How Long Does THC Show Up In Saliva?

Many people in the United States use marijuana for many reasons. When someone uses marijuana, THC will be present in their system. The majority of drug tests are designed to detect THC in a person’s system.

Typically, urine drug tests and blood drug tests will detect THC for longer periods. What about saliva drug tests? How long will the THC show up in your saliva?

It depends on how long the substance can be detected in your mouth. It depends on how much marijuana you’ve smoked and how often you smoke.

If you’ve only taken a puff of marijuana, it should leave your saliva in 12 hours or so. Some studies have shown that THC will no longer be detectable after 12 hours of the user’s last hit.

However, certain tests can detect THC in the user’s saliva for 48 hours. Regardless, you can expect the actual duration to depend on several factors, including how much marijuana you smoked, how frequently you smoked, your health, and your age.

The only surefire way to ensure that your saliva will not contain THC is by not using marijuana. You can try beating a saliva drug test using Listerine, but there is no guarantee that this method will work for you.

Can Listerine Help Cheat A Saliva Drug Test?

You’ll find that some people claim they’ve beaten saliva drug tests by using Listerine. Why would Listerine help? Ultimately, there is no exact reason.

There haven’t been enough scientific tests to explain why Listerine would help someone cheat a saliva drug test. However, there are some ideas floating around.

Some claim Listerine is going to eliminate THC molecules while removing bacteria from the user’s mouth. Others suspect the Listerine is going to destroy the THC until it is no longer detectable in the saliva.

If you’re going to use this method, it is essential to be precise. You’ll also want to fully understand the consequences because it may not work for you.

What About Water?

While some people have used Listerine to cheat saliva drug tests, others claim water is equally effective. In fact, some studies show that water might be better for this purpose.

In 2014, a study was conducted to determine how effective mouthwashes and water would be for removing THC concentrations. 11 regular cannabis users were studied for four days.

During the first three days, these individuals smoked marijuana as they normally did. Their saliva was tested at different points including 15 minutes, an hour, 3 hours, and 24 hours after they’ve finished smoking.

The participants used whole milk, water, and mouthwash to try to reduce the THC concentrations found in their saliva.

Surprisingly, it was found that water was more effective than whole milk and mouthwash. Therefore, it might be a good idea to use a combination of water and mouthwash to beat an upcoming saliva drug test.
