How Long Does CBD Stay in Your System?

Use this guide to learn about CBD, its effects, how long it stays in the body, and test methods.

A Look at CBD

CBD is the acronym for cannabidiol, a chemical found in the cannabis plant. Cannabidiol can be taken internally in multiple ways, including inhaling cannabis smoke or vapor, consuming by mouth, and as an aerosol spray into the cheek. While current scientific evidence suggests that heavy cannabis use may increase the risk of dependence in some people, CBD by itself does not appear to be addictive.1

CBD is not screened in drug tests because it does not cause intoxicating effects, nor is it an illegal controlled substance. Therefore, a full spectrum CBD drug test does not exist. Nevertheless, people who use CBD may still fail a drug test. In addition, products that contain CBD may be contaminated with THC or have improper labeling.2

Understanding THC and CBD

Since both THC and CBD are present in recreational marijuana, several online searches are often related to CBD to try to mislead drug tests. These include: 

Please note that any searches like these, particularly any related to “How long does CBD stay in my system?” for the deception of CBD drug tests, are not only dangerous but can also be illegal. Drug tests are legal requirements in many situations, and interfering with them can cause serious harm. 

What Is Cannabidiol (CBD)?

Cannabidiol (CBD) is a chemical in the cannabis sativa plant, also known as cannabis or hemp. One specific form of CBD is approved as a drug in the U.S. for seizure.

Over eighty chemicals, known as cannabinoids, have been found in the cannabis sativa plant; however, Delta-9-tetrahydrocannabinol (THC) is the most well-known ingredient in cannabis. CBD is obtained from hemp, a form of the cannabis sativa plant that only contains small amounts of THC. CBD seems to affect some chemicals in the brain, but these are different from the effects of THC.

A prescription form of CBD is used for seizure disorder (epilepsy), anxiety, pain, muscle disorder (dystonia), Parkinson’s disease, Crohn’s disease, and many other conditions. Still, there is no good scientific evidence to support these uses.

Laws passed in 2018 made it legal to sell hemp and hemp products in the U.S. Though, that doesn’t mean that all CBD products made from hemp are legal. Since CBD is an approved prescription drug, it can’t be legally included in foods or dietary supplements.

CBD can only be included in “cosmetic” products, but there are still CBD products on the market labeled as dietary supplements. The amount of CBD in these products is not always the same as stated on the label.3

Epilepsy Treatment

After years of research into the safety and effectiveness of CBD oil for treating epilepsy, the FDA Trusted Source approved the use of Epidiolex in 2018, a purified form of CBD. It was approved for treating the following in people aged three years and over:

There is ongoing research into the effectiveness of CBD to treat:4

How Our Bodies Store CBD

CBD is fat-soluble, meaning it’s stored in fat cells and not water cells. As a result, one’s body mass index (BMI) influences how quickly it is metabolized—the higher the body mass and weight, the longer it takes to leave the system. 

Factors That Influence How Long CBD Stays in Your System

How long does CBD stay in my system? and how long do CBD gummies stay in my system? are not straightforward questions. The time it takes for CBD to leave a person’s system depends on a few different factors, including:

The Dose of CBD

Usually, CBD takes about one day to be flushed out of the system after taking a single dose. Nonetheless, the higher the dose, the more time the body will need to get rid of it.

How Often You Consume CBD

The frequency of use also determines how long CBD will stay in the system. CBD accumulates in the body over time when used regularly. Most experts suggest taking CBD for at least two weeks to see how it affects a person’s health and whether or not they are reaping the benefits. For occasional use, the time CBD leaves the system is shorter. 

Your Unique Body Chemistry

Everybody is different. People have different diets, lifestyle habits, metabolisms—all of which can affect how they metabolize CBD. In addition, fat content, body mass index, and age will also influence the time CBD remains in the body.

Consumption Method

CBD is found in many different formats. The method of administration affects everything from the onset and duration of effects to the time required for the CBD to leave the system. CBD is available as the following products:

CBD can stay in the body for as short as a few hours or as long as a couple of months, depending on the factors above.

Types of Drug Tests for CBD and THC

The various ways CBD and THC are detected and tested include:

Urine Drug Test

CBD remains in urine for three to five days. So, as long as someone doesn’t use CBD for at least five days leading up to a test, they should be fine. THC metabolites, however, linger in urine for up to fifteen days. 

Hair Drug Test

The THC metabolites from CBD products stay in the system for up to ninety days. The compounds that eventually pass through the bloodstream become part of one’s hair. It takes at least five days before CBD and THC are detectable in a person’s follicles.

Saliva Drug Test

Research on how long CBD stays in the saliva isn’t as robust as other areas. If CBD oil is consumed, the dose is expected to last in oral fluids for up to three days. The duration may be longer depending on the method and frequency of use.

Blood Drug Test

Blood tests are far less prevalent than urine or saliva-based ones. One reason is that they’re not as reliable for detecting CBD or THC. In addition, THC is only detectable in the bloodstream for up to five hours, while CBD stays in the blood for up to a week.
