How Long Does CBD Oil Stay in Your System?

December 7, 2019

As CBD oil and hemp oil receive more positive press in the media and all over the Internet, more and more people are queuing up to experience the positive health benefits for themselves. With so many questions being asked with regards to how it works and what can it help with, one of the most poignant questions on everyone?s mind these days is how long CBD oil stays in your system.

The truth is, whether you ingest it through a vape pen, a CBD tincture, or through tasty CBD gummies, it can be rather difficult to pinpoint an exact answer due to the fact that cannabis has been classified as an illegal substance for such a long time and? research on the efficacy of cannabis derivatives such as CBD oil and hemp is still lacking and even trace amounts may be deemed illegal. With regards to how long you can expect CBD oil to linger in your system, as a general rule of thumb, the effects start wearing off after around four hours, but the compound can still remain in your system for a week afterward, depending on the CBD dosage and whether or not it is pure CBD.

Regardless of whether your curiosity stems from potentially having to pass a drug test at work, or simply because you want to know how many times a day you will need to take a dose of CBD, the following information will help you to understand how long CBD oil will take to pass through your system entirely.?

Factors That Determine How Long CBD Stays in Your System

As humans, we are all unique individuals and our body eliminates toxins and chemicals at different rates. Some people can go out and drink alcohol all night and feel completely fine and sober the next day?that?s because their body has metabolized the toxins faster. The same is true of CBD oil and other supplements. There are so many factors that contribute to how long it will stay in your system and your metabolic rate will be one of the primary determining variables. If you are of a healthy weight, your digestive system is functioning properly, and you drink a lot of water every day, you may find that you can flush your system out entirely within a few days. For others who are heavier, taller, and have a slower metabolism, it might take longer.

The method of consumption you choose to take CBD will also influence how long it will be detectable in your bloodstream. Vaping CBD oil is one of the fastest ways of delivering the benefits to your system and it will wear off quicker than if you eat CBD gummies that have to pass through your digestive system to completely eliminate all traces of it.

How Long Do the Effects of CBD Oil Last?

Knowing how long the effects of CBD oil will last in your body is important when it comes to knowing when you need to take another dose. If you are among those who have taken CBD oil for the first time and then eagerly awaited experiencing an instant effect, but you found that it didn?t work as well or as quickly as you had hoped, then rest assured, you just need to give it time. If you have purchased a good quality full spectrum oil, then there is no reason that it shouldn?t work for you. Many CBD users start to notice a positive improvement in their symptoms approximately an hour after taking a dose and they also report the effects to start wearing off around 4?5 hours later. The more you take CBD oil and the higher potency you use, the longer the effects will last. So, be sure to take all of that into account before deciding how frequently you should be taking your oil.

What Does Existing Research Say?

With regards to existing studies that focus on the clearance time of CBD, researchers have discovered that it can take up to four days for all traces of CBD to completely leave your body. A recent study highlighted that the half-life of CBD oil is between two and five days, dependent on your metabolic rate, weight, height, and age. People who take higher dosages of CBD oil can also expect it to remain in their system for longer.

The coming years will see more scientific research emerging that will give us more clarity on CBD when used for therapeutic and medicinal purposes, allowing us to draw more conclusive opinions about the pharmacokinetics of mother nature?s finest elixir.

Can My Physician Provide Me with Proof That I Need to Take CBD oil?

Can My Physician Provide Me With Proof That I Need To Take CBD Oil

Unfortunately, due to the fact that CBD oil is still undergoing FDA approval, it is unlikely that a physician will be able to confirm that CBD oil is essential to your well-being, as currently it is classified as a natural supplement. If your employer is open to hearing you out, then you could request a letter from your physician that confirms the ailment you wish to take CBD oil for and also that it will not impair your judgment. This will be entirely down to your doctor?s discretion.

Does That Mean I Only Need to Take CBD Oil Every Few Days?

No, you will need to take it more frequently to experience the full benefits it can have on your health. The effects of CBD will start to wear off after a few hours, so if you are using CBD for pain relief, anxiety, or other health reasons you will need to take another dose when you feel it has worn off. It is also worth noting that CBD should be incorporated into your daily routine for best results, not just taken in order to provide a quick fix for a sudden onset of ill health. The reason the oil is so potent at providing relief for a range of ailments is because it triggers receptors in your brain that send out healing to parts of the body that need it the most. With time, many existing CBD users report that they have noticed their symptoms disappearing altogether.

Will CBD Oil Affect a Drug Test?

The majority of employers require you to commit to drug testing for a number of different reasons, but mainly to ensure that the workplace continues to be a safe and productive place. In some circumstances, a drug test is required by law to demonstrate that you are not impaired by the use of a prohibited drug and this is what most employers worry most about. The good news is, CBD oil produces zero psychoactive effects as the trace of THC (the compound in a cannabis plant responsible for the high you feel) is so minimal and, in some situations, non-existent. As CBD does not impair your judgment or negatively alter your state of mind, most drug tests are not designed to pick up on it.

That said, some employers will use a type of drug test that screens for absolutely everything, in which case, if the CBD oil you use contains a faint trace of THC it could show up as positive. The best thing to do if you are unsure of where you stand with regards to using CBD oil is to speak to your employer and explain your reasons for wanting to use it and ask if it is going to be an issue. Many smaller corporations are willing to make allowances, particularly if they value your skills and understand that you would like to use it for health reasons.

If CBD oil has not yet been legalized in your state, then you could expect it to be a deal breaker if you test positive for it on a drug test.

How Will CBD Affect You in the Long Run?

While it is true that some people have experienced dramatic results within 24 hours of taking their first dose of CBD oil, for many others it takes a few days or even weeks until they notice a significant difference. CBD builds up in your system over time and it will continue to work as a therapeutic remedy, healing different areas of your body. If you want to experience a dramatic improvement in your health and you are in it for the long run, then you have to give the CBD oil time to work. Remember, the more CBD you take, the longer it will remain in your system and continue working its magic.


CBD oil has won itself a stellar reputation, thanks to its incredible health benefits that include giving you relief from:

  • Depression
  • Pain
  • Arthritis
  • Epilepsy
  • PTSD
  • Anxiety
  • Insomnia

And the list goes on!

One of the primary reasons why it is so loved as a natural remedy is that it doesn?t produce psychoactive effects like those caused by marijuana, so you can go about your daily business as usual. Before purchasing any kind of CBD oil, always make sure that you are buying from a reputable brand who can back up their claims with evidence like lab reports. This is especially important if you are worried about failing a drug test and you want to make sure that the oil you buy is completely free of any traces of THC. If you are fortunate enough to live in a state where marijuana has been legalized, then you should check with your employer as to whether or not you can take a high-quality tincture containing the legal trace amount of THC. As you have learned from this article, everyone?s body processes and absorbs CBD oil in a unique way, so be sure to bear this in mind when you are planning how often to take your oil. If you are required to perform a drug test that has been designed to pick up on CBD, then take your last dose 10 days before your scheduled test to be on the safe side.
