How Long Does CBD Stay in Your System?

If you are looking at an employment opportunity that requires a drug screen, there's a chance that they might test for THC and CBD. It does not happen often, but it has been known to occur. You can’t hope that you won’t be tested for CBD. That is why it’s important to know how long CBD stays in your system.

Whether you’re looking for basic knowledge or facing a drug screen and you’re concerned a recent vaping session might show up, we will offer you all the essential information you need to know about how CBD works and how long it stays in the body.

How Should You Feel After Taking CBD?

While CBD comes from the controversial cannabis plant, it is commonly confused with THC especially when it comes to the mode of operation. Different words are used to define the experience that one receives after taking CBD.

However, CBD is non-intoxicating, non psychoactive and DOES NOT GET YOU HIGH. The experience and affects commonly defined are usually caused by THC which has psychotropic elements. In most cases, when you're going through a drug test, they are generally looking for THC. Usually, CBD is never in the picture.

Does that mean you won’t feel anything when you take CBD? Well, the experience differs from person to person. But, don’t get your hopes too high (literally). There’s a fair chance you might not feel much. Despite its qualities as an anti-inflammatory, anti-depressant, and a pain reliever, their experience effects are barely noticeable.

Some users have reported a warm fuzzy feeling within their bodies, while others express a sense of relief, while others experience a sense of calmness and peace with increased alertness. Your experience might be the same or slightly different.

Some factors that could affect how you feel after taking CBD include:

  • The amount of CBD you take
  • The method of consumption
  • How frequently you take CBD

How long until CBD starts to work?

If you’re new to using CBD, it’s important to know how long it takes for it to start working. The answer to the question is not straightforward. It depends on many factors; the main one is how the compound is taken.


This is the most effective way to take CBD. It is placed under the tongue in the sublingual tissue. Only a few drops of CBD oil are placed under the tongue and held there for about a minute. The product is effectively absorbed straight into the bloodstream where it is taken around the body. In most cases, you can expect to feel some effect in about 5–20 minutes.

Vaping or smoking

You can also take CBD by vaping or smoking (smoking the actual CBD flower or bud), in which case the CBD is absorbed through the lungs. This method is also effective because the CBD is not digested. It is absorbed into the bloodstream through the lungs. Within a few minutes, you should start feeling the effects of the compound.


This is one of the most preferred methods of taking CBD. You can consume it in the form of gel-like capsules, gummy bears, vapes, smoothies, or chocolate. It takes time before it can start working because it has to be digested first. You might have to wait up to 20 minutes if you're on an empty stomach and up to an hour if taken after food.

The method of consumption is not the only factor that determines how quickly the CBD kicks in. Other variables like your weight, age, and height must be considered as well.

How Long Do The Effects Last After They Kick In?

Again, there is no straightforward answer to this question. Once the effects kick in, there are a few factors that determine how long they last. It is affected by the amount of CBD taken, and the method of consumption.

The larger the dose, the longer the effects usually stick around. However, there is no accurate method of working out how long the effects will last. If you’re more interested in the time, you can try to take a specific dose and try to time how long it takes for the effects to wear off.

With the misconception that goes around CBD, it is understandable why most people would want to know how long it stays in the system just in case they have a test coming up. Unfortunately, it is not an easy question to answer.

Different individuals process CBD differently which makes it difficult to have a “one-size fits all” answer. It doesn’t help that the use of CBD has exploded in the recent past and not much research has been done on the subject.

But, it’s not all gloomy. There is one research conducted in 1991 that can help shed light on the subject. During this research, subjects consumed up to 700mg of CBD per day for six weeks. A week after the study, the subjects were tested. It was found that CBD levels in their blood were 1.5ng/ml.

The same study estimated that the half-life of CBD was estimated to be 3-5 days without much difference between the genders. From the findings of this study, it can be deduced that CBD can be virtually undetectable after a week in the blood.

While this might be good news for some, it should be taken with a pinch of salt. That's because there are no studies that show how long it takes for the CBD to be undetectable in urine, hair, or saliva. Based on the detection of THC studies, it can be estimated that it takes a couple of weeks at most for large daily doses of CBD of about 10-100mg to clear from the body.
