Drugs in your system last how long ?

That’s doubtless the mechanism.

Some assays do indeed test for the urine “detoxifying” agents. And a positive test for such an agent is considered the same as a positive test for a drug, from a job eligibility and reporting standpoint.

Lotsa things cause false positives, but if a test is positive for something, it ought to be confirmed by better and better assay techniques, until the chance of a false positive is very, very, very remote. Gas chromatography doesn’t leave much room for false positives, and mass spectrophotometry is the gold standard.

Wow if your using a spectrometer to analyze employee pee you certainly are a suspicious boss. (yep the ryhme was intentional.) :slight_smile:

So tell us who actually uses drug tests in the US ? I personally have never been submitted to one.

Have you ever tried working for a corporation? Nearly all test now. As do nearly all government jobs…
BTW, as far as LSD is concerned. I’ve heard that you can’t detect it in your system even when your tripping your ass off (just ignore the pupils as big as your head…) Think of a few micrograms dissolved in your whole body as undetectable.

Didn’t someone recently demonstrate how to fail a drug test simply by eating poppy seed bagels. Also I think Cecil had something to say about this also.
