Here’s How Long CBD Can Stay In Your Body

Posted on

So, a major concern people have when they consume CBD oil is how long it will stay in your system. This could be for a number of reasons.

Perhaps you’re facing a drug screening at work and you’re not sure if they are testing for CBD as well as THC. While this rarely happens, it has been known... and sometimes it just isn’t worth taking the risk.

Whatever the reason, this article will cover all you need to know about how long CBD stays in your system. But first, let’s go over some of the basics in order to make sure we’re all up to speed.

How does CBD make you feel?

CBD feels warm and relaxing

First up, when you purchase a CBD product for the first time, you may well want to know how it’s going to make you feel. You might have heard from friends or the media just how powerful it can be, and are therefore concerned about how it could affect you.

Well, let us put any fears you have to rest. Although CBD does indeed come from the controversial cannabis plant, it is 100% non-intoxicating. That psychotropic effect comes from THC, which is why most drug tests are only looking for THC and not CBD.

So how does CBD feel, then? To be honest, the chances are you won’t feel much at all.

Having said that, some people do say that they feel a warmness descend through their bodies. Or maybe something more like a sense of relief coming over them. Many people report that their mind-chatter slows down and they feel peaceful yet alert.

Of course, there are many factors that may play a role in how CBD feels. Not least the size of the dose and the method of consumption. For a more in-depth look at how it feels to take CBD, you can read this article we previously published that goes into much more detail.

How long does CBD take to work?

Another common question for newcomers to CBD is how long it takes to work. This is an important question as it allows you to devise an appropriate dosing schedule, as well as choose the product and means of delivery that is best suited to you.

To answer this question, there are a few things to take into consideration. First of these is what method you are using to take your CBD. Let’s cover the main ones and discuss how long you can expect for each to take effect.

  • Sublingually

The most effective way to take CBD oil is via the sublingual tissue underneath the tongue. To do this, you simply put a few drops of oil under your tongue and hold it there for a minute or so.

The CBD will be efficiently absorbed through the tissue and directly into your bloodstream. From there, it will be pumped throughout your body and begin to take effect. Therefore, you can expect the effects of the CBD to start working in pretty short space of time - about 5-20 minutes, by most accounts.

  • Vaporizing or smoking
When you vaporize or smoke CBD, the CBD is absorbed via the lungs. This is also quite efficient as the CBD gets straight into your bloodstream. When smoked or vaped, CBD will take effect very quickly - within a couple of minutes, in fact.
  •  Topically

Applying a CBD balm or salve is a smart way to fight localized aches and pains. But it’s not the most fast-acting method of taking CBD. You see, when you apply CBD to your skin, it gets absorbed through your pores. This means that the effects won’t take root until an hour or more after application

  • Eaten

CBD edibles are very popular products. They can come in the form of gummy bears, chocolate, or healthy smoothies and shakes. But when it comes to effects, edibles aren’t the quickest to start working. Because the CBD has to go through your digestive system and be absorbed through the lining of the gut, the effects can be delayed for as 20 minutes to an hour. If you eat CBD edibles on an empty stomach, they could work much quicker, however.

Side note: Along with the method of consumption, there are loads more variable that will affect how long it takes CBD to work. These include your height, weight and age. Your levels of health, diet and activity levels will also play a role. For a more detailed explanation, check out this recently published article.

How long do the effects of CBD last?

CBD and THC come from the cannabis plant

Now we know how CBD makes you feel and how long the effects take to kick in, let’s look at how long you can expect those effects to last. Again, this largely depends on a number of different factors. The size of the dose and method of consumption are probably the most important.

As you can imagine, the bigger the dose of CBD you take, the longer you can expect the effect to last. However, as everybody is unique and can react to CBD in different ways, there is no accurate way of working out how long the effects will last.

The only thing you can do is try a certain dose of CBD yourself and then make an effort to be conscious of when the effects wear off. 2-5mg of CBD is a good place to start, increasing the dose as you see fit depending.

Although there will be some variation, you can generally assume that a small to moderate-size dose (5-10mg) will last between 1-3 hours. A larger dose, say 10-20mg, may last 3-5 hours.

We much reiterate, however, experimentation and self-assessment are the keys to discovering how long the effects of CBD last for you. This will help you to devise a suitable dosing schedule that achieves the results you want. This article can also help you decide how much CBD you should take.

How long will CBD stay in your system?

With CBD exploding onto the scene so dramatically in recent years, it’s understandable that many people want to know how long it stays in your system. However, it’s a difficult question to answer. As we keep saying, everyone’s bodies are different and there is no one-size-fits-all answer. Additionally, there just hasn’t been that much research done on the subject.    

Despite these limitations, we can make an educated guess based on the evidence that is available. Like this study from 1991, which looked at 14 subjects with Huntington's disease who took high doses of CBD for six weeks.

After consuming about 700mg per day during this time period, the study found that just one week after they stopped dosing, CBD levels in subjects blood averaged just 1.5 ng/ml. After one week, CBD was “virtually undetectable”.

The study also stated that the estimated half-life of CBD was 3-5 days and that there were no significant differences between genders. From this, we can ascertain that, for most people, CBD will completely leave their blood after just one week.

Unfortunately, there are no studies on how long CBD remains detectable in your urine, saliva or hair. However, your saliva usually only offers evidence of pharmaceutical use for a couple of hours to one day. Also, we can assume based on studies of THC detection times that even a moderate to large daily dose of CBD - say 10-100mg - should be cleared from your urine within a couple of weeks at the most.

When it comes to hair, however, it’s a different story. This is because your hair can keep a pharmacological record of what you have consumed during your entire life. Even if you cut the hair on your head, your body hair will still preserve this information. However, most hair tests will only look at the last inch-and-a-half of your hair, which represent about the last 90 days of your life.

WIll CBD show up on a drug test?

Blood test for CBD

This is another cause for concern for many of you trying CBD for the first time. However, you need not fear. As we mentioned earlier in this article, drug tests are almost always looking for signs of THC - the psychotropic ingredient in cannabis - and not CBD.

But don’t some CBD oils also contain small amounts of THC? Yes, they do. Although the THC concentrations in any reputable CBD oil are nowhere near high enough to cause you to test positive in a drug screening.

This is why it is so important that choose a product from a reliable and trusted company, like ourselves… Just scroll down our front page and take a look at all the five-star reviews from many happy customers.

How long does THC stay in your system?

Unfortunately, most forms of cannabis are still illegal in many parts of the world. This is despite modern medical science revealing the countless health benefits that it offers. That’s right, it’s not just CBD that offers so much therapeutic value.

However, because of outdated laws and close-minded politicians, many are still persecuted for using THC. That’s why many people have to be very careful not to get caught with weed on them - or in them! If that includes you, knowing how long THC stays in your system can be vitally important.

Again, however, the answer is not at all straightforward and clearcut. Not only does THC get processed through the body at different speeds depending on numerous factors, there are also many ways of testing for it. While the most common test analyzes urine samples, blood, saliva, and hair can also be tested for signs of THC use.

Here’s a brief overview of how long THC remains detectable with regards to each of the most common drug tests. These answers depend on how much and how often you consume THC.

  • BloodBetween 3 and 30 days
  • Urine - Between 2 and 100 days
  • Saliva - Between 12 and 24 hours
  • Hair - Theoretically, as long as you have been alive. However, most hair tests will only look at the last 90 days.

How do they test for cannabis?

THC can stay in your system for up to 100 days

As we mentioned above, most drug screenings for cannabis are actually looking for THC or metabolites of THC, not CBD or any other cannabinoids. This is because THC is the cannabinoid that’s responsible for the intoxication effects of cannabis.

There are many types of tests that are used to test THS, the most common being urine, blood, saliva, and hair tests. Others include breath, sweat and even fingernails tests, although it’s pretty unlikely you’ll come across these.

Most tests will consist of you giving a sample - whether it be urine, blood, saliva or hair - which is then analyzed using an immunoassay that can detect THC or its main metabolite, THC-COOH. If the test signals the presence of either of these, you will undergo a more accurate and reliable test to confirm the original results.  


Many CBD users, as well as first-timers, want to know how long CBD stays in your system. Although most drug tests are only looking for THC, some do look for CBD. And as the consequences of failing a drug test can be severe, it’s often not worth taking the risk.

However, you’ll be pleased to know that CBD seems to be undetectable in your blood after about a week. From this, we can make an educated guess that it will also not be present for much longer than a couple of weeks at most in your urine, while your saliva will probably be free of CBD after a few hours.

If you want to make doubly sure that you are in no way in risking a positive test result for cannabis user, be sure to only buy CBD from a trusted and reliable seller.
