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.
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 Does CBD Last?
People have a lot of questions about CBD. One of the most common questions we hear:
How long do the effects of CBD last?
It’s a great question! And anyone interested in taking CBD deserves to know the answer. No matter what your reason for taking CBD, you obviously want to know how long the effects are going to last. Who wouldn’t? We’re here to clear this up once and for all.
How Long the Effects of CBD Last: What You Need to Know
One of the first things to understand about how long CBD effects last is that CBD affects everyone differently. How long it takes to feel the effects and how long these effects are experienced depend a lot on the person who is taking it.
That being said, there are a couple general things to keep in mind when determining just how long CBD effects will last.
If You’re New to CBD, Give it Some Time
If you’re new to CBD and you’re wondering how long the effects of CBD last, you’ll want to give your body some time to adjust to taking it. Many people just starting out on their CBD journey try it for the first time and think they’re going to immediately see extraordinary results, but this isn’t always how CBD works.
Maybe for some it does (and we love hearing these stories), but remember that CBD affects each person differently. It’s best to give your CBD regimen some time before determining how long various methods work for you.
How You Use CBD Determines How Long it Takes to Feel the Effects and How Long the Effects Last
There are several different ways to take CBD and the method you choose will ultimately determine how long the effects last. While there is the option of CBD flower, which can be smoked or vaped in several medical marijuana dispensaries, most individuals who use CBD favor products made with CBD oil.
How long it takes CBD to work, as well as how long the effects last, will differ. As a general rule, CBD effects will last between 2-8 hours.
Some of the most popular methods of using CBD (including how long it takes to feel the effects of each and how long these effects last) include:
Tinctures are one of the most popular ways to enjoy CBD. CBD tinctures are taken most effectively by mouth — many people will hold it there for one to two minutes before swallowing.
It typically takes 15–30 minutes to feel the effects of a CBD tincture, and the effects are known to last between 4–6 hours.
CBD capsules are taken just like a regular supplement. When CBD is ingested orally this way, it must first pass through the digestive system and then the liver, where CBD molecules are metabolized by various enzymes. This is something that reduces the concentration of CBD compounds that are then passed into the bloodstream. Because CBD must pass through both the digestive system and the liver, it takes longer to feel the effects.
It can take up to one hour to feel the effects of capsules, which usually last between 6–8 hours.
CBD edibles and beverages work much like CBD capsules. When CBD is consumed in the form of CBD gummies or infused hard candies, chocolates, drinks or other edibles, it must pass through the digestive system and the liver.
Many people who take CBD in the form of capsules, edibles or drinks prefer to do so on an empty stomach, which can reduce the time it takes for CBD to make its way through the digestive tract and be broken down by the liver. However, consuming capsules or edibles with fatty-acid-rich foods may help increase bioavailability.
Like capsules, it typically takes up to an hour to feel the effects of edibles or beverages, and the effects last between 4–6 hours. (Also see our excellent CBD gummies guide for additional information)
CBD topicals are applied directly to the skin, coming in the form of lotions, creams, balms and salves. CBD topicals are excellent for providing localized benefits to the area of the body to which they are applied. They are absorbed through the skin, bypassing the digestive tract completely.
Research indicates the presence of an endocannabinoid system in the skin, which has been associated with several biological processes. Because CBD topicals bypass the digestive tract and liver, the effects can be felt much quicker than when using other methods.
Generally, CBD topical effects can be felt within 15–20 minutes and can last for up to 6 hours.
Vaping CBD oil is generally the quickest way to feel the benefits of CBD. When you vape CBD, your lungs quickly absorb the CBD you inhale. From here it quickly enters the bloodstream, where it then travels to various parts throughout the body.
The effects of vaping CBD are felt almost immediately but don’t last as long as other traditional products. The effects of vaping CBD are expected to last around 2–3 hours.
How Much CBD Should You Take?
Now that you know how long the effects of CBD last, you might be wondering just how much CBD you should take to feel these desired effects. Remember, CBD affects everyone differently and ideal servings will vary tremendously. Like we mentioned before, the best thing you can do is give it some time.
When you first start taking CBD, it’s best to give your body time to adjust to something new. Start by slowly by taking a low serving size (5–10mg) and then work your way up over the course of a couple weeks until you hit that sweet spot and feel the benefits you desire.
CBD works differently for everyone, which will ultimately determine how long the effects last for them personally. The type of CBD product and how you use it also has a significant influence on how long the CBD effects last. Generally speaking, depending on what type of CBD product you’re using, the effects will last between 2–8 hours.
