Passing Drug Test After Taking Vicodin
« on: July 13, 2007, 09:30:25 pm »
A friend of mine has been taking vicodin and needs to pass a drug test on thursday.
I plan on just mailing him a link to this thread.

For the standard tests, I think for opioids or opiate part of the test, they test for morphine, because heroin and codeine break down to it.  There are tests that test for hydromorphone, which hydrocodone does turn to.

What kind of test is it, if you know?

6 days form now till then.  I think the hydrocodone is detectable for only 3 days or so, though.

Tell your friend to stop taking any opiates now until the test and they should be fine, assuming this is a urinalysis.

If the test is for a routine job, most likely they'll be undergoing the EMIT test which is the cheapest and least sensitive of the three standard preliminary tests.  Two days clean should be enough though one should never tempt fate. 

For the other two tests one should be alright after ~4 days clean. 

As for GC/MS which is only done(except in extreme cases) if the lesser test comes back positive, it may detect up to 6 days IIRC.

Best of luck to your friend.

On most drug screen the target molecule is morphine. However, in large amounts hydrocodone and oxycodone cans cause a positive, and at that point a GC/MS can identify those drug metabolites. On the other hand the sensitivity of the opiate screen to those is not as high as it is to morphine, codeine or heroin. If your friend is lucky he/she may be bellow the positive cut-off for hydrocodone. Of course, if a more specific test for hydrocodone/hydromorphone are run, the sensitivity is high. However, most employers or POs only look for those if they suspect such was used.  :|

Vicodin metabolizes into codeine and a few other  compounds. There are a lot of misconceptions regarding the testing procedures. Perhaps I can shed a little light.  These metabolites are generally out of your system after 72 hours. You can effectively mask and pass the UA exam by taking any one of a number of readily sold Detox drinks containing Creatine. The best one I feel is one called: Platinum Detox. It works if done correctly up to 24 hours after cessation of use. I would like to discuss the various ways of testing for Opiates.
The standard tests used for detecting opiates are UA, GC/MS and Immunoassasays. The primary purpose of the opiate test has been to detect morphine and codeine. These are naturally occurring narcotics found in the poppy plant. Both are the central nervous system depressants that relieve pain and are addictive. Both continue to be important medicine, morphine primarily as an injectable analgesic and codeine in Tylenol #3 with acetaminophen as an oral pain reliever and as a cough suppressant. Morphine is also a metabolite of codeine. A metabolite of a drug is formed in the body, primarily the liver, by enzymes that slightly change the chemical structure of the drug to make the metabolite.
Morphine can be made into heroin (diacetylmorphine) by the addition of two acetyl groups. Heroin is made in labs in Mexico, Columbia, and Asia and smuggled into the United States. After injection, smoking, or snorting, heroin is quickly metabolized in the body to 6-acetylmorphine by the removal of one acetyl group and, then, morphine after the removal of the second acetyl group. The consumption of poppy seeds can cause morphine and/or codeine to be detected in urine. This is because the seeds of the poppy plant also contain the naturally occurring morphine and codeine.
The screening tests for drugs are called immunoassays. These tests use antibodies that are produced in animals or cell cultures as part of the immune system. These antibodies are made to specifically bind to a drug such as morphine. However, the morphine antibody will also bind drugs that are very similar in chemical structure to morphine. Codeine is very similar in chemical structure to morphine, as are three synthetic narcotics: Dilaudid (hydromorphone), Percodan (oxycodone), and Vicodin (hydrocodone). The immunoassay screening tests for opiates will detect to varying degrees all of these narcotics. This is true whether the screen is performed in a laboratory by OnLine or EMIT immunoassay, or by an on-site test such as the TesTcup or TesTstikā„¢ device. The synthetic narcotics Darvon (propoxyphene), Demerol (meperidine), and methadone are not detected by the opiate immunoassays.
Heroin, morphine, codeine, Dilaudid, Percodan and Vicodin are all narcotic analgesics that are addictive. A positive morphine screen with TesTcup and TesTstik can be caused by any of these drugs and, also, consumption of several teaspoons of poppy seeds. This is true with all opiate immunoassays, whether lab or on-site rapid screens.
Until recently, the GC/MS confirmation test for opiates generally measured only morphine and codeine. The presence of Dilaudid, Percodan, or Vicodin would not be detected by the opiate GC/MS confirmation, and the confirmation would be reported as NEGATIVE. A NEGATIVE opiate confirmation test may not indicate a false positive by the TesTcup on-site test, but rather that one of these synthetic narcotics is present in the urine specimen. To confirm the presence of these three synthetic narcotic drugs, an Expanded Opiate Confirmation test or Synthetic Narcotic confirmation test would need to be requested from the laboratory. Not all laboratories offer these GC/MS confirmations that include Dilaudid, Percodan, and Vicodin. One source of the Expanded Opiate Confirmation test is LabCorp.
On December 1, 1998, the Substance Abuse and Mental Health Services Administration (SAMHSA) that coordinates federal workplace drug test regulations changed the regulations for opiate testing. Prior to that date, the initial screen by immunoassay and the morphine and codeine confirmation tests was to have cutoffs of 300 ng/mL. Medical Review Officers and Probation Officers had difficulty differentiating a positive test for opiates caused potentially from heroin use from a potential poppy seed positive. The SAMHSA change on December 1, 1998, raised the screen and confirmation cutoffs to 2,000 ng/mL to eliminate most poppy seed positives. They also added 6-acetylmorphine to the confirmation test by GC/MS. The presence of 6-acetylmorphine, the metabolite of heroin, will conclusively show recent heroin use. For workplace drug testing, the SAMHSA opiate changes make sense. It is important not to falsely accuse someone of heroin use, and detecting heroin use is the primary purpose of opiate testing in workplace testing.
However, the 6-acetylmorphine metabolite is detectable in urine for only several hours after use of heroin, while morphine is detectable above the 2,000 ng/mL for about a day. It has been shown that consumption of poppy seeds in most cases will not result in a morphine concentration of 2,000 ng/mL or greater. With no 6-acetylmorphine found, detecting the presence of morphine or codeine. Codeine can be present from use of codeine and from use of heroin. If the codeine level is higher than the morphine level, the source is probably codeine use. Raising the cutoff for opiates from 300 ng/mL to 2,000 ng/mL reduces the time window of detection for heroin, morphine and codeine to about a day after use. It, also, eliminates most poppy seed positives.
The certified drug testing labs have all switched to the 2,000 ng/mL opiate cutoff and many will no longer offer the lower 300 ng/mL cutoff. For criminal justice testing, when confirming a TesTcup morphine positive at the 300 ng/mL cutoff, it is important to use a lab cutoff of 300 ng/mL as well. The TesTcup has had a morphine/opiate test at the 2,000 ng/mL cutoff available since April 1999.
