Can Lidocaine Cause A Positive Drug Test (Page 2)

Updated

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.

I don't care if your a pathologist and your "opinion" is what is published and proven. You are and will be disproven in the future on your comments, (in caps!).
Many Americans are losing their lively hoods over you and your co-professional opinions and gathering from your strong sentiment, prejudice!

You could not be more wrong. It actually DOES depend on what specific test you have performed on the urine. Is it a quick, in the office test? If so, which type? Which manufacturer? You can demand a second sample using a different test, if available in the office. This is typically for DOT physicals, Counseling ordered by probation/parole, or even CVS brand 's name brand..." said with a sarcastic tone"
Anyway...I have seen topical as well as injectable analgesics throw a false positive on these types of tests. I have seen one positive, then the second sample in the office negative. The lab confirmed it was negative. Anyway...medications can interfere... The person at the lab can make a mistake. Maybe they didn't calibrate the machine properly.... If you haven't done cocaine, it shouldn't come up positive when confirmed correctly by the lab. If you DID cocaine, if you were drinking at the time, and you had some good s***, it can stay in your system a LONG time. Up to 20 says. If you are clean, like I said, send it to confirm. You can challenge it & have it sent to the lab, if it isn't already protocol.

Sorry Mr or Ms lab tech. Some people's bodies metabolize substances different than others. This could happen a lot more than you realize. Except how many people get drug tested soon after a dental procedure. Wait until it happens to someone with the money and power to have a legit medical study done on this. This has happened to me three times. But I get told if it's not in a medical journal than its not true.

You are full of BS! Educated beyond your intelligence? Just because you went to College does not mean that you are a Genius! It is related to Cocaine? Does that mean anything? That's right, Drug testers never make mistakes? How often do you calibrate your testing equipment? What if I had Lidocaine on my hands and it mixed with urine? Do they leave samples outside of the Office in BS lock box? Would that not break the chain of custody? I worked in labs and saw what some *****s working there did? It just depends on Humans as much as machines getting it right?

I'd like to know about hemp, hemp seeds and hemp oils. Nowadays when a MRO sees a red flag they simply go with it. My wife tested positive for THC. She had begun a hemp concentration diet from the seeds to the oils. She was called into work and was given a random drug test and five days later was told by the MRO that she tested positive for THC. She enrolled in a SAP with a professional SAP as her counselor. She went in and was tested and the test proved that she was negative for all including THC. Then the SAP recommended a 10hr mandatory program because of her profession. After further information, study and review from pharmacist and nutritionists we've come to find out that " Hemp " is a mutual family member of the Cannabis (Cannabidiol) Sativa family THC (Marijuana). The hemp doesn't promote that " psychoactive " high but it still has " THC " present in it. Given that " Marijuana / THC " in research are one in the same by way of the stalks growth. Is it possible to scientifically say that the metabolization is going to be the same and no different whether ingested as nutrients or smoked cause either and both ways it's in the body? It's said that in the environment of marijuana smoke one would really need to inhale lots of smoke to acquire a high level of or levels of THC and that has never been actually tested nor proven at least i cant locate it for trail report. So given that my wife ingested this Hemp Oil. 1200 - 2000 mg Consumed it by drinking it. We have the bottles and receipt of sale but employer is fighting against her. The Courier which performed the random test didn't offer legally the privilege to inform the MRO of substances which she had been consuming by way of the form which ask such questions and I feel that if she was able to inform them of such before testing we wouldn't be going in this direction legally.

So because I cut my hand open at work and I was given a shot to numb it before getting stitches I could and would test positive for cocaine if I tested in the next 2 days in a urine test?

This is quite sometime after this original post but I must refute these claims by Lab Tech. First and foremost, I have never done any type of illicit drug. I have not so much as drank a beer in my life. I am a family medicine doctor working in the oil industry in Alaska. On Jan 5 2017 I had a Lap Band removed after 10yrs. I flew to Tijuana Mexico on Jan 4 and returned on Jan 6 without incidence. On Jan 13 2017 I went in for my Hair Follicle drug test. Today Jan 19 2017 I was told I tested positive for Cocaine. Once again I have never done any illicit drugs nor am I on any Rx Drugs now or in the past. I am a vegan and eat a lot of herbs such as tumeric, ginger, moringa, cinnamon, hemp seed, flax seed. But I also had a Hair Follicle test done July 13 2016 and was ingesting the same herbs. So I just wanted to let people know that it is possible and you should fight if you know like I do that it couldnt be correct.

You need more schooling and lots more education there is 160 items that a person can use on daily basis that will show false positives ie: eat a poppy seed bagel 1 time daily then take urine test eat certain types of ice cream you are not very educated for being tech that is prob labs hiring tecks to run faulty tests labs continuing to investigate and violiate people on faulty tests these tests are so faulty most people have very easily law suit if u can find laywer because if u have tested positive and certain no drug use have hair follicle test done at own expense then Sue their ass off only way to stop these faulty tests!!!

Hair strand tests are also producing false positives. Not only was I prescribed a numbing cream but due to toothache was taking a high strength benzocaine, and local anesthetic. Let me tell each of you this: their should be a government warning about how it could test positive for cocaine. These mixed with any form of high strength meds can not be good. As for the i**** of 20 years, don't be so bloody arrogant. Science is science and you cannot mix anything with everything. People on here are telling you that they do not use cocaine and your basically calling us all liars you arrogant sod. How dare you, with your OUTDATED VIEWS and opinions. I don't take cocaine, so obviously this is the reason why.

I recently had a test come up positive at the emergency room for amphetamines, when all I had taken was viscous lidocaine. Things such as lidocaine, benzocaine and bupivocaine can cause a positive result for amphetamines, but the only thing that causes a positive cocaine result is actually cocaine.

You could not have a positive urine test for amphetamines with Lidocaine. It has no amphetamine in it... On the other hand testing positive for cocaine is more of a possibility.

You're FULL OF S***!!! There are certainly many different ways for Lidocaine and the same benzene ring to cause a positive test for this broad acting benzene ring out the outer edge of a molecule to get magnetic and say, YEP GUILTY GUILTY GUILTY, lets string him up... hang him HIGH!

It just happened to me. I use a lot of topical ointment that had lidocaine and dental meds & I tested positive for cocaine. My pain clinic has let me go because of it. I'm 60 yrs old and take apap/hydrocodone 325-10.

That is a blatant lie, I personally had to take a drug test today and it showed positive for cocaine. I also just had a procedure at the hospital this morning where lidocaine was used to numb the area where the dr. had to cut me. I also use lidocaine on my back and knee on a daily basis. I do not use cocaine so I know for a certain that lidocaine does cause false positive results in a drug screen. Most people are taking the screen for work or probation etc. I on the other hand had to take one to get custody of my grandson who was taken by cps falsely because my daughter had a seizure and blacked out with him home. This whole situation has been a nightmare. One fup to the next but as a society we rely so heavily upon imperfect systems and people. There is always room for error due to the fact that Adam dropped us all!!!!
