How Long Does CBD Oil Last?

Whether you're looking to use CBD oil for pain or stress, it can be extremely useful. But if you don't know how long these effects last, it can be hard to plan your day to make the most of the CBD oil benefits.

So does CBD oil work? how long does CBD oil last? And what are the factors that influence the onset and duration of the CBD oil effects? Let's take a look.

What this article covers:

How Long Does CBD Oil Stay In Your System?

There is a lot of variation in the answer. During our research, we found that CBD's half-life (the time it takes for a drug's active ingredients to reduce by half) varies greatly, with recent studies putting it anywhere between 1 hour to 5 days. The method of consumption, which we'll cover in detail later, can also affect how long the product stays in your system.

That being said, these are some general time frames to expect from CBD oil. The best way to describe these time frames is to divide them into separate CBD states: the onset of the oil effects and the duration of the effects themselves.

Please note that CBD taken in all forms has a cumulative effect. It can take up to 30-45 days of consistent use for the compound to build up within the body and provide the desired results.


The onset of CBD oil refers to how long it takes for the CBD effects to kick in. Effects can take anywhere from 5 minutes to 4 hours to be felt.

The onset of CBD oil is affected by:

  • Serving size of the CBD
  • CBD oil strengths
  • Method of consumption

The more you take and the higher the potency, the quicker you'll feel the effects. They'll also last longer, which leads to our next point.

The duration refers to the period where you can actively feel the effects of CBD oil. After the onset period, the effects can be felt anywhere between 2 hours to a full day.

Similar to the onset, this is affected by the serving size, the CBD oil strength, and the method of consumption.

How Long Will The CBD Be In Your System?

Even when CBD oil stops working and you no longer feel the effects of the oil, the CBD is still in your system. It can take 4 to 5 half-lives for the CBD to be completely out of your system.

This can be a little bit of an issue, especially if you're worrying about being tested. However, CBD doesn't show up in tests if there is no THC present. If you take CBD with THC, it will show up on tests even a week after consumption.

The more potent the CBD oil (and THC) and the more robust the consumption method, the longer this period will be.

What Factors Influence The CBD In Your System

The above timeframes give you a general idea of what to expect from your CBD.

However, factors like consumption methods and CBD quality affect how long the CBD oil lasts. These factors can also affect how often to use CBD oil and how fast does CBD oil work.

To get a better idea of how long your CBD oil will last, consider these factors and how they play into your CBD consumption practices.


From what we've gathered, food–especially high-fat food–slows down the onset of CBD oil. The more you eat, the longer it takes for the CBD oil to enter the bloodstream and do its thing.

The opposite is also true–if you've been fasting, CBD oil will affect you much quicker. The longer you've been fasting, the faster the onset of the CBD oil.

This doesn't mean the CBD oil potency will be stronger. While it takes longer for CBD to enter the bloodstream of someone that ate food, CBD and high-fat foods lead the higher absorption rates. CBD tends to peak higher and be more potent in the blood of people who've eaten.

CBD also stays present much longer in people who eat before using CBD versus people who didn't eat before taking CBD.

Consumption Frequency

CBD is fat soluble, which means it builds up in the fatty tissue in the body. CBD is known to have a cumulative effect, meaning the more you take it, the more it builds up.

How often should you use CBD oil? We recommend daily use. Using a lot of CBD daily will cause it to build up in the body, and provide longer-lasting relief.

Serving Size

The more CBD oil you consume, the longer the effects will last. It will also be in your system long after the effects have worn off.

Quality & Potency

Good CBD oil is going to have better and longer-lasting effects. They'll be much more consistent in results too. Quality CBD will also have a clear indication of the potency you can expect from the oil, and the higher the potency, the quicker the onset and longer the duration of the effects.

When you buy CBD oil, it's important to check that they contain genuine cannabidiol extract. Why is CBD oil so expensive? It's because high-quality genuine CBD oils with higher potency cost more than inferior products. They'll also have clear indications of how much cannabidiol you'll get per serving.

For example, our high potency 5000mg CBD oil of our CBD therapy oil clearly shows how much CBD you'll get per serving and the potency you can expect.

Low-quality CBD oil might not have any active CBD. So, if you find yourself wondering why CBD oil doesn't work or you're not feeling the effects, it might be that you have a dud.

Always browse the company test results to ensure you only receive the best product and the best effects. All our product information and related studies, from CBD oil percentages to CBD topical balm benefits, are tested and verified.

Consumption Method

CBD oil can be consumed in various methods, all of which have different onset and duration periods. Based on our observations, the most popular are sublingual administration and edibles

Our fastest-acting product is CBD isolate taken sublingually. Take a scoop of the isolate and place it under your tongue for at least 60 seconds before swallowing.

Holding the isolate under your tongue allows for faster absorption because the CBD doesn't have to go through your stomach and digestive system before being absorbed into the bloodstream.

This makes sublingual absorption perfect for when you need relief quickly. You also take CBD oil sublingually holding it under the tongue for 60 seconds to speed absorption.

Next, we have edibles, which can be found in the form of soft gels or gummies. This can take anywhere from 45 minutes to 2 hours to take effect.

But, edibles do come into contact with stomach acid, which degrades the CBD and lowers its bioavailability. If you get softgels, make sure to get softgels that are fast dissolving, like these 30mg CBD softgels. It'll protect the bioavailability and increase the onset time of the effects.

Individual Biology

Finally, individual biology also plays a big role in how the body metabolizes CBD oil. If you have a faster metabolism, your body will shorten the onset and duration of the CBD effects. If you have a higher body mass, it'll take longer for the CBD oil to work.

And then there is how these different factors interact with one another.

Some people might work through CBD much faster than others, and the only real way to know how it will affect you is to slowly introduce CBD to your body. Start with low potency CBD like the 500mg CBD oil and work your way up to oils with a higher CBD oil percentage like the 1250 mg CBD oil.

It's hard to give a definitive answer to how long CBD oil lasts. Factors like consumption method, CBD oil quality, liver function, and individual biology all have an effect, making it impossible to give a one size fits all answer.

However, by slowly introducing CBD oil, taking note of how you react to it, and taking into consideration the above factors, you can determine how your unique body reacts and how long the effects of CBD oil last for you.

The CBD oil benefits list is long and impressive. But CBD doesn't contain THC, so you won't feel “high” in the traditional sense.

CBD is an adaptogenic compound, meaning the effects vary depending on your body's needs.

An adaptogen can be defined as “an agent that supports the body's ability to accommodate varying physical and emotional stresses.” So, the way CBD will feel for you depends on what imbalances you are experiencing and the serving size you take.

CBD is known to be biphasic. This means that CBD can create different effects within the body at different serving sizes.

Small servings can help you to feel alert and focused, whereas larger servings promote relaxation.
