What is a Mouth Swab Drug Test?
A mouth swab drug test is a non-invasive and effective method for detecting the presence of drugs or their metabolites using a saliva sample. An employer or tester may collect your sample either by using a swab or testing strips.
Test strips allow for a direct application of the collection pad against the cheek or under the tongue, while a swab involves physically rubbing the inside of the mouth to gather the saliva.
The oral fluid drug test has the most proximate detection period and is the most efficient drug testing method when it comes to identifying short-term abuse.
An employer can also opt for a saliva test during pre-employment drug test, random drug test, return-to-duty testing, and on suspicion (including roadside drug testing).
While many employers are opting for saliva drug test, DOT has approved oral saliva drug testing as a option for transportation employers to identify drug abuse.
What Can A Mouth Swab Drug Test Test For?
The mouth swab drug tests can detect as many as 14 drugs with customized panels. Here are some drugs that a mouth swab drug test can test for
- Marijuana (THC)
- Opiates (Both Natural and Synthetic opiates like fentanyl)
- Amphetamines and Methamphetamines
- Benzodiazepines (Xanax, Valium, Ativan, etc.)
- Phencyclidine (PCP)
- Synthetic Cannabinoids
A mouth swab drug test can detect the drugs within 5 hours to 72 hours after intake. The detection period can vary based on factors such as type or class of drug used, amount, frequency, duration, route of drug administration, metabolism of the individual being tested, and the sensitivity of the testing method.
Here is a general detection window for a saliva drug test.

How Does A Mouth Swab Drug Test Work?
If you're looking for ways to pass a mouth swab drug test, understanding the testing process and results is crucial.
Your mouth swab will be collected by the tester to screen for illicit drugs. The tester may either use a swab or testing strip to collect the sample and conduct a drug test.
Some of the common oral saliva drug testing procedures include
- On-site mouth swab drug test - Employers may use saliva drug testing kits to do a preliminary drug screening.
- Enzyme Immunoassay Technology: The mouth swab drug test primarily uses enzyme immunoassay technology to detect drug metabolites.
- Confirmatory Drug Testing: Liquid Chromatography and Gas Spectrometry are used to confirm positive findings. This is a lab-based oral saliva drug test that gives precise results.
This is how the saliva drug test works
1. Once the kit is placed in your mouth, it absorbs the saliva, and the indicator window turns blue, reminding you that enough sample is collected.
2. Wait for the designated time specified in the instructions, usually a few minutes, for the test to process the saliva sample.
3. If the test shows one or more lines in the T region(s), it indicates a negative result (even if it is a faint line).
4. If no lines appear in the test region(s), it indicates a positive result.
5. The employer may send your drug test sample for confirmatory testing if it occurs positive.
Inconclusive Mouth Swab Drug Test
An inconclusive mouth swab drug test indicates that the test result does not provide definite and clear evidence of drug presence or absence in the saliva sample.
While it is often considered a tampered attempt, it may happen due to various reasons, such as insufficient saliva samples, improper testing procedures, or issues with the testing kit itself.
Inconclusive results can create uncertainty and may require additional testing or retesting.
How to Pass Oral Drug Test in 24 Hours?
If only a few hours are left for the swab test, you can try the following tips though the chances are less likely.
Here are some steps on how to pass a mouth swab drug test for weed and other illegal drugs
- Hydrate - Drinking lots of water throughout the day can help the saliva flow.
- Swish and Rinse - Frequently swish water vigorously around the mouth and rinse.
- Wipe it out - Wiping the mouth, mainly the gums and cheeks, may help get rid of THC traces and reduce the concentration in the oral fluids.
- Detox mouthwash - Use mouthwash without alcohol, else may test positive for alcohol.
- Brushing the metabolites away - Brushing the teeth frequently throughout the day.
- Gums for the Gums - Anti-cavity chewing gum can keep the saliva clean.
- Add Fatty foods - Eat fatty foods like greasy burgers, pizza, fries, etc. Active THC binds with fatty foods and gets absorbed, so there are fewer chances of THC detection in the mouth.
In the worst case, if there is no time to spare and worried about positive results, then adulterants can be a last-minute solution. Adulterants are chemical substances that interfere with drug tests. If the tester suspects adulteration, the test will be considered invalid, and a repeat test will be ordered.
Note:Adulterants can only keep the saliva clean for half an hour. Using mouthwash or drinking lots of water, or taking junk food may reduce the number of metabolites in your saliva, but it might not completely eliminate it.
You may get into trouble if your employer switches to any other kind of drug test. So, it is better to refrain from illegal drugs altogether than rely upon these methods to pass your saliva drug test.
Disclaimer: We do not recommend or advocate the use of adulterants or any other tampering solutions to pass oral drug test.
How Long Does Weed Stay in Saliva?
The detection window for weed or THC in saliva is generally 24 to 28 hours after use. For chronic users, it may be detectable for slightly longer, up to 72 hours.
To increase your chances of passing a saliva drug test for weed, it is best recommended to stop smoking weed as soon as you learn about the upcoming test. Ideally, you should abstain from using THC for at least 24 to 72 hours before the test.
It is crucial to note that detection times for THC during a saliva drug test can vary between individuals, and factors such as body weight, age, sex, metabolism, and the potency of the cannabis consumed can influence how long it remains detectable in saliva.
If you are facing a saliva drug test and have recently used cannabis or marijuana, it's crucial to be aware of the detection window, marijuana laws in your state, and the specific testing requirements.
How to Pass Mouth Swab Drug Test For Amazon?
Amazon conducts a saliva drug test for their employees and include those drugs which are monitored by the Department of Transportation (DOT). As per the latest announcement, Amazon will not test for THC during pre-employment drug test.
If you are applying for Amazon and if your pre-hire drug test is coming up, make sure you abstain from any drugs for two weeks. Hydrate yourself and practice good oral hygiene.
If you are taking prescribed medications, consult with your physician if you can stop it for two weeks. If that is not recommended, let the authority knows in advance and submit all the required documentation.
However, keep in mind that there is no guaranteed way to pass a drug test, and the best way to avoid failing a drug test is to not use drugs in the first place.

Putting Water On Mouth Swab Drug Test - Does It Help Me Pass My Drug Test?
No. Putting water on the mouth swab drug test will not help you pass your drug test.

So, what is the best course of action to pass your mouth swab drug test - It's simple: abstain from drug use for an ample period before the test. You can also consider a detox regimen if you have enough time for your upcoming drug test.
If you have no idea to pass your mouth swab drug test, here are some hacks that could help you ace it.
Mouth Swab Drug Test Hacks
The best way to pass a saliva drug test is by abstaining from taking any drugs at all. In order to pass the test, it is important to consider the time left for the forthcoming test and choose effective measures to come out clean.
Check out some of the cool ways to pass your oral drug test while your drug testing is near. (Note: These might not work if your drug usage is regular. Use these methods only at your own risk)
1. Neutralized Chewing Gums
There are neutralizing chewing gums in the market such as Oral Clear, which is very effective in passing a saliva drug test. The gum capsule has some liquid inside, which should be spread after biting throughout the mouth without swallowing. After chewing it for 30 seconds, the saliva will be clear of all unwanted toxins for the next 30 minutes.
2. Saliva Detox Mouthwash
Detox mouthwash is one of the most effective detoxifying solutions to beat a mouth swab drug test. By carrying a small bottle of detox mouthwash in the pocket, one may get through an unexpected saliva test quite easily. Rinse your mouth for 2 to 3 minutes and spit out. After 15 minutes, saliva will be free from any trace of drug metabolites, alcohol, and nicotine.
There are many recommended products available in the market, but not all products are really helpful.
3. Citrus Candies
Sour candy may help you pass your oral saliva drug test. Citric candies may make your saliva more acidic and sugary, which makes it hard to detect the drugs in the saliva.
You can suck rather than chew them, which can give you enough results. This might only work for a short period, and you can use them if you are desperate enough to pass your compulsory mouth swab drug test.
4. Greasy Foods
This is the best option if you are about to take your THC mouth swab drug test. Greasy or oily foods like greasy burgers, pizza, and fries have a lot of fat in them that can entrap the THC metabolites in the fat cells, thereby helping you to pass your mouth swab drug test.
You can take these greasy foods a day before your drug test. If you cannot find any fatty junk foods, you can consume normal foods with a high-fat content in them.
Does Mouthwash For Drug Test Really Work?
Evidently, No. While some people claim that mouthwash does work for a drug test and help mask the metabolites temporarily, the effectiveness of using mouthwash to pass a drug test is a subject of debate and uncertainty.
Mouthwash is intended to maintain a good oral hygiene and hence it hardly helps you alter your drug test. Mouthwash contains ethanol which might have some impact if it comes to a saliva alcohol test.

Can mouthwash make you fail a drug test?
Possibly yes. As said above, if you are about to take your oral saliva drug test for alcohol, then there are chances that you may get positive results. If you are not taking any drugs and still get a positive result, mouthwash might be the culprit.
Some everyday substances like caffeine, mouthwash, breath fresheners, and other products which contain ethanol content in them might impact your alcohol drug test.
Remember this! Mouthwash might not impact your drug test results for other drugs like COC, MAMP, and THC.
How To Cheat A Saliva Drug Test?
You cannot cheat your mouth swab drug test as it is monitored right from sample collection. The donor’s mouth must be empty and should not contain any food 10 minutes before the drug test.
The tester will be monitoring all through the testing process, and hence one cannot tamper with the sample. The sample is initially validity tested for albumin.
Albumin is a protein that is secreted in the saliva. An adequate amount of albumin ensures the saliva sample is not adulterated, thereby making the oral drug test a reliable drug testing process.
Instead of trying to cheat your oral drug test, it is crucial to abide by the law and company policies regarding drug use and testing. If you have concerns about a drug test, be honest and upfront about any prescribed medications or substances you have used or currently using before your drug test.
Talk to the testing administrator or employer in advance and provide the necessary documentation or clarification.
Remember this! Cheating on a drug test is not only unethical but can lead to severe consequences, including loss of employment and legal issues.
Home Remedies to Pass Your Mouth Swab Drug Test
Without relying solely on some hacks, you can also try these home remedies that may help you pass your saliva drug test.
1. Hydrogen Peroxide
Hydrogen Peroxide is one of the most commonly used home remedies to beat an oral drug test. You can dilute the content with water and gargle a couple of times. The concentration of the hydrogen peroxide should be about 3% or less and mixed with one to two parts water.
Hydrogen peroxide can be used as a mouthwash after cleansing the mouth thoroughly. It is recommended to swish the hydrogen peroxide solution around inside the mouth for as long as possible, then gargle, spit out and rinse the mouth thoroughly. This process can be repeated within an hour of the swab test.
This method obviously has its own risks. Hydrogen peroxide at 3% concentration is non-toxic if consumed in small amounts, though not recommendable. Higher volumes can cause adverse side effects and tissue damage.
Keeping a bottle of hydrogen peroxide for unexpected screening test isn’t advisable. So doing extensive research before choosing this product is vital.
Some people, through online reviews claim that drinking apple cider vinegar on an empty stomach for a few days before the test helped them to successfully pass the saliva test.
There are many others who also claim taking balsamic vinegar moments before the test helped them to get through the test. Unfortunately, there is little to any scientific evidence to indicate vinegar is a fail-safe method for passing a saliva drug test.
Listerine may be a considerable option to pass your mouth swab drug test. While some claim that listerine mouthwash may help you mask your drug test results, there is no empirical evidence that it does help you ace your test.
You can also use listerine strips - Jump right into the FAQ section to know how it works to pass your drug test.

How to pass a saliva alcohol test?
The detection window for alcohol in saliva is relatively short, usually up to 12-24 hours after consumption. If you know you will be taking a saliva alcohol test, try to schedule it after 24 to 36 hours of consumption.
Some mouthwash and breath fresheners may have alcohol content, which can lead to a false positive on the test. Avoid using these products before the drug test.
How soon a drug's presence in saliva be determined?
Drugs can be found in saliva about 30 to 60 minutes after administration using oral fluid testing. Due to its brief duration, it is a great test to use in post-accident and reasonable suspicion testing scenarios.
Can cross-reacting chemicals, such as over-the-counter drugs, impact oral fluid?
The initial screening test for abused substances in oral fluids uses enzyme-immunoassay antibodies (EIA), identical to those used to test urine. As a result, substances like over-the-counter medications can result in a false-positive test result. The positive results are verified using the LC/MS/MS method.
Is Mouth Swab Drug Testing safe?
Absolutely Yes. Saliva collection is quicker, simpler, and safer for the observer and the donor than collecting blood or urine. Additionally, you can follow social distancing during the collection process.
Can I pass a mouth swab if I drank the night before?
If you are facing a standard mouth swab drug test, the alcohol consumed the night before is unlikely to affect the results of the drug test. But if you are getting tested for any other drugs, there are chances that you may get positive results.
Remember this! You should not take drugs for at least two weeks to get desirable results in your oral drug test.
How long does it take to pass a swab test?
