You’ll probably agree that failing a drug test, especially the out-of-the-blue mouth swab test, is a bad idea.

People who fail a saliva drug test will usually get their you-are-getting-fired meeting with HR the same day.

Well, it turns out that most people who would otherwise fail the saliva test (due to drug use) can beat the cotton swab analysis.

It’s actually pretty easy if you think fast when your boss and a nurse (or lab tech) pull you aside…

… and if you are courageous enough to serve them an excuse to go to the toilet (for less than 5 minutes).

If you can go to the toilet (with special something in your pocket), you have every chance to pass the mouth swab test safely. What’s that special something?

Mouth swab drug test hack No. 1 – Neutralizing gum.

Another way to pass a drug test is by using mouthwash. However, a detox mouthwash is not nearly as effective as a neutralizing gum. We’ll go through mouthwash vs. gum, but speaking overall, the gum is the safe bet.

A Thing Or Two About Saliva Drug Tests

It’s basically cotton swab drug tests; usually, a nurse takes your saliva with a cotton swab and it goes on to be tested for various drugs. That’s why it is important to know how to pass a mouth swab drug test quickly (cause nobody’s going to wait for you to detox).

A nurse collects your saliva within 5 minutes of seeing you. Excuse yourself and go to the toilet with detox mouthwash, or even better, the neutralizing gum.

From all the drug tests, the mouth swab one is the most difficult to pass. Here are quick guidelines on how to pass various drug tests:

Drug Tests And How To Pass Them
  • Urine drug test – THC detox (slow) or Synthetic Urine (quick).
  • Hair drug test – Detox Shampoo (with purifier).
  • Blood drug test – well, unfortunately, there is no tricking that one. ‘Just don’t do drugs’ solution.
  • Saliva drug test – Neutralizing Gum or Mouthwash (gum is better, but mouthwash is cheaper).

People who are not using drugs such as marijuana should not be worried at all. However, you’re probably here because you belong to a group that might get a cotton swab in your mouth in the near future and should be concerned that the test will be positive.

I would like to say there are no worries; how to pass a saliva drug test in 2018 is a pretty straightforward use-1-min-rinse THC mouthwash. Unfortunately, it is a bit more complicated.

How long after the last use of THC (joint, blunt, brownie, whatever) can saliva drug test detect it?


The consensus is somewhere between 12 and 24 hours (opinions vary even up to 4 days).

However, there is a catch – saliva drug test can be executed immediately. That’s right, you usually don’t get a 5-day notice someone is going to test your saliva for THC. They just walk up to your work desk and do a mouth swab drug test here and there. So, if you enjoyed marijuana anytime the last 24 hours, you might be in serious problems.

Mouthwash vs. Gum – 2 Ways To Pass In Less Than 5 Minutes

To pass a mouth swab drug test, there are only two options – mouthwash and gum. Both of them have really good results – checked with saliva drug test kits.

Here is a quick comparison. Basically, the gum is safer but also pricier. However, failing a saliva drug test is not something that we can afford – but judge for yourself:

I’ll go through the following points and hopefully you’ll be ready when the cotton swab lady comes your way. Here is how to prepare yourself for a saliva drug test – I’ll write about:

Saliva Drug Test – First Lets Get Facts Straight

Saliva testing (using oral fluids) is not a new technique. It has been used for decades in medicine. However, in the last couple of years, saliva drug tests started to be used by employers to check the drug habits of their future or current employees.

Most of us have done some kind of urine (drug) test before or during the employment (I hope nobody needs to go through the hair follicle drug test – the toughest to pass). That worked out pretty fine for most of the folks because they got a 5- or 10-day advance warning that they’ll be tested. Of course, if you know beforehand you’re going to be tested for drugs, you stay away from marijuana for those days and might even think about doing some kind of THC detox.

This mentality is exactly what companies are betting on when trying to catch drug users. They bank on you expecting to be notified beforehand – and then surprise you by giving you a saliva drug test immediately. That’s why is usually useful how to pass a saliva drug test not in less than 12 hours but in less than 5 minutes.

How Is Your Saliva Collected For Mouth Swab Drug Test?

With the mouth swab drug test you don’t to pee anywhere (that would be awkward even if you’ve got a high cubicle). They just stick a cotton swab in your mouth, take a saliva sample, and put the swab in a test tube for drug testing.

This might sound simple but I can tell you these will probably be the worse 30 seconds of your job-life if you’ve been smoking a day before. Why? Because you can be sure that you will be THC positive and there is pretty much nothing you can do. Or is there?

Of course, you can make a mess. Sometimes you can even excuse yourself and go to the toilet – that’s your one chance right there, we’ll talk about it later.

You might want to try with an excuse that you have a dry mouth. But you know well enough that dry mouth is a common effect of smoking weed. What is more, it won’t convince the nurse who’s there for your sample. She needs to take just a little for a saliva drug test.

Saliva Drug Detection Times – When Do You Have To Be Worried?

As said earlier, marijuana or THC will leave your saliva in 12 to 24 hours. This is, of course, not scientifically tested. In truth, nobody knows for sure. Now that is kind of scary.

It could be worse, though. The sources that indicate 12-24 hours saliva drug detection times give information about the mouth swab drug test detection time for other drugs such as cocaine, meth,  and, well, alcohol. I’ve gathered the saliva test detection times in the graph:

As you see, marijuana users don’t have to worry as much as meth and extasy users. These two drugs can be detected in the saliva 3 full days after the use. Cocaine is around 1 full day, while marijuana’s average elimination time (this means that is no more detected by saliva drug test) is 0.75 days or 18 hours.

Again, I have to warn that opinions on how long does marijuana stay in the human saliva differ substantially from a dozen hours up to 4 days. If you have some valid opinion on this, please do help us all out and share it in the comments.

Saliva Drug Test Vs Urine Drug Test

How come companies are starting to use more and more saliva drug tests instead of the standard urine test?

Mouth swab drug test vs urine drug test does make for a good discussion. However, there are a few very clear reasons why companies are doing more and more saliva drug tests on their employees. Here is why:

  1. A mouth swab drug test is cheaper. Yeah, guess what, companies are all crazy about cutting expenses.
  2. Drug testing based on saliva is simpler and quicker. That speaks to the corporate spirits.
  3. A saliva test can detect lower concentrations of THC.
  4. BIG ONE: Saliva drug test catch more people! And we have scientific proof for it.

It might sound intuitive that the cotton swab test will catch more drug users since the swab is immediately pushed into your mouth whereas you have to go to the doctor’s office for a urine test (make an appointment in next 10 days, for example).

Don’t take just my word for it. Journal of Analytical Toxicology has published a comparative study of how many people are caught with saliva drug test (oral fluid drug test) vs how many people are caught with a urine drug test. Here is the full article and the results:

More than 3 out of 100 people who took the saliva drug test, tested positive for marijuana (THC). Less than 2 with a urine test.  Source: Journal of Analytical Toxicology, Vol. 25, November/December 2002

If you’re a company HR executive, you see that it is clear that oral fluid test (saliva drug test) is more thorough. Add that it is cheap and quick, and you’ll understand why the shift towards mouth swab drug test as opposed to the standard urine drug test.

So, this game is a bit rigged against drug users – let’s try to turn the tables:

How To Pass A Saliva Drug Test?

This is really what it comes down to. There is no hiding or escaping for a saliva drug test. Chances are, with the cotton swab technique growing in popularity, every one of us will eventually have to face a nurse who is going to take our saliva sample, no questions asked.
The first idea is to clean your teeth really really good. Well, even if you had the time to do that, it wouldn’t do you much good, I can promise you that.
The only thing you’ve got going for you is an ’emergency trip to the toilet’. When the friendly nurse comes in swinging her cotton swabs with a tail of HR people, you can either:
a) Take the test right away. If you’ve smoked yesterday evening, you know what the result is going to be.
b) Immediately excuse yourself and go directly to the toilet.

Your One Chance To Pass A Cotton Swab Drug Test

I don’t know about you, but I would choose option b) every time. How to convince them you really have to go to the bathroom (and cover-up you’re going to prepare your mouth for cotton swab sampling)? Say your d*ick is going to explode. Say you have such a bad case of diarrhea that you’re gonna sh*t all over the office if they don’t let you.
The bottom line is to GET TO THAT TOILET no matter the cost. What is the worst they can do to you? Fire you for going to the bathroom? You probably know pretty well that’s what they will do anyway if you test positive.
This is your one chance. I can’t repeat enough how important it is for you not to freeze in that moment. Ok, now that you’re in the bathroom where you have previously:
  • Hidden your ‘how to pass a saliva drug test’ product, or
  • You have it on you (in your pocket, pants, whatever)

Here is how this story goes…

How Mickey Mouse Lost His Job (And Worse)

So, about products that can help you pass a saliva drug test; you’re probably figured out there are two kinds:

  • Mouthwashes. That was an obvious call.
  • Chewing Gums. No, really. I’m not even kidding.
 Most of them do work (clearing out and detoxing your saliva is actually not that hard), just be smart about it. For example, here is Mickey Mouse who wasn’t that smart and went buying just some random Ultra Kleen mouthwash:
He’s right, you know. Abstinence is the key, but hey, that’s not as fun as getting high. I feel for Mickey though.
Here’s another review example for the same product:
Yes. These things really happen in real life. Anna didn’t get the job and Zach might even go back to prison! Please do consider thoroughly about which product you choose for passing a saliva drug test.
Here are some good choices that people actually have good experience with and it worked out pretty well in most cases:

Best Mouthwash To Pass A Saliva Drug Test

You’ve got all kinds of mouthwashes out there. I myself would really go for the most reviewed and recommended one. Toxin Rid mouthwash pretty much falls in that category (and Toxin Rid line detoxes are usually the best to pass a urine drug test). Here is how the mouthwash looks like:

Toxin Rid mouthwash is one of the best to pass a drug test. You can get it here.

Here is one review that sold me. Short and to the point:


I’ve looked around a bit and there are pretty much the same mouthwashes for passing a saliva drug test out there. This one is the most recommended and it’s the cheapest. Currently, it stands at less than $30. Considering how much many other ‘how to pass a saliva drug test’ mouthwashes cost, this is definitely a bargain.

Oh, and it works in 1 minute. That will do, I think. No one will ask you why you’ve been in the toilet for 1 minute. If the package said ‘works in 30 minutes’ I would worry about how to explain to them why I was in there for half an hour. Very strong diarrhea comes to mind.

Joking aside, I see one problem with this mouthwash – it is BIG! I can’t imagine hiding that in my pocket when going to the bathroom. With the mouthwash, you really have to place it somewhere in the bathroom, and finding a place where nobody will notice could be pretty tricky.

There is, however, another option you can use – Gums:

Best Way To Pass A Mouth Swab Drug Test Are Actually Gums

As you might have figured out yourself, mouthwashes are big and clumsy. This is not exactly what you need when trying to outmaneuver medical stuff and HR representatives when they come to make a saliva drug test on you.

Gums for saliva drug tests are much more subtle and small (pocket-size). .No one will question you why do you have a gum in your pocket; in fact, most people don’t even notice you have a gum in your pocket anyway.

There are not a lot of saliva neutralizing gums out there – and they are expensive – but considering the risks of not passing a mouth swab drug test, many marijuana users do find it worth the money.

If you want to pass (the inevitable) a saliva drug test, OralClear gum is your best bet. You can get it here.

Here are some quick directions on how to take it. Two important notes – it works in 30 seconds and it lasts for 30 minutes. You have to get the nurse to sticks that cotton swab in your mouth within 30 minutes of coming out of the toilet.


Step-By-Step Of How To Pass A Cotton Swab Drug Test (With Confidence)

Here is the step-by-step realistic scenario of what happens:

  1. The nurse and HR rep comes to your desk/workplace. ‘Yeah, I’m gonna have to take a sample of your saliva and test it for drugs.’
  2. You respond immediately with ‘Sure, just a bit, I’ve been dying to get to the toilet for the past two hours. I’ll be right back’. Stand up, spy-like pick your saliva neutralizing chewing gum that you’ve prepared at the strategic location, and walk to the bathroom. They might allow you outright or you’ll just leave them speechless.
  3. Lock yourself in a stall and start chewing. You might even pee to be more credible (optional).
  4. Come back to your desk/workplace and let them do the cotton swab thing on you.

RESULT: You test negative for all drugs, no matter how much you smoked last night.

How can you know you’ll definitely pass the test:

BONUS: Get A Saliva Testing Kit Yourself And Test Yourself After Using Drugs

If you tend to be skeptical about things, better make sure that the chewing gums clear the drugs out of your saliva yourself.

It’s actually really simple. You can get a saliva drug test at a local pharmacy or just order it over Amazon – you have a picture of how it looks like here, and it tests for 6 different drugs, including marijuana and meth.

This is a step-by-step how to make absolutely sure that you will pass a mouth swab drug test:

  1. You need some saliva neutralizing gums (seen above) and a saliva drug test.
  2. Use some. (I don’t want to tell you to do drugs; quite the opposite, but I guess you know what to do for testing purposes).
  3. About 12-24h after the last use, unwrap the gum and start chewing for 30 seconds or more.
  4. Take a sample of your saliva with the saliva drug testing kit (you get a cotton swab and everything), and wait for the results (these kits work like pregnancy tests, its dead easy to use).

If you’ve chewed for more than 30 seconds, you’ll see that you tested negative on marijuana (THC), meth, ecstasy, etc.. Congrats!

I’ve honestly never met anyone that would be THC positive after chewing the neutralizing gum. It is very effective according to Alive Directory. What I think is the most important is that people can actually test themselves and see with their own eyes how effective it is. Why?

It’s much easier to run away from the HR to the toilet when you know for sure that chewing gum will work. You tested it by yourself and you can better keep yourself together and be calm in the whole situation. Believe me, keeping calm is very important as well – a nut who runs to the toilet drenched in sweat and with 200 heart rate because he’s not totally sure that he’ll come back THC negative and pass the test can be suspicious to the HR.

You can buy the OralClear gums here.

Good Luck!

I’m hopeful these measures are just temporary and we’ll all do what they did in Colorado with the legalization. However, with the laws as they are today, we all have to stuck with the reality of things and have to pass these drugs tests just to keep our jobs.

Fortunately, we have a solution for the saliva drug test. I hope this helped someone to be less nervous about mouth swab tests because you can actually do something about it.
