Best 5 Mouthwashes For Passing An Oral Drug Test In 2024 (2024)

I’ll explain how rinsing your mouth with water can help you pass a saliva drug test. This is backed by scientific research, which I will share in this article.

Using water to rinse your mouth isn’t very effective, though. Detox mouthwashes are a more convenient and reliable option for passing a mouth swab drug test. I’ll provide recipes for the best DIY mouthwashes. I’ll also list the most reliable and effective detox mouthwashes. Additionally, I’ll explain how to choose the right detox mouthwash to avoid failing the drug test.

Pressed for time? Here are the best mouthwashes to pass a drug test.

How to pass a oral(mouth swab) drug test

An oral drug test, or mouth swab drug test, is a quick, inexpensive, and non-invasive method to detect drug use. Employers often use these tests. They detect drug particles on your tongue and cheeks. The results are ready in about 10 minutes.

To pass this test, you need to wash out the drug metabolites from your tongue and inside your cheeks. You can do this with water, confirmed by research. According to a study found on PubMed (https://pubmed.ncbi.nlm.nih.gov/17137525/), chronic cannabis users were tested with mouth swab drug tests after using Kleaner mouthwash, water, and milk. Without diving deep into the study, the results showed a significant decrease in THC concentration in oral fluid.

You can rinse drug metabolites from your mouth using just water. But there’s a catch.

After using the methods in the study, the THC concentration was still high. You need to use the method multiple times to reduce the concentration below the detectable level.

Another point to consider is that this study was conducted in 2014. Since then, manufacturers of detox mouthwashes have significantly improved their products.

So, I still recommend using a detox mouthwash for passing a swab drug test. It’s more reliable and convenient.

However, you can still use water, Listerine, or peroxide if you prefer—just remember it may require multiple uses. I’ll explain how to do that later in this article.

Now, let’s talk about how to choose the best mouthwash.

What to consider when choosing a mouthwash for a swab drug test

Ingredients

This is crucial because it’s what you’re putting in your mouth. I recommend checking that the mouthwash doesn’t contain any ingredients you are allergic to. Also, ensure there’s no alcohol in the mouthwash. Using mouthwash with alcohol can cause you to test positive for alcohol.

Moreover, it could make you test positive for EtG (a marker of alcohol intake) in a urine drug test. A scientific study supports this: https://pubmed.ncbi.nlm.nih.gov/17137525/.

So, remember—no alcohol and no allergenic ingredients.

Speed of action

Think about how much time you have before the drug test. Some mouthwashes work in just 30 seconds. Others might need several applications, with each application taking about three minutes, totaling about 10 minutes.

These types are usually cheaper but require more time. If you have enough time to prepare for the drug test, you can opt for a less fast-acting product. If the test could be sudden, go for the fastest acting one.

Duration

Consider the length of time the effects last and your specific drug test situation. If you know you’ll need it to last longer, choose a mouthwash with longer-lasting effects.

Reviews

Be wary of companies that market their products as being for passing drug tests but only sell regular refreshing mouthwashes. It’s wise to look at reviews to check if people have successfully passed drug tests using the mouthwash. This way, you’ll know if it truly works.

Taste

Choose a taste that isn’t repulsive to you. Most mouthwashes require you to rinse for three minutes several times. You don’t want to feel like throwing up during the process.

Certification and approvals

Check if the product has approvals from relevant health authorities or organizations.

While detox products might not be FDA-regulated, some form of regulatory compliance can indicate that the product meets certain standards.

You don’t want to use something in your mouth that doesn’t meet product standards.

DIY mouthwashes

If you’re looking to save money or don’t have time to buy a detox mouthwash, you can make one yourself. A simple method involves swishing a solution of hydrogen peroxide or Listerine in your mouth 3-4 times. This can help remove more drug molecules.

I must warn you, these methods can burn and sting your gums. Using Listerine strips won’t work for this purpose, as they’re only meant to freshen breath. You need a liquid to effectively wash out the drug metabolites from your mouth.

After using peroxide, it’s a good idea to chew some mint gum. This will help change the taste in your mouth.

How to pass a saliva drug test with hydrogen peroxide

Start with a 3% hydrogen peroxide solution, which is commonly available at drugstores. This concentration is safe for oral use and is typically used for minor wound cleaning and oral hygiene.

Pour a small amount (about one tablespoon) of hydrogen peroxide into a cup. You’ll use this for rinsing your mouth.

About 30 minutes before your test, begin the rinsing process.

• Take a mouthful of hydrogen peroxide and swish vigorously in your mouth for 30 seconds. Make sure to reach all areas of your mouth, including under the tongue and along the gum line.
• After swishing, spit the hydrogen peroxide out.
• Do not swallow it as it can cause stomach irritation and other digestive issues.

You can repeat the swishing process a couple of times. Each rinse will help reduce the amount of drug residues in your mouth.

After your final hydrogen peroxide rinse, rinse your mouth thoroughly with water a few times to remove any remaining hydrogen peroxide taste and to soothe your mouth.

Timing is crucial. The effects of hydrogen peroxide in cleansing your mouth are temporary. The best window of opportunity for taking the test is within 30 minutes after your last rinse.

In preparation for your test, maintain good oral hygiene in the days leading up to it. Brush regularly and use dental floss. This reduces the chances of drug residues sticking around in your mouth.

After rinsing and before the test, avoid eating, drinking, smoking, or chewing gum.

Tips for success

• While hydrogen peroxide is a popular home remedy, its effectiveness can vary based on the type of drug test and the substances you’ve used. It’s more of a temporary solution.
• Be aware that some testing techniques might be able to detect the use of oxidizing agents like hydrogen peroxide. Always consider the risk of relying solely on this method.
• For more reliable results, consider using methods approved by healthcare professionals or following guidelines set by the testing organization.

How to pass a saliva drug test with Listerine

Opt for a standard Listerine mouthwash, preferably one without artificial coloring. The antibacterial properties help clean the mouth, but the coloring can leave residues that might raise questions during the test.

Use the Listerine approximately 30 minutes before your test. This timing is crucial as the effects of the mouthwash are temporary and most effective within a short window.

• Take a generous amount of Listerine (about one-fourth to one-half of the bottle) and swish it around your mouth vigorously. Make sure to cover all areas: under the tongue, inside the cheeks, the roof of your mouth, and along the gum line.
• Continue to swish the mouthwash in your mouth for at least 30 seconds to a minute. The longer you can manage without discomfort, the better, as it allows the mouthwash more time to act on any residues.
• After swishing, spit out the mouthwash. Do not swallow it, as it contains ingredients that are not meant to be ingested in large amounts.

If you feel it’s necessary, and you have enough mouthwash left, repeat the process for added assurance. However, one thorough swish is typically sufficient.

After your final use of Listerine, rinse your mouth with water a few times to remove any lingering taste and to reduce any potential irritation from the alcohol in the mouthwash.

After rinsing with Listerine and water, avoid eating, drinking, smoking, or chewing gum until after your test. Introducing new substances into your mouth could reintroduce contaminants.

Tips for success

• Listerine can mask or temporarily remove traces of substances in the saliva, but it’s not a guaranteed way to pass a drug test, especially if the test is designed to detect masking agents.
• Maintain good oral hygiene in the days leading up to the test, including regular brushing and flossing.
• Consider the type of test and the substances you are trying to mask, as results can vary based on these factors.

Conclusion

You can pass a saliva drug test using just water or solutions like peroxide or Listerine. However, I recommend using a commercial mouthwash instead. It’s more convenient to handle and use. You can easily carry it in your pocket and use it quickly if needed.

The fastest acting option is Oral Clear Gum, but it is pricey. I suggest using it only in the most important situations.
