Yes. However, ephedrine is not commonly tested for. If it is tested for depends on if it is a banned substance for whatever reason you are being drug tested. The International Olympic Committee bans ephedrine use after a certain threshold for example. Ephedrine is not an illegal drug outside of most competitions.
Not if the test is for ephedrine.
Ephedrine can show a false positive for amphetamines on a drug test.
A drug test won't be able to tell which brand the drug is, just that the drug is present, and how much of it.
The short answer is yes. For approximately five to seven days.
yes. labritory tests are very prescise.
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).
sudafed. anything with high levels of ephedrine in it
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.
Can you tell the difference between Vyvanse and Concerta in a drug test
No, a drug test will give results for drug use in the present.
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.
No.
