How To Clean Your System For A Drug Test (Proven Tips 2018)

It doesn’t matter where you live in the world, being a legitimate marijuana smoker can mostly cause you legal issues.

But particularly in United States of America, you do stand a big chance of getting persecuted through a drug test, even though you are legally smoking cannabis. That’s because the widespread employment of drug testing makes the percentage chance higher.

This crazy situation means that many of you will be wondering how to get weed out of your system fast. When it comes to securing a job, or keeping a job, why on earth should you be persecuted through a failed drug test, when in all honesty you completely fit to work and have done nothing illegal?

So learning how to clean your system for a drug test, could be crucial to your financial survival and quality of life. Which is why this comprehensive guide on teaching you how to pass a drug test has been put together.

We’re going to cover every area around drug testing. We are going to talk about issues with the legal system, how long drugs stay in your system, what methods and products work to clean out your system, and what doesn’t.

We will also cover all so that you can be fully prepared the different types of drug test you might face. They really could be nothing to fear, so let’s get started.

The Legal Problems With Cannabis In The USA

Most of you reading this are probably in United States of America, which is why I’ve put this section first. If you not, you can read on out of interest or skip to the next section.

The USA presents some almost unique legal issues when it comes to drug testing.

Firstly, civilian drug testing is more widespread in the USA than any other country on earth. It’s become a major industry, and most companies cover their backsides by screening new employees and reserving the right to drug test existing employees under certain situations.

The problem with that is a perfectly sober person could test positive for having active ingredients, for example THC in cannabis, present in their body, even though they haven’t taken the drug for ages.

The only is this unfair, but it also means that people who responsibly use cannabis and then turn up for work completely free of the effects are living in fear. The second problem is the two tier legal system in the USA.

Eight states so far have legalized cannabis use. The latest was California at the time of writing this at the beginning of 2018.

The problem is that each state has different laws around how much you can possess, where you can smoke it and whether you can sell/buy it. Different states have different laws on legally selling cannabis on licensed premises, taxes on legal cannabis, whether cannabis sales are completely outlawed, whether you can have cannabis plants, it goes on and on.

And even if you smoke completely legally, there is the other huge problem of federal law.

The bottom line is that even though cannabis is being legalized the state level, it still remains illegal to possess, smoke or sell under federal law. So you could smoke cannabis completely legally in your state, fail a drug test and be fired and not have a leg to stand on legally.

If you appeal through the courts, the defense for the big company with lots of money will merely point to its legal status under federal law and the chances are you will fail.

Which means that if you are a cannabis smoker, or you take any sort of drugs, and you work, or on probation, or going through the courts, then you need to learn how to pass a drug test.

It doesn’t matter if you are responsible and never turn up under the influence of drugs to your employment, you’re still at risk, which is why this is so important.

The Facts About How Long Drugs Stay In Your Body

The first key piece of information you need to learn is to understand how long traces of drugs stay in your body, and can therefore be detectable through a drug test.

Different drugs have different detection timescales, and those timescales will vary depending on the frequency of use, how much you take, your general lifestyle and health, and your natural metabolism.

It’s a bit of a minefield, which is why you need is to educate yourself on how to clean your system for a drug test so you can play safe.

In terms of the main drug we are discussing, marijuana, what happens is that the active ingredient in it, THC (the bit which gives you the high) is what a drug test looks for.

When THC hits your liver it is then metabolized into THC-COOH, which is also something most lab drug tests look for.

The problem in giving you a timescale for THC, or cocaine, or anything else to be cleared from your body, is that these factors affect how long it takes:

  • The amount you take
  • The frequency that you take the drug
  • The purity and quality of the drug
  • Your weight and body fat levels
  • Your metabolism
  • Diet, exercise and liquid intake

So as you can see, with all those factors to take into account, there’s no easy answer on timescales and it’s always best to play it safe.

But we can come to some general conclusions based on science and experience, so let’s take a look at each type of drug test and how you can naturally pass it.

labcorp urine test

The Four Types Of Drug Test Out There

There are four types of drug test you could face. These are:

  • Urine test
  • Saliva (swab) test
  • Blood test
  • Hair test

By far the most common is the urine test, so let’s cover that first.

  1. Drug detection times in a urine test

75% of the drug tests carried out in the United States each year are urine tests, so this is the important one you need to pay attention to.

In terms of THC, the metabolites in marijuana, you are looking at an average detection time of around 10-14 days in urine. This applies if you are an occasional user, by which we mean maybe twice a week.

If you are a heavy smoker, or are smoking one of the more modern types of weed that is far stronger, then you are looking at a longer detection time. This could be up to 20-30 days. Very, very occasionally THC for heavy users is detectable for up to 5 weeks after last smoking.

So as a weed smoker you need to understand that the more you smoke, the longer it will be detectable, which is not in common with other drugs, where they tend to leave the system in around the same time no matter how much you consume.

In terms of other drugs, amphetamine, cocaine and metamphetamine can be detected for up to 5 days.  LSD, psilocybin, heroin and opiates can be detected for up to 5 days, and benzodiazepines (like Valium) for up to 30 days (it depends on so many factors).

Urine sample

  1. Drug detection time in saliva

There is better news if you are facing a saliva drug test, where a mouth swab is taken and tested.

It doesn’t matter what the drug you take, it will be undetectable in your saliva within 48-72 hours (opiates take around 24 hours). The slight exception to this is PCP which can take up to 3-4 days.

The great news if you are a weed smoker is that it’s undetectable in saliva in as little as 3 days, so if you have the luxury of a 72 hour wait, then you can be certain of passing a swab test.

  1. Drug detection time in blood

You are very unlikely to face a blood drug test. They are more expensive to undertake. They are very accurate, as they look for the specific drug, rather than metabolites or by-products.

Because they can only be administered by a healthcare professional, you will know well in advance if you are facing a blood drug test. In terms of detection times, most drugs are undetectable in blood within about 72 hours.

The bad news however is there is an exception, and it’s marijuana. If you are a chronic user, basically daily, then you will not be clear of  THC metabolites for a least five days, in extreme cases it can be present up to 2 weeks!

  1. Drug detection time in hair

It doesn’t matter what drug you take, it can be detectable in hair for as long as the hair is on your head. But only in hair that has grown clear of the follicles by a certain distance.

Basically, a sample is taken from the head to cover 90 days of use. That’s the standard length of hair, and stand the detection time for every type of hair test and every drug that is looked for.

So it doesn’t matter if you smoke weed 1 million times a day, or if you snort cocaine 10 times day, if you’ve done in the past 90 days then it will be found in a hair drug test.

The good news is that hair drug tests are usually only done for court or law enforcement purposes, never in my experience for employment.

Unsupervised V’s Supervised Lab Tests

When it comes to taking a drug test, a key part of learning how to pass a drug test every time is to know in advance if the drug test is to be unsupervised or supervised.

This is a key difference which will allow you to prepare a strategy for the countermeasures you deploy to get through the drug test.

An unsupervised drug test is a urine test. That’s obvious, because you can’t submit a hair, blood or saliva sample unsupervised, somebody has to take it from you.

But in terms of an unsupervised urine sample test, you go into a room on your own, or behind a screen and submit the sample in a plastic container. So the key point here is that you are not observed.

If it is a supervised test you have to be prepared to be observed. This doesn’t mean that you they are literally going to look at your penis or lady bits as you piss (although they could be), but somebody is going to be in the room observing you generally to make sure that you are not submitting a fake sample.

How To Clean Your System For A drug Test

It’s important to understand what we mean by learning how to clean your system for a drug test.

The truth is that the only way you can clean your system for a drug test is to do a natural detox. Yes you can speed this up with certain products, but you have to let nature take its course. This takes time you might not have.

Any other talk of cleansing your system in any amount of time shorter than your body can do on its own, is really around either masking the toxins or submitting a fake sample the doesn’t contain toxins in the first place.

The key point to make is that you can only mask toxins in a urine or saliva drug test. You can possibly wash out toxins from your hair, which we will discuss later.

So now we understand that the only way to pass a urine drug test, unless you stay clean for a couple of weeks, is to mask the toxins or submit a fake sample, let’s discuss how you can do both of those things.

Best Way To Pass  Drug Test On Short Notice: Synthetic Urine

If it’s an unsupervised urine drug test, then you’re laughing. The best way to pass a drug test on short notice with minimal risk is to use fake urine.

What you will need is some high quality synthetic urine that has all the characteristics needed to pass a lab drug test:

  • Tools to submit at the right temperature
  • Contains uric acid
  • Contains urea
  • Contains the 11 distinct chemical compounds found in real urine

Only two brands have these capabilities, Sub Solution and Quick Fix 6.2. Either of these are a good option.

They contain all the right compounds, and have the ability to be heated up to the temperature that human urine is excreted from the body (around 95 degrees Fahrenheit).

Either option is good, but one contains a heat pad that keeps the urine at the correct temperature, while the other has special heating powder which reacts to create heat in the fake urine.

If it’s unsupervised then all you have to do is strap it on to your body and submit the sample into the supply container. If it’s unsupervised you also get the luxury of being able to look at the thermometer you can stick to the side of the fake urine sample to make sure it’s at the right temperature.

If its a supervised drug test then you going to need some confidence to carry out submitting a fake sample.

You can either take the risk and strap the sample on your body and submit it through a plastic hose, simply by twisting a tap at the end. This is great, unless the lab technician catches sight of what you’re doing, so it’s not amazingly safe.

The other option is to use a fake penis. The “Monkey Dong” is one such option. It literally looks like a penis, so that even if you are caught sight of, unless somebody takes a really good look then you should get away with it.

If you are female, then this is not such a big issue as you have to sit down to submit the sample, or least squat which gives you more options to hide a plastic hose and tap.

Using A Detox Drink To Pass a Urine Drug Test

Let’s say upfront the one of the big misconceptions about detox drinks is that they don’t actually clean your system for the drug test They don’t flush the toxins out and leave you free to take a drug test any time you want.

What a detox drink does is to temporarily mask the toxins, by cleansing your urine for a small window, usually a few hours. Just as with fake urine samples, you need to spend a lot of money on a detox drink that will actually work.

There are some out there which are literally just flavored and colored water, and are utterly useless. So ignore the cheap prices, big promises and bright bottles, you are going to need quality if you are going to use a detox drink to pass a drug test.

There are lots of brands out there which are risky, things like Qcarbo32. If you want to remove most of the risk, you should really only be looking at using Rescue Cleanse or Mega Clean.

Neither of these are cheap, around $50 or more, but they stand the best chance of working.

You can order Rescue Cleanse from the manufacturer’s website.

It’s important to point out that no detox drink is risk-free, but they can dramatically increase your chances of passing a drug test. But if you weigh 200lb or less, and aren’t crazy smoker or user, then a 32oz bottle of either will probably work.

For more info check out my detailed review of detox drinks.

Never buy from Amazon, always buy detox drinks from a reputable specialist seller.

Whichever brand you choose, it’s essential you follow the instructions closely. You also need to understand very clearly that they only create a short window of opportunity, usually around five hours where you will have toxin-free urine.

How To Get Weed Out Of Your System Fast: Drug Detox Pills

Another option you have is to use detox pills to pass either a supervised or unsupervised urine drug test.

If you want to learn how to get weed out of your system, then they are definitely a legitimate option to consider, but only if you choose high quality detox pills.

But we are not talking about just using detox pills to pass a drug test. There aren’t really any detox pills out there that work in less than five days, and any that claim they can are usually undertaking false advertising.

What you have to do is combine detox pills with a detox drink to increase your chances of producing a metabolite free sample.

For example, Mega Clean comes with six pre-rid tablets that you take prior to the drink.

You can only get these if you buy the detox drink from a reputable seller, so never buy it without them, it’s a big risk.

The only pills I would recommend are Toxin Rid. They can work on their own, but the absolute best strategy is to have a seven-day plan prior to the test where you consume the pills, and then on the day of your test use a detox drink as well.

That way you are minimizing the toxins in your body, and then on the day of the test ensuring that those lesser quantity of toxins stand a greater chance of not appearing in your urine sample.

How To Pass A Hair Follicle Drug Test

Because of its reliability, the hair follicle test is the second most common type of drug test in the USA, but still only in a minority of circumstances. Unfortunately it’s also becoming more common because of that reliability, due to the difficulty in getting rid of toxins from your hair.

It’s more expensive, but it allows an employer, court or law-enforcement agency to get a 90 day snapshot of your potential substance history.

It’s far more invasive, and it makes me sick that they do it because you could have taken something 89 days ago and still be penalized for it, but that is the reality we are in.

There is no way to mask the toxins to pass a hair follicle drug test. The only option you have is to literally scrub out the toxins to leave the hair sample clean.

Let’s say upfront here that most detox shampoos are complete bullshit. A lot of them are either fake, normal shampoo or make big claims based on the ingredients that they cannot deliver. If you’re looking for a certainty, there are very few brands out there, and the one you will read about most is called Aloe Rid.

The reason that Aloe Rid has such a great reputation is that it contains Propylene Glycol, which is incredibly powerful at stripping impurities out of the hair.

But you have to look for the old formula Aloe Rid. The new formula doesn’t contain that active ingredient because it proved to be too powerful and potentially damaging. But let me assure you, that if you use it several times a day in the seven days leading up to a hair follicle drug test, then you stand a great chance of completely removing the toxins from your hair.

But the old formula Aloe Rid is becoming less common because it’s not made any more, and you are going to be paying anywhere up to $200 for a bottle.

The old, original version of Aloe Rid (with new name and design) is still available on Testclear in a combo pack with Zydot Ultra clean detox shampoo (what is one of the main ingredient of the macujo method).

On top of that, using Aloe Rid on its own is not a guarantee of clearing your hair of toxins, so if your job or freedom depends on it, how can you strip your hair of toxins to pass a hair drug test?

Zydot Ultra clean drug test shampoo

Pass A Hair Follicle Test: The Macujo Method

The only really reliable way you can strip your hair of toxins to pass a hair follicle drug test is to use what is known across the Internet as the Macujo method.

There are other “methods” out there, but this is the only one which has a track record of working since it appeared online somewhere around 2002.

The Macujo method uses a combination of the following ingredients:

  • Nexus Aloe Rid shampoo (“Old Style Aloe Toxin Rid)
  • Clean & Clear pink
  • Vinegar (usually Heinz is recommended but it doesn’t really matter)
  • Tide liquid detergent
  • Zydot Ultra Clean Shampoo

It’s an invasive process which takes about an hour each time, can burn your scalp, wreck your hair if you’re not careful, and uses a lot of water.

You also need to do it every day in the few days leading up to your test, but it’s worth it if you pass a drug test.

How it works is the combination of ingredients first damages the hair cuticles (layers that cover the hair cortex), creating gaps in them. Then the toxins are cleaned out of the hair cuticles and cortex.

As long as you do it properly and condition there afterwards, and don’t do anything dumb like blow drying it, then you shouldn’t see your hair falling out.

If you know you have toxins in your hair, basically you have taken any drug in the past 90 days, then this is the only method that stands a chance of working, and the only one you should consider.

Passing A Saliva/Mouth Swab Drug Test

Variously referred to as a saliva drug test, mouth swab drug test, or sometimes a cheek swab drug test, it’s all the same thing where a cotton bud is used to take a sample of saliva from inside your mouth, usually from an area of the mouth where you don’t have running saliva, and are more likely to retain toxins.

It’s non-invasive, which means it is popular for quick on the spot testing by a non-medical person.

This means your boss, or personnel department can simply take a swab on the spot and then place the sample on a multi panel drug test kit to get the result.

If you haven’t taken anything, or smoked, in the past three days, then you will be fine. But anything less than that and you could be in trouble.

But there are ways to pass a saliva drug test by deploying quick countermeasures.  Whether you are told in advance about a saliva drug test, or it’s going to be administered on the spot, you do stand a chance using one of two methods

Oral clear gum

1.Use an oral saliva cleansing chewing gum.

There are specialist toxin cleansing chewing gums out there, like Oral Clear, which can cleanse your mouth of all toxins in a few seconds.

This effect will last around 30 minutes, giving you a small window of opportunity. Because these gums are very small, you can carry one on you, and if our asked to take a test, as soon as eyes are turned away, put the gum in your mouth and start chewing. In 20 seconds you will be clear.

Gum is great whatever the circumstances, for example a roadside test. The bottom line is that most people don’t know about saliva cleansing gums, and because it’s so easy to take them, people will just think it’s normal chewing gum.

Even if they are suspicious, if you’ve got no packaging on you, all they have got is a lump of gum, which proves nothing. The only downside is the price, one piece of gum costs 90$.

2.Use a mouthwash.

There are specialist mouthwashes as well, like Toxin Rid rescue wash. They come in very small bottles that you can carry on you, and as long as you are not seen taking them, you just wash your mouth for a few seconds in a toilet cubicle prior to the test to give yourself a clear window of around 30 minutes.

How To Pass A Blood Sample Drug Test

If you are unlucky enough to be a told you need to take a blood sample drug test, then there is no way you can submit a fake sample for obvious reasons.

The great news is you are unlikely to face a blood drug test under any normal circumstances. This is because it requires a specialized person to take a sample, and it has to be done under specific conditions.

On top of that, drugs don’t actually stay in the bloodstream for very long, so it’s not hugely reliable method.

But where it is more reliable than other methods is that it looks for the actual drug itself, rather than metabolites, therefore eliminating false positives. So in some circumstances it will be employed.

As you already know, all drugs apart from marijuana leave the bloodstream in three days or less, and marijuana is undetectable after about five days, so if you haven’t taken anything for a week then you will be fine.

If you only have a week before a blood drug test, the only real option you have is to speed up natural detoxification of the body.

The only way you can really do this, that is recommended, is to use Toxin Rid detox pills to speed up the process.

A seven day detox course will help to increase the rate at which your body flushes out toxins from its cells.

Combining detox pills with increased amounts of water consumption, eating a healthy diet and taking gentle exercise can all help the body to become more efficient at getting rid of toxins.

How to pass a blood drug test

Can A Natural Detox Work?

We have just spoken about taking a seven-day detox supported by detox pills prior to having a blood sample drug test.

But whatever type of drug test you are facing, can a completely natural detox work?

You will read lots on the Internet about how you can speed up a completely natural detox. You will read about natural supplements you can take to boost things.

The bottom line is that apart from taking something of high quality like Toxin Rid to increase the rate at which your body flushes out toxins in the short term, if you go down the completely natural route, there’s nothing you can do to speed up the rate at which this happens.

The reason for this is simple: evolution. Our bodies have had hundreds of thousands of years to develop the optimum method of expelling things we don’t need or want from our bodies. There are no miracle home remedies for drug test.

You can give your body the best chance of working at peak performance by eating healthily, taking exercise, taking on plenty of fluids, and of course abstaining from drugs and putting other toxins into your body like alcohol or nicotine.

But other than that, you can’t really speed up the natural process beyond the rate at which it naturally works.

So the bottom line here is that if you have 30 days before a drug test, then sure, go for an all natural detox.

To completely clear your system for a drug test,you’ll have to:

  • Stop smoking weed, or taking drugs
  • Live a healthy lifestyle
  • Eat clean, lots of veggies and fiber rich foods, no junk food
  • Drink plenty of water
  • Exercise regularly

But you will be 99% sure of passing at the end of that time, unless of course it’s a hair drug test.

Internet Myths  And Natural Home Remedies For Drug Test That Won’t Work

When you’re up for a drug test, and you know you will f

ail, then you need to learn how to get weed out of your system fast.

It’s the same with any drug is well, if you are up for a drug test and desperate you will be on the Internet trying to find out how to clean your system for a drug test.

But the problem is that there are lots of people out there who will tell you how to pass a drug test, but using the product sales selling. They will make big claims while playing down other products and methods.

That’s marketing, and most of it is completely false.

On top of that, you will get the Chinese whispers, crazies, and people who got lucky muddying the waters, telling you about these weird and wonderful ways that they managed to flush out their system and pass any type of drug test.

In terms of countering the worst of these myths:

  • Niacin
  • Submitting your friend’s urine
  • Natural Detox Drinks
  • Certo
  • Drinking Vinegar

 Niacin is dangerous and definitely doesn’t work.

Submitting your friends urine instead of your own is pointless.

Apart from having to take your friends word for it that their sample is clean, unless you pre-test it just before you go, you’ve also got to get their sample just a few hours before your own test, and then keep it at body temperature.

There is a high risk it will be spoilt, and real urine starts to display signs of age in just a few hours.

If you try to add something to the sample you submit at the time, you are going to fail. If it was as simple as pouring ammonia in the sample for example, everyone would do it and there would be no industry around beating drug testing. Also, credit the billion-dollar lab drug testing industry with some scientific intelligence, please.

Drinking any sort of magic natural substance, like various teas, fruit pectin (certo method), all that stuff. None of it works.

I say that with some reservation, because there is evidence that the fruit pectin method does work in some cases, because the pectin can potentially coat the lining of the bladder and temporarily prevent metabolites entering the urine.

But scientifically there is nothing that proves this and relying on it alone is basically nuts.

Drinking vinegar will not work.It tastes disgusting, and in large volumes the acid can be damaging. This is the case with pickle juice, and any other method which claims that acid will help to get rid of toxins.

Any method which claims you can detoxify your body in 24 hours and pass a drugs test is false. The only thing you can do with so little time before a drug test is to mask the toxins.

Learning How To Pass A Drug Test: Summing Up

I hope this guide to learning how to get weed out of your system fast, or clean your system for a drug test of any type, and after taking any drug, has been of help.

The bottom line is that if you ignore the crap advice, understand how long drugs can stay in your system, and use the things that really can work, then you can pass any type of drug test.

But you need the right tools, you need to know the countermeasures you can take, and you need the time it will take to succeed.

So yes the drug laws in the USA and elsewhere are unfair, but by educating yourself and getting smart, you can be one of those people who doesn’t live in fear of getting that letter, or breaking out in a sweat every time their boss walks up to them.

Frequently Asked Questions About Drug Testing

What is a non dot drug test?

A dot drug test, standing for Department of Transport, is usually a five panel drug test that is mandatory for people in federal agencies governed by the Department of Transport. A non-dot drug test is a non-mandatory drug test that companies can implement on their own, even if they are governed by the Department of Transport.

How long does acid stay in your system?

Different studies suggest acid stays in your system for slightly differing lengths of time, which is why people get confused. But on average, it appears that LSD is often undetectable in blood within as few as a handful of hours, and usually after 12 hours, and it’s often undetectable in urine within 24 hours, and definitely within three days. You should however be aware that a frequent user with an unusual body type or metabolism could still have signs of LSD use their urine for up to a week.

How long does ecstasy stay in your system?

The average time that ecstasy (MDMA) stays in your system to be detectable through a drug test is around 1-2 days in the blood, and up to 4 days in urine. As with most drugs though it will depend on the user, the quality of what was taken, the amount of what was taken, and if the user topped up in more than one dose. Some people report traces of ecstasy still detectable in urine after seven days, but this is an exception.

How long does tramadol stay in your system?

Tramadol will potentially show up in urine screening for up to 4 days, with the usual average being around two days. Four days would be unusual, and only chronic users tends to still display signs of usage after that length of time. For most normal doses and situations, a user will be undetectable within 48 hours.

How long do shrooms stay in your system?

The active ingredient in magic mushrooms, psylocybin, is not fat-soluble, so it gets flushed out of the body through urination quite quickly and doesn’t hang around in the body cells in the way some other metabolites do. Usually in a saliva or blood test it will be undetectable within 24 hours, and in a urine test within 48 hours. However these times can be extended depending on the person and the dosage. It is generally recommended to allow five days before submitting a sample to be certain of being clear of the metabolites.

How long does adderall stay in your system?

Adderall is usually detectable in blood up to 24 hours, and in urine for up to 72 hours. Sometimes this can be longer depending on the type of person and dose, however for most people 72 hours is the maximum.

What can cause a false positive on a drug test?

Ritalin, a common ADHD drug, is one of the biggest culprits of false positives in drug tests, being guilty of false positives for amphetamine, methamphetamine and LSD. Similarly, Doxylamine, a common ingredient in some over-the-counter sleeping pills, can give false positives for methadone, PCP and opiates. If you are using either of these legitimately, then you should always notify the lab before undertaking a drug test.

How to cover the smell of weed?

Depending on the circumstances, you can cover the smell of weed by keeping it in an airtight container rather than leaving it laying around. When you are smoking, you can cover up the smell by using a vaporizer or what is known as a “doob tube”, which filters the smell so it smells like laundry. If you smoke indoors at home then a great way of covering up the smell is to invest in a good quality air purifying system. In terms of personal hygiene, showering, brushing teeth, deodorant, perfume, all help to cover up the smell of weed.
