Given the relative novelty of CBD as a product, it’s perfectly understandable that many characteristics of CBD are still widely disputed among the scientific community. Fortunately, research into the compound is often more intensive than that of comparable substances, resulting in some of the mysteries surrounding the CBD itself being properly explained. Among those is the question many regular CBD users were always particularly interested in – how long does CBD stay in your system?

This issue is perhaps one of the most interesting to consider, mainly due to the fact that there is no simple answer to that question. While some properties of the CBD can be universally agreed on, such as the half-life of CBD being known to be between 18 to 32 hours, there is no simple answer to how long does CBD stay in your system. Read on as we explain in detail just why it is the case here.

The Time It Takes Your Body To Get Rid of CBD Is Highly Variable

Truth to be told, there is no single, specific timeframe within which your body flushes itself of CBD. In reality, there are numerous factors influencing the length substances like CBD stay in your body, chief among them:

The Dosage Used

The dosage of CBD you’ve used is one of the most important factors when it comes to how long CBD stays in your system. After all, the higher the dose, the longer it will take for your body to get rid of it. Moreover, the frequency with which you’ve used your CBD products affects the CBD concentration just as much as the singular amount. After all, one big dose taken 12 hours earlier is going to leave less CBD in your system than 6 small doses over the span of a few hours, simply because your body has had more time to process the entirety of it.

The Amount of Food You’ve Consumed Prior To Taking CBD

In addition to the dosage, the amount of food you’ve consumed in the hours prior to taking CBD products also matters. This is simply because any sort of nutrition consumed is going to occupy your digestive system, slowing down your metabolism considerably and therefore the processing of CBD. The more you eat, the longer it’ll take to take care of CBD in your system. As such, it may be best to consume CBD on empty stomach, so that it can focus primarily on the substance itself.

The Method of Administering CBD

One of the more telling factors when it comes to metabolizing CBD is the way you’ve applied it. The most popular methods include vaping CBD, ingesting it (e.g. CBD gummies), and applying it topically (using, for example, CBD salves). It stands to reason that the method you’ve chosen will have a very profound impact on how long CBD stays in your system.

The first, vaping, is arguably the quickest of all three. This is because it allows for direct intake of CBD into the bloodstream through the pulmonary system, bypassing the digestive tract completely. This means that you will be able to feel its effects much faster than taking it by mouth or via a skin product. Because of its quick onset time, it’s also quicker to be metabolized by your body. A CBD cream, on the other hand, will take longer to affect your system and consequently longer to get rid of.

Your Metabolism

This one is very much unlike the others in that you have less control over the rate at which your body metabolizes the substances you’ve ingested. And the rate varies a lot, meaning that some will naturally take much longer to become CBD-free than others – just like there are those who can continuously eat a horse and stay fit while the rest has to keep themselves in shape the hard way.

Why Does It All Matter?

Now we’ve reached the proverbial elephant in the room. After all, commodities like CBD oil are perfectly legal in a large number of places so why does it matter how long CBD stays in your body? The truth is that CBD might be non-intoxicating, but some of the other substances commonly found alongside it in products are anything but.

Take THC, for example. Tetrahydrocannabinol is a major psychoactive component of the marijuana plant, a drug that’s still considered illegal around much of the world. And the governments aren’t the only ones that enforce this state of affairs.

Workplaces Often Institute THC Drug Tests

Such a drug test is designed to pick up even the small amounts of the substance in your system. One might think that it doesn’t concern cannabidiol, but there are in fact CBD products such as full-spectrum CBD oil that contain some THC in them.

Depending on your luck, some of the more in-depth tests can pick up these trace amounts found in some CBD products and that may lead to some serious trouble. While the chances of getting a positive result during the drug screening aren’t overly high, it nevertheless remains a viable issue.

Drug Testing Is Highly Varied in Form

The length of time THC is detectable in the system also depends on the carrier that’s tested. While blood tests are considered less-risky due to your veins being THC-free after a few hours, the urine tests can detect THC leftovers for much longer – sometimes even a month after consumption. Saliva tests lie solely in the middle, having the capacity to pick up the tested substance after a day or so, eating those tasty full-spectrum CBD cookies an evening before work might not be the best idea. Hair tests are the most extreme, being able to pick up tetrahydrocannabinol after even 90 days, although these often give a false positive drug test result.

The situations involved are easy to imagine too, e.g. you took potent CBD products to relax during the Sunday afternoon and the next day the workplace drug test detects the trace amounts of THC in your system. The likelihood of such a scenario is quite high, given that some countries like the USA still don’t regulate CBD products on a national level, merely setting up a THC content limit.

THC-Free CBD Products Are the Safest Option Here

Given such a situation, it might be best to choose products such as CBD oil without the presence of THC. Although lacking the psychoactive component mentioned above, the truth is that the CBD compound itself should be more than sufficient to provide the type of relief you expect from it, diminishing the risk of scoring positively on a THC drug test to practically zero. After all, most drug tests actively target only the latter substance.


So there you have it. The time it takes your body to flush itself of a CBD product is highly dependable on a large variety of factors, such as the dosage, the food consumed before it, the consumption method, and your metabolic rate. It is important to know because some of the CBD product variants may contain minuscule amounts of THC that might be detected via drug tests – something you don’t want to experience in your workplace.

Now that you understand the specifics concerning the CBD itself and its metabolization, you can now safely avoid trouble with the drug tests and consequently problems at your workplace. Good luck!
