It is well-known that vaping is the fastest way to get CBD into your system as it is quickly absorbed by the body through the lungs and into the bloodstream, allowing users to get effective results. If you already vape CBD, or are thinking that it might be the right method for you to consume CBD, you may be wondering how long cannabidiol stays in your system after a vaping session.

Whether CBD is being used for its potential health benefits of reducing the symptoms of anxiety, pain relief, or for better sleep, it’s important to know how long CBD can stay in your system. In this guide we focus on:

  • How long does CBD vape stay in your body?
  • What is the half life of CBD?
  • How long can CBD be detected in the body?

How long does CBD vape stay in your body?

When you vape CBD, it is heated to a high enough temperature that the e-liquid turns into a vapour that is inhaled into the lungs and quickly into the bloodstream to take effect. CBD from a puff on a vape pen enters your system in around fifteen to thirty minutes, depending on a range of personal factors, and users often feel the effects for around 2-6 hours later. If you have just one puff, it may have already left your system by this time.

If you vape more CBD than this, how long it stays in your body is dependant on a range of factors including:

  • CBD strength: The more CBD you have inhaled in a session or over a certain period of time, the longer it will take to leave your system, as more will accumulate in your body with the need to be broken down.
  • Frequency of vaping: The CBD from one vaping session may stay in your system for between 2-4 days, depending on strength, but if you vape daily or multiple times a day, then it may be present for 10 days, or even up to 30 days after you have stopped vaping.
  • Each individual’s body chemistry: CBD is broken down in the body by enzymes in the liver, and this process will take less or more time depending on your unique metabolism. The faster your metabolism, the sooner CBD will be eliminated.
  • Body mass index: Weight and height also impacts how long CBD stays in your system. As CBD is a fat soluble compound, people with more body fat will retain CBD for longer.
  • Age: As metabolism generally slows down the older an individual gets, how long CBD stays in your system as you age will change, and likely means it’ll stay for longer.
  • Whether you’ve eaten before vaping: CBD will be eliminated by the body faster on an empty stomach if you haven’t eaten before vaping, as opposed to having a full stomach. How long it takes in each instance will depend on the individual.

In essence, how long CBD can stay in your system is a complicated question with no definitive answer. Whilst you may feel the effects for up to 6 hours, it can remain in your system for 2-4 days, or 10 days depending on use, and if you inhale high doses of CBD frequently, it can accumulate in your body and stay in your system for 30 days.

For you to get a clearer idea of whether it would take more or less time for vaped CBD to leave your system, consider all of the factors that impact this, and make a judgement on if you feel you’d be on the shorter or the longer end of the scale.

How can you speed up CBD leaving your system?

If you are worried about having cannabidiol in your body, you can try to drink plenty of fluids and exercise to flush CBD from your system, and to increase your metabolism. However, it would be difficult to assess how successful you have been and whether it has indeed sped up the process.

What is the half life of CBD?

The CBD half life is the time it takes for your body to eliminate half of the CBD in your system. The half life of CBD is typically around 1-2 days, but it can vary depending on a number of factors, including your metabolism, weight, and overall health. Metabolism is a really important factor to consider as the faster the liver enzymes can break down the CBD in your system, then the less time it will be present in your body and the sooner it will be flushed out.

Again, whilst it’s very dependant on each person’s body and it’s processes, CBD is typically in your system for up to 2-4 days (accounting for a half life of around 1-2 days), but this increases based on how much CBD has been vaped and the frequency with which it has been vaped.

How long can CBD be detected in your body?

CBD can be detected in your system for up to 30 days after you last vape it, depending on how much CBD enters your body and accumulates. However, it’s important to know that the amount of CBD that can be detected decreases over time. After 2 weeks, the amount of CBD that can be detected is typically very low.

How can CBD be detected?

You may be wondering if CBD detection can take place with:

  • Urine tests
  • Blood tests
  • Drug tests

Essentially, a routine urine or blood test won’t look for CBD and a specific test would need to be ordered, so whilst it can be detected in these methods, it typically won’t be.

Routine drug tests are also unlikely to detect CBD simply, again, because they aren’t looking for it; CBD, one of the naturally occurring compounds in hemp plants, is non-psychoactive. However, drug tests may be capable of detecting THC, tetrahydrocannabinol, a psychoactive compound that is present in full spectrum CBD products and broad spectrum CBD products.

If you have taken these types of CBD vapes, then you will have a very small amount of THC in your system, especially as UK products can only contain trace amounts. Once again, it is unlikely to be picked up as you would have to have consumed very large quantities of CBD e-liquids, much more than you would need to take regularly to feel reported effects.

How long does CBD affect the brain?

When you consume CBD, it enters the body and it is thought to affect the brain by working with receptors, reducing inflammation, and altering the flow of blood. Whilst more research is needed, it is often stated that this is perhaps why CBD is reported as being useful for people looking to reduce the symptoms of anxiety.

In terms of how long does CBD stay and affect the brain, it will depend on an individual’s body system and the range of factors we have discussed. However, most people stop feeling the effects of vaping CBD 2-6 hours after use, and the amount in the human body after the half life of CBD is unlikely to have any noticeable effects.


CBD vaping works by vape pens heating up CBD e-liquids to high enough temperatures that the liquid turns into a vapour that can be inhaled. Once inhaled, it quickly enters the body’s system via the lungs. As it is the fastest way to feel the reported effects of CBD, it is a very popular method of CBD consumption.

Beginners should start with low strength CBD e-liquids, gradually increasing until they get the desired effects. It may also be beneficial for new starters to try disposable vape pens, which require no preparation.

It is very unlikely that a person would test positive in a drug test, or fail a drug test from vaping CBD. This is because CBD isn’t looked for in routine tests as it is non-psychoactive. It is possible that THC could be picked up but a person would have to have consumed CBD products containing THC, such as full spectrum and broad spectrum e-liquids, and in very large quantities that are much more than needed.


How long CBD remains in the human body can vary from a few hours to 30 days, however generally it is thought it will stay in your system for around 2-4 days. For each individual, there is no guaranteed length of time as it depends on many factors including your dose of CBD, the frequency in which you consume CBD, how your body processes CBD, your metabolism, age, height and weight.

Whilst it is possible to detect CBD in your system for up to around 30 days, it is very unlikely that a routine test would look for cannabidiol. However, if you have vaped large amounts of broad spectrum CBD or full spectrum CBD, it is possible but unlikely that a drug test could pick up THC.
