I hope this was worth it...

So SWIM had developed a nice little oxycodone habit, snorting approximately 200mg a day for several months.

Much to his chagrin, he found out he had a drug test (with 2 weeks' notice). He quit cold turkey-- which was of course great fun-- you should try it. Anyway, to the question...

I know oxycodone eliminates hella fast, but for someone who's been ingesting huge quantities over extended periods of time, is two weeks still enough to clear one's urine? ...Comments? ...Thoughts? ...Bets?

SWIM's piss went off to the lab a few days ago, so he'll have the results soon. Man it'd suck if he quit cold turkey just to fail anyway.

For an idea of what SWIM's test probably includes, I should tell you that he works as a technician at a pain clinic. Six months and this is his first post-employment UA. Pretty good run, eh?

Anyway, discuss amongst yourselves! ...I need to put myself into a (legally prescribed) Xanax coma before all this terrible stress and sobriety gives me an ulcer.

oh yeah swim is pretty sure that swiy will piss clean. in some drug tests they don't even test for oxy as the standard opiate panel doesn't cover it. but like swim said, swiy will prolly be clean by then.

btw good luck with the habit, been there done that and it sucks.

LITTLE habit? 200mg a day is unfathomable to little swim who can barely swallow an 80! Two weeks should be plenty. A single week would be sufficient. Not sure what magnitude of use is, but generally 3-5 days is all it takes to get that shit out.

As far as what drugs are tested, even basic piss test test for "opiates" in general, and this would defintily include oxycodone. But synthetic opiates like suboxone (don't know the chem name) are not. Some tests have heroin specific pannels, but have other opiates right next to it.

really? swims drug tests when his mom was testing him(he was 16 at the time) tested for opiates but swims mom had to get one specifically for oxy. and swim read somewhere that basic opiate panels won't usually pick it up... thats just what he thought though. if swim is wrong, he apologizes for any misinformation.

Oxycodone will test positive for opiates. The reason there is a separate test for oxycodone is because the substance is eliminated from the body much sooner than most opiates.

The oxycodone test is set to detect at a lower ng level.

In addition the oxy test will also show positive for other opiates as well.

And being employed at a pain clinic, SWIM is pretty sure that he'll have individual tests performed for atypical narcotics like oxycodone, fentanyl, and so on (the ones that don't metabolize into morphine or codeine). So the question now is, how long would an oxycodone-specific test be able to detect it 2 weeks later?

K...What is 2 weeks? About 80 half-lives? So say combine the last week of usage into a single dose, 1,400mg all at once, just to be conservative (not to allow for elimination during intake)... divide by 2, 80 times... Correct? So the maximum oxy in the urine would be 1,400mg / 2^80 ?? SWIM's computer calculator won't do scientific notation. But he knows the typical cut-off is 50 - 100 nanograms. Can anyone with a graphing calculator provide him with a prognosis? Pleaseeeee?

K, 100 nanograms, the typical cutoff, is equal to 0.0001mg. All SWIM needs is someone to do the division mentioned above with a proper calculator... No, SWIM's not being lazy, he's tried all the half-life calculators on the net, but they're all crappy HTML-based affairs that only go so many decimal points out...

DrGonzo added 12 Minutes and 37 Seconds later...

Alright, sorry, this is my last post. Sorry to ramble. To avoid any unnecessary hangups, I just wanted to say SWIM knows that the half-life does not equal the amount of drug in one's urine... But SWIM's logic is, if the entire amount of oxycodone dissolved in SWIM's body tissue (as calculated by the above equation) is less than 100ng, there's no way he could fail the test.

The job has its perks. He don't wanna lose it!

Anyone with a graphing calc and the will to use it will have, um, good karma.

oh okay, swim is sorry for the misinformation. he feels like an ass, but hey at least he learned something new.

Oxycodone is a synthetic opiate and does indeed require a specific panel to be tested for. You could be high on oxy at the time of an "opiates" test and pass. "Opiates" includes morphine/codeine/heroin. Oxycodone does not share metabolites with those substances. Swim has personal experience with this.

This doesn't mean the OP can go take oxy before the test. It's likely that a pain clinic will order the extended test.

[DrGonzo]

Jury's still out... Yes, this panel included oxycodone (SWIM can say that definitively now).



This wait is murder for SWIM!
