How Long Does CBD Oil Last In Your System: The Truth!

So, maybe you’re going after that new position at work, or you’re doing further research to find out more about CBD Oil.

Regardless of the reason for your search, you just want to know how long does CBD last in your system and how this could affect you.

You can typically expect CBD to stay in your system anywhere from 2-5 days if you’re not a regular user however, if you’re a daily CBD user, you can have traces of THC in your system for a few weeks.

There are a number of different factors that play a role in not only how long CBD lasts in your system but how soon and how long you start feeling the effects and how long they last can be different.

In this guide we’ll be getting into not only what factors can determine how CBD affects you but what types of CBD is best depending on your body and lifestyle choices.

5 Factors That Impact How Long CBD Can Stay In Your System


While weight may not have been the first variable that came to mind, it definitely has a heavy influence on how long CBD lingers around in your system.

This is due to CBD being a fat-soluble compound and because of that it is stored in the body’s fat cells.

If you have a higher BMI (Body Mass Index), its possible that you’ll hold on to excess CBD longer than someone with a lower BMI who can quickly burn fat.

So in short, the higher your metabolic rate or the lower your BMI, the faster your body will process the CBD, reducing the duration of your side-effects.


Are you taking CBD on an empty or full stomach?

Depending on your answer, this will determine not only how quickly you’ll feel the effects of CBD but actually how long you’ll feel it for.

If you consume CBD on an empty stomach, you can expect to start to feel it working much quicker, this is because it gets metabolized faster than it would if you were to take it on a full stomach.

Method of Consumption

You may already have a preference on how you like to consume CBD but the way you’re choosing to, can dictate how long its taking for it to run through your system.

Topical Cream

Topical CBD can come in many different forms such as: salves, creams and balms, and while highly effective in treating issues like joint pain, this choice of application takes the longest to start feeling effects compared to the other consumption options.

It first has to be applied directly to the skin, its then absorbed through the skin’s surface and interacts directly with cannabinoid receptors to effectively alleviate pain.

CBD creams do not get you high and typically contain low- to no levels of THC, the chances of it showing up in your system is slim to none.


When taking capsules, they have to travel through your digestive system before they are absorbed which can take some time, depending on how fast your body metabolizes ingestible forms of CBD.

It can take anywhere from 4-6 hours to start feeling the effects but will take longer to leave your system.


Since inhalation involves the products being absorbed by the lungs, effects are felt almost immediately and can last from an hour to six hours. Everyone is different, so where you may feel the effects longer, someone else may not feel them as long.


This is another way of CBD passing through the digestive system, meaning it’ll take a little longer to start feeling any effects. Typically, you can expect to feel some changes around the 60-minute mark and being to last up to 6 hours.

Oral consumption has been known as a less effective method due to the fact that only about 5% of the CBD ends up in your bloodstream.


These work a lot like capsules, due to the fact that they are ingested and passed to your bloodstream. With tinctures you hold the oil under your tounge anywhere from 60-90 seconds, after being metabolized it’ll enter your bloodstream and can stay there for a few hours or longer if you’re a regular user.

Remember, the CBD will only be traced if there is THC present. It’s a good practice to check the labels to find this information out and if it is THC-free, you won’t have to worry about testing positive on any type of drug test.

Lifestyle Habits

Certain lifestyle habits can affect the way CBD processes in your body as well. If you are more active, your metabolism is faster which means your body can process CBD a lot faster, making you feel the effects and it leaving your system sooner as well.

If you are not as active you’ll likely see the exact opposite response. Longer processing times and a lower duration of effects.

Will CBD Show Up On a Drug Test?

If you’re taking a CBD product that has any THC and has to be ingested or inhaled, it is possible that it can show up on a drug test.

There are a number of different testing methods that can detect whether or not there is THC in your system. [1]

Blood Test

While this is a possible method for discovering traces of THC in someone’s system, it is less-effective than other methods because THC is only detectable in the plasma for up to five hours.

It is possible for the cannabinoids to remain in your system for up to seven days.

If you reside in a state where cannabis is legal, having a THC blood concentration level of 1 ng/ml to 5 ng/ml can suggest impairment. [2]


While this method of testing is uncommon and as of right now there are no cut-off limits, THC can still be traced in saliva for around 72 hours.

If you are a daily user, it can stay traceable much longer.

Hair Follicle

Once the THC has gone through the bloodstream, it passes to the hair follicles and can be detected up to 90 days after being exposed to it.

Another factor to consider is that marijuana can be traceable in your hair even if you have not physically ingested or inhaled it. Just something as simple as touching it can lead you to test positive.


This is the most common method of testing, especially in the workplace.

If you are not taking CBD on a regular basis, it can be traceable for up to 7 days but if you are a regular user, it can be detected in your system for up to several weeks.

How Long Does It Take for CBD To Kick In?

So, there’s no clear and cut answer to this question.

Exactly how long it takes to feel the effects of CBD is dependent on a number of factors but one of the most important being the form in which you take your CBD.

Below is a list that explains each form of CBD and how long effects can last if the method has THC included.

  • CBD Oil Topicals | 4 or more hours | Unlikely
  • CBD Oil Tinctures | 2-4 hours | Likely
  • CBD Inhalants | 10 minutes – 6 hours | Very likely
  • CBD Capsules | 2-6 hours| Likely
  • CBD Edibles |2-5 hours | Likely

Our suggestion would be to keep your first set of initial doses on the lower end, to see how your body responds to them. Journaling is a great way to keep track of your exact dosages and note how you respond to each one.

Increase or decrease your dosage as needed .

How Long Does CBD Withdrawal Last?

While CBD Oil can be used for a number of different disorders such as, anxiety, insomnia and epilepsy but it can also have withdrawal symptoms as well, these symptoms can include:

  • fogginess
  • irritability
  • lightheadedness
  • Feeling sick on your stomach

Despite these withdrawal symptoms, CBD can also help subside withdrawl symptoms from other medications. When you consume drugs like antidepressants and pain relievers, it can change the chemistry of your brain, as to where your brain and body is more likely to become dependent on the drug.

Final Thoughts

Alright, now knowing how long CBD can last in your system, you should move forward with your decision to use CBD making sure to take into account all of the factors that could affect your experience.

First, you should decide which form of CBD you’d like to use whether it be tinctures or topical CBD cream and from there start slowly introducing your body to cannabidiol by starting with lower dosages and increasing them as you need to.

It is best not to consume CBD Oil if you have a job interview or any other appointments where a drug test is required.

If you are using cannabis medically, it may be best to have a conversation with HR or a manager to understand their policies around their workers consuming cannabis.
