Like hair, saliva testing for CBD or THC is incredibly rare for occupational or legal reasons. However, the drug's components may be detected within minutes of taking the drug and may last up to 36 hours, depending on dosage and frequency of use. Although CBD does not produce the same intoxicating effects as THC, it is stored in the body. However, research has consistently shown different results.
The general rule of thumb for intermittent users is that cannabis can be detected in saliva 24-72 hours after use. For chronic users or medical patients, one study has shown a detection of up to 8 days. Depending on the amount of CBD you take and the frequency, a saliva test could still detect use 24-36 hours after the last intake. The saliva test is another test that focuses on short-term use.
If you have taken CBD or THC in the last 3 days, there is a chance that you will test positive. Prolonged use and ingestion of large amounts can increase this window. THC can be found in saliva for about 72 hours, but chronic use of THC-contaminated CBD products may widen this window of detection. Saliva tests begin to detect CBD use within minutes of consuming the substance, but this type of test is not commonly used for occupational or legal reasons.
In some cases of heavy use, CBD can remain in the system for up to a week, with detection windows extending to over a month. If you use cannabidiol-based products that also contain THC, you probably want to know the answer to the question of how long CBD stays in your system. Before answering the question "how long does CBD stay in your system", let's see how long the effect of the substance lasts. Up to 70 percent of CBD products contain an unmarked percentage of CBD, do not have the same CBD content as the packaging claims, or contain THC and other unlisted cannabinoids.
It is a common misconception that CBD and THC are the same; although CBD is a natural supplement, it is still possible for THC metabolites to be detected during drug testing. If you smoke CBD from dried flowers or use a cartridge for vaping, CBD enters the bloodstream in a matter of seconds. It should also be noted that since CBD products are not regulated by the FDA, you may be taking CBD mixed with other cannabinoids, which could increase detectability. The duration of CBD's effects depends largely on the method of consumption, but in general, CBD lasts between 2 and 6 hours.
