So you’re wondering how fast you can flush cannabidiol out of your system? Or, more likely you want to get the trace THC from full-spectrum CBD out of your body. How long CBD stays in your system depends on a number of important factors. Generally, it’s safe to say 2 to 5 days, but for some users, CBD can remain in their bodies for several weeks.

In the rest of this post, we’ll cover

  • What those determining factors are
  • CBD and drug tests
  • And, how to properly flush CBD from your system 

How Long Does CBD Stay In Your System?

Below we’re going to talk about the four main factors that will determine how soon you can flush CBD from your system.

Last Time You Took CBD

The biggest, but often overlooked factor in how long CBD stays in your system is the last time you took CBD. All other factors aside, if you just took CBD, expect CBD to be in your system.

If you took a single large dose (150mg +) of CBD more than a month ago, then there’s no chance that it would still be present in your system.  

How Much CBD You Take

Cannabinoids and CBD in particular are just like other supplements in this regard. The higher your dosage of CBD, the longer it will stay in your system at any measurable level. 

How Often You Take CBD

The frequency of your CBD use will also play a big part in determining if CBD is still present in your system. 

CBD builds up in your body over time with prolonged regular use and takes longer to completely clear from your system. (This is also the reason it sometimes takes a few weeks of regular use to realize the benefits of CBD.) 

Your Body

Everyone is different. Body fat percentage, water content, and metabolism to name a few genetic factors can affect how long CBD stays in your system. Because CBD and other cannabinoids are fat soluble, they tend to linger in bodies carrying higher percentages of body fat. 

Do You Take Your CBD With Food?

This is more specific to edible CBD. If you take CBD edibles or CBD oil on an empty stomach, you will metabolize and clear it from your system faster. On the other hand, if you take your CBD with food, the effects of the CBD will last longer, but you will metabolize the CBD more slowly. 

Does CBD Show Up On A Drug Test?

The short answer is: Yes, using CBD products can show up on a drug test. 

The moderately longer answer is that drug tests aren’t testing for Cannabidiol (CBD). They’re testing for any trace amounts of THC that may be present in your CBD product.

How Do You Flush Your System Of CBD? 

If you absolutely must flush your system of CBD, there are a few safe options you can choose from… and some not-so-safe options. 

It’s important to note that CBD leaves your body just like everything else— via sweat, urine, and defecation. With that in mind…

Drink More Water

Drinking more water will make you urinate more frequently and will help flush the CBD from your body. It’s important to not overdo this one as too much water can flush vital nutrients from your system and more to the point, lead to a failed drug test because of artificially low creatinine levels. 

Eat More Fiber, Fewer Fats

CBD is fat-soluble and will hang around your body longer if there is more fat to latch on to. In order to flush the CBD from your system faster, eat more fruits, vegetables, and beans. These, in addition to drinking more water, will help make you more regular. 


Kick it up a notch at the gym. Breaking a good sweat is a great way to flush CBD from your system. It will also prompt you to drink more water.

Don’t Take Detox Pills

With the first three flushing methods above, you have control. Detox pills may promise the same results faster, but who knows what fillers are in them. 

Be Patient

Above all other flushing methods, the best method is patience. Your body is great at detoxing and will clear out all CBD if you cease to take CBD and give your body time. 

Takeaways: How Long Does CBD Stay In Your System?

There are plenty of factors that affect how long CBD stays in your system and how long it takes CBD to leave your system. If you’re concerned about having CBD in your system, the best thing you can do right now is stop using CBD and give your body ample time to flush the CBD naturally. 

If your concern is failing a drug test, there are THC-free CBD products that will not make you test positive on traditional drug tests. One such product is Sunset Lake CBD’s Sour Gummy Bears.
