What can't drug tests find

[Chaote]

Ive been doing some reading and it seems that most drug tests, bllod urine salive hair sweat etc cant find LSD is this true what other drugs cant be found or is there a test for all drugs?

[IHrtHalucingens]

mushrooms cannot be detected except for within hours of tripping, so you usualyl dont get caught for these with drug tests, unless ur tripping liek during ur test.

unless special circumstances apply, most places, for instance TASC testing for probation or job application, only test for the NIDA 5 drugs, and sometimes, although rarely, alcohol. Usaully for probation they will just breathalize you seperatly for alcohol, and jobs don't usaully care about it. TASC normally tests for the following 5 drugs, and of course the things that cause false positives for them:
-THC/cannabis
-cocaine/crack
-(meth)amphetamines-ephedrine/sudafed and a few other things cause false positives here, check a list.
-PCP- I hear Dextromethorphan causes a false positive for this and opiates, but I passed a test at TASC 1 or 2 days after robo tripping HARD so I dunno.
-opiates- any morphine based drug like opium, morphine, codeine, heroin, does NOT detect synthetic opiates to my knowlege like methadone or fentanyl, although they may test seperatly for methadone and/or fentanyl. I doubt it.
Anything that is not listed there or causes a false positive for anything that is listed there is not normally tested for, including other phenylethylamines like X and mescaline, tryptamines like shrooms, LSD isn't normally tested for, benzos too. They have special tests they can include to the panel for X, LSD, shrooms, and methadone I know for a fact cause I've seen the TASC testing sheet before, probably some others they specifically test for optionally, but unless they have real reason to suspect you've done something like shrooms within the past day or two, they wont test for it. Hospitals are a big exception, a hospital will test you for just about everything individually. A hospital drug test determined basically every individual drug my friend had taken any time recently, it even showed up with "Oxycontin" not "opiates" but it specifically knew he had done oxy, it detected the benzos he had taken too. TASC does not do that though. Erowid has a very good section on drug testing including false positives and the amount of time it takes to get clean, and how standard a certain substances testing is.

The parting shot is except for weed other drugs generally take 2-3 days to be clean out of your system typically, 5 days and almost anyone should be in the clear. Pot on the other hand takes a long time to get out of your system, most people it takes about a month for a heavy user to be clean. In my personal case it takes 3 months from light/medium usage to be clean. TASC and my PO both say that 3 months for light/medium usage is IMPOSSIBLE. Well I testify that it is most certainly possible, and I'm not a lardo or anything, at the time I was 6 feet tall and probably around 160-170 lbs. I've talked to other people who have been clean from chronic potsmoking in less then a week. Oh, that 2-3 days is for a urine test btw. It takes more time to be clean for a blood test for non-pot drugs, and less time for pot. I personally was clean for a blood test in somewhere between 1 and 2 weeks for pot.

This is not true at all. The detection time is anywhere frim 1-3 days, and there are always exceptions. Mushrooms are not included on the standard 5 panel drug test but extended drug tests sometimes include them.

yes, you are correct. i should think more before posting. i apologize.

Drug tests have so many variations its not funny... It would be hard to put all of these into one basket and say it is safe to do this or it is safe to do that... It really depends on the extent the testers are going to go in order to determine the accuracy of the result... Like it would be much much harder to beat a test for the "olympic games" than say pissing in up a cup for a "parole officer"....

Most places that have to do alot of them regularly don't send out to a lab and just use panels (and the convinience that there can be a 5 day turnaround time on lab samples)... Panels are often easy to defeat with diuretics being able to reduce concentrations below the "threshold" at which a postive result is displayed...

On the other hand, if samples are sent out to laboratories, labbies can easily tell that one has just masked their samples by hyper-hydrating as diluted concentrations of common metabolites will be found in the urine (like creatinine is ususally found in very predictable concentrations in urine)...

For this reason Gas chromatography (GC-MS) is going to be hard to defeat for anything if the drug has been consumed within that danger period of the drugs "half-life" as they usually give results based on the metabolite:creatinine ratio rather than the outright "concentration" of metabolite itself... Here is an example;

Quantitation of THC metabolite concentration is sometimes useful in assessing if the patient's denial of recent drug use is consistent with a positive test result. The basic assumption is that the higher the urine drug concentration, the more recent the exposure. Interpretation of urine THC metabolite concentrations should be done with the following limitations in mind:

1. Assay is semi-quantitative. The immunoassay used in THC SEMI-QUANT does not measure just one compound or THC drug metabolite. Instead, it detects and measures dozens of structurally related THC metabolites. The test reports a "concentration" for THC metabolites, but this is not the actual concentration of one particular THC metabolite because there is no way of discerning the contribution of the other metabolites. INTERPRETATION OF "CONCENTRATION" SHOULD BE DONE WITH CAUTION. A positive test suggests exposure to marijuana, but the significance of minor changes in "concentrations" with time should be carefully evaluated with the semi-quantitative property of the assay in mind.
2. Patient's hydration status. Urine drug concentration varies with urine volume, which in itself is dependent on how much fluid the patient has consumed (patient's hydration status). In a urine specimen obtained from a patient who has consumed a lot of fluid to "dilute" his urine, the drug concentration may fall below the test cutoff to give a negative result. Conversely, the same amount of THC metabolites in a specimen from a dehydrated patient will be present in a higher concentration to possibly trigger a positive result. One approach to overcoming this variation in test result due solely to changes in the patient's hydration status is to calculate the THC Metabolites:Creatinine Ratio. Creatinine, a natural breakdown product of body metabolism, is excreted into urine at a fairly constant rate regardless of the volume of urine. Therefore, expressing THC metabolite concentration as a ratio to the amount of creatinine can reduce the variation in drug concentration due to changes in urine volume. This approach can be helpful in following a patient's THC metabolite excretion pattern longitudinally.

Testers are looking for the metabolites too usually, not the "drug" iteslf... How long these stay in one's system is easily predicted by the "half-life" of the compound... Same with all drugs... Anyway that is enough rambling lol...

So at the end of the day... If one does want to beat panel testers, diuretics and HEAPS of water are the key... SWIM has seen someone smoking bongs till like 2 hours before a "parole officer" urine test, through this period and for the 2 hours after, water was consumed at about the 4L range and constant urination was well under way... Dude pissed clean as a whistle at the test... SWIM has seen it done by many others also so it does work BUT if the tests are going to a lab its totally dependent on the drugs "half-life" so give up now!!!

Peace out... And good luck to all who have to go through the drama of a drug test..

Yes, beating a 5-panel drug test can be done with ease, but there is one problem. If they suspect that the subject intentionally consumed a large amount of water, or the sample was diluted, some places send the piss to a lab to be tested. I actually think many places do this to clear up false positves and false negatives. Some places will reject a sample that shows the subject drank unusually high amounts of water.

so then would taking lots of creatine in capsule form help a urine sample appear to be less diluted than it actually is?

[raven3davis]

If the drug test is advanced enough it can test for nearly anything including lsd and shrooms. No standard test will find these drugs but there are drug specific tests that can find basically anything. DOM, DOB, lsd, tryptamines steroids, pharmecudicals. The sky is the limit.

Good Point... Actually a very good point... Since the majority of creatine ingested does not enter the cell (even with insulin spikes and all the other methods used to try transport it into the cell), most of it would be metabolised to creatinine in the kidneys and expelled in the urine...

This could work to fool some tests into believing that the urine was in fact not diluted by excess water consumption and would yield the desired negative drug test result...

This would only work on a test that uses a drug:creatine ratio to compensate for dilute urine samples though... A full blown lab test could still determine whether the sample was dilute by complete profile of metabolites more than likely...

In summary though... Excess water, diuretics and creatine supplementation could definately aide in helping one pass the majority of drug tests that are performed in this day and age providing the tests don't involve a complete lab workup...

That is something to to... lol
