Passing a Drug Test - Is It Legal?

Your specific drug testing situation may vary but if you are applying for employment in the private sector you may very well not be violating any laws when you attempt to pass a drug test.

This is the statement made by the Department of Labor Workplace Advisor::
The majority of employers across the United States are NOT required to drug test and many state and local governments have statutes that limit or prohibit workplace testing, unless required by state or Federal regulations for certain jobs. Also, drug testing is NOT required under the Drug-Free Workplace Act of 1988. On the other hand, most private employers have the right to test for a wide variety of substances. It is very important that before designing a drug-testing program you familiarize yourself with the various state and Federal regulations that may apply to your organization.

With that said the please verify the legalities of trying to pass your drug test and keep in mind the easiest way to pass a drug test is not to take drugs in the first place.

Can I Pass a Drug Test?

There are many techniques floating around for flushing your body free of drugs or tricking the tests by loading up on herbs, certain foods, magic detoxifier pills, coffee, etc. There are more about spiking your specimen with adulterants. But many are myths.

For example, there is speculation that loading up on water before a urine drug test might dilute drugs and metabolites just enough, to put them below the cutoff levels. But, lots of water makes your urine look pale. It's a healthy sign that you're well-hydrated, but also a waving flag that you might have tried to "flush." NORML, a group working to reform marijuana laws, suggests that you might be able to beat watery-urine detection "visually" if you also take vitamin B-2, which tints your urine yellow.

Another myth is about claiming to be a "passive" user, like by incidentally inhaling ambient pot smoke at a rock concert. You can try using that excuse, but if you're a regular pot smoker, it likely won't fly. Your level will probably be above the cutoffs and far above that of the passive smoker, which, at only about 5 ng/ml or so, is well below the cutoffs. The same goes for passive absorption, like from maybe handling a dollar bill that was unknowingly rolled into a "straw" to snort coke. But, nice try.

It's true that poppy-seed ingestion can cause false positives for opiates a few hours later in urine tests. But labs claim that hair analysis can distinguish between opiate abuse and poppy-seed ingestion. Additionally, the Feds are familiar with urine-adulteration tricks. Consequently, the Feds upped the ng/ml detection level beyond that of "normal" poppy-seed ingestion, but still within the range of abuse. Normal ingestion is considered to be like two poppy-seed muffins in a day, tops.

Don't rely on excuses

Although urine tests are far from infallible, it is difficult to challenge positive test results. "False positives," in which workers are wrongfully accused of marijuana use, are highly unlikely so long as labs exercise proper care (however, not all labs do this). The standard procedure is to first screen the samples with an immunoassay test (e.g., EMIT® or RIA®), then confirm positive results with the more accurate gas chromatograph mass spectrometer (GCMS). This virtually eliminates the chance of false positives in exchange for a relatively high rate of "false negatives," where drug use is not detected. The sensitivity of the test is determined by the concentration of metabolites it is set to detect: for the Dept. of Transportation, the standard cutoff is 50 nanograms/milliliter (ng/ml).

No substance is known to produce a false positive for marijuana. It used to be that ibuprofen (Advil, Motrin, Nuprin) interfered with the marijuana test, but this problem has been fixed. A variety of over-the-counter medicines can cause false positives for amphetamine and other illicit drugs on the EMIT test, but not on the GCMS.

"Passive smoking" of marijuana is not an acceptable excuse at the 50 ng/ml level, since only in extreme circumstances can a non-smoker absorb enough pot to test urine positive (e.g., being stuck in a closet full of heavy smokers for hours). However, passive exposure may result in positive tests at 25 ng/ml or lower.

Know your rights

Make sure your employer has the right to test you. Additionally demand they give you their drug testing policies in writing. Your employer should know if the testing facility is accredited. They must advise you as to the testing procedure and what steps are to be taken in the event of a positive test result.

These are legitimate concerns and should legally be answered up front. If they cannot answer them they make back off the test completely.

If you fail your drug test

Be cool & don't rely on excuses. If you fail your drug test don't pitch a fit. Inform them that this is 'simply not possible' and ask them how this could possibly be. Do not volunteer any other information. As far as you are concerned failing the drug test was never even a remote consideration in your mind. Ask them what you can do about this situation and see if you can retest at a later date. Your best reaction in this situation is puzzlement, not anger. Reasonable cooperation is the best approach. Remember, if you want the job you will need to re-test at some date. Your best chance of this is cooperation and putting the test date off as far as possible.

Detox Products to Pass a Drug Test

Over the past decade a number of highly effective detox products have come to the marketplace in response to the increase in drug testing. Hair follicle shampoos for passing hair drug tests, urine additives and flushing agents for passing urine drug tests and saliva solutions for passing saliva drug tests. Many of these are quite effective but with many industries some of them just do not work.

Using common sense

When selecting a detox product here are a few guidelines:

  1. Do they answer the phone when you call for support?
  2. Is the support staff knowledgeable?
  3. Do they offer a money back guarantee?

Most of these questions are common sense and should be considered when purchasing any product but in the panic to find a detox product to pass your drug test it is easy to lose track of common sense.


Please note that the use of these products may violate local, state or federal laws. In instances of court ordered drug tests use of these products is most certainly illegal and may result in additional charges, sentencing or violation of parole. Please determine the legality of using these products prior to using them.

Passing a Random Drug Test

From time to time you may find yourself in a position wherein you need to pass a random drug test. And the fact is, if you are a drug user failure to pass a random drug test can completely destroy your life.

At the very least if you fail to pass your random drug test you will be placed in a company controlled rehab program.

Additionally, if you fail to pass your random drug test it can get much worse than that including loss of job and incarceration. The additional stress these occurrences can add to peoples lives have led to the failure of marriages and the loss of children.

Your best bet in this drug testing situation is to put the drug test off as long as possible to give yourself some type of an opportunity to purchase a detox product.

If you are confronted with a random drug test act calmly. If you must provide them with a sample immediately, do so. You may test positive but the time to deal with that is after the drug test results come back, not before you have even failed the test. If you fail the random drug test chances are very good that you will be allowed to retest once the results are returned. Your best bet is to calmly give them the required sample, leave and begin an immediate detox effort, then retest at a later date if you do indeed fail your random drug test.

Remember, non drug users do test positive and actual drug users can test negative. It may be your lucky day so keep your head about you until there is an actual problem.

Passing a Urine Drug Test

A urine drug test, also known as urinalysis, this procedure requires that one provide a sample of urine. Either a test card is used on site for immediate results, or the sample is sent away to a lab to undergo gas chromatography/mass spectrometry (also known as GCMS), high performance liquid chromatography or immunoassay analysis. The majority of tests administered in pre-hire and even most probate scenarios are of the immediate, and less accurate "at home" variety. Most "dip stick" type tests have higher thresholds for a postive than do the GCMS tests. If a positive result (drug presence indicated) is found, the sample is usually sent to a lab for GCMS confirmation. This is largely due to the costliness of GCMS labaratory testing and time it takes to process and receive results.

There a number of products on the internet including urine additives, masking agents and detox products to flush your urinary tract of toxins. The first 2 are risky and easy to detect, the final 'flushing' method to pass a drug test is the best option.

Urine additives to pass a urine drug test

TAMPERING: While urine dilution is useful, it isn't 100% reliable, especially for heavy daily users. Another tack used by some people is to tamper with the sample by adding adulterants or substituting clean urine for their own. Ethical issues aside, tampering is risky since subjects may be observed or made to disrobe beforehand, and cheating isn't forgiven. For the adventurous, Abbie Hoffman's book Steal This Urine Test has full instructions on how to rig yourself up with a plastic bag to substitute clean urine. You can buy clean, dehydrated urine but beware -- labs check to make sure the temperature of urine samples is right (around 91-97ƒ).

Another trick to foil the test is to spike the sample with an adulterant. This approach should be used only as a last resort, since any adulterant can be chemically detected if labs take the trouble to do so. A number of adulterants cause negatives on the commonly used EMIT test, but not necessarily other tests. In an emergency, you might fool an EMIT test by adding a few drops of Visine® to the sample. Other common adulterants include detergent, bleach, salt, and the cleaning solution glutaraldahyde, but most of these are easily detected by smell or visual inspection. A host of commercial adulterants are on the market (for advertisements, see High Times). Among the more popular are Klear® and Whizzies®. No additive is 100% reliable, and all involve a substantial risk of detection. Many drug testing companies claim to test for adulterants, though it isn't clear how carefully.

You must be very careful when using a urine additive to pass your urine drug test:

  1. Urine additives can be detected.
  2. If you are caught with the urine additive in the drug test environment expect the worst possible outcome.

Urine masking agents

This is an old school approach to passing a urine drug test. Basically some type of adulterant (bleach, etc) is added to the urine sample. This type of method to pass your urine drug test will most certainly be detected by modern lab drug testing procedures.

Flushing agents to pass your urine drug test

By far the best method to pass a urine drug test. These typically work by flushing toxins from your urinary tract so that your urine sample is clean when given to the testing authority. Advantages are as follows:

  1. Typically works within one hour.
  2. Undetectable.
  3. You bring nothing into the test environment.

Below are some guidelines for naturally flushing toxins from your system. While these guidelines are sound advice it is best to use some type of commercially available flushing agent to accelerate this process and guarantee you pass your urine drug test.

WASH YOURSELF OUT: The general strategy for passing urine tests is to increase your fluid intake and urine flow so as to dilute the concentration of drugs in the sample below the threshold of detection. An hour or two before the test, you should fill your bladder with fluids - as much as you can drink. Water is fine - contrary to popular rumor, there is NO evidence that goldenseal, vinegar, niacin, or vitamin C help. However, high-dosage aspirin may reduce the sensitivity of the EMIT urine test for pot (only). Many people wash themselves out for several days in advance by drinking a lot and exercising, but there is no reason to think this is useful. In no case should you give your first urine of the morning, since drug metabolites tend to build up during your sleep.

While you're loading up on water before the test, you may also want to take a large dose (50-100 milligrams) of vitamin B-2, available in B-complex multivitamins. The purpose of this is to color your urine yellow, since otherwise you are likely to produce clear, watery urine, which makes some collectors suspicious (contrary to rumor, vitamin C won't help). In rare instances, some labs will reject a sample for being too watery; in this case, however, they will typically give you a second chance. Wait until your test results have been confirmed before indulging in compromising behavior.

You can boost your fluid output by taking diuretics, which stimulate urination. Weak diuretics include coffee, cranberry juice, certain health food products and over-the-counter pills for pre-menstrual water retention.

If you're taking the test on very short notice, you may wish to resort to more potent diuretics, which are widely prescribed to treat high blood pressure. Although strong diuretics, such as furosemide (Lasix®), are available only on prescription in the U.S., they can be had over-the-counter in Mexico and other foreign countries. Beware that they can be dangerous for certain persons, such as diabetics or pregnant women, and can cause problems if taken over extended periods. Diuretics can be detected in urine, but are rarely checked except for athletes. The following regime has been suggested by a former army drug testing officer (Robert Freeman, "How to 'Beat' a Drug Test," High Times, Aug. 1988): Take an 80-milligram dose of Lasix; take a hefty drink of water; piss two or three times, then take the test. If you're lucky and didn't smoke too much pot, a good washout may get you past a test on a couple days' notice. However, regular smokers should allow at least a week or two if at all possible.

While the above steps can assist you in passing a urine drug test it is best to use some type of commercially available flushing agent to accelerate this process and guarantee you pass your urine drug test.

Passing a Hair Drug Test

Hair testing is quite accurate and can go back normally 3 months (6 months or longer possible with specialty tests), showing any drugs of abuse used in the detection window. As hair grows out, any drugs used are encased in the hair shaft, so the longer the hair, the longer back in the individual's drug history the lab can detect. Accredited hair drug testing labs, however, only use hair within about 2.5–4 cm of the scalp, and discard the rest. With head hair each 0.5 inch (1.27 cm) corresponds to about 30 days. This limits the detection history to about 90 days, depending upon the rate at which the individual's hair grows. Some people attempt to circumvent this through shaving their heads. In the absence of the required amount of hair on the scalp, body hair can be used as an acceptable substitute.

How to pass a hair drug test

There is no easy way to pass a hair drug test other by the use of a hair follicle shampoo. These shampoos are designed specifically to pass a hair drug test and accomplish this by stripping toxins from the hair follicle shaft.

Some individuals have been known to shave their heads in an effort to thwart having to take a hair drug test. This attempt is usually for naught because the hair sample required for the test can be removed from any part of the body including pubic, armpit and chest hairs.

Passing a Saliva Drug Test

Saliva / oral fluid-based drug tests can generally detect use during the previous few days. Saliva or oral fluid based drug tests are becoming more prevalent because of their convenience and the fact that they can not be adulterated. Furthermore, on-site oral based tests in particular enable the implementation of random testing programs, proven to be the most effective type of drug screening. Oral fluid based tests are as accurate as urine and can be obtained from quality suppliers in the United States.

Testing is usually performed by employers, for either pre-employment, random, post-accident, reasonable suspicion, or return-to-duty testing. Oral fluid based testing most closely mimics results found with blood and is preferable for detecting on-the-job drug use or in post-accident applications in this case because the degree of intoxication can be approximated based on the amount of substance.

How to pass a saliva drug test

Saliva drug testing is basically based on blood. The only hope you have of passing a saliva drug test is to use some type of saliva drug test solution. What these solutions do is basically destroy the drug toxins in your saliva so you can provide a clean test sample to the testing authority.

Passing a Blood Drug Test

Blood tests are the most expensive and most intrusive form of drug testing. They are also the most accurate method of testing the least common because of the expense. Blood tests are not very popular due to the widespread fear of blood borne infectious diseases. Blood test also has a short detection period and requires trained phlebotomists to take to the blood from the individual.

Blood tests cannot only be used to determine if you are using recreational drugs, but they can be used to determine if you are on any other types of medications. Blood may be used for testing for alcohol, but only within a few hours after alcohol has been ingested. If an individual is an alcoholic, there may be a longer available window due to the build-up of alcohol in the blood.

How to pass a blood drug test

At this time the marketplace offers no reliable product to pass a blood drug test in a short amount of time. The only guaranteed ways to pass a drug test is to not to do drugs or to let your body naturally detoxify. There are a number of ways to speed up this detoxification process such as an increase in excercise, consuming naturally detoxifying foods and increasing your intake of water.

Passing a Sweat Drug Test

Sweat tests are patches attached to the skin to collect sweat over a long period of time (10–14 days).

These are almost exclusively used by child protective services, parole departments, and other government institutions concerned with drug use over long periods, when urine testing is not practical.

The patches have security features that keep them from being covertly removed and then reapplied without the knowledge of the testing agency. At the end of the test period, the patch is removed by a social worker or parole officer and sent to a lab for analysis. If the person has used any drugs during the period that the patch was in place, they will test positive for that drug.

This type of testing has fallen out of favor with government agencies due to documented problems with certain drugs.

How to pass a sweat drug test

A sweat drug test is remarkably similiar to a blood drug test and at this time the marketplace offers no reliable product to pass a sweat drug test in a short amount of time. The only guaranteed ways to pass a drug test is to not to do drugs or to let your body naturally detoxify. There are a number of ways to speed up this detoxification process such as an increase in excercise, consuming naturally detoxifying foods and increasing your intake of water.

Naturally Passing a Drug Test

Please keep in mind that none of the below steps can guarantee that you will pass your drug test. They can however be an excellent aid.

Your best bet to pass your drug test is to try a reputable detox product to pass a drug test.

Know Detection Periods

You may not even need to take steps to pass a drug test. If you are in doubt stop by your local pharmacy and pick up a drug test and test yourself. Many parents test their teens so picking up some type of store bought drug test should not raise any eyebrows.

Avoid Using Any Drugs

Avoid being around others consuming drugs at least 48 hours before your deadline, a week if possible. In general, the longer the better. Your first line of defense is always abstinence. The exception to this if that if you have a prescription to use certain drugs, continue the use of those.

Water Consumption

For at least (2) days prior to the day of your deadline consume a minimum of (6) 16 ounce glasses of water per day. Water is a catalyst to the body's natural detoxification process. Drinking water will help to flush drug metabolites out of your body, especially when combined with healthy eating and exercise habits. Just keep some water by you and sip on it all day long. You can drink several glasses this way without having to drink the water all at once.


Exercise the week leading up to your deadline. Aerobic exercise raises your metabolism which assists greatly in the detoxification process. Exercise every day up to 48 hours before your drug test. To burn the metabolite-containing fat cells, exercise regularly every day (twice a day for 30 to 60 minutes if possible). Be active. Climb the stairs at work. Walk the dogs for an extra hour. Stand at your desk. Walk to the corner store instead of driving. Do whatever it takes to burn the fat and boost your metabolism - but do NOT diet. On the other hand don't gorge. (We're trying to burn fat, remember). It's much better to eat often than to overeat at any one sitting. Anyone who has ever stuffed themselves knows that they certainly don't feel a big boost of energy afterwards. Eat things that give you energy, but avoid excesses of quick metabolism boosters such as coffee, sugar and Red Bull. Especially when taken in large quantities, these will be consumed by the body quickly and lead your metabolism to 'crash' as soon as the sugar and caffeine runs out. You want to keep your body metabolism at a steady, hearty pace all day long.


  1. Incorporate a healthy diet the week prior to your personal deadline. High fat foods, greasy foods (particularly butters, cream sauces, and fried foods) and junk foods have been shown to slow the detoxification process. Eat fiber, carbohydrates, vegetables and foods high in protein as normal. Do NOT skip breakfast. Eat often throughout the day, but avoid eating late at night when your body has nothing to do with those extra calories other than store them as fat. Do NOT go on a crash diet to burn fat. When you diet your body panics because it thinks you're starving. Your metabolism will drop and your body will hold on to those fat cells even tighter than before.
  2. Consume only light meals the day of your personal deadline.
  3. Avoid alcoholic beverages, over the counter drugs and unnecessary medications.

Creatine Levels

Maintaining Creatine Levels is a Key. THIS IS REAL IMPORTANT STUFF: Creatine is a natural protein created by the body and is usually excreted in the urine at fairly constant concentrations. When the urine is diluted by frequent urination and extra hydration, the creatine level in the urine will drop. Creatine levels are tested for in labs and a low creatine level may indicate to the lab that you have attempted to flush your system of drugs.

Steps to be used as a last resort

  1. Switch samples. Get a urine sample from a friend who will not test positive, conceal it and carry it to the test site, and pour it into the collection bottle. Most tests require about 100 ml of sample, which can be easily stored in a ziploc bag taped to your body, or underneath the soles of your shoes. Although most testing sites will require you to remove items from your pockets, it is still possible to sneak in another sample.
  2. Drink lots (2 gallons) of cranberry juice if you have been doing cocaine and you can get it out of your system in a day.
  3. Substitute your urine for some synthetic urine and make sure it is the recommended temperature range of 94°-100°F

Why avoid these steps to pass a drug test?

  1. Sample Switching: Unless you are certain that your drug test will be unsupervised it is very risky to bring any type of urine substitute into the testing environment. If you are caught with an outside urine adulterant chances are you will be reported to the testing authority.
  2. Drinking excessive amounts of water over short periods of times is a health risk. Death may result.

Additional Tips and Ways to Pass a Drug Test

We are currently in the process of importing this pass drug test ebook information, ( with permission of course ).

Thank you for your patience.


  • Urine replacement - Most places now make sure that the urine is at body temperature. You can accomplish this by putting a container, such as a small shampoo bottle, under your arms, or inside of you, and take out once in a safe spot. If you try this you are in the clear. It is a myth that most facilities make you strip before you take the test.
  • Be careful! Foreign objects may break or get stuck, causing serious health problems!
  • Tampering with drug test results might bar you from employment to the company. The results may also be sent to law enforcement, depending on the employer.
  • If asked to take a drug test, act natural. Some employers, schools and parents will ask you to take one just to see your reaction, there is no point to getting all in a huff unless you are being taken by suprise to a testing facility (illegal unless you are under 18 and are being taken by parents or those with parental consent) at which point, take a minute to think and find a good excuse to prolong testing. Every second could count.
  • At least ten states (Arkansas, Illinois, Maryland, Nebraska, New Jersey, North Carolina, Oklahoma, Pennsylvania, South Carolina and Virginia) have outlawed the sale of synthetic urine or adulterants for the purpose of passing drug tests.
