The marijuana or hemp plant is of great medical significance, but many people do not know. Instead, they capitalize on the negative aspect of the plant. This plant is also called the Cannabis sativa, and it is the source of the cannabidiol, a chemical substance. In marijuana, delta-9-tetrahydrocannabinol (THC) is the main content, but the least in the cannabidiol (CBD). More than 113 different chemicals can be derived from this plant. These chemicals are collectively called cannabinoids.

How long does CBD oil stay in your system? To answer this question is it also necessary to know that cannabidiol mainly affects the brain. Thanks to this, it can treat a wide range of health conditions including such diseases as schizophrenia and Parkinson`s disease. Unlike THC, cannabidiol does not have a psychoactive effect, so it is a legal treatment.

After what time does the body get CBD out?

So, how long does CBD oil stay in your system? This depends on several factors which are:

  • Metabolism. This factor is important when it comes to the speed of metabolizing and excreting CBD from the body. Metabolism also tends to differ from an individual to an individual;
  • Dosage. How long the compound will remain in the body depends on how much cannabidiol a person consumes;
  • Intake frequency. This factor determines after what time the derivative will be excreted as well;
  • Way of administration. This aspect affects both the effects and presence of cannabidiol in the human body. For example, if consumers smoke CBD, it will get into the blood almost immediately. At the same time, if they eat it, the effect will appear after at least an hour.

Let`s see what the studies say about it. Therapeutic Drug Monitoring published a study in 2005. There were volunteers who received capsules with 1.35 mg of cannabidiol. It was found that the derivative was not detected in their blood after six hours.

Another study was carried out in 1991 and published in Pharmacology Biochemistry and Behaviour. It was on how much cannabidiol the blood would contain in case of high dosage taken daily. For one and a half months the patients with Huntington`s disease were taking 700 mg of the compound every day. When they stopped consuming it, the researchers took their blood after one week. The result was 1.5 nanograms per milliliter.

According to this study, the researchers also discovered that the approximate time CBD remains in the blood is three to five days. There is no big difference between men and women as well. Thus, we can state that cannabidiol is highly likely to leave the human body in a week or two due to the mentioned before factors.

How long will CBD effects last?

The way you consume cannabidiol determines how long the effects are going to last.


This way is one of the most common consumption methods because it is easy. According to the studies, though, this way is not an efficient one. This is because the compound is metabolized by the liver, so the concentration of CBD is reduced before it gets into the blood. In fact, only 5 per cent of the derivative is received by the blood. The effects appear in one or two hours.


They regard this method is a more effective one in comparison with the mentioned above. In this case, CBD is put under the tongue, so the body receives the compound without making use of the digestive system and liver. That is why cannabidiol gets into the bloodstream rather quickly and the molecules are not broken down.


This method is also effective enough because cannabidiol is transferred directly into the bloodstream through the lungs. A study conducted in 2007 showed that the compound was detected in 72 hours after smoking. The effects appear in three minutes, so this way of consuming cannabidiol is widely used by people who want immediate relief.


There are different kinds of topicals such as creams, lotions, salves and many other products. Consumers are allowed to put them directly onto the skin. The compound is absorbed by the skin cells and is transferred into the bloodstream. The effect appears after 1.5 hours.

Potential Risks Of Taking CBD

According to the 2017 reports of the World Health Organization, the CBD, without its adulteration with any other thing that is in its purest form, has no any side effect. It is widely tolerated and safe by both animals and humans, and there is no evidence that it will cause any abuse or dependence. The national institutes of health have also said that the CBD has been taken through the mouth for up to four weeks daily at a dose of 1,500 mg without any issues. However, because all drugs have a spectrum of actions, there are few risks associated which will be listed below:

The side effects like a dry mouth that are similar to atropine have been reported. Decrease blood pressure, drowsiness, and liver injury has also been reported, but the latter effect has no reliable scientific backup.

Another not so good thing about the compound is that it has drug interactions. So anyone intending to take it along with any other drug should be sure their doctor is aware of it. The agent also has no standard regulations making it difficult for people to know how to go about its legality.

Can CBD Oil Be Detected During a Drug Test?

THC is the psychoactive substance that causes legal problems, but to find out how long THC oil stays in your system you need to read a different article.

CBD oil is very improbable to generate a positive test for THC, but it’s still possible. If we look at figures, cannabidiol products that are derived from hemp can contain up to 0.25% THC. A false-positive result can exist during a drug test. It all depends on how strict the employer is.

If you seek to be extremely cautious and use the compound with absolutely no THC, search for broad-spectrum products that have pure CBD isolate.


How long does CBD oil last in your system? This is a persistent question that many readers ask. The topic of cannabidiol is very vast, but the most important things that are expected to be at the fingertip of anyone that is planning to involve in the substance are discussed already. One must be sure of their choice of CBD and make sure their trusted medical doctor is involved in all the processes. Many types of research have been carried out, and more are still on. We hope we answered all your questions!
