Can Adderall give a false positive test for Methamphetamine and not for Amphetamines?

This has happened to me twice now. I have never touched methamphetamine, but am prescribed generic adderall or d-amphetamine salt combo. I need to find references as to where I can prove that this is common in a urinalysis test.

Yes, Adderall has been known to cause a false positive for Methamphetamines on drug tests and it is actually noted in the PDR drug reference information for physicians.

Since Amphetamines and Methamphetamine are distantly related, it really isn't too surprising that this could occur.

Has this happened to you?

I take adderall for a medical reason known as narcolepsy. I am NOT a pill popper or a tweaker. You make people look bad. Not everyone takes medicine to get high

About 5 years ago I took a 5 panel drug test for a job. I gave them my prescriptions, one which was Adderall XR. I tested positive for meth. It is your right that you can contact another company to do a gc/ ms test on the same sample. I think the original company has to keep the sample for maybe a year. You have to pay out of pocket, probably btw. 100 and 200 dollars. If it comes back clear, the employer will probably reimburse you. When I called the original company to have them send it out to the gcms testing company, they said, "oh, that never happens with addrall and methamphetamine. In the years I've been doing this I've never seen it come out differently using gcms. Are you sure somebody couldn't have slipped you something?" Well, I had it done, and it came back fine, no methamphetamine, and I got a refund and the job.

Can you test positive for meth and not have amphetamine in your system.

If you were taking Sandoz/Eon generic the cause is a "bioequivalent" ingredient they use. No other generic will cause this. Unfortunately it isn't really a "false positive" it is positive because of what they put in that particular brand. No one in authority has yet tied in the Sandoz/Eon brand only so they aren't looking in the correct place.

Yes it can. It happened to me. Which resulted in cps removing my 2 children from my home for a month while they called my Dr. and checked medical records. I throw away my empty bottles after scratching the labels off I also made the mistake of shredding the papers that I get with my prescription. So no proof of a prescription for adderall on hand they really will mistake you for a meth user.. just make sure you have a pill bottle or something with your name on it to prove its not meth. It's best just tell them befor hand even if the prescription was not yours cause if u hide the fact that you took the pills they will definatly think u are a methhead.

CPS has too much power. What you need to do is run an ad on CPS involved grandparents and parents and file a CLASS ACTION law suit against them. They have to justify their jobs. So we have to be smarter and more aggressive with them. DO NOT ALLOW THEM IN YOUR HOME EVER! Let them get a court order. But we all have to stick together otherwise you will suffer without any support. And so will the children. They will be abused sexually, verbally, and mentally from some of these SO called foster parents that are only looking for money.

Some of the "screening " tests done in the doctors office will give a positive result for methamphetamines when the patient is taking Adderal which is amphetamine. Further testing by a more sophisticated test system in a toxicology laboratory can seperate these two and determine whether methamphetamine was actually present or if the signal was a false positive due to cross reactivity with amphetamine. Physicians Desk Reference under adderall indicates possibility of cross reactivity

While it is true that methamphetamines break down into amphetamines in your system, methamphetamines contain an extra CH3 molecule or methyl group, that makes it more potent. They are part of the same drug classification, however, they are NOT the same drug. It's like comparing morphine (semi synthetic) to heroin (completely synthetic).

A routine way to address this issue is to have the provider of the drug test contact your pharmacy.....I take this medication and the situation was cleared promptly.

The same exact thing happened to me when I was pregnant and on probation. I had severe heartburn during the last 4 months of my pregnancy. I started taking the OTC medication Ranitidine (Generic for Xantac). My probation officer, who by the way happened to be a wonderful woman, who helped change my life, needed me to do a drug screen. I said sure, we both went into the bathroom and I gave her the sample. She then said your urine is positive for meth, so I said of course, not thinking anything about it because I am and have been on methadone(was addicted to the prescription painkiller dilaudid, after the doctor gave it to me for severe pain from Lyme disease) for the past 3 years now. She said no honey methamphetamine, I just froze. I started to cry I told her that I did not do it repeatedly . She told me to stay in the bathroom while she walked down the hallway . I then came looking for her . I heard her speaking with another male probation officer that worked there . She was asking him if he knew of any medications or foods that could cause a false positive for methamphetamine's, he told her that was so many different ones. I heard her tell him she knew that I didn't do it but she didn't know what to do with the test because the judge had ordered the test. She decided to tell the judge that she had forgotten about it and, she hid the test and sent the remainder of the sample out to the lab. I did some research while waiting for the test results from the laboratory I found that ranitidine a.k.a. generic Zantac frequently caused false-positive for methamphetamine. I was so relieved and happy that someone she had actually believed in me enough to hide a test and send it out to a laboratory to be checked. I finally felt I was gaining some trust back. I truly felt exonerated, that was two years ago. I've been sober for a little over three years now. If you know you didn't do something don't let them just tell you that that's it. There are other, more sophisticated tests that can be performed. That's your good name and reputation on the line.

I have to take random hair test and sometimes urine court ordered. I have taken adderall 30mg twice a day for years, my last hair test showed positive for amphetamine and methamphetamine, but i took a urine test about a month ago and it just showed positive for amphetamine. Would be great if i could get explanation on that.

Adderal "is" amphetamine so if the patient is taking Adderal , they should give a positive result for amphetamines. In addition since amphetamine (Adderal) is very similiar structurally to methamphetamine, with some test kits the amphetamine cross reacts and will cause a positive test result for methamphetamine. In this case since no actual amphetamine is present this is termed a false positive.

I would not expect to see a positive for methamphetamine due to amphetamine cross reactivity along with a negative amphetamine test.

If you have a prescription for Adderal you usually will show a positive result for amphetamine. This should be o.k. since it's a legal prescription. In addition high levels of amphetamine can cause a positive reading for the methamphetamine assay also even though no actual methamphetamine is present. Unless further testing is conducted by a different testing method (typicall a test called "Gas chromatography /mass spec") they cannot tell if you have ingested methamphetaminen or not..

the reason you tested positive for meth is because meth breaks down into amphetamine when introduced into the body. the meth molecule just allows the amphetamine to pass through the blood brain barrier quicker, so if you inject it or smoke it you get a rush, otherwise, meth and adderall are essentially the same thing

Nope, because of the bioavailability of these drugs, some unchanged amphetamine (Adderall) and some unchanged methamphetamine (meth) would be passed through the urine, and since there isn't any methamphetamine in Adderall, they would know you weren't on meth.

Where does it note this in the PDR exactly? We are having this issue with DHR and my partner who takes adderall. I need to show them it's possible.
