What Is CBD and Saliva Test?


CBD, or cannabidiol, is a compound found in the cannabis sativa plants. The CBD products available in the market are mostly extracted from the industrial hemp plant, a sub-species of the cannabis plant.


It is important to note that CBD and THC, both cannabinoids, can be found in the hemp plant. However, they differ from each other. THC is a psychoactive compound that is found in high concentrations in recreational marijuana products. It is a major compound that induces “high”, “euphoria” and “munchies”.


Now, what is a saliva test? Saliva tests are employed by law enforcement to detect drug use, including substances like cannabis, amphetamines, cocaine, and opioids.


During a saliva test, a sample is taken from the individual’s mouth, and immediate results indicate recent drug use. In the context of CBD and saliva tests, you should know that CBD itself is not typically the primary target in these tests.


However, consuming CBD products still may lead to a positive result, especially if the product contains a trace amount of THC.


How Does Your Body Process CBD?


Another important thing to know about CBD is how your body processes it. The way your body processes CBD depends on the administration method. When taken orally through dietary supplements, edibles, or oils, it is absorbed through the digestive system, typically starting its effects within an hour.


Vaping or smoking CBD, on the other hand, allows it to enter the bloodstream almost immediately and produces faster effects on the body and brain. The effects of CBD typically last 1 hour to 6 hours depending on factors like potency, dosage, method of consumption, and individual metabolism.


Factors That Affect How Long CBD Stays in Your System


You should be aware of a few factors that can impact how long CBD remains in your system (e.g., saliva, blood, hair) before we address the question: “How long does CBD stay in saliva?”


•  Consumption Method: The way you take CBD, whether orally (edibles, oils) or through inhalation (vaping, smoking), influences how quickly it enters your bloodstream and affects the duration of its presence in your system including saliva, blood, hair, etc.

•  Dosage: Higher Dosage of CBD may take longer to metabolize and eliminate from the body.

•  Frequency of Use: Regular and frequent CBD consumption can result in a longer detection window in your system. 

•  Individual Metabolism: Metabolic rates vary among individuals which can affect how quickly the body processes and eliminates substances including CBD.

•  Body Fat: CBD is fat-soluble, and higher body fat percentages may result in longer retention time in the body.

•  Hydration Levels: Staying hydrated can support the body’s natural process of elimination.

•  Liver Function: Metabolism of CBD occurs in the liver. So, any issues with liver function may affect processing time. 


How Long Does CBD Stay in Saliva?


CBD use can be detected in saliva testing minutes after use. The length of time CBD remains in your saliva is determined by the things we've just discussed.


For occasional and moderate consumption, traces of THC in CBD may be detectable for 24 to 36 hours after the last intake.


In cases of high and daily consumption, saliva tests could potentially detect CBD for up to 7 days post-consumption.


It’s worth noting that individual variations, the specific CBD product, and the sensitivity of the test can influence the detection period.


If you use full-spectrum CBD frequently or in a significant amount that contains THC, the saliva tests may continue to detect it for a longer duration.


Can You Test Positive in a Saliva Test for Taking CBD?


To put it plainly, yes, you can test positive in a saliva test for taking CBD. 


However, you should know that CBD drug tests screen for THC, not CBD. THC, the psychoactive component of cannabis can be found in CBD-infused edibles and topicals in trace amounts (0.3 percent). 


Though this small amount of THC is legally allowed, in theory, the saliva test may show positive results if you consume it frequently. That is why, as a conscious CBD user, you should know the difference between  CBD Vs THC.


Besides, CBD products are not regulated by the FDA (U.S. Food and Drug Administration). So, there are a plethora of CBD products found in the market that don’t follow the legal guidelines  (CBD Laws by State). These products have more THC than the labels claim. 


To avoid positive saliva test results, it is also important to purchase CBD products from a reputable  online CBD shop that provides a third-party lab test result or certificate of analysis (COA). This document discloses the results of the manufacturer’s testing for CBD, THC, and other contaminants.


How Long to Wait Not to Test Positive in a Saliva Test?


You may avoid a saliva drug test positive result by keeping in mind how long you should wait before going through saliva tests.


1.  Occasional Use: THC traces in CBD can be detected in saliva for 6 to 8 hours. So, make sure to wait at least this long before going through any drug test process.

2.  Moderate and Regular Use: For moderate but regular consumption (several times a week), traces may be detectable for 24 hours.

3.  High and Daily Use: With high and daily CBD consumption, traces can potentially be detectable for up to 7 days after the last intake.

4.  Consumption Method Matters: The form in which CBD is taken (edibles, oils, vaping, etc.) can influence how long it stays in the system.

5.  Individual Variations: Factors such as metabolism, body fat, and hydration levels contribute to variations in detection times.

How Do You Detox from CBD Faster?


Detoxing from CBD Faster involves supporting your body’s natural processes of metabolizing and eliminating the compound. While there’s no guaranteed way to expedite the process, you can consider the following:

4.  Sauna or Sweating: Sweating can help in the elimination of substances, so activities like saunas or exercise may be helpful.
