How long does CBD oil stay in your system?

If you’re a CBD shopper you may find yourself asking “How long does CBD stay in your system?” CBD may not produce the same psychoactive effects as THC, but it does get stored within the body. The amount of time that CBD remains detectable (and felt) depends on a few different factors.

  1. Dosage: a large amount of CBD consumed all at one time will influence how long it remains in your system.
  2. Metabolism: your metabolism plays an important role in how fast anything is metabolized and excreted from the body – CBD is no exception.
  3. Frequency: taking CBD frequently will also influence how long it remains in your body.
  4. Method: the effects and presence of CBD within the body are dependent on how you have introduced it into the body. For example, vaping or smoking CBD will cause an almost instantaneous effect, whereas ingestion will delay the onset by ten minutes to an hour.

Let’s look into how long you can expect to feel the effects of CBD after consumption.

NOTE: consumption method plays a significant role in determining how long it will take to feel the onset of the effects and how long they will last.


Oral ingestion is the most commonly used method of CBD consumption. While this method is convenient, it is not the most effective method – especially for those who want to feel effects immediately.

Swallowing CBD oil prevents it from entering into the bloodstream efficiently. Once swallowed, the CBD will first travel through the digestive tract and eventually end up in the liver. Once in the liver, the CBD will be broken down before finally reaching the bloodstream. Research studies show that when CBD is metabolized by the liver, the compounds go through what is called the “first-pass effect.” Enzymes within the liver will reduce the CBD concentration prior to it finally being sent into the bloodstream and circulated throughout the rest of the body.

So, even though oral consumption is popular due to its ease of use, it can ultimately be inefficient when compared to other methods, such as sublingual or inhalation. Only about 5% of swallowed CBD ends up in your bloodstream – meaning this method of consumption yields very low bioavailability.

Conclusion: Whether ingesting/swallowing CBD oil or snacking on CBD-infused edibles, it will all ultimately go through the same extensive and lengthy digestive process – which will reduce the total concentration of CBD in your bloodstream. Depending on the dose, CBD that is ingested (swallowed) will take anywhere from 1-2 hours for the full effects to set in – and effects should last 1-2 hours thereafter.


The sublingual method is considered more effective than ingestion. “Sublingual” is science-speak for under the tongue. To take CBD oil sublingually, place one full dose under your tongue and hold for 30-90 seconds (the longer the better) before swallowing.

By using this method, CBD is transferred to the bloodstream via your mucous membranes located inside of the mouth. The sublingual method completely bypasses the digestive system and liver – making it very efficient.

Conclusion: Taking CBD sublingually (under the tongue) produces higher bioavailability compared to swallowing or pairing with food and drink. Depending on the dose, the full effects of CBD consumed sublingually should kick in after 10-30 minutes and last for 2-3 hours.


Inhalation is also an effective method when considering taking CBD due to its rapid rate of absorption into the lungs and bloodstream. When CBD is inhaled, it is sent directly to your lungs and then it is absorbed into your bloodstream. Once in the bloodstream, the CBD will be circulated throughout the rest of your body.

Conclusion: Research suggests that CBD reaches its peak blood concentration within three minutes after inhalation. This is an extremely rapid onset of effects. The effects of CBD when inhaled should last anywhere from 45 minutes to two hours thereafter.

Now, let’s look into how long CBD will remain stored in the body after consumption.

Also, will CBD show up on a drug test?

It is highly unlikely that CBD will cause a positive test result in a drug screening, as most drug tests look specifically for the presence of THC or other specific illegal substances. Legally, hemp-derived CBD products must contain less than 0.3% THC. If that number is still too high for your comfort – aim for the Isolate form of CBD.

Isolates contain 0.0% THC and are the safest option for those concerned with drug screenings. All three products in a Nature’s CBD Box subscription are CBD Isolates and are 100% THC-free.

This all being said, Isolate or not – CBD will remain stored in the body anywhere from one to two weeks post-consumption.

To wrap things up…

CBD can be felt anywhere from 1-3 hours after consumption, but it can remain stored in the body (detectable) anywhere from 1-2 weeks. This timeframe can change depending on a variety of different factors including: consumption method, frequency of use, dosage, and metabolism.
