How Long Does 5mg Of CBD Stay In Your System?

Cannabidiol (CBD is a major component found in cannabis after THC. However, unlike THC, the effects of CBD will not give you a high. It is one of the major reasons why CBD has a higher preference over THC for medicinal purposes. But, those still unaware of its products can have some reservations about its use. Thankfully, there is no need for concern as we will cover all the related queries so that you can make more informed decisions. 

The first question that may come to your mind would be, “Is it safe to use CBD?” Let’s see

Is CBD Safe To Use?

For the most part, it is safe to use CBD in any form. It is because the products that contain CBD have more than 97% CBD in them. Some good brands even offer 100% CBD which is very helpful for many situations, such as pain relief, relaxation from mental stress, and many others. CBD products are legal in many parts of the US, but it still does not have the approval of the FDA. It also does not prove anything about the effectiveness of its products. 

In the coming sections, we will also take a look at the benefits of CBD and what method of consumption would be the best. 

Even though it is okay to use CBD products in general, there are specific situations where it is not. We would advise you not to use CBD in any way if:

  • You are a pregnant/breastfeeding woman. 
  • You are already on other medication 
  • You have weak immunity

If you have doubt in your mind or have any medical condition, it is always better to consult a medical expert before using CBD products. One more thing that is very important is that you should always use a product from a reputed brand and make sure that the product is of the highest quality. It is a good idea to go for products with 0%THC, but up to 3%THC is also a good option.

Benefits Of CBD 

There are a lot of benefits that you can associate with the use of CBD. It is mostly its health benefits that we are talking about. Let’s have a look at them. 

Helping With Anxiety And Depression

 The ability of CBD to provide mental relief is quite popular, and it is a big reason for its consumption. There have been many tests where its stress-relieving properties came out on top. One such study was done in 2017 in the Brazilian Journal of Psychiatry. Fifty-seven men were put up in a simulation of a public speaking test, and they all got different doses of CBD before the speeches. While everyone’s experience was a reduction in anxiety, those who had taken the 300 mg dose showed significantly lower stress than their 150 mg and 600 mg counterparts. 

Reduction In PTSD Symptoms

There was a study in 2018 where 11 people with PTSD received CBD with routine psychiatric care that ran for eight weeks. Only one out of those patients did not experience a decrease in PTSD symptoms; the other 10 had a reduction in their symptoms. CBD was tolerated very well, is what the researchers wrote. 

While CBD may not cure the symptoms completely, it can, generally, reduce the level of anxiety. That is why Margaret Rajnic, a doctor of nursing practice, emphasizes using CBD alongside the standard therapy for PTSD patients. 

Many other similar trials have also given similar results of reduction in PTSD symptoms. 

Pain Relief

It is also a widely known factor in the consumption of CBD. But, it is not just the simple body pain that is affected. In 2007, Canada approved the use against cancer pain that was unresponsive to any other medicine. There are many studies that are indicative of its effect on chronic pain.   

Medical experts conducted research in 2020 with patients having symptomatic peripheral neuropathy. The patients with the CBD dosage saw significant improvement in their intense, sharp pain. There was no report of any side effects. 

Reduced Diabetic Behavior

Tests conducted on human cells showed that CBD could help in the reduction of the effects of high glucose levels on other cells of the body. These cells are usually the ones responsible for the development of diabetes and related complications. 

There was another study with 13 patients having type 2 diabetes who were given CBD instead of their usual insulin treatment. They found in that study that CBD helped reduce resistin and increased their glucose-dependent insulinotropic peptide. The results suggest that CBD can be used to treat diabetic patients by helping the body regulate insulin-related hormones.

Treatment Of Opioid Addiction

Many human and animal trials suggest the use of CBD for the treatment of opioid-dependent patients. There was one such study where people with heroin use disorder received CBD. In the span of one week, there was a significant improvement in cue-induced cravings, resting heart rate, withdrawal anxiety, and salivary cortisol levels of the users. There were no severe adverse effects in that trial. 

Other studies have found a reduction in anxiety, improved sleep, and reduced pain in patients having substance use disorders. All these trials suggest the use of CBD for treating opioid addiction.  

Protecting Neurological Patients

Studies show that CBD acts as an antioxidant and also has anti-inflammatory properties. These are the characteristics that can provide protection against neuroprotection and many other pathological disorders. Some studies also suggest that it can be helpful against Parkinson’s disease, multiple sclerosis, and Alzheimer’s.

Best Method To Consume CBD 

There are plenty of ways in which you can use CBD. Earlier, there were full and broad spectrums and Isolates. Here are some of those methods; you can see which suits you best. Nowadays, these are the major available forms:

  • CBD Patches: This form of CBD has direct application on the skin. It is best for those who have a weak stomach. The patch diffuses the CBD directly into the bloodstream, with a downside being that it can take a long time. It is a good idea to apply it on the part of the skin where there is no hair, sweat, or any unwanted particles. 
  • CBD Oils or Gummies: This method of consumption provides you with an edible option. These are good because the time it takes is much lesser than patches. However, they also have a downside: some or a lot of CBD can get lost through excretion.  
  • CBD Isolate Powder: Mixing it with food, tea, or soup is some of the available options. It is a pure form of CBD, which makes it easier to mix it. 

There is also a full and broad spectrum, as mentioned above. They are two different types where the amount of THC is different. Full-spectrum CBD has less than 0.3% THC, whereas the Broad spectrum has traceable amounts of THC in it. The Federal law also allows the use of CBD with less than 0.3%THC. 

How Long Does The Effect Of CBD Last? 

On a general note, the effects of CBD can stay up to 3 days in our body system. But the amount is subject to variation depending on the amount of dosage and the form of CBD intake. However, it only lasts for approximately one day in the bloodstream. The effects of CBD usually last for 4-5 half-lives of CBD. 

The term half-life implies the duration that the body can take to eliminate one-half of a substance or chemical. The time equivalent of one half-life of CBD ranges from an hour to 5 days. 

There was a study that stated that smoking or inhaling CBD makes it enter directly into the bloodstream, and that is also the reason why it can leave the body quicker in such cases. On the contrary, the edible versions of CBD tend to last longer. The half-life in the consumption of CBD smoking is 31 hours, and in oral CBD products, it can range from 2 – 5 days. The half-life of CBD is in the range of 1.4 – 10.9 hours if the consumption is in the form of CBD spray or drop. 

One other factor that can affect the duration of CBD in our body is the frequency of consumption. Frequent users of CBD are seen to have difficulty in detection time. It is because the solubility of CBD in fats allows it to accumulate in fat tissues. Thus we can deduce that it stays longer in the bodies of chronic users of CBD rather than acute ones.  

How Does CBD Affect The Brain?

A research in 1990 on THC discovered the endocannabinoid system (ECS). Our body’s capacity to make molecules similar to cannabinoids was found in that study. These molecules provide support to the immune system, and once they complete their function in the body, they get broken down.

Our body and the central nervous system (CNS) have receptors for endocannabinoids. THC can bind to these receptors, contrary to CBD, which weakly binds or does not bind at all. In fact, CBD can reduce the effects of THC by blocking it. CBD can also affect our brains by influencing the release of neurotransmitters that cause pain, sleep, anxiety, and other functions. 

Factors That Influence Detoxing from CBD

It is a general idea that CBD has a half-life of 1-2 days, irrespective of gender, which means that half of the CBD in our body gets eliminated in that time. But, it doesn’t mean that is the only borderline duration as there are several factors that can influence the time of elimination of CBD from our body. These are:

  • Weight – CBD is fat-soluble and is stored in fatty tissue
  • Frequency of use – CBD can accumulate in your system
  • Mode of ingestion
  • Dosage
  • Potency
  • Metabolism
  • Age
  • Genetics

How Long Does CBD Stays In Different Body Components

Every individual is different, and their body’s capacity also differs with them. This is the same with the effect of CBD as well. Many aspects, like hydration, body mass index, and metabolism, can affect the duration of CBD in your body. For example, a faster metabolism can make it leave our system faster.  

Let’s check how long it stays in different components of our body. 


Hairs are said to contain CBD for longer periods of time which can extend up to three months. That is why many tests use hair as a medium to detect CBD. 


Urine tests are also very popular for drug screening. However, the detection in urine can depend on the frequency of consumption. The typical detection range of CBD in urine tests is three days to two weeks. But, these numbers can vary based on the frequency. 


CBD does not last too long in the bloodstream, and that is why blood tests are not preferred for the detection of CBD. The time duration in the blood is from five hours to a week. 


Saliva tests are also very rare for the detection of CBD. It can last in the saliva from a few minutes to 36 hours. It is also the reason why saliva tests are not preferred. 

How Long Does 5mg Of CBD Last?

CBD can remain in our system even if the effects wear off. It is valid for any substance that gets into our bodies. It is all due to the half-life of a substance. Different substances have different half-life duration. There is still no certainty on the exact half-life of CBD, but the estimates say it is about 18-32 hours. Some others say that it is in the range of 1-2 days.  

To give you an estimate on the half-life of 5mg CBD dosage, let’s assume that the half-life is 24 hours. The following table will show you the elimination time and quantity of a 5mg dosage.

Time After Consumption

Quantity Of CBD Remaining (in mg)
0 hours 5
24 hours 2.5
48 hours 1.25 
72 hours 0.625
96 hours 0.3125
120 hours


As you can see, it will continue to go down and even though there is no exact number, roughly 5 days can eliminate CBD from our body. 


CBD is starting to get popular, and there is not much doubt that more and more people are shifting toward it. However, they still need to be cautious with its usage. But overall, it is a really good option to go for pain relief and relief from mental stress. There are many benefits to it that we just mentioned in the blog. 

There is still a need for wide-scale human trials to test CBD’s effectiveness to get it approved for greater medical usage. However, it is quite safe to use from the point of view of an average person. 

We hope that we were able to answer some of your questions related to CBD usage. If there are still any left, you can check the FAQ section coming next.
