Bottom line: Whether you’re ingesting CBD oil or CBD-infused edibles, it ultimately goes through the same lengthy digestive process, reducing the total CBD concentration in the bloodstream. With ingestion, it could take anywhere from one to two hours before the effects of CBD finally set in. From there, you may feel the effects for one hour to several hours, depending on the dose and your response to CBD.

In most cases, it’s highly unlikely that CBD will cause a positive test result in a drug screening. Most drug tests are developed to look specifically for the presence of THC or related substances. On top of that, employers generally abide by the Substance Abuse and Mental Health Services (SAMHSA) guidelines, which include detection for THC but not CBD.

Inhalation is also an effective delivery method for CBD due to its rapid absorption and the efficiency of the lungs at transferring CBD into the bloodstream. Whether you’re smoking a high-CBD strain or taking a draw from a CBD vape pen, the interaction with the body remains the same. When CBD is inhaled, the cannabinoids are sent directly to the lungs, where they are rapidly absorbed into the bloodstream and put into circulation.


The consumption method plays a crucial role in determining how long it will take to feel the effects of CBD and how long they will last.

It’s important to note that, while existing evidence shows us that CBD can definitely be detected in the body for a certain period of time, most drug tests specifically look for the presence of THC. Therefore, accurate information on how long CBD stays in the body remains limited compared with information on THC.

Studies show that when the liver metabolizes CBD compounds, they undergo what is called the “first-pass effect.” Enzymes in the liver reduce CBD concentration before the remainder is finally sent to the bloodstream and circulated throughout the body. While oral consumption of CBD has become popular for its ease of use, it can be an inefficient method of consumption compared with inhalation or sublingual administration. This is because only about 5% of swallowed CBD ends up in the bloodstream, meaning this method provides low bioavailability.

A 1991 study published in Pharmacology Biochemistry & Behavior examined the concentration of CBD in the blood after high doses daily. Over a six-week period, the research team administered a daily dose of 700 milligrams of CBD to 14 Huntington’s disease patients. One week after the dosing ceased, the CBD remaining in the blood was just 1.5 nanograms per milliliter and was “virtually undetectable” thereafter.

Bottom line: While the time that CBD is detectable in the body will depend on the aforementioned factors, we can deduce that CBD will likely leave the system after a week or two.

Swallowing CBD oil prevents the cannabinoid from entering the bloodstream right away. Instead, it will travel first through the digestive tract and eventually on to the liver, where it will be broken down before finally reaching the bloodstream.

Bottom line: Existing evidence suggests that CBD reaches peak blood concentration within three minutes after inhalation, meaning any effects should be felt shortly after use. The effects should then last anywhere from 45 minutes to a couple of hours.

Bottom line: Apart from the one study that showed CBD was no longer detectable in urine after 24 hours, there isn’t much research on drug testing for CBD in urine.

Oral ingestion is the most common method of CBD consumption. Administering a couple of drops of CBD oil directly into the mouth is certainly a convenient way to reap the potential benefits of this therapeutic cannabinoid. However, ingestion is not necessarily the most effective consumption method for those who want to feel the effects of CBD immediately.

The sublingual method is considered to be more effective than ingestion. CBD oil can be consumed sublingually by placing a few drops under the tongue and holding it for two to four minutes, then using the tongue to rub it into the tissue under the tongue and on the inside of the cheeks before swallowing the remainder. Using this method, CBD is transferred to the bloodstream via the mucous membranes located in the mouth, completely bypassing the digestive system and liver.

Cannabidiol (CBD), a non-intoxicating compound found in the cannabis plant, may potentially relieve mild pain and anxiety. While many people are using CBD for these potential benefits, the fear of failing a drug test looms large for others. Because even with the legalization of hemp-derived CBD products in the US, there’s still some uncertainty about how CBD interacts with the body.

Consumers who want to be extra-cautious and use CBD with no THC should shop for a broad-spectrum oil or a CBD product that contains pure CBD isolate. Broad-spectrum oil is refined to exclude THC, while CBD isolates contain no THC or other plant-based cannabinoids. To ensure that your CBD contains no THC, it’s important to source products from reputable manufacturers that provide a certificate of analysis from a third-party testing lab.

We have some insight into how long CBD remains in the blood, but there is little research on how long CBD is detectable in urine. In a 2016 study published in the Journal of Pain, participants were given different types of CBD-rich cannabis products, including oils, capsules, and flower. Two hours after administration, urine samples from all 15 subjects tested positive for CBD. The researchers followed one participant after the last day of administration and found that CBD was no longer detectable in the urine after 24 hours.

Here, we’ll cover the existing research on CBD and its interaction with the human body as well as what factors can affect how long CBD stays in your system.

Based on existing research, CBD may stay in your system anywhere from 24 hours to a few weeks. That timeframe can change depending on a variety of factors including metabolism, consumption method, frequency of use, and dosage.

Keep in mind that even hemp-derived CBD products are legally allowed to contain up to 0.3% THC. This could cause hesitation for some CBD-curious consumers who don’t want THC in their system or risk a false positive result on a drug test. However, the chances of failing a drug test from using hemp-extracted CBD oil are extremely slim. You would need to take an exorbitant dosage of full-spectrum CBD oil (estimates range from 1,000 to 2,000 milligrams per day) to risk a positive drug test result.

Bottom line: Consuming CBD products sublingually leads to higher bioavailability compared to consuming CBD products orally. Depending on the dose and your response to CBD, the effects from sublingual consumption should kick in within 30 minutes and last for one to three hours.

CBD may not produce the same intoxicating effects as THC, but it does get stored in the body. The time that CBD remains detectable in the body depends on several factors.

Most topicals stay at skin and muscle level without entering the bloodstream, meaning the CBD (and any THC it contains) will not be in your system at all. Transdermal patches are placed on one of your veins, so cannabinoids may enter the bloodstream. CBD remains in the system for approximately 2-5 days when delivered via these patches.

The pain relief usually lasts 6-8 hours. The exception: transdermal patches, which offer longer-lasting relief. That can last up to 96 hours, depending on the product.

When you vape or smoke CBD, you will feel the effects in less than five minutes. These two forms of CBD are ideal for anxiety and panic attacks because they provide calming effects so quickly. Inhalation is also beneficial for near-immediate pain relief.


After ingestion, it can take CBD anywhere from 30 minutes to a few hours before delivering any effects. If you dose on an empty stomach, cannabidiol tends to take effect more quickly. The amount of time that CBD oil stays in the system largely depends on the method of administration.

CBD inhaled by either smoking or vaping enters the lungs within seconds, resulting in a rapid onset of effects. This method of consumption also allows the substance to leave the system relatively quickly.

Dr. Flannery told us that a person’s body weight doesn’t really alter how long CBD will stay in the system. But metabolism does; those with fast metabolisms have smaller fat stores, so they have less storage capacity for the CBD that won’t be immediately processed by the liver. Those with slower metabolisms will retain CBD for a longer period of time.

CBD can affect the body and mind in several ways. Users will typically experience a calming effect and a general feeling of well-being.

While the type of CBD product you use factors into how long it will stay in your system, dosage plays more of a role. So does frequency of use.

Well, it depends on how much and how often you are dosing, the form of CBD, and perhaps most importantly, whether you’re using CBD isolate, broad spectrum CBD oil or full spectrum CBD oil. But it’s important to understand this: virtually no companies test for CBD. They’re only concerned about THC.


This chemical compound, also known as cannabidiol, is one of the many cannabinoids contained in the cannabis plant.

If you have medical marijuana certification, you can use any form of CBD or THC as long as it’s legal in your state. Bring your medical marijuana card with you when you are going in for your drug test. Your card is proof that you’re legally allowed to have those cannabinoids in your system.

Exercise and how we eat matter, too. Regular exercise is known to speed up our metabolism, and every time we eat, digest and store food, our metabolism gets a boost. This process is called the thermic effect of food.

When hemp-derived products became legal in America, the law provided that CBD oil and other CBD products could not contain more than 0.3% THC. The trace amounts of THC contained in the majority of CBD products cannot get you high, but might be problematic if you are tested. Learning the difference between CBD isolate, full-spectrum and broad-spectrum CBD will help you decide which is best suited for you.

The CBD compound is a fat-soluble molecule, and it can remain stored in our fat cells for up to 30 days. It’s important to remember that everyone is different, though, and various factors will contribute to how long CBD lasts in the body. Two of those factors are the type of CBD product, and how you consume it.

If that amount doesn’t help the condition you’re treating, slowly increase the dose in small increments until you find the amount that works best for you. Everyone reacts differently to similar dosages.

It’s understandable if you’re worried about how long CBD is detectable by a blood or urine test; many places of employment require random drug screenings for their employees, just as they do during the hiring process. Will CBD show up on one of these drug tests? What about the trace amounts of THC contained in hemp-derived CBD oil – will that show a positive result for marijuana?

We advise you to use CBD safely. If you think a drug test may be in your near future, err on the side of caution and stick with broad-spectrum or CBD isolate products. If you aren’t going to be tested, on the other hand, full-spectrum oil will provide the full entourage effect and be more effective.

For example, are you swallowing the oil or administering it sublingually? Sublingual use provides higher bioavailability and will take effect much faster, since the cannabidiol is moved right into the bloodstream. If you swallow CBD oil, some will be stored in fat cells until it’s metabolized.
