How Long Do CBDs Stay in Your System?

CBD (cannabidiol) is legalized in the US and many other countries around the world. In fact, it doesn’t cause intoxication even despite being sourced from the cannabis plant. The content of psychoactive substances (Tetrahydrocannabinol aka THC) is so low that CBD oil is less high-inducing than cough medicine. However, many people are reluctant to take cannabidiol because of fear of getting a positive drug test result.


Indeed, even such a tiny amount of Tetrahydrocannabinol can be found in urine and blood. On the bright side, CBD doesn’t linger in the body for too long after administration. But how long is this “not long”? Is it an hour, a day, or a week? Below, we are going to answer the question “how long do CBDs stay in your system?” and which factors affect removal time.


How Long Do CBDs Remain Detectable in Your System? 

Although CBD’s effects last for no more than 6 hours, its traces can be found in the body within 3-4 days. However, this isn’t always the case with different people. Actual times the compound needs to leave the system can vary dramatically. For example, a study carried out in 2005 shows that small servings of CBD and THC cannot be detected after 9 hours in the body. On the other hand, if you take CBD on a daily basis, it tends to accumulate in tissues. Therefore, the elimination period lasts longer. Various research shows that CBD can stay in the system for up to 2 weeks.


Factors Affecting How Long CBD Stays in Your System

As we’ve already mentioned, the frequency of taking CBD medication has a significant impact on the trace detection period. However, this is just one of many factors, others of which include:


  • Metabolism. People with good metabolism tend to reduce drug concentration in their bodies at a faster pace.
  • Body weight. Cannabidiol accumulates in adipose tissue. If you have a significant amount of body fat, it will release small doses of cannabidiol over a long period of time, especially if your weight fluctuates. At the same time, you shouldn’t worry that your fat cells may stash some CBD if you took a one-off dose.
  • Food. Certain types of food increase the bioavailability of CBD oil. This ends up with higher concentrations in the blood than usual. If you take CBD on an empty stomach, it is digested and excreted from the body much faster.
  • Dose of CBD. The more CBD you take, the longer it takes to remove it. Accordingly, its traces can be determined over a longer period of time.
  • Way of administration. The chosen administration method affects the rate of elimination as well. Vaping, for example, offers an expedited onset of action, and CBD leaves the body just as fast. Tinctures taken sublingually start acting and get flushed much slower. CBD edibles and oral preparations travel through our bodies even slower. Topicals, although being applied locally, are the champions in lingering in the body. Cannabidiol molecules seem to get stuck in muscles and adipose tissue, and it takes a long time for them to find a way out.



In conclusion, it should be pointed out that many drug tests are designed to detect THC specifically instead of CBD. It’s likely that taking CBD oil deprived of THC won’t fail your test. Therefore, you don’t have to worry about excretion times.
