Ephedrine, although chemically very similar to the amphetamines, should not show up on a drug screen as amphetamine. Although, ephedrine can be tested for on a drug screen separately (usually specifically requested).

∙ 13y agoNo. Drug tests work by testing for certain chemicals that are found in drugs. The chemical "Methamphetamine" has nothing to do with chemical "Ephedrine" so will not show up on a drug test.

When consumed with caffeine and aspirin they can show up in drug test for upto a day
Wiki User
∙ 13y agoYes it can. Ephedrine is one of the main ingredients in Meth Amphetamine and can deffinitley cause a positive UA for Meth.
Wiki User

In my experience you can fail for amphetamines after taking sudafed. Sudafed contains pseudo-ephedrine, an ingredient in the manufacture of meth-amphetamine. You need at least 72 ours to get pseudo-ephedrine out of your system.
P and Meth are two of them.
No, it does not. Some of the cold medications containing ephedrine or pseudo-ephedrine may show up in some of the cheaper tests for meth-amphetamine because they are precursors to meth-amphetamine. However if the test is done in a lab meth would quickly be ruled out.
No, they are not. Marijuana contains THC, Crystal Meth contains Ephedrine.

it is impossible to fail for meth unless you are using the drug. Even if a few crystals were transfered in saliva it would still not be enough to show up. So there are one of two reasons. 1.) you are using meth. 2.) you are taking cold medicine or some other psyeudoephedrine/ephedrine containing medication. There are medications that have this chemical, but it does not make you high as meth does. Ephedrine is synthesized into meth, therefore it is the substance a drug test will test for.
Ephedrine HCL or pseudoephedrine HCL, two alkaloids found in ephedra, can be used in making meth.
It won't if you wait 2 more days.
Methamphetamine was first synthesized from ephedrine in Japan, in 1894.
