I found out last night.
I've been informed that you would really need to consume some serious amounts for a false positive.
though I had taken garden variety ephedra
Ephedrine HCL is more potent/pure so I'm not 100%

when I said I found out I meant I really took a test
part of a court appointed program
remember that 140 in a 70?

The credited response would be "no".
This would be using the (probably) safe assumption that the standard 5-panel drug screen used by employers is used. However, pseudoephedrine/ephedrine CAN show up as a false positive in some drug tests. Thing is, them sciency drug test-inventing people know this, since they're smart and stuff, and a 8.3 billion dollar lawsuit against them from the makers of this common OTC medicine would probably turn their company's funding into a really big number with a minus sign in front of it. If a false positive were to come up, just politely dispute it and inform them of using pseudoephedrine concurrent to the time at which the drug test was administered. They will then send it away for a more detailed assay and confirm the presence of pseudoephedrine and no trace of methamphetamine.
OTC medicines are a big business, their political pull notwithstanding. The sheer number of drugs they produce (... and that are consumed by people) would logically imply that them sciency drug test-inventing people would take this into account and create some form of safeguard, as re-testing hundreds of thousands of false positives would surely put the fear of god into them. That, and a very extremely super pissed-off CEO that might not like the idea of forking over a couple million dollars for a likely class-action suit against him by the moderately annoyed CEOs of the companies using their drug-testing products and services which caused their employees some slight disconcern when thousands of them were suddenly in fear of loosing their jobs for something they didn't do.

Medications & Substances Causing False Positives
According to a report by the Los Angeles Times New Service, a study of 161 prescription and over the counter medications showed that 65 of them produced false positive results in the most widely administered urine test. Ronald Siegel, a psychopharmacologist at UCLA said 'The widespread testing and reliance on tell-tale traces of drugs in the urine is simply a panic reaction invoked because the normal techniques for controlling drug use haven't worked very well. The next epidemic will be testing abuse."
Byrd Labs has in its possession an internal document from the Syva Company, makers of the widely used EMIT test. This document, leaked by a disillusioned company employee, lists more than 250 over-the-counter medications and prescription drugs that can cause false positives.

Antibiotics Cause False Positives on Heroin Test
Tuesday December 25 5:15 PM ET
By Emma Hitt, PhD
NEW YORK (Reuters Health) - Athletes and hopeful job applicants often hinge their careers on a clean drug test, but the use of certain antibiotics may cause an unsuspecting person to test positive for heroin even though they've never touched the drug, according to study findings released Tuesday.
Researchers led by Dr. Lindsey R. Baden of Harvard Medical School in Boston, Massachusetts, investigated this problem after they came across a patient in their practice who tested positive for opiates, and who was also taking an antibiotic called levofloxacin. The patient was nearly kicked out from a drug treatment center because of the result, which later proved to be false.
Opiates are a class of drugs that include the illegal drug heroin, and several other controlled drugs such as methadone, morphine, Demerol and codeine.
In their study, Baden and colleagues tested 13 different types of antibiotics, including levofloxacin and Cipro, all belonging to a class of chemicals called quinolones, to see what effect they would have on commercial opiate tests.
The researchers diluted the antibiotics to concentrations that would be expected to occur in urine and then tested the antibiotic samples using five different commercial tests to see if they would cause a positive result for opiates.
Two antibiotics, levofloxacin and ofloxacin, caused a strong positive result on four of the five tests.
Most of the other antibiotics also caused a positive result on at least two or three of the five tests. For example, Cipro, the drug given to thousands of people to fight possible anthrax exposure, resulted in a positive test in one out of the five tests.
To confirm these results in people, they had six people take a standard dose of one of the two antibiotics and collected their urine samples every 6 hours for the next 48 hours.
On one of the five tests, all three patients taking levofloxacin tested falsely positive within 2 hours and up to 22 hours after taking the drug. The results were similar in patients taking ofloxacin, the investigators report in the December 26th issue of The Journal of the American Medical Association.
Baden told Reuters Health that he suspects that the false positives result from the similar three-dimensional structures of opiates and the antibiotics. He also pointed out that other types of chemicals could cause a similar reaction.
According to Baden, it is possible that people have suffered consequences of a false positive test, because ``a positive drug test is often assumed true, while the protestations of the person being tested are looked at as self-serving.''
Baden recommends that anyone who tests falsely positive for opiates ask to have drug testing performed to confirm the result.
