Can taking psuedephedrine show up as meth in a drug test?

Can taking psuedephedrine show up as meth in a drug test?

Yes, but only in: Screening tests, not in confirmatory tests. It does not show up as methamphetamine but rather as amphetamine itself. Confirmatory tests (gas chromatography, mass spectroscopy and others) can definitively determine whether there is methamphetamine or amphetamine and differentiate it from pseudoephedrine, but the screening tests cannot. ...Read more

How long will meth stay in your system with a urine drug test?

10 days or less: For most individuals having used the substance, the general consensus is often noted as a maximum of 10 days that methamphetamine remains detectable via a urine drug test. Often it is more like 3-5 days. The urine test rarely gives an incorrect finding if meth is in there. It can be detected in hair for much much longer.

Does tri adalean diet pills show up as meth on a drug test?

Does tri adalean diet pills show up as meth on a drug test?

Possibly: Triadalean contains multiple stimulants including various phenylethylamines, theobromine, caffeine, and guarana. Some of these could show up as initial false positives for amphetamines, but more focused testing would be done. Triadalean has strong potential to cause jitteriness and anxiety, with little support for effectiveness in weight loss. ...Read more

Hello doctors, can Ultram show up as meth on a drug test?

Hello doctors, can Ultram show up as meth on a drug test?

No: There are no reports of any such false positives with tramadol to my knowledge, or in the literature. I checked several authoritative sites and cannot find any references to this. I found that on drug bulletin boards, many people (all anonymous, ? authority) say that it does show up as methadone. It definitely does not cause false positive for methamphetamine. Meth can mean either. ...Read more

How does a home drug test detect drugs in your urine such as meth and why do some prescription drugs test positive?

How does a home drug test detect drugs in your urine such as meth and why do some prescription drugs test positive?

Drug tests: Drug tests are used as much to determine what the person has not taken as to what the person has taken. Drug tests may look for illegal drugs. More often they test patients to make sure that they are taking their medications. Sometimes patients sell their medications or feel that they do not need the medication and stop taking it. Drug tests are used for these purposes. ...Read more

Currently taking Vyvanse (lisdexamfetamine) and since it has amphetamines in it, I am concerned I would come out as positive for meth in a drug test. Is this possible?

It is possible: Vyvanse (lisdexamfetamine) vs. Meth. Vyvanse (lisdexamfetamine) is dextroamphetamine. Methamphetamine has the extra Methyl and is a strong oxidant with organic chemicals. A positive drug test in your case should not affect you as long as you disclose the Vyvanse (lisdexamfetamine) intake as your current medication. ...Read more

Been taking pseudophedrine HCl 60mg every 4-6 hrs for past 3 days due the flu. I have to take a drug test on monday. Will I test positive for meth?

Been taking pseudophedrine HCl 60mg every 4-6 hrs for past 3 days due the flu. I have to take a drug test on monday. Will I test positive for meth?

No: If drug tests are properly done, the initial test is a screening test, which then must be confirmed with more complex and sophisticated testing. Screening tests may show positive for amphetamine with use of sudafed and other decongestants, but the confirmatory tests will not be positive. If whoever is doing the test does not do confirmatory testing, you should seek your legal options if positive. ...Read more

Could I come out positive for meth if they swab my hand for an ion drug test?

Could I come out positive for meth if they swab my hand for an ion drug test?

Sure: An ION drug test is a screening test. Like any kind of test, anybody's result can be positive or be negative. A person who tests positive is a true positive if she has the substance, but is a false positive if she has none of the substance. The technology can be helpful in other settings, such as screening passengers and cargo at airports for drugs and explosives. ...Read more

Hi, I just took a hair follicle drug test for pre-employment it came up positive for both amphetimine and meth 1053 pgmg but ive been clean for a year?

Do you have very: Long hair? While hair follicle tests enjoy a mixed reputation, when they do work accurately, its hard to refute to a potential employer. Most people take other tests that are shorter-acting (urine, blood), which is what you might ask your pre-employer to accept as proof that you are clear. ...Read more

What are some medicine that might come out positive as meth on a drug test medicine I take prometh/codeine, prednisone, advair, hydroxzine. False positive for meth

None of the above: There are many false positives for all amphetamines, but not specifically methamphetamine. Proper drug testing goes beyond the screening test - if that is positive definitive testing should be done, which will eliminate essentially all false positives. Every cold medication around can give a positive amphetamine, but not a positive for methamphetamine. You need to demand the definitive test. ...Read more

What DO you take?: Someone else's specimen may have been mislabeled as yours. Or, you may be taking a medication that is "cross-reactive" with amphetamines and caused a false-positive result. Labs usually include such cautionary information in their reports. Go over the lab report and your meds with the ordering physician. ...Read more
