Do detox drinks work to pass a oxycodone urine test?

Answer 1

I'm aware of one clinical study that tested this, and the conclusion was a very guarded "yes" ... in some (though not all) cases, drinking a gallon of various "detox" drinks, such as herbal tea, could reduce the drug metabolite concentration and cause a false negative (note: the study was specifically looking at marijuana and cocaine, but the principle is the same).

Before you start stocking up on the detox drinks, though, the study also found that plain water was nearly as effective as the tea. It's also a fine line you're walking; you have to drink enough (of whatever) to dilute the metabolites that shouldn't be there, but not so much that you bring the things that SHOULD be there, like urea and creatinine, down below their normal ranges, or the lab doing the test will suspect that you've adulterated the sample.
