but the test is expensive
they generally only do it
if they suspect use.

the risk & danger is still very real-
it's a crap shoot.
most times the form your P.O. fills out ordering the drug test is multiple choice,
ranging from amphetamines to opiates and cannabis, etc.
how many boxes he/she checks varies,
i've heard of 6-way tests that tested for six drugs at once but sometimes they just test for one,
almost always cannabis.
but you'll not know until too late.
so be prepared for consequences
if you take the risk and lose the bet.
your P.O. doesn't care
how much the test costs,
not his/her money.

The day before I had smoked a lot of pot and I was nervious as hell. Anyway, I just "ran late" the day of my meeting.
He already left for the day, and I didnt have to pee. They never tested me.
Two things to keep in mind was the fact that my po appeard to like me, and I was not there for a drug offence.
Im not sure how your po would handle it if you just blew off a drug test, mine didnt seem to care.

a urine test
is normally treated the same as
i.e. a violation.

In short, they don't know what the hell happens to this substance at that juncture. If they have gotten it down to doing urine test with LSD I'd be suprized, because one of the problems with testing for acid is the weight. When one tries to follow micograms (say maybe a good 300 parts per million) throughout the body it get increasingly difficult.
The basic way they test is by the weight of the substance in the urine, that's why it took them so long to come up with a more reliable THC test. I remember the first time I was that I got locked up for 45 days in a work camp scenario, they only had a saliva Test that could be employed if the man caught you smoking, and that had to usually be within the first 15-20 for the test to have any degree of accuracy.
Granted, big brother has come a long way towards testing for everything, and one day they will have the technology to test for everything, however, there are always miscreants like me that will assidiously seek to escape Government control. Buzz on brothers.

if u scroll most the way down to the drug testing part it has some good info on lsd testing.
Drug Testing No risk. Its not looked for, hard to find, and transient. A maximum concentration of 2-8 ng/ml [Plasma concentration of LSD] was reached 1.0-1.25 h after an oral dose of 160 ug. ...[A] value of 2.9 h for the elimination half-life of LSD from plasma [was reached]. [Upshall, D.G., Wailling, D.G.: The determination of LSD in human plasma following oral administration. Clinica Chimica Acta 36, 67-73 (1972)] Second of all, LSD and its metabolites are detectable in the urine for much longer than one hour. "LSD and its metabolites were still detectable in human urine for as long as 4 days after the ingestion of 0.2 mg of the drug. [Faed, E.M., McLeod, W.R.: A urine screening test of lysergide. Journal of Chromatographic Science. 11, 4-6 (1973)] Note that standard, cheap initial drug screening does not use chromatography or mass-spectrometry, and does not look for LSD. Spinal taps are not particularly useful (cerebro-spinal fluid doesn't concentrate LSD or metabolites) and are never done under any circumstances: they are painful and dangerous. You might want to mention that Abbie Hoffman's _Steal This Urine Test_ has a table which claims lsd is detectable for 40 days. I'm almost sure this was a typo 1] How long can LSD be detected in the body? This varies by the test being used, the detection limit placed on the test, the point of collection and type of the sample fluid, the amount of LSD that was taken, and the individual in question. Assuming the testers are using an RIA screening test with the cutoff set at 0.1 ng/ml and assuming that the user has recently emptied their bladder, then the detection limit for one hit (100 ug) is normally around 30 hours. Each doubling of the initial amount will add about 5 hours. Thus taking 8 hits will leave a user vulnerable for approximately 2 days. (NOTE: This is based on the data in ) >
2] What exact form of test can be used to detect LSD in the body? There are a number of tests which can be used to detect LSD in the body. Abuscreen, a product of Roche Diagnostic Systems, is a series of RadioImmunoAssay (RIA) tests, one of which is used to detect LSD and its metabolites in whole blood, serum (blood), urine and stomach contents . RIA can in theory be used to detect quantities as small as 0.020 nanograms (ng) per milliliter (ml) of sample . Laboratory tests have shown that RIA results are accurate down to at least 0.1 ng/ml . The manufacturer recommends limiting the cutoff to 0.5 ng/ml. EMIT, a product of Syva Corporation, is another series of tests, one of which can be used to detect LSD and its metabolites in serum and urine. EMIT stands for Enzyme Multiplied Immunoassay Technique. Both EMIT and Abuscreen are "positive/negative" response tests (much like pregnancy tests) which require periodic equipment calibration and consume chemicals for each test performed. A basic battery of tests costs approx. $15-$25 per person . The basic tests (recommended by NIDA) include marijuana, cocaine, amphetamines, opiates, and phencyclidine (PCP). Normally, unless an (employer) specifically requests the test, an LSD assay is not run. Both Roche and Syva recommend confirmation of positive results by using a different test. The usual method of confirming positive results is some form of chromatography. These include High Performance Thin Layer Chromatography (HPTLC), and different forms of Gas Chromatography/Mass Spectrometry (GC/MS). HPTLC and GC/MS can be used to give quantitative results as opposed to the Boolean results from EMIT or Abuscreen. Laboratory tests have shown that GC/MS test for LSD in urine and blood can be accurate down to 0.1 ng/ml. The cost for confirmation of a positive screening test is approximately $50-60. Positive results to either EMIT and RIA are held to be "probable cause" by U.S. courts. GC/MS results are held to be "proof" by U.S. courts. > I am asking for an actual text message containing a short, precise > description of each test, Immunoassays chemicals are created by injecting animals (rabbits, sheep, donkey, etc) with the drug to be tested for and an albumin which force the animal to produce antibodies. The antibodies are then removed from the animal, purified and bottled. In RIA tests, the antibodies are then added to the fluid sample with a radioactively labeled chemical. Any of the drug (or similar chemicals) found in a sample that is being tested will react with this glop and by measuring the radioactivity, the amount of drugs can be determined . > 3] How can such a test be beaten? While there is some literature on adulterating urine samples to produce false negative results , there has been little written that applies specifically to the LSD screening tests. I would suggest you read the article posted by Paul Hager paying particular attention to the warning about water intoxication : In [email protected]> [email protected] wrote + Recommended: "Dealing With Urine Tests on Short Notice" + by Dale Gieringer, California NORML + + Most folks recommend that people hydrate themselves -- the idea + being that by drinking water and taking a diuretic that will + promote water loss, the urine will be very dilute and THC metabolite + content from "tomatoe" consumption will drop below the 100 ng/ml + threshold that defines a "positive". + + Mr. Gieringer recommends that, the day before the test, the + person drink lots of water. I would amend this to, drink your + normal "8 glasses" plus a few more. Don't get carried away with + drinking water -- there is such a thing as "water intoxication" + which can result in brain swelling and other nasties so don't + chug-a-lug a gallon of water just before the test.

The immunsoassay tests vary in their specificity. Some display a relatively low cross-reactivity, others a high cross-reactivity. The exact metabolites of LSD in humans have not been fully determined yet, though animal studies have been done. The only verified human metabolite I could find in the literature was N-demethyl-LSD but I did not check all the references. LEGAL SCHEDULING: Class I, "no medical use" --- mostly for political reasons, as it was and is used in psychotherapy. (Current use is in Switzerland.)
