Most pre-employment urine screens use the NIDA 5 standerd drug creen regimine. As the name implies, they check for 5 substances most commonly abused in the US (at least what narcs think people use the most. The substances tested for are
1.
Methamphetamine (the screen will also trigger for
amphetamines,
ritalin and just about any other amphetamine-like stimulant)
2. Cannibis
3.
Cocaine
4. Heroin (since most 6-acetyl
morphine (heroin) is converted into morphine very quickly by the bosy, these screens typically test for morphine, which will also trigger for
opium, heroin or
codeine but NOT for other opiates like
methadone,
oxycodone and hydromorphone)
5. PCP
so if the NIDA 5 is the test you have to take, than no it shouldn't trigger for oxy or MDMA and you don't neet to worry about detox.
BUT
if it's an extended drug test, and some employeers do spring for the extra regimines, than you will be tested for an additional 5-10 substances, depending on how many drugs the employer wants to pay to include. These tests do offer to test for both oxy and MDMA, so you may want to find out what kind of test they perform. Mind you this is only for urine sceens. Blood and hair tests are different and I'm not as familiar w/ them.
Also, not that the quality and purity of street "X" tabs are notoriously poor, and if you ingested "ecstacy" tablets prior to a drug screen you may test positive for any number of substances (esp. methamphetamine) since street ecstacy is often adulterated with other drugs like methamphetamine and DXM (which can cause false positives for PCP and morphine).
