False Positive On Drug Test For Thc
1 Reply RSS
I have been injected with steroids 3 times in the last four weeks, I am prescribed 70mg Vyvanse, and 1800 Ibuprofen daily and I have my first pee test on Tuesday with my PO and I am very scared that it will show thc. Is this true and would I still be in trouble even though my PO is well aware of what I am taking? ## Hi Michelle, I can certainly understand your concern for THC showing up on your drug test, since Ibuprofen is known to cause false positives for Marijuana (THC). In my opinion, your best bet would be to reference any articles of information stating that this is in fact a possibility that they should be made aware of. I would also bring copies of your prescription to the lab and even let your PO be made aware of this as well. I think a great resource for false positives is: a... ...

However, there are quite a few over the counter products that can, far too many for me to list them all, actually. What else were you taking? If you can post back with this information, I will gladly check for you. ## I don't parta... ...

Drug test false positive for THC
2 Replies RSS
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? ...

False Positive Drug Test
6 Replies RSS
I have taken numerous over the counter medicines for sinus headaches, allergies, and pain relivers containing ibuprofen in the last 6 months. I have to take a pre employment drug test soon. I fear some of these medicines might show up as an illegal drug in my hair follicle drug test. Do I need to worry about this? ## It really depends on what you've taken and the quality of the test that is done. False positives have become fairly common. Just as an example, on a poorly done test, the Ibuprofen could give a false positive for Marijuana. This happens much more frequently with urine tests, however, there is always a slight possibility that it could do the same on other tests, as well. There are also reports of many over the counter cold and allergy preparations causing false positives... ...

1 Reply RSS
I am on a pretrial contract and get drug tested every week. they do an eight panel, that tests for marijuana, amphetamine, methamphetamine, benzodiazephines, morphine / opiates, phencyclidine, and barbiturates. they also do a separate test for buprenorphine. I pass the eight panel test, but a faint line shows up on the buprenorphine test. I don't take any other medications nor do I use suboxone. what, besides other medications, would cause the false positive on the buprenorphine test?... I have done research, and it all says that other medications would do it. im not taking any, and nothing shows up on the eight panel.. is there anything such as food, drinks, hygine items, etc. that could cause this to happen? ## I am on the pretrial program as well. Ive found out that when i take a... ...

i am on at least 10 different medications ive done research and over half of them can cause positive or false positive for THC. my question is if one individually can cause this what happens with all five of them together and possibly the rest? the ones i know of so far are robaxin, naproxen, promethazine, voltaren gel, and the flector patch. the others i am uncertain of they are cymbalta, trazadone, seroquel, nexium, and magnesium. i have had multiple test come back positive and i do not use marijuana, i am trying to explore every avenue and get as much research and proof to support my case. any help will be greatly appreciated. ## If the military gave you Methocarbamol or any other meds dont worry its all on record. ## I know for a fact that promethazine can, as it just happened to me... ...

I just took a Hair follicle Drug. the test came back positive for marijuana, but it was the absolute lowest amount that can be detected.

Amphetamines False Positive Drug Test

I have somehow tested positive for amphetimine but the only drug that I touch Is marijuana. How is this possible? It was a urine test done in a hospital. ## If u take allergy pills that sometimes shows up as a false positive for amphetamines if u haven't then I don't know how it happened that's all I know ## It should occur from just marijuana. However, Dloc is correct, these false positives can be caused by other medications, even over the counter products. Did you take anything? ## Nope. Nothing. Not unless you count Tylenol. ## i have had a positive test result for amphetamine.i have never used the drug.the only thing i take is motillium for sickness which contains domperidone.can you help ## @nicole, If you or someone you know is facing serious consequences such as a job... ...
