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.
A 2018 review of existing CBD studies found that the estimated half-life of CBD was two to five days for those who took a daily oral dose. Other delivery methods delivered varied half-lives.
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.
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.

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.
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.
What’s best? If you’re taking CBD for pain management or anxiety relief, you can probably get away with smoking it. However, if you’re concerned about drug tests or are taking it orally to treat any other conditions (for example, sleep disorders), it’s best to use oil form products that will leave no traces in your system after 30 days.
Different formats of CBD can also make it easier for the product to be passed out of your system. Tinctures are one of the best-absorbed formats of CBD.
What Factors Effect How Long CBD Stays In Your System?
The longer you’ve waited to take CBD, the harder it will be to detect in your system.
Many people are wondering how long does CBD stays in your system. As we will see later on in the article, a few factors determine how long cannabidiol (CBD) stays in your system. We’ll delve into what those factors are and take a look at some scientific evidence as well as anecdotal evidence from people who use CBD for pain management or anxiety relief. This blog post aims to provide an answer to the question: How Long Does CBD Stay In Your System?
How Long Is CBD Detectable In Your Body?
As with most substances, including any medication or illicit drugs, the answer to the question of how long does CBD stays in your system depends on several factors. These factors include frequency of use, dosage, consumption methods, metabolism, body weight, dosage, what format CBD you use (oils vs. smoking vs. eating), and more.
