Can Lidocaine Test Positive For Cocaine

The police raided my frinds house got lidocaine claims it tested positive as cocaine in the lab is this possible cause they're looking ay 5 years in prison ## It is related to cocaine, but there is no way it should be detected as such in an actual lab test, since that type of testing would clearly be able to distinguish between the two. Are there any other questions or comments? ## I am taking a random ua for a dui and was told I tested pos. for coke. I called b.s. then remembered I had just had x-ray guided cortizone/steroid shots for my sciatica. I'm not sure what all they put in those shots but before that they used novicaine. I know for sure that is why I tested pos. I just don't know how to prove to the court that those shots were the reason for a false pos. The clinic ...

I have a small delivery/transportation business in Ohio. My husband & I decided to grow our company by purchasing a vehicle that requires a CDL B. The guy we have driving that truck has his class A but if he quit or needed a day off we had no one to fill in so I took classes to get my CDL A's in March of 2014. After receiving my CDL’s [for experience & financial reasons] I made the decision to sign on & drive for a large trucking company in June of 2014. The company performed a hair drug test on me but apparently did not get they're results until after I started the orientation. During my orientation the MRO called & tells me that I tested positive for cocaine. I knew that there had been a mistake because I am not a drug user. He asked me had I been to the ...

I have been getting lidocaine shots in my back every month for 4 yrs and lidocaine infusion. every 3 months would that show as cocaine on a drug stick test ## Hi J, Other than a few forum posts from different individuals, I haven't located any concrete details confirming the possibility of a false positive for Cocaine from Lidocaine. However, I do have reason to believe that it's still a strong possibility due to the faulty standard drug tests they use today. A lot of these standardized drug tests have a fairly high false-positive response, where it seems as though anything is likely to show up, no matter what you took. To my knowledge false positives are known to occur on them anywhere from 4 to 50% of the time. Have you asked your doctor yet about getting re-tested?

Is there any kind of food or meditation that can cause a false positive drug test for cocaine? ## I had a hair drug test that came up positive for cocaine. I'm dealing with an addiction specialist who says that I'm a heavy user of cocaine for the last 30 days. Intetesting that I have not used cocaine. I'm wondering if anyone has had a positive hair test for cocaine and did not use and what might have happened here. Given the reputation of this dr, I went for an independent test, who also told me there was no reason to go for an independent test that it would prove nothing. I went anyway. The only thing I've used is Lidoderm patches for my back. ## No, those patches will not give a false positive for cocaine.

I falsed a urine test with small trace of cocaine in it.

I went to court, and took a drug screen and I was tested positive for cocaine. The day before my doctor gave me a shot that had lidocaine in it. ## From what I could gather, Caine anesthetics seem to be notorious for causing false positives for cocaine. This includes Novocaine, Benzocaine, Lidocaine, etc. If you were to take any course of action, I would recommend insisting on additional testing & perhaps requesting a GC/MS test (Gas Chromatography / Mass Spectrometry), as it is considered to be the most definitive method for confirming the presence of a drug in the urine. I think it's down right unfair for companies to not use this type of testing right off the bat, since there are so many false-positives being reported on a daily basis. At this point in time though, the best a...

I tested positive for cocaine but use liquid lidocaine for mouth ulcers every 4-6 hours and have for months. ## I realize this question was posted a very long time ago but I wanted to let you know that viscous lidocaine, which is what you are referring to and I was recently prescribed, will not cause a positive result for cocaine. It does however sometimes cause a positive result for one of the amphetamine categories (I believe it was methamphetamines). According to poison control and to the lab that I spoke to the only thing that can cause a cocaine positive on a drug test is actually cocaine. Not lidocaine or novocaine or bupivacaine, etc. ## Wrong do more research. Lidocain does test false positive and the doctors know this but wont discuss it same as morphine they wont discuss it.

using lidocaine patch and test positive for cocaine ## Is lidocaine patch addictive? ## how long after a didoderm patch will i test positive for cocaine ## i test for cocaine every week with a saliva swab test, i use lidocaine for pain (patches). will a false positive show cocaine use if i use lidocaine long term? ## Can heavy use of 700 mg Lidocaine Patch Cause Negative Positive For Cocaine in a hair test? ## Can ora lidocaine show up as cocaine on urine drug screen? ## It is unlikely that the use of a lidocaine patch will show a false positive for cocaine. Just to be on the safe side, take your prescription for lidocaine to the testing site so they can make a notation on your test.

Went to the dentist and had a tooth pulled. Dentist gave lidocaine with something else. Had a positive urine test for amphetamines. Do these do this? Or amoxicillin?

i need to know if lidocaine viscous can show up as alcohol in a urine test. ## can lidocaine show up as cocaine on i urine test i got a friend that failed a drug test for cocaine but he said he dont do that he said he used lidocaine for a toothache i need to know asap ## On the alcohol question, no it should not show up as that, however, if you have a prescription for it, you should inform them of this, when you go in for testing. Which leads to pnut's question and yes, it can cause a false positive for Cocaine on some tests. It is distantly related to it. Since this works as an anesthetic, there can be severe problems associated with using it improperly and overdosing, so it shouldn't be used with a doctor's instructions and supervision.

I have severe neurapathy and use very strong topical ointment. It contains: Marcaine, Ketamine, Ketoprofan, Clonidine, Gabapentin, Lidocaine, Amitriptyline, and Lanacaine in patches. The severe pereprial neurapathy can develop dermal ulcers. Clearly some ointment that will enter the blood stream. In addition, I take oral meds that may trip me, as antibiotics for the MRSA. Trileptal and Percocet. Thanks for your help. ## Almost all medications, whether ingested or topical, that have the caine at the end are distance cousins to Cocaine and with regular, heavy use they may cause a false positive for it on a drug test. It is rare, since not a lot usually enters the blood stream when they are applied topically, but it has been known to happen. Do you use this by prescription or is it somethi...

I used a Lidocaine patch - can it make me come up positive for Morphine on a urine test? ## No, Lidocaine isn't listed as being known to cause a false positive for anything. Did this happen to you? High doses of it have been known to cause a false positive for Cocaine, since they are distantly related, but you usually don't absorb enough from the patch to have it be detected as anything. ## Well which is it? Lidocaine does not cause a false positive for anything... or High doses have been known to cause false positives for Cocaine? You are contradicting yourself and therefore not looking to credible to me. If Lidocaine has been known to cause a false positive for Cocaine, at any dosage, you should state that and leave it at that. ## I WAS TESTED POSTIVE FOR MORPHINE I NEVER HAVE...

UA positive for morphine offender claimed she had an epidural 4 days ago. ## The drugs commonly used in epidural anesthesia are bupivicaine (Marcaine, Sensorcaine); chloroprocaine (Nesacaine); and lidocaine (Xylocaine). Of those mentioned, my research tells me that Lidocaine can cause false positives, because it is distantly related to Cocaine. (but I haven't found information on the other drugs listed). On the cheaper, non-certified drug tests, false positives are known to occur anywhere from 4 to 50% of the time. There are actually quite a few discussion threads on this topic floating around the internet. I hope the information above helps! ## There are new epidurals that are morphine based. I had one on 3/26 when i had a csection. So yes, there are morphine based epidurals. I als...
