We've answered 'how long do the effects of CBD last?' 'how long does CBD stay in your system?' 'What does CBD feel like?' and more! Answering this question isn’t as simple as it may seem, as CBD reacts differently for everybody – from the time it takes to kick in, the amount you’ll need to Consuming CBD may have many potential health benefits, which explains its popularity. We break down the factors that impact how long CBD stays in your system.
How Long Do the Effects of CBD Last? How Long Does CBD Stay in Your System?
CBD has taken the UK health and wellness industry by storm with many reported health benefits from chronic pain, anxiety and even skincare! However, there’s still a lot of confusion and misinformation around cannabidiol. One of the most commonly asked questions we get asked here at ULU is, ‘how long do the effects of CBD last?’ or even, ‘how long does CBD last?’
The answer to this questions depends on a number of factors. So firstly, we’ll talk about how method of consumption, dosage, body weight and lifestyle affects how long CBD lasts in the body.
Next, we’ll cover the question, ‘what does CBD feel like?’ as well as ‘how long do the effects of CBD last?’ Then, we’ll go on to cover ‘how long does CBD last on the shelf?’ ‘How long does CBD oil last before it runs out?’ and end with ‘Will CBD show up on a drugs test?’
How long does CBD last in the body?
Firstly, it’s really important to note that everyone is different when it comes to CBD (cannabidiol). In general, the effects of CBD will last in the body for around 2-8 hours. However, there are lots of different factors that affect how quickly cannabidiol becomes absorbed into your body, and how long it will last. It also depends on the person taking the CBD!
So, let’s take a look at some of these factors that affect how long the effects of CBD will last in the body.
Methods of consumption
There are so many different ways to take CBD nowadays! In fact, you can find almost any CBD product to suit any need! However, you should understand that different CBD products come with different benefits , but also different characteristics. The method of consumption you choose can actually affect how long CBD stays in your system.
Below, we’ll take a look at 4 common ways of taking CBD. For each of these CBD products we’ll discuss what happens when they enter your body and answer the question, ‘how long does CBD stay in your blood or in your system?’
CBD capsules are a favourite method of consumption among people who already take a daily multivitamin. They’re clean, easy to transport and easy to use!
However, just like any supplement taken in tablet form, it takes a while to become absorbed into your body. This is because the cannabidiol needs to pass through the digestive system and the liver where it is metabolised by the enzymes in your body. This both reduces the concentration of CBD and also leads to a delay in onset of effects.
So, it can take up to 60 minutes to feel any effects from CBD capsules, however the effects can last for 6-8 hours. This is also how long the CBD capsules will stay in your system.
CBD oil is perhaps the most popular CBD method of consumption in the UK. They’re also incredibly easy to consume – simply use the oil dropper to place 2-3 drops of CBD under your tongue and then wait 60 seconds for it to become absorbed.
So, what happens next?
Well, when you take cannabidiol oil sublingually, (under the tongue) it’s actually able to bypass the digestive system. This means that it will become absorbed into the body’s bloodstream within 30 minutes to an hour. So, then how long does CBD oil stay in your blood?- It should stay in your system for around 2-4 hours.
CBD vapes are the quickest way to get CBD into your system. You simply inhale the cannabidiol vapour using a compatible vaping device. Once again, this method of consumption allows CBD to bypass the digestive system and quickly enter the bloodstream for almost immediate effects.
Your lungs are able to quickly absorb the cannabidiol, so you could feel the effects within minutes – but then how long does the CBD stay in your blood? Well, due to the quick uptake into the system, the effects of vaping CBD will only last for around 30 minutes to an hour. This makes vaping CBD a great option for short-term support with anxiety symptoms as a fairly immediate relaxant.
Topical CBD products are designed to be applied externally – usually to the skin or hair. They also come in many different forms such as creams, ointments and oils.
So, how long do CBD effects last for topically applied products – and how long will it take to notice an effect?
Well, topical CBD products are absorbed though the skin. This means that the cannabidiol is able to bypass the digestive system and is able to get to work locally. It will take around 2 hours to feel the effects of CBD skincare and this will then last for around 5 hours or more before.
Whilst Topical CBD does not enter your bloodstream, it is able to target Endocanabinoid receptors in the skin which unlock the benefits of your body’s Endocannabinoid System. Learn more about the Endocannabinoid System and why it’s so important to your health!
Doses of CBD
In addition to method of consumption, the doses of CBD, or the amount of CBD you take will also affect how long it stays in your bloodstream or your system as a whole.
As a rule, the higher the dose of CBD you consume, the longer it will take for your body to process and metabolise it. However, there’s no exact measurement for this, as the results really do vary from person to person.
How much CBD should you take?
The amount of CBD you take depends on a number of factors including body weight, lifestyle and the health benefits you’re looking to receive.
As with any supplement, the higher your body weight, the more you will need to take. This is also affected by your fat and muscle percentage.
In addition, different doses of CBD are better suited to different heath issues. For example, if you’re looking for support with a long-term chronic issue such as inflammation, anxiety, chronic pain or depression, you’ll need to take a higher dose of CBD. On the other hand, for short-term, more immediate relaxation, a few puffs of a CBD vape are likely to help.
Whilst optimum doses of CBD vary from person to person, we recommend starting small. You should begin with around 5-10mg of CBD (regardless of product type) 1-2 times a day, every day for a week or two. Then, if you haven’t noticed any benefits, slowly increase the dose over the next few weeks.
Don’t worry, you can’t overdose from CBD! However, it’s best to take things slow to find the CBD dose that works best for you. As a rule, you should never take more than 70mg of CBD per day unless instructed otherwise by your doctor.
Body weight is another one of the main factors that affect how long CBD lasts in the the body. This is because CBD is fat soluble and is stored in the body’s fat cells.
This means that if you have a higher body fat percentage, CBD will stay in your system for longer. You’ll also feel the effects and benefits for a longer period of time.
In addition, how long CBD stays in your system is affected by your metabolic rate. If you have more muscle than fat in your body, you’ll have a higher metabolic rate. Therefore substances like CBD will be processed much more quickly and will leave the body sooner than someone with a lower metabolic rate. You’ll also feel the effects for a much shorter period. This means that people with a higher muscle to fat ratio will need to take higher doses of CBD.
Lifestyle is another of the factors that affect how long CBD stays in your system. For example, if you lead an active lifestyle, your metabolism and your metabolic rate will usually be higher than someone leading a sedentary lifestyle. As we’ve already mentioned, this means that your body will process and metabolise CBD more quickly.
What does CBD feel like?
It’s important to understand that CBD is classed as a non-rewarding, non-psychoactive substance. This means that it does not cause a high or any kind of intoxication.
Some users report an immediate feeling of relaxation when using CBD. However, in general the short-term effects are very subtle. CBD works by targeting your body’s Endocannabinoid System – a complex cell-signalling system responsible for maintaining homeostasis in the body. So, when you take CBD it replenishes your body’s cannabinoid levels and keeps your ECS working optimally.
This process works over a long-term basis, so it can take a few weeks to see noticeable benefits and effects from CBD. However, this again depends on all of the factors we discussed previously: method of consumption, dose, body weight and lifestyle.
For example, vaping CBD enters the bloodstream more quickly, so many users report a more immediate effect of calm or relaxation. In addition, CBD rubs and salves have been linked to short-term benefits for chronic pain and muscle aches. The feeling of CBD capsules or oils is much gentler, building up over a longer period.
It’s important to stress that you’ll need to be patient when it comes to taking CBD. Many people expect to feel an immediate effect and are disappointed when this isn’t noticeable. In addition, many people stop using their CBD product after a few days because they haven’t noticed any benefit.
However, CBD actually works very subtly. Furthermore, depending on your chosen product, dose and lifestyle can take a few weeks to start having noticeable benefits. So, as we’ve already mentioned, keep going with your initial dose for at least a week. Then, if you can’t feel or notice any benefits, slowly increase the dose over the next few weeks.
As long as you’re taking a high-quality CBD product regularly, over a long-term period and at a high enough dose for your body weight and lifestyle, you are likely to notice some benefits.
How long do the effects of CBD last?
Regardless of the type of cannabidiol product you’ve used, how long you’ve been taking CBD also plays a role in how the CBD effects last.
If you use a single dose of any CBD product, the cannabidiol will only stay in your system for up to around 8 hours and the effects will last about the same amount of time. However, what happens if you’ve been using CBD for a few weeks or even months? How long do CBD effects last in this case?
Well, once again, this depends on your body, your lifestyle and the dose you usually take. However, CBD takes a few weeks to start working with your Endocannabinoid System. This means that any benefits and effects will take a while to build up in your body. Therefore, the longer you’ve been taking CBD, the longer it will take for the benefits to completely subside. However, long-term CBD users have reported that the effects of CBD start to subside after only a few days of stopping their regular dose.
How long does CBD last on the shelf?
Unlike other consumable items, the best before and sell by dates of CBD products are not regulated in the UK. Therefore, it’s up to the retailer to recommend expiry dates for their cannabidiol items. So, always make sure to check retailer guidelines carefully to ensure product freshness.
However, in general, how long a product lasts depends on how you store it, as well as the quality of ingredients.
CBD products need to be stored at room temperature and out of light. This is because all types of light can lead to significant cannabinoid degradation. You should also keep your CBD product sealed with the lid firmly tightened to avoid oxygenation.
How long does CBD oil last before it runs out?
Another concern for UK consumers is, ‘how long does a bottle of CBD oil last?’ CBD can be expensive. Therefore, it’s natural that customers want to know how many uses they’ll get out of a standard CBD oil bottle.
Again, this can vary from retailer to retailer. It also depends on CBD concentration (amount of CBD per drop) and product contents (number of drops per bottle.)
To work out how long a bottle of CBD oil will last you’ll need to work out these simple factors:
- How many mg of CBD are in the bottle as a whole?
- How many mg of CBD are in 1 drop of CBD oil?
- How many mg do you intend to take per dose / how many drops of CBD per dose?
- How many doses of CBD do you take per day?
- Then, divide the total mg of CBD per bottle by your mg per dose
- I buy a bottle of CBD oil with total 2000mg of CBD
- Each drop of oil contains 1mg of cannabidiol
- I want to take 10mg of CBD per dose
- I want to take 2 doses per day. This is 20mg total and 20 drops.
- 2000mg divided by 20mg is 100.
- Therefore, this bottle of CBD oil will last 100 days
Here at ULU, we always publish our mg of CBD per drop and total mg of CBD in every bottle. So, you can easily work out how long our products will last!
Will CBD show up on a drugs test?
A major concern for many UK customers is ‘will CBD show up on a drugs test?’ After all, nobody wants to be caught out by failing a drugs test accidentally.
The short answer here is that no, CBD products will not show up on a drugs test and will not cause you to fail, but let us explain a bit more about why that’s the case:
In the UK, drug tests are designed to look for metabolites of illegal drugs – the chemicals that are left behind after a drug is broken down by the body. This can be done by testing blood, urine, hair, sweat or saliva. Different companies will test for different drugs, but the most common package is a urine test for cannabis, cocaine, amphetamine, methamphetamine, benzodiazepine and opiates.
Whilst CBD comes from hemp – a plant within the cannabis family, UK drug tests for cannabis are actually looking for metabolites of THC – an illegal, psychoactive cannabinoid found within cannabis plants like marijuana.
So, if you’re wondering ‘will CBD show up on a drugs test?’ The answer is no! However, only as long as you’re buying CBD products from retailers that can guarantee less than 0% THC content.
Phew! There was a lot of information to take in here! So, let’s summarise the answers to the most important questions in this article:
So, how long does CBD stay in your system? – The length of time that CBD stays in your system depends on a number of factors including product type, method of consumption, body weight, dose and lifestyle.
how long will CBD stay in your blood? – Not all methods of CBD consumption will enter the bloodstream. CBD oils and vapes ensure that cannabidiol becomes absorbed into the bloodstream and will stay in your blood for up to 2 hours (vapes) and 4 hours (oils). However CBD capsules are absorbed into the digestive system and CBD topicals are absorbed by Endocannabinoid receptors in the skin.
What does CBD feel like? – Some users report an instant feeling of calm. However, in most cases, CBD users don’t feel any immediate effect. They do however notice long-term benefits for mental and physical health.
How long do the effects of CBD last? – This also product type, body weight, dose and lifestyle. It also depends on how long you’ve been taking CBD. For a single dose, the effects of CBD will last for only a few hours. However, if you’ve been taking CBD for a few weeks or months and you stop, it can take a few days for the effects to wear off.
How long does CBD last on the shelf? This varies depending on manufacturer, so always remember to check individual product information!
Will CBD show up on a drugs test? Nope! As long as the product contains less than 0% THC you won’t fail a drugs test.

How long do CBD effects last?
Answering this question isn’t as simple as it may seem, as CBD reacts differently for everybody – from the time it takes to kick in, the amount you’ll need to experience certain effects, and how long the effects last before you have to dose again.
After deciding on the dosage you need for the ailment you’re treating, you must then work out how you want to intake the CBD – in the past smoking was pretty much the only option, but now you can vape, consume edibles, take sublingual sprays, apply creams and more.
In this post, we will go over the main CBD consumption methods, and how much CBD is typically required for each of these. We’ll also talk about the general effects felt after CBD gets to work in your system.
How can I consume CBD?
We won’t go over smoking CBD, as it’s self-explanatory and the least healthy way to take CBD due to the carcinogens and other toxic byproducts inhaled from the smoke. If you are a non-smoker, there’s no upside to smoking over other methods.
Vaping is the quickest way to get CBD into your bloodstream, and the effects will begin to take hold after a matter of minutes. If you plan on vaping, you’ll need a vaporizer that’s suitable for the CBD product you want to vape. While CBD kicks in rapidly through vaping, the effects do tend to be short lasting, with most reporting two or three hours of relief before having to re-dose.
CBD sublingual sprays
Some choose to drip CBD oil under their tongue, hold it for a minute or two and then swallow – this is known as sublingual consumption. This is another speedy way of taking CBD, with the therapeutic reactions in full swing after just 20 to 30 minutes. Effects tend to last anywhere between four to six hours. Tinctures, which involves dripping CBD oil under the tongue with a pipette, and sprays are the most common sublingual spray products.
CBD edibles and capsules
Making tasty edibles with marijuana is a favorite for stoners, but medical CBD users can also benefit from this intake method. While you could make CBD brownies and cookies yourself, various gummy bears, lollipops and other CBD candy products are also available nowadays. It’s best to take CBD edibles on an empty stomach as this helps speed up absorption. For those after more traditional consumption, CBD capsules are discreet and work just as well as standard edibles.
A quick metabolism and healthy digestive system also help deliver a successful medicating experience with edibles. Get everything right, and there’s no reason why you can’t be feeling the effects in just half an hour – with a poor set-up, edibles can sometimes take as long as two hours to start working. Capsules tend to take an hour to fully kick in, since the capsule first has to be digested before the CBD can be released and absorbed into the bloodstream. Both edibles and capsules last for around four to six hours on average.
Applying CBD topicals
Various creams, balms and salves designed for topical application are sold here at CBDVapeJuice.net. These are ideal for treating localized, chronic pain as one can simply apply to the affected area (e.g. stiff joints) and allow the magic to work. CBD is also an excellent compound for the skin, protecting from free radical damage which can incredibly help to slow the ageing process by preventing wrinkles. Sufferers of acne, eczema, psoriasis and other skin complaints may also find joy through CBD topicals.
These do take longer than other methods to work, often over an hour, but the effects are also longer-lasting – users report up to six hours of relief.
How much CBD is enough?
There’s no one answer as everybody has different CBD tolerances and is consuming it for their own reasons – for example, somebody suffering with an inflammation condition would likely need more than somebody with mild anxiety. Couple that with body size, metabolism speed and other variable factors, and it really is a case of experimenting until you find a happy medium.
Naturally, if you’re inexperienced with CBD, start off with low doses and read how your body responds before upping the potency. Continue to do this until your symptoms have gone away, or are at least more manageable.
CBD is non-addictive and there’s no potential to become physically dependent on the compound either. Studies have shown that the body can safely handle enormous quantities of CBD (at least 1,000mg) daily.
However, vast quantities of CBD can leave the body feeling very sedated, so if you do plan on a hefty medicating session, ensure you’re in a relaxing environment – don’t attempt to drive or handle heavy machinery when in a relaxed, and perhaps slightly drowsy state.
How to tell if CBD is working for you
Guess what? This is another question that is difficult to answer! If you’ve never taken CBD before, you’ll have no idea what to expect. Since there is no ‘high,’ you may not realize when the dosage is effective. It tends to provide a subtle feeling. If you take CBD for pain, you may eventually realize that the pain has gone, but it might take time for you to understand what has happened.
Once again, each person is different and it’s hard to explain the exact sensations of CBD to someone who hasn’t consumed it before – it really is a unique experience. However, it’s not like when you take THC-laden cannabis, as there are no psychoactive properties in CBD, and therefore it cannot induce a high, no matter how much you take. Many find CBD’s effects to be rather subtle. For example, when using for pain relief, the pain won’t disappear at a precise moment – instead, the relief is much more gradual.
This is also the case when treating anxiety with CBD. Depending on how you’ve consumed it, the effects will slowly become more apparent with time – in this case, CBD will leave you increasingly calmer. Therefore, don’t go into a CBD experience expecting instant relief, as you may feel underwhelmed. Just relax, forget about the time, and reassess your symptoms around an hour or two after consumption.
Final thoughts on CBD
Despite having no official medical use yet in the United States, CBD is being used to treat a whole range of conditions and symptoms, including chronic pain, inflammation, PTSD, depression, insomnia, anxiety, Multiple Sclerosis and more. State laws surrounding CBD are typically more relaxed than laws for marijuana and its other derivatives, as CBD is non-intoxicating.

- How Long Do the Effects of CBD Oil Last?
Research shows consuming cannabidiol (CBD) may have a host of potential health benefits, such as reducing anxiety, relieving pain, and promoting sleep—explaining the latest surge in CBD’s popularity. But people who use CBD—either regularly or just once in a while—might wonder how long it stays in your system.
No matter how you take CBD, it’s likely that the clinical impact can last for several days after use, says Kelly Johnson-Arbor, M.D., a triple-board certified medical toxicologist and co-medical director of National Capital Poison Center. In fact, a 2020 study in the Journal of Analytical Toxicology found people who consumed a single dose of a standardized CBD formulation had detectable levels of CBD in their urine for four to five days after ingestion  Spindle T, Cone E, Kuntz D, Mitchell J, Bigelow G, Flegl R, Vandrey R. Urinary Pharmacokinetic Profile of Cannabinoids Following Administration of Vaporized and Oral Cannabidiol and Vaporized CBD-Dominant Cannabis. Journal of Analytical Toxicology. 2020;44(2):109-125. .

5 Factors That Affect How Long CBD Stays in Your System
According to Dr. Johnson-Arbor, how long CBD stays in your system can depend on various factors.
How and What You Eat
How much you eat, as well as what you eat, can impact how your body processes CBD, says Dr. Johnson-Arbor. After consuming a high-fat meal, higher levels of CBD are typically present in the bloodstream, making its half-life (the time it takes for half the amount of a substance to be eliminated from the body) longer than in individuals who consume CBD while fasting, she explains. In other words, if you consume CBD on an empty stomach and don’t eat immediately, CBD is more likely to leave your system sooner. Meanwhile, eating high-fat foods, such as avocados, cheese and nuts, can have the opposite effect. One 2019 study also found CBD exposure and absorption increases significantly when paired with high-fat foods  Birnbaum A, Karanam A, Marino S, Barkley C, Remmel R, Roslawski M, Gramling-Aden M, Leppik I. Food Effect on Pharmacokinetics of Cannabidiol Oral Capsules in Adult Patients with Refractory Epilepsy. Epilepsia. 2019;60(8):1586-1592. .
Medications Processed in the Liver and Liver Disease
Certain medical conditions may impact how long CBD stays in your system. “Since CBD is metabolized by the liver, people with liver disease or who take other medications that are metabolized by the liver may have altered metabolism of CBD,” says Dr. Johnson-Arbor. She explains that the human liver contains enzymes that help the body break down medications and other compounds, and some medications can increase or decrease the activity of these enzymes. “When this happens, medications can be metabolized either faster or slower than normal, and this can lead to unwanted adverse reactions,” she says. Since CBD is metabolized by liver enzymes, there can be a potential drug interaction with many other medications.
Frequency of Use
If you use CBD frequently, it can build up over time and stay in your system longer, largely because CBD is highly soluble in fat. “This means that it can build up in our fatty tissues for a long period of time after heavy use and can therefore remain in the system for prolonged periods of time (e.g. weeks) in heavy users,” says Dr. Johnson-Arbor.
How Much You Use
Unsurprisingly, the more CBD you take at once, the longer it stays in your system. A 2005 study in the journal Therapeutic Drug Monitoring found taking 1.35 milligrams of CBD was only detectable in the blood for about six hours after ingestion, but higher doses were detectable for longer periods of time  Nadulski T, Pragst F, Weinberg G, Roser P, Schnelle M, Fronk E, Stadelmann A. Randomized, double-blind, placebo-controlled study about the effects of cannabidiol (CBD) on the pharmacokinetics of Delta9-tetrahydrocannabinol (THC) after oral application of THC versus standardized cannabis extract. Therapeutic Drug Monitoring. 2005;27(6):799-810. .
Type of CBD Administration
The way in which you consume CBD can impact how long it stays in your system. According to a 2018 review, smoking or inhaling CBD not only causes CBD to enter the bloodstream faster but also leave the body quicker. Meanwhile, the same review found CBD oil can stay in your system longer—up to two to five days. Dr. Johnson-Arbor explains that the reason smoking or inhaling drugs leads to faster clinical effects than consuming a drug orally is because orally administered drugs have to be absorbed through the gastrointestinal tract, and that takes more time. However, whenever you’re talking about how long CBD can stay in your system, it’s important to remember that it really depends on the frequency of use. “CBD (and other cannabinoids) are fat soluble, which means that they can accumulate in fat tissue after chronic use and then be released back slowly into the blood for elimination from the body,” she says. “This means that chronic users may have longer detection times than acute or one-time users (the latter is what’s generally represented in clinical studies and may not be applicable to the general population). The same is true for smoking and inhaling CBD. I don’t want people to get the wrong impression and believe that no matter how much or how frequently they use, CBD will only be detectable in their system for two to five days.”
How Long Do the Effects of CBD Oil Last?
How long the effects of CBD last varies greatly depending on the factors discussed above. “In a study involving healthy individuals who consumed a highly purified CBD formulation, the elimination half-life in the bloodstream was 14 to 17 hours. Since it takes approximately five half-lives to completely eliminate a drug from the human body, it’s likely that CBD stays in the system for about 85 hours, or about 3.5 days” says Dr. Johnson-Arbor.
So, based on the half-life of the drug, it’s likely that detectable levels may be present for several days after use.
