CBD Saliva tests

Complete Guide to CBD Saliva Testing

In the United States, saliva tests are the most commonly used drug tests to detect CBD traces. Saliva tests are: quick, easy, and accurate.

They are also the least invasive of the three types of drug tests. A saliva test is generally considered more accurate than a urine test because CBD is not water-soluble, so it does not appear in urine tests. 

It is crucial to note that CBD can be retained in the body for up to 72 hours. A saliva test might not be able to detect CBD if it was consumed more than three days ago.

What Is a Saliva Test?

There are two main types of saliva tests - cannabinoid identification assay (CAA) and cannabinoid extraction method (CEM). 

CAA uses an enzyme called ligase to break down cannabinoids into their components, while the CEM extracts cannabinoids from the sample using a solvent.

The results of these tests vary depending on the specific test used. However, they typically indicate whether or not any CBD is present in the saliva sample. The information may be enough for doctors to recommend additional treatments or therapies based on the results.

How Long Does CBD Stay in the Saliva?

The short answer is that it depends on how much/frequently you use it and your body chemistry. CBD can stay in your saliva for up to 72 hours. Regular use of CBD can build up in your system and remain detectable for up to a week.

Individual body chemistry will also influence how long CBD traces stay in your saliva. Some people metabolize CBD more quickly than others, so it may not be detectable in their system for as long.

If you're concerned about drug testing, it's always best to err on the side of caution and avoid using CBD products altogether.

How to Interpret the Results of a Saliva Test About CBD

How to Interpret the Results of a Saliva Test About CBD

When it comes to CBD oil, one of the most popular ways to consume it is through a method known as "saliva testing." It involves using a small dropper to place a drop of oil under your tongue, holding it there for a minute or so, and then spitting it out. 

The saliva test is a great way to determine how much CBD is in your system. It can also help you gauge how well your body can process and use the compound.

Interpreting the results of a saliva test can be a bit tricky. Here's a quick guide to help you understand what your results mean:

Take Note of the Color

The first thing you need to look at is the color of your saliva. If it's clear, the CBD is fully dissolved and ready to be absorbed into your system. If it's cloudy, the CBD is still partially dissolved and needs to be further processed by your body.

Check the Amount of Oil Left

You'll want to pay attention to the amount of oil left in your mouth after you spit out the saliva. If there's a lot of oil left, your body has a hard time processing CBD. On the other hand, if only a little bit of oil is left, your body can effectively use CBD.

Pay Attention to Consistency

You'll want to take a look at the consistency of your saliva. If it's thin and watery, that means that the CBD isn't properly absorbed by your body. Thickness and stickiness indicate that the CBD is being effectively absorbed.

Note that these are just general guidelines - your results may vary depending on a variety of factors:

  • Your metabolism;
  • The quality of the CBD oil you're using;
  • The amount of CBD you're taking. 

If you're unsure how to interpret your results, don't hesitate to contact a CBD expert for help. They can help you with more specific advice based on your situation.

Considerations for Taking a Saliva Test

The first thing to know is that there is no “normal" level of CBD in the blood. Levels will vary depending on how much CBD you've taken when you took it and other personal factors.

That being said, a typical range for CBD levels in the blood is 0.05-0.15 mg/mL. If your test results fall below this range, CBD isn't having any effect. On the other hand, results above this range show that you may take too much CBD, and it's about time to adjust your dosage.

Keep in mind that CBD levels can vary daily, so if your results are on the borderline, it's worth retesting to see if there's a trend. On the other hand, if you're taking CBD oil and not seeing any results, it's worth trying a different brand or product.

Not all CBD oils are created equal; some may be more effective than others.

If you're still not seeing any results after trying a few different products, it's possible that CBD isn't the right solution for you. However, many other natural remedies for anxiety and insomnia exist, so don't give up hope.

Benefits of Taking a Saliva Test

Benefits of Taking a CBD Saliva Test

A saliva test is one of the most accurate methods to find out the CBD levels in your body. Here's a look at the benefits of taking a saliva test to know your CBD levels.

Quick and Easy

A saliva test only takes a few minutes to complete, and it’s easy to do. All you need is a cotton swab and some saliva.


A saliva test is one of the most accurate methods for determining CBD levels since it is directly metabolized in the saliva.


There's no need to draw blood or urine, which can be uncomfortable or even painful for some people. Also, it doesn't require any blood tests or other invasive procedures.


Unlike blood or urine tests, saliva tests can be done at home with no special equipment. All you need is a clean piece of cotton or paper to collect your saliva.


A saliva test is a convenient way to test for CBD levels. You can do it at home and don't need to make an appointment with a doctor.

The Risks of Taking a Saliva Test

Recent research has shown that saliva tests can be unreliable when measuring CBD levels. A study published in the Drug Testing and Analysis found that saliva tests can overestimate CBD levels by up to 50%.

CBD is absorbed into the bloodstream more slowly when taken orally, so that it can take up to two hours for the levels to peak in the saliva.

In addition, the study found that saliva tests can underestimate CBD levels. So, if you're taking a saliva test to measure your CBD levels, you might want to consider another method.


CBD is detectable in saliva. However, the amount of time that it will remain detectable in your system will depend on how much CBD you have used and how often you have used it. 

If you are a heavy user of CBD, it may remain detectable in your saliva for up to 72 hours after your last use. Light users are likelier that it will only be noticeable for a few hours after the last use.
