How Long Does CBD Stay in Your System
CBD is becoming increasingly popular. And with more and more people using CBD supplements, many have questions about how long CBD products remain in the body after consumption. Below we’ll explain how the body processes CBD, what the substance’s half-life is, and much more.
How CBD works
CBD works primarily by interacting with the endocannabinoid system, a regulatory network that keeps the body functioning at its best. Unlike other cannabinoids, CBD doesn’t bind directly with the ECS’s receptors, but works behind the scenes to deliver its unique effects.
The situation becomes a little more complicated because you can take CBD in a variety of different ways, with the method of administration playing a pivotal role in how the compound is metabolised (broken down and distributed around the body).
If you take CBD orally, for example, it has to pass through the digestive system before it can take effect. But, when taken sublingually (under the tongue) or inhaled through a vaporizer, CBD can bypass the digestive system and get to work faster.
How is CBD processed?
Once consumed and absorbed, CBD travels to the liver where it’s metabolised into a variety of compounds that your cells can use. This metabolism is carried out by the same group of enzymes responsible for breaking down roughly 60% of all medications available on the market.
From the liver, CBD metabolites move around the body, where they may interact with a wide variety of receptors.
Although that outlines the basic journey of CBD, what we’re interested in is how long the interaction between CBD metabolites and receptors last—how long CBD stays in your system. To understand that, we need to explain the concept of “half-life”.
What is half-life?
Half-life is the term used to measure the amount of time it takes for a compound to be reduced to half its original amount or effectiveness in the body. It’s gauged by measuring blood plasma for metabolites of the compound in question. From the plasma, drug metabolites are either removed from the body or translocated to another type of bodily fluid.
Half-life is typically measured by administering a single dose of a compound, then testing blood plasma for traces of the drug at regular intervals. The amount of the drug in the plasma will usually increase, reach a peak, and then start to decline.
Using the information obtained while measuring CBD’s half-life, scientists can work out how long CBD stays in the body. You cannot do this yourself at home, but we can use their data to provide a general timeframe.
How long does CBD stay in your system?
The exact half-life of CBD isn’t 100% clear, but we can explore some of the existing studies. There’s evidence that suggests that CBD has a half-life of roughly 2–5 days. This is based on a study involving 14 patients with Huntington’s disease. The patients were given doses of around 700mg of CBD per day for 6 weeks. Note that these doses are much higher than a standard recommended dose.
In another study, half-life of CBD was evaluated based on a single dose in the amount of 20mg and 18.8–19.4mg administered intravenously and smoked respectively. The half-life was accordingly estimated at 18–30h and 27–35h.
But, and this is an important but, that timescale will vary from one person to the next. How long CBD stays in your system is also affected by several biological factors, as well as the way you consume it.
As a general rule of thumb, the more efficient the consumption method, the faster CBD is processed, and the quicker it leaves our system. So, back to our earlier example, orally consumed CBD should stay in your system longer, compared to sublingual application or vaping. It’s a delicate balancing act, but one that you’ll need to experiment with to find out what works for you.
What affects the half-life of CBD?
Whenever talking about the metabolism of any compound, it’s essential to realise that everyone’s body is a little different, and several biological factors can influence your ability to process compounds such as CBD.
CBD is fat-soluble, so a small portion may get stored in fat cells. The cannabinoid can stay in your system for a little longer if you have a high body fat percentage.
• Efficiency of your metabolism
Our metabolism is a combination of chemical reactions, one of which includes the conversion of food to energy. The faster your metabolism, the quicker substances (including CBD) are broken down, processed and eliminated.
• Method of consumption
How you consume CBD not only alters the potency but the duration of effects. The method of consumption also goes hand in hand with bioavailability. Generally speaking, administration methods with greater bioavailability will also leave your system faster.
• Amount of CBD consumed
The more CBD you take, the longer it takes for your body to process it. Be careful though, high doses may produce mild side effects, so it’s essential to find what works for you.
• Purity and strength of the oil/supplement you’re using
The higher the concentration of a CBD oil or supplement, the longer it takes your liver to process, and the longer active ingredients stay in your system.
How long does CBD stay in your system—bottom line
CBD is a very unique and complex compound that can affect everyone slightly differently. Unfortunately, studies have not yet been able to pinpoint the exact half-life of cannabidiol. The half-life of CBD can be estimated to be between 18 and 35 hours, while other studies suggest that the half-life of CBD could be up to 5 days.
However, remember that these are ball-park figures. As we mentioned earlier, a lot of different factors can influence the rate at which your body processes and metabolises compounds like CBD. Until further studies look into the half-life of cannabidiol, these figures are the closest we’ve got.

How long does CBD last? Learn about effects, detectability, half life, and more
CBD’s relation to THC often makes people wonder whether it is detectable in drug tests. Do drug tests screen for CBD? How long does CBD stay in your system? What is CBD’s half life? And how long do the effects of CBD last? The answer to these questions will depend on a few factors, and since CBD has no psychoactive properties it’s not always easy to figure out the effects yourself.
If you’re confused, use this article: we give you the important points on
- How long CBD stays in your system
- CBD detectability in drug tests
- Different methods of consumption.
How long does CBD stay in your system?
One study estimated CBD half-life at 1-2 days , so a moderate dose of CBD will typically be out of your system within 3-4 days of initial consumption, with a maximum of one week . However, the science is not definitive on how long CBD stays in your system, and there are a number of influencing factors.
Very high doses will stay in your body longer, and your height, weight, and metabolism will also influence how long CBD stays in your system. Generally speaking, the faster your metabolism and the lower your body weight, the quicker CBD will be out of your system.
Is CBD detectable in drug tests?
No , drug tests do not screen for CBD, so you don’t have to worry about how long CBD is detectable in urine. Drug tests only screen for THC and its related metabolites in urine, blood, or hair.
BUT, there’s something else to keep in mind: there are cases of people using only CBD oil testing positive for THC metabolites in drug tests. This is likely due to CBD products that contain trace amounts of THC. One way to avoid this is to check the label of any CBD product you buy for a guarantee that it is THC-free.
CBD oil vs. Hemp oil vs. THC oil: what’s the difference?
CBD oil is an oil that contains concentrated cannabidiol, or CBD, which is extracted from the leaves and stem of the hemp plant. CBD oil is non-psychoactive, and is a powerful anti-inflammatory that provides a range of medical benefits.
Hemp oil is a seed oil made from the seed of the hemp plant, and is commonly used in cooking. While hemp oil is highly nutritious, it does not contain CBD or THC, and does not have medicinal properties.
THC oil contains concentrated THC and little/no CBD, so it has the psychoactive properties of marijuana, but fewer medical benefits than CBD.
How should you take CBD?
CBD can be taken both topically and orally. If you are using CBD for joint pain, muscle soreness, or skin problems, then you apply a topical balm or lotion directly to the body part.
If you are taking CBD for pain, anxiety, or to reduce chronic inflammation, then you should take it orally. There are a number of ways you can do this:
- Vape oil
Tinctures are the fastest-absorbed oral method. While vaping CBD oil also works quickly, the effects of CBD last longer when ingested orally.
You shouldn’t have to worry about exactly how long CBD will stay in your system, since:
- You’re virtually guaranteed to never get drug-tested for CBD
- The effects only last a few hours
- CBD has a relatively short half life.
Either way, rest assured that your body will likely expel it within a week or so.
How quickly does CBD oil work?
Your body reacts to CBD within 30 to 40 minutes of ingesting it orally, so it should start working within an hour at the most. If you ingest CBD on an empty stomach, it will work quicker.
How long do the effects of CBD last?
The effects of CBD typically last 5-6 hours . However, it depends on the dose and type of CBD. The effects of pure or refined CBD oil will last longer. Once it is initially absorbed, the concentration of CBD in the blood drops hour-by-hour, so larger doses will also last longer.
Can you feel the effect of CBD?
CBD has no psychoactive properties, so you will not get high, experience euphoria, or feel a mental effect. However, you will absolutely feel the effect in terms of relief from pain, anxiety, seizures, inflammation, and much more. CBD also has relatively few side-effects, with people only rarely experiencing minor effects like nausea and lethargy.
Does CBD oil go bad?
Yes, CBD oil does expire, so you should check the expiration date on your bottle. Typically, CBD oil will last 1-2 years , as long as it is stored in a cool, dry place.
