The legalization of CBD and CBD products has triggered a general increase in the level of research aimed at discovering its therapeutic potentials, mode of action, possible side effects and rate of metabolism. Even with these levels of study, there are still drug tests which have been designed to arrest psychoactive cannabinoids such as THC. These tests are primarily designed to discourage the indiscriminate use of cannabis by people. Refer to our article on CBD drug test for more information. Due to these levels of research and drug tests, there has been an increased interest in understanding how long CBD stays in the body before being passed out.

While this may sound like a very simple question, it is quite impossible to pinpoint just how long CBD will remain active in the body before being cleared. The activity of CBD is affected by the availability of receptors, body chemistry, level of the disease, and concentration of CBD in circulation.

CBD just came to limelight recently, and there are still some unanswered questions about its activity, dosage and clearance time. However, data gathered from research has proven that CBD takes an average of 5 to 30 minutes to set out and its activity can last for up to four hours. This information is however subject to further research and evidence.

Some reports have shown that even after attaining the maximum clearance time of four hours, it will linger in your body system for a while.

Some researchers who studied the half-life of CBD made a submission that CBD can linger in your system for up to four days even after the effects has worn off. One of such studies estimated the half of CBD to be 2 to 5 days. That’s a lot of time.

Some other research revealed that the mode of administration of CBD could play a key role in determining its clearance time.CBD administered orally tends to have shorter clearance time than other methods of administration due to increased absorption and bioavailability.

It is pertinent to note that, the traces of CBD lingering after the estimated clearance time may not be visible for some time after you’ve consumed it even though it is still very much active in your body system. The amount of CBD lingering in your system after the clearance time depends on how much of the compounds you ingested, your age, weight, and level of the disease condition. These are also factors that determine CBD activity in our body system.


As a general rule of thumb, it is generally believed that it takes CBD about one week to leave the system and if there is any trace of THC in your CBD product, you may likely test positive during the drug test.
