    Default Pre Employment drug test- lorazepam and dilaudids

    Do dilaudids show on a standard pre employment drug test? Also, would one 1mg lorazepam taken 4 days earlier show up on a drug test?
    Thanks in advance!

    Yes on the dilaudid and most likely on the ativan. The ativan might possibly be gone. Sorry!

    Dilaudid DEFINITELY.. I know on a military drug test, they don't test for benzo (know from my son having been in for 19 years and 7 months now). Good luck

    I realize you said pre-employment not military. I bring up military because hopefully if they don't check there where things are pretty rigid, they don't check on the test youll take.

    Most pre-employment drug screens are a five panel test that is checking for pot, cocaine, amphetamines, benzodiazepines and opiates. Hope that helps. God bless.

    Well that sux. I am hoping they wont show because the dialudids were taken on a Sat. night and the test will be Tues evening. He has a prescription for oxys, will that be distinguishable from the dialudids? The lorazepam was taken on Friday night, and it was just one- 1mg, so that is 4 days before the test. This job is really important and we had no warning about the drug screening. Is there a chance he will pass?

    If the dilaudid shows as an opiate the sample will likely be sent to a lab for a more accurate analysis. I don't see you beating that one as the lab would determine what drug it is specifically. The same process would probably take place with the ativan. Can't say for sure, you could POSSIBLY luck by on that one but I see no way on the opiates. Using dilaudid on Sat night and testing on Tues is only three days. That's probably not going to fly. It's tough to beat drug tests when you use that close to being tested. Don't know what to tell you except to stop using, then it won't happen again. I'm not judging you, just stating the facts. Good luck and God bless.

    Default Bunch of misinformation here....

    The rule of ANY drug test is basically 6 x half life of the drug, or often the drug's METABOLITE (be it active metabolite or inactive metabolite). The half life for lorazepam is 12hrs and it's major metabolite is 18hrs. No matter the cut off for concentration, you are basically not going to test after 6 half lives. So after 18hrs, 50% is left. After 36hrs, 25% is left. After 54hrs 12.5% left. After 72hrs 6.25% left. (That's after 4 half lives). After 90hrs 3.125% is left and after 108hrs 1.625% is left (which is 6 half lives and usually an amount so small it is far below any cut off.)

    So if you took Ativan on Friday evening and had test on Tuesday evening that's 4 days exactly or 24 x 4= 96hrs. So you are somewhere between 1.625% and 3.125% @96hrs. No if the weren't testing for the METABOLITE for lorazepam, the half life of drug is 12hrs. So using what we know, 6 x half life (or in this case 6 x 12hrs) means after 72hrs you'd test negative for the lorazepam.
    This also means your chances in the example given of "ativan taken on Friday, tested on Tuesday" has a good chance of passing, BUT also depends on what part of the benzo they were testing.

    The worst part of these ill informed answers are that TYPICALLY BENZOS have the LONGEST half lives of any drug class. OPIATES, like oxycodone has a 3-4.5hr half life. Diluadid (I believe) is even shorter. Morphine can be as short as 2hrs, but 3-4.5hrs is typical for Oxycodone, Morphine, Vicodin and Dilaudid is even shorter. BENZO'S on the other hand, are 12-60hr half lives! Ativan is a short acting benzo 12-18hrs. Xanax is in an intermediate class and can be as long as 26hrs. Klonopin is 40hrs and Diazpam is 60hrs. So just remember the rule 6 x half life and you are clear. After 4 half lives you only have 6.25% of your last dose but really after 6 half lives 1% of ANY amount is a small number even if you where taking amounts high enough to treat a horse for weeks heading into a test. The ONLY note I give is KLONOPIN is a unique benzo. Most benzos go thru many forms of active metabolites before they become an inactive metabolite (which is WHY they have such long half lives). KLONOPIN goes to an inactive metabolite much more quickly and tests often fail to pick that benzo up despite its 40hr half life.

    But... people's responses to Dilaudid being a definite positive test, in this example, are flat wrong. As I said, if needing a "rule" most opiates are under 4hr half lives, making them basically out of the system in 6 x 4hrs= 24hrs. OCCASIONALLY drug tests find other metabolites that have significantly longer half lives than the drug itself or even metabolites of the drug. Cocaine has an incredibly short half life (under 2hrs) meaning it should be gone after
    6 x2=12hrs. (Residue in nose can significantly lengthen, so remember the method of delivery and matter too). I ALSO believe they now have discovered metabolites related to cocaine as indicators of use that can test up to 2 weeks. Prior to that, they had tests for a metabolite that tested up to 4 days. ALL OF WHICH are longer that the 6 x 2hrs=12hrs of the cocaine itself. All that said, just look up the half life of the drug or metabolite of the drug being tested and multiply by 6 and you'll get the number of hours to get out of your system for a test. Even after 4 half lives you are near 6% of the drug remaining which could put you under a cut off and test could be negative. 6 half lives is basically a sure thing, so long as you got the right metabolite being tested.
