However, while many have started their CBD journey without a second thought, others are put off by fears around how long it will stay in their system, something that could pose issues when it comes to things like drug tests. After all, CBD comes from the hemp plant, which can naturally contain THC, the psychoactive compound that itself is detectable in your system for up to 30 days.
That said, CBD products sold in the UK shouldn’t have THC in them, and CBD itself doesn’t show up on a drug test. CBD can stay in your system for two to five days, however, this is dependent on several factors that we’ll explore in this guide.
Which factors affect how long CBD stays in your system?
While two to five days is the typical range for how long CBD stays in your system, the durations can be impacted by the following aspects:
Like with most substances, the higher the dosage of CBD you take, the longer it will stay in your system. Here at TRIP, we recommend taking 15 to 30mg a day at first, before increasing in increments of 5mg each week after the first seven days. For reference, one full dropper of our original CBD oil contains 20mg CBD, while there’s 66mg CBD in the strong version.
The frequency of consumption
How often you take CBD will also impact the time it stays in your system. The compound builds up in your body over time if taken regularly, meaning, the more you take CBD, the longer it will stay there. If you only use it from time-to-time, however, it’ll clear your system pretty quickly.
No two people are the same, and our different body types mean that CBD will impact people in different ways. Aspects like your body mass index, water content and metabolism are just a few of the things that will affect how long CBD stays in your system. For example, the faster your metabolism, the quicker it will pass through.
The food you eat, how much you eat, and when you eat can all impact how long CBD stays in your system. Say you consume CBD on an empty stomach, it will get metabolised and eliminated quicker than if you had it in a full stomach, which would slow its digestion.
The method of use
There are numerous ways to take CBD, from oils and drinks, to vaping and edibles, and which method you choose will again affect how long CBD remains in your body. For example, when vaping CBD, it enters your lungs and takes effect quickly, meaning it won’t stay in your system too long. Whereas, if you ate a CBD edible, you’re relying on your digestive system to metabolise it, which can take some time.
How long does it take for CBD to work?
For CBD to work, it must be able to reach the relevant receptors in the body, which is typically achieved through absorption into the bloodstream. Most people take it via CBD oil, which can take between 15 and 60 minutes to absorb. Again, aspects like weight and genetics impact this and it can take up to an hour for CBD to start working overall.
That said, some methods are much quicker — for example, CBD can be absorbed into the bloodstream in just three minutes by vaping it.

How long do the effects of CBD last?
Again, how long CBD’s effects last depends on aspects like the dosage, your body and the method of use. As a general rule of thumb though, you should feel the effects of CBD for between two to six hours.
Does CBD show up in drug tests?
Even if you have lots of CBD in your system, it shouldn’t show up on a drug test. However, the issue with taking some CBD products is that they may contain THC, which will show up. Some products have traces of the psychoactive compound, so it’s important to be able to differentiate between the different types of CBD products so that you can avoid the risk of accidentally consuming THC. The three main types are:
- Full spectrum CBD - These products include all of the naturally occurring compounds from the plant they’re extracted from, including THC.
- Broad spectrum CBD - Broad spectrum CBD products are similar to full spectrum types, but go through a process to remove the THC. However, trace amounts may still be identifiable in a drug test.
- CBD isolate - These products contain CBD only.
It’s a good idea to avoid full or broad spectrum CBD products and stick with CBD isolate products if you don’t want to risk testing positive for THC. Here at TRIP, we ensure the purity of our CBD products with third party lab testing, so there’s no possibility that you’ll fail a drug test after consuming them.
How long is CBD detectable in urine?
Research on how long CBD stays in a person’s urine is limited. However, one study from 2016 found that subjects tested positive for CBD metabolites within two hours of administration, but flushed it out of their bodies within 24 hours.
How long does CBD stay in your blood?
While not as common as urine tests, blood tests can be used to detect THC metabolites from CBD oil. However, THC and CBD are very quickly eliminated from the bloodstream, which is why urine tests are the preferred method of testing. Overall, THC and CBD are only detectable in your blood for up to five hours after you take them, though their metabolites can be present for up to a week.
How long does CBD stay in your saliva?
Analysing saliva to detect CBD is rare, meaning there isn’t any information out there on how long it stays in your body this way. However, if the CBD product you take contains enough THC for it to be detectable, the psychoactive compound can be found in saliva for up to 72 hours.
In order to ensure you don’t mistakenly consume THC when using CBD, it’s recommended to always buy CBD products from reputable, trusted brands. Be sure to check that the seller you choose is following the necessary regulations and has a COA (Certificate of Analysis) that confirms what they’re advertising is legitimate.
