How long does CBD stay in your system?

how long does CBD stay in your system

Short Answer: Depending on different factors but in general 1-2 weeks. To avoid failing a drug test, use Broad-Spectrum CBD as it has zero THC.

Long explanation

CBD is a phytocannabinoid found in both cannabis plant and hemp plant and is gaining popularity in recent years due to its therapeutic potential. Even though hemp derived CBD products are legal in the US thanks to the 2018 Farm Bill, the fear of failing a drug test still are on the minds of some consumers.

CBD compounds are fat-soluble and can remain in our fat cells for up to 30 days. The method of consumption, type of CBD products, and your body’s metabolism are all factors contributing to how long CBD stays in the body. Keep reading to learn what those factors are so you know what to expect when you take CBD products.

What does CBD feel like?

The effects of CBD are experienced by everyone differently. But in general you can expect to experience a calming and general feeling of well-being. I call it the “after yoga” feeling. CBD works with the body’s endocannabinoid system in increasing the serum level of cannabinoid receptors. One of which is anandamide, it is known for reducing anxiety and promoting calmness. Another chemical compound, serotonin, is triggered by cannabinoids as well. Of course, you will not feel like this for 1-2 weeks after taking a single dose of CBD. A study published in 1991 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 700mg of CBD to 14 Huntington’s disease patients. One week after the dosing ceased, the CBD remaining in the blood was just 1.5 nanogram per milliliter and was “virtually undetectable” thereafter. The half-life of CBD is 2-5 days those who took a daily oral dose. Other delivery methods has varied half-lives. Most of the consumers taking CBD recreationally is taking anywhere from 12-75mg daily so you can expect it to leave your system within 2-5 days.

How long does CBD stay in your system? Let’s take a closer look

CBD compounds are fat-soluble and can remain in our body’s fat cells for up to 30 days. The method of consumption, type of CBD products, and your body’s metabolism are all factors contributing to how long CBD stays in the body. If you have a typical metabolic system, and you are taking an edible CBD such as oil or gummies, it is likely that it will be out of your system within a week or two. However, if you are concerned about passing a drug test, it is better to take a Broad-Spectrum CBD. This is because Full-Spectrum CBD, although thought to be better for you due to encourage effect, still has trace amounts of THC and that may trigger a false positive result. CBD, which doesn’t have any psychoactive effects, is left fully in a Broad-Spectrum product and has the same therapeutic benefits as Full-Spectrum CBD products.

To gauge how long CBD will stay in your system depending on a number of factors –

  • Metabolism: a person’s metabolism plays a prominent role in how fast CBD is metabolized and eventually excreted from the body
  • Frequency of use: it will take longer for it to exit the body for regular CBD users
  • Dosage: the mg of CBD you take will influence how long cannabinoids remain in the system. A large daily dose such as the one in the study will take longer because of the half-life of CBD is 2-5 days
  • Method of consumption: both the effects and length of presence in the body are contingent on how the cannabinoid is introduced into the body. This is due to bioavailability, which I talk about in length in this blog post.

Let’s discuss consumption method in detail

CBD Tincture and CBD Oil

CBD oil and tinctures are synonymous these days but they are not the same. CBD tincture is, by definition, alcohol based. It is made by steeping cannabis or hemp flowers in alcohol, then applying low heat to the mixture to extract the cannabinoids. Not many companies are using this method of extraction anymore as it is challenging to know how much of each cannabinoids are extracted. CBD oil is oil based and it is often made with CO2 hemp extract. Both are meant to be taken sublingually, or under the tongue. That allows the mucous membranes to absorb the maximum possible amount of CBD. The effects can be felt within 15 minutes and last 4-6 hours, and leaves the system within 1-7 days. If you are taking CBD oil, you will inevitably ingest a small portion of the oil. Take a look below for edibles…

CBD edibles and CBD capsules

Oral ingestion, or when you consume CBD by mouth, you can expect it to go through a lengthier trip through the body – your digestive system. Depending on your metabolism, it can take CBD anywhere from 30 minutes to a few hours before delivering any real effects. Typically, ingested CBD or edibles will be out of your system in 1-2 weeks.

CBD topicals

Topical applications come in a variety of forms, such as lotion, creams, salve, balm, body butters, patches and rollers. They are applied to the areas that are directly affected and it can take effect anywhere from 15 minutes to two hours. The pain relief usually lasts 6-8 hours and cannabinoids may remain in your body for up to 4 days.

CBD flowers and vaporizers

CBD inhaled directly into the lungs usually takes effects within seconds and leaves the body relatively quickly. We don’t recommend vape CBD though due to its harmful effects outweigh any health benefits. Depending on dosage, frequency of use and metabolism, you can expect the CBD to fully exit the body in 2-5 days.

Other factors that influence

Metabolism: every human body is different. There are several factors related to metabolism that will affect how long CBD oil stays in your system: whether you are taking CBD on an empty stomach, your body weight and metabolic rate, whether you have any medical conditions and your body mass. For the average person, CBD oil will leave your system within a week or two.

Frequency of use: if you have been using hemp products for a long period of time, it takes longer for it to leave your system completely

Dosage: similarly, if you have been taking large doses of CBD, it will take longer for it to exit

Will CBD show up on a drug test?

It’s understandable if you are worried about how long CBD is detectable by a blood or urine test. Many places of employment now require random drug screenings for their employees. Will CBD show up on one of these drug tests? What about the trace amount of THC in hemp-derived CBD oil – will that show marijuana use?

If you are taking Broad Spectrum CBD Oil, it is unlikely that you will fail a drug test. But make sure the company you are buying CBD from tests for CBD, you can see from this test result that our hemp extract contains ZERO THC.

In summary, hemp extract CBD can be a wonderful supplement to your daily regiment due to its therapeutic effects. If you think a drug test may be in your hear future, err on the side of caution and stick with broad-spectrum product or isolates. There are different ways to take hemp extract CBD and depending on your body, it will stay in your system for a week or two after you stop taking it. If this is your first time taking CBD, start with a smaller dosage than recommended and see how you feel. If that amount doesn’t help the condition you are treating, slowly increase the dose in small increments until you find the amount that works best for you. Everyone reacts differently to similar dosages.
