How long does hemp seed stay in your system?

Cannabidiol (CBD), a non-intoxicating compound found in the cannabis plant, may potentially relieve mild pain and anxiety. While many people are using CBD for these potential benefits, the fear of failing a drug test looms large for others. Because even with the legalization of hemp-derived CBD products in the US, there’s still some uncertainty about how CBD interacts with the body.

Here, we’ll cover the existing research on CBD and its interaction with the human body as well as what factors can affect how long CBD stays in your system.

How long does CBD oil stay in your system?

CBD may not produce the same intoxicating effects as THC, but it does get stored in the body. The time that CBD remains detectable in the body depends on several factors.

A person’s metabolism plays a prominent role in how fast CBD is metabolized and eventually excreted from the body.

Using CBD frequently will also influence the amount of time it remains in the body.

A large amount of CBD taken at a time will influence how long the cannabinoid remains in the system.

Method of administration: Both the effects of CBD and its presence in the body are contingent on how the cannabinoid is introduced into the body. For instance, smoking or vaping CBD allows it to take effect almost immediately, while ingestion will delay the onset for an hour or two.

A 1991 study published in Pharmacology Biochemistry & Behavior examined the concentration of CBD in the blood after high doses daily. Over a six-week period, the research team administered a daily dose of 700 milligrams of CBD to 14 Huntington’s disease patients. One week after the dosing ceased, the CBD remaining in the blood was just 1.5 nanograms per milliliter and was “virtually undetectable” thereafter.

 While the time that CBD is detectable in the body will depend on the aforementioned factors, we can deduce that CBD will likely leave the system after a week or two.

How long is CBD detectable in urine?

We have some insight into how long CBD remains in the blood, but there is little research on how long CBD is detectable in urine. In a 2016 study published in the Journal of Pain, participants were given different types of CBD-rich cannabis products, including oils, capsules, and flower. Two hours after administration, urine samples from all 15 subjects tested positive for CBD. The researchers followed one participant after the last day of administration and found that CBD was no longer detectable in the urine after 24 hours.

It’s important to note that, while existing evidence shows us that CBD can definitely be detected in the body for a certain period of time, most drug tests specifically look for the presence of THC. Therefore, accurate information on how long CBD stays in the body remains limited compared with information on THC.

Apart from the one study that showed CBD was no longer detectable in urine after 24 hours, there isn’t much research on drug testing for CBD in urine.

How long do CBD oil effects last?

The consumption method plays a crucial role in determining how long it will take to feel the effects of CBD and how long they will last.


Oral ingestion is the most common method of CBD consumption. Administering a couple of drops of CBD oil directly into the mouth is certainly a convenient way to reap the potential benefits of this therapeutic cannabinoid. However, ingestion is not necessarily the most effective consumption method for those who want to feel the effects of CBD immediately.

Swallowing CBD oil prevents the cannabinoid from entering the bloodstream right away. Instead, it will travel first through the digestive tract and eventually on to the liver, where it will be broken down before finally reaching the bloodstream.

With ingestion, it could take anywhere from one to two hours before the effects of CBD finally set in.

Studies show that when the liver metabolizes CBD compounds, they undergo what is called the “first-pass effect.” Enzymes in the liver reduce CBD concentration before the remainder is finally sent to the bloodstream and circulated throughout the body. While oral consumption of CBD has become popular for its ease of use, it can be an inefficient method of consumption compared with inhalation or sublingual administration. This is because only about 5% of swallowed CBD ends up in the bloodstream, meaning this method provides low bioavailability.

Whether you’re ingesting CBD oil or CBD-infused edibles, it ultimately goes through the same lengthy digestive process, reducing the total CBD concentration in the bloodstream. With ingestion, it could take anywhere from one to two hours before the effects of CBD finally set in. From there, you may feel the effects for one hour to several hours, depending on the dose and your response to CBD.

How to Select the Best Hemp Oil Seller?

Now that you know how long hemp oil will last in your body, it is important to understand one more thing: the need to only use the best quality. You can only be sure of getting high-quality hemp oil by selecting the best seller. So here are some useful tips to help you identify the best seller:

 Make sure to only purchase oil from naturally grown hemp plants. This is critical in ensuring that the hemp oil and water based cannabinoid products do not contain pesticides and other contaminants. These contaminants mainly get into the hemp plant in the farm and find their way into the final hemp oil.

Today, many companies are using advanced technologies to help enhance the bioavailability of cannabinoids. Therefore, you should only consider buying from companies that use technologies such as water based pharmaceutical technology.

Buy hemp oil and water based hemp products that are tested to be free from heavy metals. If the hemp plant used to extract the hemp oil had dangerous heavy metals such as lead and arsenic, they can easily find their way into the final products. As such, you should choose a seller who works with manufacturers who identify and isolate these dangerous compounds.

Go for sellers who provide third-party testing certificates. This certificate indicates the content of hemp oil or water based cannabinoid products, and also helps to indicate if the hemp oil or water based cannabinoid products have the right levels of THC (less than 0.3%).

Only buy from companies that have demonstrated commitment to customer value. As more companies enter the hemp niche, you should do your research well to know the one that is committed to customer value. For example, is the company driven by a commitment to customer satisfaction? If the feedback from previous customers was positive, you can also anticipate getting good results. But if the feedback was poor, you are likely to also get disappointed. 

The length of time that the hemp oil takes in the body is dependent on several factors, including your metabolism and method of ingestion. Remember that if you want to get the best results from using hemp products, you should only buy from the best sellers in the market.
