People are worried as to how long does CBD stays in your urine. While this substance is not controlled by the government or employers, most people want to stay safe during screening.

A lot of people want to know how long does CBD stay in your urine.

While this substance is legal in the USA, there are some restrictions to its use. For example, some of the states have specific laws regarding CBD edibles. Oftentimes, these regulations might be confusing, which is why a lot of the CBD users don’t know whether they can have a positive result during screening.

Luckily, CBD drug tests are very rare. Most organizations and companies perform these tests to find THC metabolite, as well as some other, move volatile chemicals in the bloodstream. While CBD consumption is not that big of a deal, trace amounts of THC content can indicate that a person has used marijuana.

Keep in mind that urine tests, hair test, or saliva test cannot determine if this was recreational or medical marijuana. In other words, you will be liable either way.

In this article, we will see how long does CBD stay in your urine and whether you should be worried.

Main factors affecting CBD levels

Whether we're talking about hemp derived CBD or cannabis plant extract, the same basic rules apply. There are numerous things that determine how long a substance will remain in your body, such as:

  • Speed of metabolism
  • Substance tolerance
  • Consumption method
  • The overall quantity of a CBD product
  • The concentration of a product
  • Use of other drugs that might interact with CBD
  • Frequency of use
  • Age and weight

Keep in mind that some of the CBD products will have no impact on the urine test. For example, CBD topicals won’t even penetrate your bloodstream. This is why delta 9 THC cannot cause psychoactive effect when put on the skin.

These factors are important not only for determining how long a substance will stay in your body but also for finding the right dosage. Speed of metabolism and weight are also major considerations when trying to determine the quantity of hemp derived CBD.

How will a higher quantity of CBD affect my body?

Our bodies need some time to process CBD. Depending on your method of use, you can feel the first effects within 10 minutes or after an hour. 

While you might think that cannabidiol will stay in your body for as long as you feel benefits, this isn’t true. The benefits will persist just for a little bit, but CBD can be detected for much longer.

As you continue therapy, these trace amounts will pile up. While our bodies are able to regularly flush out cannabidiol, you might feel more saturated as you continue using. This problem is especially troublesome because prolonged use also increases tolerance prompting you to increase the dosage.

Now, not only will you have to use increased quantities to achieve the same CBD effect, but you are also more likely to test positive. This goes for both CBD and THC.

High quantities of CBD in the body can cause its own issues. For example, you are more likely to experience side effects the next time you use one of the products. These side effects might also become more severe. This, and the fact it becomes harder to feel benefits, is why doctors suggest that you make breaks after a while.

What do studies say?

There aren't many studies that focus on CBD and urine tests. Like with most other medical hemp related things, it is somewhat of an unexplored topic.

One of the few reference points is a study from 2016. There were 15 participants, and they were given a variety of CBD products. After consuming CBD oil, inhaled CBD, and other substances, they were put to the test after 2 hours.

As you can presume, most of them tested positive for CBD molecules and other cannabinoid (14 out of 15 people). One of the participants was screened once again after 24 hours. This subsequent test has shown no signs of cannabidiol in the body.

Unfortunately, this study doesn’t say much about CBD or the tests. It is to be expected that a person would test positive if you perform a check up after 2 hours. Perhaps the only interesting piece of evidence is that the one person who performed the test after 24 hours wasn't positive. In other words, the participant managed to flush out the substance relatively quickly.

Perhaps the biggest problem with this particular type of research is that most scientists are unwilling to go through it. Simply put, most companies and institutions are not interested in CBD screening but instead, THC level. These types of tests are too rare to warrant excessive research.

Cannabidiol in the body

Industrial hemp is generally viewed as a safe plant. Even if you use it frequently, it should not cause major side effects. However, the method of consumption, dose, and user over time, can all play a part in metabolizing the chemical. For example, if this is your first time using one of these products, you are less likely to test positive, compared to a person who used them for a while.

Based on what we know, you can test positive during a urine test for 24 hours after you've used it. But, this only pertains to individuals who took it once, and the dose was not excessive. On the other hand, someone who vapes CBD flower or takes CBD oil regularly will need much more time to eliminate the chemical. In these cases, it might take up to a week for a person to remove traces of cannabidiol from the system.

When calculating the expected time of metabolizing, you need to consider the dosage. Smaller quantities are really easy to flush out. According to one small study, it takes a person 6 hours to completely eliminate the product in a smaller dose.

You also need to consider your weight and age. So, if a heavier individual takes 20 milligrams, this person will be able to eliminate the chemical much faster. The speed of metabolism, which is connected to age, will also help in this case. Athletes, for example, are able to get better results compared to other users.

CBD’s bioavailability and connection to urine tests

Bioavailability is something that is often tossed around among CBD users.

Basically, this refers to how much of the substance we can utilize. Some of the CBD products are notorious for their low availability, which almost makes them economically unfeasible. 

 When you use cannabidiol, at one point, it will pass through your stomach, skin, or lungs (depending on the application). So, if you use edibles that go through the stomach, you will only get 4 to 10% of the substance. The majority of it will be lost somewhere along the way due to digestion and other bodily processes.

Experts believe that bioavailability might have something to do with how long CBD stays in the body. For example, edibles have low bioavailability, long duration, and we think that they stay in the body the longest. On the other hand, CBD oil will remain for a shorter period of time, and it might be flushed quicker.

How do products affect urine tests?

 There are a lot of different products that CBD user take.

Firstly, we differentiate items based on the underlying CBD oil. You have CBD isolate (or pure CBD oil), full spectrum CBD oil, and broad spectrum CBD oil.

  • CBD isolate only has one substance - CBD. That way, consumers can focus on the potential benefits of this chemical while also omitting everything else.
  • Full spectrum CBD has all the same chemicals as the hemp plant. Nothing is removed. Among others, it also has some THC.
  • Broad spectrum oil is like full spectrum, but it doesn't have THC. It is a version of hemp oil extract that is great for people who want to avoid this psychoactive substance.

As you can presume, CBD isolate has the highest concentration of cannabidiol. While other products have other chemicals, this one focuses on just this one. Based on that, scientists believe that the isolate is harder to flush out from the body. That is, compared to a substance that has the same volume. 

We also need to consider concentration. For example, two isolates can have completely different concentrations of cannabidiol because they relied on different strains during the production of CBD oil. Also, other ingredients within a bottle can dilute the impact.

Should I be worried about these tests?

CBD is now legalized in most countries of the western world. Even if you test positive on the chemical compound, there probably won't be any repercussions. Keep in mind that this is a safe substance that is mainly used for its wellness properties.

However, we suggest caution if you're using a product that has THC. As long as the product is derived from hemp, it will have small quantities of psychoactive substance. But, prolonged use makes it harder to flush out. Also, almost every screening focuses on this substance, unlike CBD.
