tell me about pot and the pee test. please.

so many places anymore make people take a drug test. even for a stupid ass minimum wage job that one can friggin be stoned doing with no repercussions. but. that seems to be the way it is today. so. please. all the experts. i have done some online searching. i do not know how safe they are being in their info. i have gotten information from others that makes me think on line is being really cautious.

take a couple hits daily for a couple months, how long does it take to work out of system to have a clean test? i heard 2, 3 weeks.

have a couple hits and that is it? i hear 2 or 3 days.

what if you take a couple hits. then a week later take a couple hits. then a week later take a couple hits. how long does that take? saying, is it cumulative cause it is taking a couple hits weekly?

help out please. thank you

If you get random tests you should not smoke unless you have like 5% body fat or less - then you can smoke Friday nights.

I know someone like that - he was a Ranger, and whenever they got a weekend leave he and others in his unit would get high on Friday night. They would pee Monday morning and never fail.

Not many people are that fit so you're best off abstaining.

If you're just worried about a new job piss test, smoking once or twice a year is nothing to worry about.

Some people naturally care more about each other, the planet, and many other things in our lives that are far more important than a boss's feeling about my free time. You miss the important things when you're at work.

This is what I do and I don't worry about test. Your body will flush the THC between hits.

The lab will mark the test as a fail if there is evidence of too much water.

I have had clients fail for this reason.
The courts would order another test but an employer probably would just count it as a fail, no chance for re-test.

It is not cumulative but if you are a chronic user your fat cells may store more. My wife was not as chronic as me but she was a daily user and she failed after 3 weeks.

There are things you can do to improve your sample, never give the first urine of the day or even of the particular stream. Do not exercise before giving a sample as stored fat cells might release. You should drink a fair amount of water, since urine really should be light in color, but some will balk if it seems too clear. I have no knowledge that any of the available products will make any difference.

In my lifetime I have passed one and failed one. I recently quit "forever" as it was getting out of hand.

One is your body size and how much fat cells you have since that is where it's stored. 2-3 week you would need at a minimum a month. 2-3 puffs a week, up to a month. 2-3 puffs a month, couple of weeks. There are a few ways to flush your system, your results may vary. Best bet is to find a head shop that sells clean urine, unless you are going to a pain management where you need to have certain drugs in your system and not others.

If you carry a little more body fat and smoke often, it will show on tests a longer than if you are a skinny Minnie and rarely hit it.

I don't trust the things that are supposed to keep your pee clean. If I had a job (and needed the money) that req'd drug tests, I'd simply hold off on using. I however am never going to work again for anyone who will test me. I take oral chemo pills weekly. I partake.

At my lab, THC detection period is up to a week for a single use; up to a month for chronic use.

The scenario you're describing would fit chronic use.

As written above, dilution by drinking lots of water helps. First urine of the day is most concentrated. Catch midstream, not the beginning or the end.

Color doesn't matter. Specific gravity and pH do. Water has specific gravity of 1.000 with pH of 7.0.

Interpreting Drug Test Results

Updated August 2012


Contents:


Drug Test Detection Times: summary for different drugs and detection technologies.

Detection Time for Marijuana in Urine: Urine tests detect non-psychoactive marijuana metabolites for days to weeks after use, long after impairment has passed.

Detection Time for Marijuana in Blood : Blood tests can detect presence of active THC; high levels indicate recent use, low levels may persist for hours or days.

Marijuana Use and Accident Risks : Accident studies show no relation between urine test results and accident risk; presence of THC in blood a moderate risk factor, comparable to low levels of blood alcohol beneath threshold of DUI; high levels of THC or combination of THC with alcohol indicative of DUI.

Drug Test Detection Times for Marijuana

How long do drug tests detect marijuana? There is no simple answer to this question. Detection time depends strongly on the kind and sensitivity of the test employed; the frequency, dosage, and last time of use; the individual subject's genetic makeup, the state of one's metabolism, digestive and excretory systems; and other random, unknown factors.

The basic drug test types and their approximate detection times are shown in the table below.

Urine Blood Hair Saliva
Marijuana - Single Use 1-7+ days 12-24 hrs Doubtful
Not validated

(0 -24 hours?)

Marijuana - Regular Use 7-100 days 2-7 days Months
Amphetamines 1-3 days 24 hours
Cocaine 1-3 days 1-3 days
Heroin, Opiates 1-4 days 1-3 days
PCP 3-7 days 1-3 days

The most popular kind of drug test is the urine test, which can detect marijuana for days or weeks after use. Note that urine tests do not detect the psychoactive component in marijuana, THC (delta-9-tetrahydrocannabinol), and therefore in no way measure impairment; rather, they detect the non-psychoactive marijuana metabolite THC-COOH, which can linger in the body for days and weeks with no impairing effects. Because of THC-COOH's unusually long elimination time, urine tests are more sensitive to marijuana than other commonly used drugs. According to a survey by Quest Diagnostics, 50% of all drug test positives are for marijuana.

Blood tests are a better detector of recent use, since they measure the active presence of THC in the system. Because they are invasive and difficult to administer, blood tests are used less frequently. They are typically used in investigations of accidents, injuries and DUIs, where they can give a useful indication of whether the subject was actually under the influence.

Hair tests are the most objectionable form of drug testing, since they do not measure current use, but rather non-psychoactive residues that remain in the hair for months afterwards. These residues are absorbed internally and do not appear in the hair until 7-10 days after first use. Afterwards, they cannot be washed out by shampoos (though shampoos may help remove external smoke particles that get stuck in the hair). Hair tests are more likely to detect regular than occasional marijuana use. One study found that 85% of daily users tested positive for marijuana, versus 52% of occasional smokers (1-5 times per week). Ingested cannabis was less likely to be detected than smoked marijuana [01]. It is doubtful whether hair tests are sensitive to one-time use of marijuana.

Saliva testing is a newer, less proven technology. The sensitivity of saliva tests is not well established in the case of marijuana. In theory, they are supposed to detect recent use, but this may range from several hours to over a day. They are supposed to detect secretions from inside the oral tissues that cannot be washed out with mouthwash. Because they are less intrusive than blood or urine tests, the industry has been eager to develop saliva tests. Due to reliability problems, they have yet to gain acceptance in the U.S., but they have come into use in some other countries, such as Australia. An international study of various onsite saliva tests concluded that no device was reliable enough to be recommended for roadside screening of drivers (Rosita Project, 2003-2006).

Urine Testing Detection Times for Marijuana

How long marijuana is detected in the urine depends strongly on frequency of use. In regular users (more than once a week), the marijuana metabolite THC-COOH builds up to a high level, often on the order of hundreds of nanograms per milliliter (ng/ml), from which it may take weeks to decline back below the threshold of detection. The situation is different for occasional users (no more than once a week), who often clear up in a couple of days.

Figure 1 illustrates typical urine testing profiles for "one-time" users - that is, subjects who were clean before going into the test. This would typically be the case for the occasional user who indulges a couple of times per month.




(Data on Subjects B, G, E from Huestis and Oral subject from Law).

Subjects B and G illustrate typical "one-time" responses in a group of study subjects. All subjects received a dose of one standard NIDA cigarette [02]. They were monitored for urine levels of marijuana metabolite (THC-COOH) at regular intervals after smoking. Both B and G were positive at the standard cutoff threshold of 50 ng/ml (the standard in most government-required testing programs) for up to two days after smoking.

Note that urine levels of metabolite fluctuate throughout the day. For example, Subject G fell beneath the 50 ng threshold around 24 hours after smoking, but rebounded above it a short time later. Thus it is possible to flunk a drug test despite having passed one a while earlier.

Subject "E" was an exceptional subject who never exceeded 50 ng/ml despite having smoked the same dose as other study subjects. This illustrates the high degree of individual variation in urine testing. While Subjects G and B would likely have flunked a drug test the day after smoking, Subject E wouldn't have.

Occasional use can sometimes be detected much longer, as shown in Fig. 1 by the oral dose from a different controlled study [03]. This represents a subject who was given a strong oral dose of 20 mg of THC, equivalent to a strong brownie or two high-dose Marinol pills. The subject tested above the 50 ng/ml cutoff for up to six days after dosing. California NORML has heard unconfirmed reports of occasional users testing positive for as long as two weeks in exceptional cases. In most cases, however, one-time users are likely to pass after a couple of days.

Time to first positive test

Drug metabolites take time to reach the urine. A user who is clean beforehand can test negative for over 1 - 4 hours before turning positive at 50 ng/ml, as shown in the following data from Huestis [02]. This is similar to the period of impairment after smoking. Therefore, in the case of one-time users, a positive urine test is a sign that the user is most likely NOT currently impaired by marijuana!

Figure 2 - Drug Testing Profiles in First Hours Following Single Use


(Early Urine Test Profiles from Huestis et al. [2])


Urine Testing in Regular Users

In regular users, metabolite levels can build up to background levels above 1,000 ng/ml. Many days or weeks of abstinence are required to clear out, as illustrated in the following graph of metabolite levels in test subjects who were regular users [04A].


Subject B took over a week to fall beneath the 50 ng/ml cutoff, while Subject C took a month. Detection times over three months have been reported in extreme cases.

Note that it is possible to test negative on one day, then positive on the next.

As shown in the following graph, detection times for chronic users typically range from one to three weeks but can extend much longer. In this study by Ellis [04], chronic users were tested at 20 ng/ml and 100 ng/ml, but not at the normal standard of 50 ng/ml.



Blood Tests

Unlike urine tests, blood tests detect the active presence of THC in the bloodstream. In the case of smoked marijuana, THC peaks rapidly in the first few minutes after inhaling, often to levels above 100 ng/ml in blood plasma. It then declines quickly to single-digit levels within an hour. High THC levels are therefore a good indication that the subject has smoked marijuana recently. THC can remain at low but detectable levels of 1-2 ng/ml for 8 hours or more without any measurable signs of impairment in one-time users. In chronic users, detectable amounts of blood THC can persist for days. In one study of chronic users, residual THC was detected for 24 to 48 hours or longer at levels of 0.5 - 3.2 ng/ml in whole blood (1.0 - 6.4 ng/ml in serum) [Skopp and Potsch].

Note: THC blood levels can be measured in two ways. Most labs used by U.S. law enforcement report levels based on concentration in whole blood, but others report concentration in blood serum or plasma instead. Concentrations in whole blood are about half as high as those in serum/plasma. Therefore 0.5 - 3.2 ng/ml in whole blood = 1.0 - 6.4 ng/ml in plasma or serum. Unless otherwise stated, whole blood concentrations are reported here.

In another study of 25 frequent users, 36% showed no measurable blood THC throughout 7 days of abstinence, while the rest had at least one positive, though not necessarily on the first day. Six subjects (24%) had detectable blood THC after seven days at levels ranging from 0.2 to 1.5 ng/ml (that is, 0.4 to 3.0 ng/ml in serum) [Karschner]. There have been anecdotal reports of even higher day-after blood THC levels in chronic users, but these haven't been confirmed in controlled studies.

Unlike urine, blood test results can give a useful indicator of whether one is under the influence of marijuana. Studies have shown that high THC blood levels are correlated with impaired driving. An expert panel review of scientific studies on driving under the influence of cannabis concluded that THC levels above 3.5 - 5 ng/ml in blood (or 7 - 10 ng/ml in serum) indicate likely impairment [Grotenhermen]. The same review found no increased driving hazard at low levels of THC. Despite the fact that accident studies have repeatedly failed to find evidence of increased driving risk at low levels (1 or 2 ng in blood) of THC, numerous states and foreign countries have enacted "zero-tolerance" laws, treating any non-zero trace of THC as legal evidence for driving under the influence. Others have fixed, per se limits above which DUI is presumed, often with no scientific basis. However, most states (including California) don't have per se limits, but define DUI in terms of whether the totality of evidence (including drug test results) shows that the driver was impaired by marijuana or drugs.

Although high blood THC is a fairly good indicator of being under the influence, it is not infallible. Chronic users who develop tolerance to THC may in some cases drive safely with very high blood levels of THC. In one study, a subject with severe attention deficit disorder could not pass a driving test while straight, but performed well with a blood level of 71 ng/ml [Strohbeck-Kühner]. No similar phenomenon is known for alcohol.

Oral ingestion

Oral ingestion produces a much different THC blood profile than smoking. Instead of peaking sharply, THC rises gradually over a couple of hours to a plateau of around 2.5 - 5 ng/ml in blood (5 - 10 ng/ml in serum), then declines (see blue curve in Figure 5).

Blood metabolites
In addition to THC, blood tests can detect cannabinoid metabolites. Not uncommonly, labs report levels of THC-COOH, the same non-psychoactive metabolite found in urine. As shown in Fig. 5, THC-COOH levels for blood are similar to urine. They may be detectable for a couple of days after a single use or weeks in chronic users, and are therefore not a valid indicator of being under the influence. There is no scientific basis for treating drivers who have THC-COOH but not THC in their blood as being legally "under the influence."

Another blood metabolite not shown in Figure 5 is 11-hydroxy-THC, a psychoactive byproduct produced when THC is processed by the liver after oral ingestion. While not detectable at appreciable levels in smoked marijuana, 11-hydroxy-THC shows a similar blood profile to THC after oral consumption. The presence of 11-hydroxy-THC may therefore be used as an indicator of recent oral use. However, most blood tests don't bother to check for 11-hydroxy-THC.

try abstaining for as long as you can, at least 48-72 hours, then try the Tommy Chong Quick Flush capsules.

try finding a High Times or Cannabis Culture magazine.

NEVER give the first morning urine, no matter what part of the stream you catch it from. For an early morning test, get up an hour or more earlier than normal so that you won't be giving them "morning urine" ... after you've peed first, drink water but not too much. You can take a B-vitamin about an hour before the test, to make sure the color is right.

keep us posted!

drug testing is STUPID waste of money!

Fri Jul 18, 2014, 05:40 PM

at least, that's what I've heard.

I've also known people who have passed tests despite having smoked within that window.

It points up the absurdity of those sorts of tests, as others have noted, because things like cocaine or alcohol don't show up after 48-72 hours.

The good news is, at least in many places where people need skilled, smart and creative workers, they've ditched that sort of test. If, for instance, the tech industry started firing all their pot smokers, they'd have no workers left.

Us pot smokers for medical purposes should be able to collect disability since they refuse to give us jobs if we test dirty. They make us either go without medicine for a month, or make us cheat on their tests.

Never have been able to inhale anything whatsoever, but have eaten spaghetti sauce and cookies that had been "enhanced".
I used to be the only person clutching a glass of wine or a glass of Beam and soda at parties. Observed once that the conversation was different than it was at a party where, say, beer was the cheer of choice.
Imagined people standing around saying wow! This PBR is awesome! Who did you buy it from? and so forth.
On the other hand, beer parties could get ugly.
Anyway, not a SWIM, but only because I have never been able to allow myself to inhale anything. Tried, but no dice!
