Can't he request a new urine test? Any info would be great!

Re: Jessi (# 19) 
The more weight you have the more you’re going to show positive for THC because THC stores in your fat cells. If you were a heavy smoker it could take up to 40 days to get clean. Your drug screening should show a lesser amount each time you take the test and it should show that it’s leaving your system.
