Can you fail a drug test because of using ephedrine?

Answer 1

Absolutely! Ephedrine and it's cousin pseudoephedrine show as false positives for amphetimines in urine, sweat and hair test. However in multi-panel test such as a saliva test when the authority is testing for both amphetimine AND methamphetimine it will show as meth since is is a primary drug for making meth. It will show up as positive EVERYTIME so be careful! If you are taking a test that only test for amphetimines it will show up as positive there. Not all drug test are equal. Some only test for a broad category as amphetimines. Others separate between amphetiminies and methamphetimines.

Answer 2

Yes. All variations of methamphetamine, amphetamine, methcathinone and ephedrine have very similar molecular structures, and they all break down to the same compound in your body. In fact, ephedrine is a necessary precursor in synthesizing the other three drugs.

Urine tests, especially portable on-the-spot ones, are designed to detect this compound that these drugs break down into, not the drugs themselves, so whether you are on methamphetamine, amphetamine, methcathinone, or ephedrine or even pseudo ephedrine, you can test positive for amphetamines.

If you do test positive and you know you were only on ephedrine or pseudoephedrine, you can request a re-test that involves a proper lab using blood or hair samples.

Answer 3

Ephedra may give a false positive for Cocaine or Methamphetamine.

Answer 4

If the test is looking for stimulant and ephedrin metabolites, it might get positive for that point.

Answer 5

No, phenylephrine will not make you fail a drug test. Only the drugs that the company is testing for can make you fail the drug test.

Answer 6

No
