GC/MS_blues

First I would like to thank S2, N2, Melanotaenia, and all the others for the important work they do. I would also like to let everyone know that I have successfully used S2's dilution and aspirin technique to pass the Immuno-Assay (I-A) type test (I'm a chronic smoker of high quality weed with only 1 week clean at time of test, failing home tests w/o dilution). Often you are given the paperwork that you are to bring to the testing site, which will tell you what type of test you are taking. For my I-A test, my paperwork said the test I would take was "C393-9 Panel/THC". In my experience, anything that says "panel" is the simple I-A test, which you should be able to defeat with S2's dilution/aspirin sticky advice.
Unfortunately, my paperwork this time says "...GC/MS." I am amazed given the information on this site regarding the cost and rarity of this type of test for pre-employment screening (especially since it's for a temp pos. of 2 mos. at a small family owned/operated company, the kind I targeted in my job search to avoid this absurdity). I have read that only abstinence or substitution will work. Maybe it's denial but I'm looking for confirmation that this is the case and that dilution will definitely not help.
I don't have the time window for abstinence (though I am of course abstaining, but only for about two weeks at time of test). If it does come to substitution, I am curious if the GC/MS is too sensitve for synthetic urine (I refer specifically to Dr. John's Pee from Urinator). As far as real urine from a clean donor, I read that after 18 hrs. the pee "goes bad" so to speak, but I also read that if you freeze it it's ok. I also read about using your own dirty urine, letting the water evaporate, scraping the solid concentrates and re-hydrating it test day. What I need to know is which (if any) is my best option. I would love to hear that dilution will work, but if not:
1. Will synthetic urine (specifically Dr. John's) get by the GC/MS?
2. Can I freeze a clean (geographically distant) friend's urine for 3 days?
3. Will my own rehydrated urine concentrates be clean and viable?
Sorry for the length of post but due to it's rarity, GC/MS info is hard to come by. I hope that at least the start of the post helped somebody. Thanks again for fighting the good fight.

PS- Since this info is asked for in posting guidelines, I am a 5"9 F, 116 lbs, pretty high metabolism, daily smoker of high quality for about 4 yrs. now, daily exerciser taking a pre-employment drug test.

In the past I have purchased home drug tests to practice dilution/aspirin timing and to build confidence. In this case, (GC/MS test) is home testing at all useful? Can I practice for GC/MS (outside of substitution logistics rehearsal)? I really appreciate any and all replies or advice and wish luck to all you creative, individual, "outside the box" job seekers who know how to seperate personal life from the professional and chose to unwind at the end of a productive, strenous work day without resorting to alcholosim, prescription addiction and the like.

I am very apprehensive about this test (plus I've been abstaining and may be a little on edge) and keep coming up with more concerns. I am curious as to what the consequences will be if I do fail this test. Will the fact that I failed a drug test be accessible to future employers to whom I consent to a background check? Are there any legal ramifications? I am assuming that the agency who set up the interview will terminate its relationship with me if I test positive. Is this the case? If so, what will be the accesibility regarding this termination to other agencies/employers? These questions may lay outside the scope of these forums but any input will be appreciated. Thanks again.

First of all all your questions lead me to believe you are scared of the big bad GC/MS test! More on that in a second but this first part of your post is kind of giving me a headache. You cant' always tell what the test is going to be from the testing codes. Sometimes you can but those codes are often times a mystery wrapped in an enigma. Plus there is more than one type of immunoassay test. Dlituion can beat some tests and dilution with aspirin can help you beat the EMIT brand of immunoassay test but dilution is not 100% Some people have levels of THC metabolites in their urine that dilution will not work.
Use of GC/MS is not that rare, it is often times used to confirm results from immunoassay tests. It most cases, immunoassay is first performed on the sample then if the immunoassay shows a positive, then GC/MC is run on the sample to confirm.
Since you are curious, it isn't so much that GC/MS is too sensitive, rather a better term would be more accurate. First of all, the sample will probably go through immunoassay first. Since it will pass that, GC/MS would not be run. I don't know if any drug tests go straight to GC/MS but if your sample did go straight to GC/MS it would still pass using synthetic urine. It isn't like the manufacturers are putting in just enough THC metabolites to pass an immunoassay but not GC/MS. The GC/MS is not used to test the validity of the sample either such as specific gravity and pH. They are drug free and pass validity testing.
Can you freeze a clean sample for 3 days geographically distant? Are you shipping and asking if it wil still be good for 3 days if it is frozen the entire time or if it starts off frozen but may thaw and still be good? If it stays frozen the entire 3 days, please do a search on freezing urine because this question about freezing urine is asked and answered many times each week.
You cannot dehydrate dirty urine and make it magically clean. I think you read that section wrong because it is dehydrating clean urine for future use. Why do it this way instead of freezing it? Quicker to go from powder to ready to use than frozen to ready to use and also powder can be stored at room temp.

Can you practice at home for GC/MS? Again you seem afraid of the big bad GC/MS. Do a search on posts from me using the terms "31 metabolites." Use the advanced search feature and make sure you put 31 metabolites in quotes and to the right put in my member name. This will give you an answer about home tests and GC/MS.

Sec3 is the master of this question but I think if this is a non-DOT test, failed results are kept confidential for future tests. Legal ramifications are usually non-existant. As far as taking test for an agency I am sure that depends but usually it can't be good. If the agency sends you for the test before trying to place you I would say they would probably not look to highly on that and may defer you. If the agency doesn't send you but the company that they place you with sends you out I would say the agency would find out you failed. Maybe someone else with experience can tell you.

Thank you so much for your very direct informative replies to all the questions I had. I also followed your search advice and am no longer so intimidated by the big bad GC/MS. My test code does have an SAP 5 before the GC/MS. So you're probably right, with successful dilution I should pass the initial screen and not even need the GC/MS. I'm going to go ahead and get some home tests and practice dilution, as well as getting some synthetic urine and practicing that technique. Considering my home test results, my subbing proficiency (I've never tried it b4), and test site observation conditions, I'll pick the method that works best. I'll be sure to post my details and results in the proper thread.

THANKS!!!

This is probably a stupid question but I have been fired before for mj. I used the urinator with dr johns synthetic for a drug test that I am awaiting results for. My concern is since i carried it in my under garments is it possible for metabolites to make their way into the sample?
