After several studies, a test was conducted on patients that were given a high dose (700mg per day) of CBD for six weeks. After a week, they were tested, and it was discovered that in most cases it takes about 3-5 days for CBD to leave the body entirely.

You might be wondering:

“…does this work for everyone?”


…this time range may not work for everyone because the mode of use and the chemical make-up of the human body are entirely different. But it has been established that the maximum time frame for CBD to stay in your system is not more than a week.

Researchers are still relentlessly looking for the unknown to help give a specific answer to how long CBD last in the body. But at the moment, we can only provide a general estimate base on experiences and scientific discoveries.

Your choice of taking CBD is also a great deal which determines the length of time it would stay in your system.

CBD can be taken through inhalation which is also known as vaping or smoking while other products are available in a non-inhalable form.

Some products such as tincture are taken sublingually under the tongue, while some are applied topically on the outer part of the skin. There are products manufactured in the form of capsules and edibles that can be ingested through the digestive tract.

What’s the bottom line?

Manufacturers of CBD have made available several CBD products which offer different methods of ingestion. To help understand different methods of ingesting CBD, we will explore each method by discussing them extensively and how they affect CBD bioavailability.

Four different methods of CBD ingestion (infographic)


Inhalation is also known as vaping is considered the easiest and the most popular way of consuming CBD. It is a relaxing method that acts fast when inhaled. Many people enjoy vape oil through the use of vaporizer (Vape pen). The bioavailability of inhalation of CBD is high so far oxygen is entering the bloodstream directly.

This method is ideal when considering a faster effect and a quick fix. But how long doe CBD vape stay in the body? The effect of CBD vape last anytime from 1-4 hours and in most cases, it stays 3-4 days in the body according to experts.


The sublingual method is a means of consuming CBD by dripping a few drops under the tongue in which is swallowed after some few seconds. It is performed with the tincture, CBD sprays, and CBD concentrates.

CBD substance is absorbed through the mucous membrane under the tongue and diffused by the capillaries in the tissue which channels the substance to the bloodstream. The length at which CBD tincture stays in the body is similar to that of vaping.

Aside inhalation, a sublingual method is also a fast onset with a high bioavailability compared to oral consumption.

Within 20-30 minutes of CBD usage, you can expect to feel the reaction and the effect may last within 4-6 hours and it takes about 4-5 days for CBD and it’s remnant to exit the body system.


Topical comes in the form of balm, ointment, and cream which is usually applied to the skin to remedy inflammations and some other skin discomfort. It can also be applied to stiff joints and skin irritations such as eczema, acne, wrinkle and so on.

This method of application is slower but has a long-lasting effect that might take up to 5-6 hours. Topical takes a gradual process before you feel the effect. It’s remnant or fluid still remains in the body and stays up to 2-5days when a moderate CBD is used.


CBD can also be ingested through the use of CBD capsule, edibles, and various gummies bears. This method is popular because it comes with ease and many people are familiar with this form of CBD.

For those who would prefer to taste CBD, this method of consumption is the best. When you consume CBD orally, it passes through the digestive tract and circulates into the bloodstream.

Fast metabolism and healthy digestive system help to deliver actual effect of CBD, especially with edibles.

Some people prefer to prepare their edibles by making cookies, brownies or their food with CBD. Either way, depending on the amount of CBD you use, this method of application is the slowest and might take as much as an hour or two hours for edibles and capsule to start taking effect.

The time frame at which CBD edibles stay in the body might also take up to 3days and not more than 5days but the effect last up 6-8 hours.


Will CBD show in your drug test?

CBD is an extract of cannabis strain with a very low THC that is not more than 0.3%. When CBD is concentrated, there is every possibility that the little THC present in it will also be concentrated.

This is crazy, right?

Here is the kicker.

A person that consumes a high-quality scientifically vetted hemp extract at an optimal serving size will not test positive for drugs. But a person that consumes an extremely high dose of CBD will test false-positive.

Therefore, theoretically, the consumption of a high dosage of CBD from 1000-2000mg per day would consume 3-6mg of THC. This is a high dose that can make a person fail a urine test for drugs.

But this is the real deal! 

Companies don’t conduct a drug test for CBD but administer the test for THC, the psychotropic compound that is responsible for marijuana psychoactivity present in the cannabis plant.

The drug test was not designed to detect CBD. Drug screening is mostly carried out by employers for safety, legal protection and federal mandates to be sure that their employees are in a good mental state of health.

So far there is no definite amount of time CBD stays in the system then necessary precautions need to be taken. When a drug test is mandated, it is advisable to know the regulations guiding the organization or companies that require a drug test.

Want to know the most amazing part?

CBD cannot alter the psychological state of the consumer, there is no point drug testing for CBD.


What is the optimal CBD dosage for you?

Cannabis is a natural supplement and personalized medicine for therapeutic values. Your sensitivity to CBD especially the THC contained in it determines the appropriate ration of CBD is consumed at a goal.

What is the optimal CBD dosage for you?


An effective dosage can range from little milligram to a gram or more of CBD. Some people don’t have a specific dose they work with; all they do is to take what gives them the intended relief.

You know what?

It is advisable to start with a few drops of doses for some days and observe the effect which afterward you can decide what work best for you.

Cannabis compound has a biphasic compound which means a moderate dose can be of great benefit and a high dose can create an opposite effect. CBD is known with no adverse effect, but an excessive dose of it may not offer the supposed therapeutic effect.


Final thought

CBD is a non-psychoactive substance mainly used for medical and recreational purposes. CBD is also known for its therapeutic properties which make it a well-accepted remedy for health and wellness.

Despite handful knowledge about the benefits of CBD, there has not been any definite information as regards the accuracy of the length at which it can stay in the body.

But based on random estimation, the length at which CBD last in the system varies depending on the method of use. But with the clinical trial carried out on some patients who used CBD, it was evident that CBD stays 3-5 days in the system.

Several types of research are still going on which is an edifice of hope that sometimes soon; there will be factual information on how long CBD stays in the body.
