How to Pass a Drug Test — the Ultimate Guide on Getting Clean

How to Pass a Drug Test — the Ultimate Guide on Getting Clean

Whether you are a casual stoner, a regular user, or a bodybuilder in love with steroids, a drug test is probably one of your greatest fears. Of course, simply not using drugs is the best recipe, and quitting them completely would give you a much healthier and more fulfilling life. However, if you are not ready for that yet and are wondering how to pass a drug test without getting clean, you’ve come to the right place.

There are many situations where you can be asked to do a drug test. It may be by your potential employer (drug prevention in the workplace has become very common), an insurance agency official, a parole officer, or even the court. If you want to know how to pass a drug test in any of these situations, there are several factors that you need to consider: how you will be tested, for which drugs, and how to beat that specific kind of test.

How will you be tested?

If you are wondering how to pass a drug test, the first thing you need to know is how you will be tested. That way, you can prepare and create a strategy that will help you fool the test. Here is a list of typical drug tests:

  • Urine test
  • Hair cuticle test
  • Blood test
  • Saliva test
  • Sweat test

All these tests have their advantages and disadvantages and each demands a different kind of preparation. Hopefully, you will know about the test in advance, so you will be able to take all the necessary steps.

Moreover, check your rights and the company policy on drug tests. Maybe you can find some restrictions that will be helpful to you or a loophole that will allow you to choose the type of test. If you can choose the test yourself, pick the one that you can pass easily. For example, if you are a regular marijuana user, go with the urine or hair test, but if you only use drugs sporadically, opt for either a saliva or blood test as they have the lowest detection windows.

Which drugs will you be tested for?

Knowing which drugs you will be tested for is crucial for the preparation and figuring out how to pass a drug test. You can definitely expect tests for the most common illicit drugs, such as marijuana, opioids (morphine, heroin, etc), amphetamines, phencyclidine (PCP), barbiturates (phenobarbital and secobarbital), and cocaine. However, the test may include other illicit drugs, as well as prescription drugs and alcohol.

Depending on the drug you have used, you will make a plan for the test. Drugs such as marijuana and cocaine are detected in different ways compared to steroids, for example.

Keep in mind that, while there are ways to fool these tests, most laboratories have established certain measures to prevent that from happening. Therefore, none of these methods will work 100%, but they will still give you a chance.

How long do the drugs remain in your system?

Finding out how to pass a drug test is no easy feat, which is why you need to be aware of how long the drugs stay in your system.

Some drug traces disappear rather quickly, while others can be detected weeks after you’ve used them. If you want to know how to pass a drug test, you should first learn if the drug is still detectable. To help you figure out if the drugs you use will be found, here is a list of the most common drugs and how long they remain in the system.

  • Barbiturates — 2–10 days
  • Amphetamines — 28 hours
  • Benzodiazepines — 2–3 weeks
  • Cocaine — 2–10 days
  • Heroin — less than 1 day
  • Morphine — 2–3 days
  • LSD — 8 hours
  • Marijuana — casual use, 3–4 days; chronic use, several weeks
  • Methamphetamine — 2–3 days
  • Methadone — 2–3 days
  • Phencyclidine (PCP) — 1 week

It is not just the type and dosage of drugs that define how long the metabolites will remain in your system. Other important factors are your age, sex, weight, ethnicity, as well as various medical conditions.

Passing a drug test 101

While your strategy will depend on the type of the test and drugs you’ve used, there are several things that apply to all drug tests.

The most important of all is very simple: don’t use drugs! The moment you find out about the test, you should stop using all illicit drugs. That way, a test with a short detection window will not find any drug metabolites. In that case, you might get completely clean by the day of the testing, so you won’t have to cheat.

Another way to cleanse your body is to start a detox. First of all, eat lots of greens such as spinach, broccoli, and peas — they will improve your metabolism. Furthermore, drink lots of water, get enough sleep, and start exercising. Finally, cranberries, blueberries and other antioxidants should also have an important place in your diet.

How to pass a urine drug test

Urinalysis is one of the most common types of drug tests. Surely, when you started wondering how to pass a drug test, your first thought was to use someone else’s urine.

Unlike with alcohol, the urine drug test will show rather accurately the presence or absence of illicit or prescription drugs. Drug use leaves drug metabolites in the urine that can be easily detected. The metabolites can remain in the body for as long as 12 weeks after the usage.

The most common, 5-panel test, will examine the urine sample for the presence of the following drugs:

  • THC
  • Cocaine
  • Opiates
  • Phencyclidine (PCP)
  • Amphetamines

However, bear in mind that your employer or parole officer might opt for a test that would identify the presence of other drugs as well.

When it comes to fooling a urine drug test, the most common methods are diluting, substituting, and adulterating the sample.

1. Sample dilution

A diluted specimen is a urine sample that contains an above-average amount of water. Because of all this water, it will be harder to detect the drug metabolites. Even if there are some drug traces found, there will be so little of it that the test will most probably be negative.

Sample dilution is very common and can also happen unintentionally if, for example, a person drinks an excessive amount of liquid before the testing. If you opt for dilution, here is what you need to do.

In the week before the test, drink as much water as you can. It is also important that you eat healthily. Finally, 24 hours before the test, take a vitamin B complex — it will restore the yellow color of your urine and the dilution will be less noticeable.

Another option is to add water directly to your urine sample. However, this is a very risky trick. Most of the testing facilities are aware that the tested people might try to hide the traces of drugs, so they do their best to prevent that. Don’t be surprised if you find blue or green water in the toilet — they dye it so that it would be obvious if someone tried to dilute a sample with it.

Extra tip: When diluting a sample, you must be very careful. You need to add enough water to hide the presence of drugs. However, pay attention not to add too much, as the lab technicians will realize the sample had been tampered with.

2. Sample substitution

Surely, when you started wondering how to pass a drug test, your first thought was to use someone else’s urine. It’s a common movie trope and in film, it seems to work. In truth, this technique does have high success rates, but it can still be risky. If you want to borrow a sample from someone, make sure not to take it from a female friend. Imagine the embarrassment if they not only realized that you’d cheated but also told you that “you” were pregnant.

There are plenty of other ways to find a substitute for your own sample. Synthetic urine and liquid urine are available online. Another option is powdered urine, which you need to mix with water to form urine, but is the easiest to smuggle into the toilet.

Extra tip: Keep the urine sample at the right temperature. If it is too cold or too hot, you’ll get caught.

3. Sample adulteration

Adulterating the sample means adding chemicals to it. These chemicals will either mask the presence of the drug metabolites or mess with the laboratory equipment. Either way, the drugs will fly under the radar.

The most common chemicals are soap, bleach, salt, and eye drops. There are also cleansing drinks that contain such chemicals and are available online.

Nonetheless, if you’re trying to find out how to pass a drug test, keep in mind that this is not a reliable method. The chemicals used for adulteration are easily detectable. Go with adulterating only if you don’t have time for other options.

How to pass a hair drug test

Testing a hair sample for drugs has become a common practice. It is the most accurate test and, therefore, the hardest to fool. Moreover, it can reveal long-term drug use. For example, this test can detect THC metabolites for up to three months.

While your chances of beating this test are low, it is still achievable. Here is how you can do it.

1. Shave it off

This may seem like a hard decision if you like your hair longer or if you think bald won’t look good on you. Still, the hair will grow again sooner or later and this is the safest way to fool the test.

Keep in mind that if you have no facial hair, the technicians will use hair from other parts of your body. Therefore, full body-wax is advised.

2. Home remedies can be helpful

If you decide that going bald is definitely not your thing, you use some stuff that you already have at home. White vinegar will do the trick if you leave it on your hair for some 15 minutes. Other things you can use are a liquid detergent, sea salt, lemon, and baking soda.

Whichever you choose, make sure to rub it in well and keep it on your hair for a while. Also, at the test, they will most probably take a sample from the back of your hair to avoid spoiling your haircut, so focus on that area.

3. Hair detox shampoos

Special shampoos that are designed to get rid of drug metabolites in your hair can be easily found and ordered. Use the shampoo for at least several days to get better results. However, you can never be sure that these shampoos will work and the high-quality ones can be pretty pricey.

How to pass a blood drug test

The blood drug test is your worst enemy. It is incredibly accurate and almost impossible to fool. Fortunately, these tests are not so common. They are expensive and intrusive, must be performed by professional medical staff, and getting the results may take up to one week.

For these reasons, the chances of you having to do a blood test are pretty low. Still, if you are trying to get health insurance or are a part of a legal process, prepare yourself for it.

1. Wait until the drugs disappear from your blood naturally

One of the major flaws of this test is that drugs clear out of your blood pretty quickly. Most drugs won’t be detectable after 48 hours and some drugs, like LSD, will disappear in only 3 hours.

This technique is your biggest chance to pass this drug test. All you have to do is stop using drugs and wait.

2. Detoxification

Detoxing your body can be very helpful in this situation. Eat plenty of healthy food, workout, and drink lots of water. Moreover, you should increase your intake of vitamin C and get enough sleep. This will boost your metabolism and make the drug traces disappear faster.

You can also give detoxification products a try, but bear in mind that they are not reliable. The ingredients can be detected by the lab technicians and you’ll get caught.

How to pass a saliva test

Saliva drug tests are common for several reasons: they’re inexpensive, simple to administer, and the results are available instantly. A simple drug test kit is all the equipment one needs for this test. Therefore, employers usually use it to test job candidates and employees. The tricky part is that, because of its simplicity, your employer might decide to use it randomly, without any warning.

The drugs that can be detected by a saliva drug test are:

  • Marijuana
  • Cocaine
  • Amphetamine
  • Methamphetamine
  • Opiates/Heroin
  • Phencyclidine
  • Benzodiazepines

Just like the blood drug test, saliva test also has a short detection window. Any traces of toxins will disappear in a couple of days, so it’s relatively easy to pass. However, you should take some extra steps just in case.

Of course, you should stop using the drugs before the test. Then, focus on oral hygiene. Brush your teeth meticulously — make sure you clean the cheek area and brush your tongue as well. Using mouthwash will be helpful as well.

Here are some other things you can do to make sure you pass this test:

  • Drink lots of water
  • Eat food high in calories
  • Use chewing gums

How to pass a sweat drug test

Sweat drug tests are relatively new and are seldom used. They are not as accurate as other kinds of tests since different environmental factors can cause the test to be a false positive. However, if you’re wondering how to pass a drug test, you should be prepared for this kind of test, just in case.

To pass a sweat test, you should abstain from any drugs in the days before the testing. Moreover, try to eat healthy food and drink enough fluid. Finally, for this test, you can buy any sort of detox products as the chances of them being detected are quite low.

How to pass a steroid drug test

Steroids have long been banned from sports competitions, yet they are still commonly used. If you are a bodybuilder, a professional athlete, or even a physical worker who needs some extra strength for your job, you’ve probably considered using steroids.

There are many ways to test for steroids, and the most popular are urinalysis, blood test, and hair test. While you can use some of the previously mentioned advice on fooling these tests (for example, urine sample substitution), the analysis is a bit different, so here are some extra tips for this specific type of testing.

1. Increase epitestosterone levels

Steroid usage significantly increases testosterone levels. When analyzing the results of the steroid test, the technicians look for changes in testosterone to epitestosterone ratio. The regular ratio is 1:1. However, many athletes have a naturally higher testosterone level, so you’ll be flagged if the ratio is 6:1 or more.

To make your high level of testosterone less noticeable, you should use oral supplements that will increase the epitestosterone level. This will make the ratio seem normal and you’ll pass the test with flying colors.

2. Diuretics

Diuretics are an effective and fast way to detox your body and eliminate the steroid metabolites. They are also pretty easy to find as you can buy them in any pharmacy or order them online.

If you want to avoid drugs, you can use some of the natural diuretics. The most effective ones are caffeine, uva ursi, dandelion, parsley, hibiscus, and green and black tea.

3. Blood transfusion

If you’re wondering how to pass a drug test and are ready for some more drastic measures, blood transfusion is a good option.

Here is how the so-called “self-donation” process works. You donate several units of blood, which are sent to analysis. Then, the blood is processed in a way that will clear out all the toxins, including the steroid metabolites, and you will receive it back.


Now that you’ve learned how to pass a drug test you are ready to start preparing for it. However, don’t forget there is always a chance you’ll get caught. Therefore, the best way to pass a drug test is not to use drugs at all. Think about it — it will certainly give you a new lease on life.
