Whether you are a long-term CBD user or just taking your first CBD dosage, you may be wondering, ‘how long does 5mg of CBD stay in your system?’

You can take CBD in many forms including CBD oil, gummies, and capsules. The amount of time CBD stays in the body depends on how much you take, how frequently you use it, and what kind of CBD you use.

Generally, CBD remains in the body for 2 to 5 days, however, this time frame may not apply to everyone. CBD can stay in your system for weeks.

The effects of CBD vary from person to person and depend on many factors. For example, the effects of 5mg CBD can remain for 2 hours, although it can last longer in some people. Furthermore, your CBD tolerance level and metabolism will decide how long CBD will last for you.

If you're wondering what happens to CBD when it enters the body, we've got all the answers.

In this article, we will discuss how CBD is absorbed, metabolized, and eliminated. We will compare several CBD administration methods and how they affect the amount of time CBD remains in your body.

How long does CBD 5mg last?

How long CBD remains in your system is determined by your biology and personal experience. Many CBD products contain THC (the psychoactive cannabinoid), which is metabolized and broken down into various metabolites. These metabolites last longer in your system than THC itself.

Moreover, the strength and potency of CBD are important factors in determining how long they will last. For example, strong CBD products will last longer than less potent ones.

According to CBD consumers, 5mg of CBD can last for about four to six hours, however, it can take 30 to 60 minutes to kick in, depending on the mode of administration. Take one 5mg CBD dosage, then wait an hour before taking another because some people digest CBD more slowly than others.

According to research, a high dose of oral CBD (10 mg/kg/day – approximately 700 mg/day) can last for six weeks. The study found that CBD levels dropped to an average of 1.5 ng/ml one week after taking the last CBD dosage. After about a week, Cannabidiol levels were nearly undetectable.

According to the study, the half-life of CBD is approximately 2-5 days. There are no specific factors that can influence CBD's half-life. However, this half-life is shorter for those who don’t consume CBD on a daily basis.

Factors that Affect How Long CBD Stays in Your System


Purity and Potency of CBD

The higher the concentration of a CBD product, the longer it takes the liver to metabolize it and the longer the active compounds remain in your body.

CBD Dosage

The amount of CBD you take influences how long it stays in your system. The longer you rely on CBD, the longer it may remain in your body.

Like with most drugs, the higher the dose, the longer the CBD remains in the body. However, you must be careful because high doses may cause mild adverse effects, so it is important to choose the appropriate dose for each user.

Moreover, if you take CBD products that contain THC (such as full-spectrum CBD), these compounds can stay in your system for days, weeks, or even months.

THC Potency

Cannabis that contains more than 0.3% of THC falls in the category of Marijuana. There are many cannabis plants that contain more than 0.3% THC content; this type of cannabis delivers a much higher THC content in the bloodstream and bodily tissues. It will not only get you high, but it will also make THC and its metabolites remain in your system for longer.

Your Diet

What you eat, how much you eat, and when you eat, are all important factors. When you take CBD on an empty stomach, it is digested and excreted faster than when you take it on a full stomach, since it will slow down digestion.

Your Genetics

Your genetics play a significant role in how quickly your body breaks cannabinoids (CBD and THC). The enzymes in the liver are responsible for breaking down cannabinoids; however, due to genetic differences, these enzymes act at slightly different rates for everyone. Some people absorb THC faster than others.

Body Composition

Body composition reflects the percentages of water, fat, bone, and muscle in human bodies. Because CBD is fat soluble, small amounts may be stored in fat cells. If you have a high percentage of body fat, cannabis will stay in your body for a little longer. Since THC metabolites are retained in fat cells, heavy users have longer-lasting effects.

Your Metabolism

The rate at which a person digests and excretes CBD is determined by their body's metabolism. Our metabolism is a set of chemical reactions involving the transformation of food into energy. The more quickly your metabolism works, the more quickly chemicals (including CBD) are broken down, digested, and excreted.

How Often Do You Take CBD

How do you consume CBD? And how frequently do you use CBD? These are the most important factors in determining how long CBD will last in your body. The more CBD you take in, the more metabolites you'll have in your system.

The way you ingest CBD not just affects the potency but also the duration of the benefits. The method of ingestion is also related to bioavailability. In general, administration methods with higher bioavailability will be eliminated from the body more quickly.

For example, oral CBD products, such as edibles and pills, can also last longer in your system than CBD smoked or vaped. If you consume CBD on a daily basis, it will most likely stay in your system for longer, usually 10 to 15 days.

When you take CBD (that contains THC) on a weekly basis, your body will clear THC and its metabolites more quickly.

CBD Product Type

CBD can be used in a variety of ways. Everything from the duration of the effects to how long it stays in your body is affected by the method you take.

CBD comes in a variety of forms, including:

  • CBD oil
  • CBD gummies
  • CBD capsules
  • CBD flowers & vapes

How to Get Rid of CBD Oil in Your System?

There are a few tips and tricks that will help you get rid of CBD oil faster.

Drink More Water

Drink plenty of water in the coming days if you don't want to fail a drug test.

The liver contains trace amounts of cannabinoids such as THC, and drinking more water causes the body to discharge more toxins and waste from the liver.

Drinking more fluids improves muscular function, and circulation, regulates blood pressure, and staying hydrated can help you get CBD out of your system faster.


Diuretics are often known as 'water pills' or 'water tablets'. These drugs are used to increase urinary rates.  A diuretic can increase urination, which accelerates toxin excretion. This can help in the removal of CBD from your system.

Eat More Fiber

Eating more fiber can help your body eliminate CBD as quickly as possible, as it is one of the most effective ways to remove CBD from your body. Fiber helps in a number of ways, including improving bowel movements, which allows for faster CBD elimination.

Fiber aids in the removal of CBD from the blood by promoting digestion and metabolic activity. Whole grains, fruits, and vegetables are great sources of fiber.

How Long Does CBD Stay in Your System for a Saliva Test?

If you live in a state where Marijuana is legal, saliva tests used in traffic control could be utilized to determine driving ability.

Saliva tests used in traffic control could be used to determine driving ability in states where marijuana is allowed.

Because saliva tests and drug tests cannot differentiate between THC and marijuana, if you test positive, you will be treated as if you were using marijuana.

However, Marijuana (or THC) can be detected in saliva for several days.

Occasional CBD users: 1 to 3 days

Chronic CBD users: up to 29 days (1 month)


How Long is CBD Detectable in Urine?

CBD can be detected in bodily fluids such as urine and saliva between 1 and 7 days. It can still be detected in hair months later.

How long does 20 mg of CBD stay in your system?

The mode of consumption and CBD product formulation determine how long 20mg CBD remains in your system. CBD users should try fresh and healthy CBD products. However, the effects of 20 mg CBD can stay in your system for 6 to 6 hours.

Bottom Line

CBD is a complex and unique compound that affects each individual differently. So, it’s difficult to determine how long CBD lingers in the body because various factors influence this. Furthermore, each organism may react quite differently to the effects of CBD.

More research is needed to determine the amount of time it takes for CBD to leave your body. However, here is what we know so far:

The 5mg of CBD will not stay in your system for more than 7 days after your last usage unless you are a frequent CBD user (more than 5mg per day for several weeks). In this case, CBD can last up to more than 2 weeks, depending on how frequently you use it.



You're unique.
Your supplements, should be too.
