false positive drug test trazodone for marijuana
3 Replies RSS Share
I tested positive for marijuana. I haven't taken any in 2 months but I do take trazodone. ## Is trazodone the problem? ## How could I test positive at the dr office for marijuana if i never used it in my life or been near anyone who did? No poppy seed bagels, no antibiotics. I am just prescribed steroids and Lupus meds, and monthly infusion for my Lupus. I was so very embarrassed when they told me my urine test results! I asked to be retested as was told no, which seemed strange. I went to my family dr the next day who agreed to send me to the lab for a urine test, as i told her i never did drugs/marijuana in my life except what was prescribed: Roxicodone, steroids, Lupus meds, heart arrhythmia med, and Aleve for inflammation from Lupus. I'm still waiting for results, but the fa... ...

False Positive On Drug Test For Thc
1 Reply RSS Share
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
32 Replies RSS Share
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'm on Klonopin and Ranitidine and I keep failing for THC on my t... ...

False Positive Drug Test
6 Replies RSS Share
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... ...

false positive on drug test for suboxone

I am having the same problem. My drug of choice was synthetic marijuana but I keep getting false-positives for suboxone. I have never in my life taken heroin or suboxone. I was kicked out of substance abuse treatment because of it. This is f***ed up. Example: On 7/10/2015, I gave a urine sample to my new treatment center as well a urine sample to my primary doctor. Treatment center result was positive for suboxone and the doctors result was clean thru and thru. ## Are there any drugs prescribed or otc that can cause a positive for subutex ## Froggie, Yes there are but you will need to google it. Even if you believe this to be true Unless the said specimen was tested via an extremely sensitive lab. ie; GC/MS your fighting an up hill battle. ## AlwaysAwork thanks for your reply would you ... ...

I tested positive for MDMA. I had recently smoked synthetic marijuana. Bizzaro to be specific. Is there anything in this that would cause this false positive? ## what substances, Legal or illicit, can bring up a falsley positve drug tst for mdma? ## I have not taken MDMA in TEN years.

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.

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... ...

Failed disa urine screen for marijuana, went threw the substance abuse program, waited 40 days and took another urine screen to return to work, but still have marijuana in my test results. So my question is will they make me take the substance abuse program again because it takes so long for marijuana to clear my system? ## My boyfriend took a hair follicle test with disa and failed but he does not smoke marijuana. Is there any chance for it to come back a false positive? What can we do to fix this? ## Not really anything you can do. They should have given him a number to call to return to 'active duty'. When he calls this number they will tell him where he can speak to a local drug counselor. He will have to visit that counselor for a consultation, they will then direct him to ... ...

Should I request another test?
