Norephedrine or ephedrine as amphetamines?

[aussiebound]

Would either of these run the risk of testing positive for amphetamines on a drug test? I know both ephedrine and norephedrine are both derivatives of speed. Sorry for the multiple questions about drug testing but better safe then sorry.

it should not cause a false positive...

this has been independently confirmed by three individuals taking tests for life and/or health insurance recently.

I've been drug-tested after taking Ephedrine and feared the same and was anticipating having to show my bottle of Ripped Fuel and blisters of Bronk-Aid. But nothing showed up so it does not come up as amphetamine. Meth-Amphetamine is synthesized from ephedrine and that is why in USA they added guafanessin (an expectorant) to ephedrine to hinder the synthesization by illegal meth labs. But there must be some alkaloid in the amphatamine that is not in Ephedra/ephedrine. So when they test for amph, eph should not trigger a positive. That is MY experience.
