How Long Does CBD Stay in Your System? The Complete Guide

If you’ve never used CBD before — or even if you’re just starting — you probably have a million questions on your mind. One of the most common questions is, how long does CBD stay in your system? Some people fear it will show up on a drug test, while others want to know how long the effects of the CBD lasts.

If you’re wondering how long CBD lasts, keep reading.

How Long Does CBD Stay In Your System?

There are a few things to consider before diving into the answer to your question.

First, it’s worth noting that we need more research to say anything definitive. While we have some research regarding how long CBD lasts, we don’t have a lot. So, results may be very different from person to person.

There are also a few different factors that affect how long CBD stays in the system. These include:

  • Dosage: The more CBD you take, the longer it may stay in your system.
  • Frequency/Tolerance: The more frequently you take CBD, the more of a tolerance you build. This may affect the staying time.
  • Intake Method: There are a lot of ways to take CBD. Vaping CBD, for example, may last shorter or longer than oil, edibles, etc. in certain users.
  • Metabolism: If you have a fast metabolism, CBD may flush out of your system faster than those with a slow metabolism.
  • Food: Whether or not you’ve eaten recently has an effect on how long the CBD stays in your system.

With that out of the way, here’s what we know about how long CBD lasts.

How Long Does CBD Last?

The studies we have regarding how long CBD lasts gives us a guideline to follow.

One study shows that CBD oil lasts between two and five days when taken regularly in oil form. Smoking CBD-dominant strains showed a shorter time of 31 hours. This is a very broad range of times, but gives CBD users a frame they can work within.

A much older study from 1991 examined the blood of CBD users after high doses. Test subjects took CBD for six weeks, and then had their blood examined after a week of non-use. The study found 1.5 nanograms remaining in the blood, a nearly undetectable amount.

So, while we don’t have a solid answer, we can safely say CBD stays in the body for at least five days if not longer. That doesn’t mean the effects last that long, it just means the substance is still in the bloodstream.

Can I Fail a Drug Test If CBD Is Found in My Blood?

You’ll be happy to hear that the cases where CBD causes you to in you faili a drug test are extremely rare.

Most drug tests don’t even test for CBD, as it’s not psychoactive. Although it’s present in marijuana, it’s not the compound that gets people high. THC is responsible for getting a person high, so it’s the presence of THC you need to worry about.

It’s important to remember, though, that certain CBD products do contain trace amounts of THC. A CBD product can have up to 0.3% THC and still go on the market. Although this is a trace amount, it is possible that THC will show up on a drug test if you take CBD products that contain it.

If THC is found on a drug test, it may result in a failure depending on the state you live in. Assuming you don’t regularly ingest cannabis, THC should leave your system in about 3 days. However, it may last as long as 30 days in a regular smoker.

How to Avoid THC in CBD Products

If you’re worried about THC in your CBD products, it’s important to seek out CBD products without THC. There are two types of CBD that don’t contain THC: broad-spectrum CBD, and CBD isolate.

CBD isolate is pure CBD, with all cannabinoids (including THC) removed. This is the purest form of CBD you can get, and is often used by athletes and those who undergo regular drug tests. You can get CBD isolate in oil form, as cbd oil cream for pain, and in any other form you can get other CBD products.

Broad-spectrum CBD products include all the naturally occurring cannabinoids except for THC. The THC is removed in the manufacturing process. This gives the user the most natural way to take CBD without the worry of THC, as the other cannabinoids enhance the effects of the product.

The other cannabinoids in broad-spectrum products won’t show up in a drug test. Drug tests typically only look for THC and other psychoactive drugs. If it can’t get you high, it’s not worth testing for.

How Long Does CBD Effects Last?

Just because CBD lasts in the body for a week or longer doesn’t mean the effects do.

It’s generally believed that the effects of CBD last between two and eight hours. The compounds remain in the body, but don’t continue to benefit the user after that. Again, this depends on multiple factors, so eight hours is a conservative estimate.

Taking CBD: Don’t Worry

So, how long does CBD stay in your system? The answer is we don’t know for sure, but you can expect it to last up to a week or longer.

Thankfully, you will almost never fail a drug test as long as you’re using a THC-free CBD product. Always check the label before buying, or ask for help finding THC-free products. That way, you can worry much less about how long CBD lasts in your system.
