How Long Does CBD Last?

Cannabidiol (CBD) has become incredibly popular as a remedy for a plethora of health issues and lifestyle problems. Its many health benefits and therapeutic effects have found legions of fans and it has steadily become a safer alternative to opioid-based painkillers. 

Increased interest in CBD oil tends to raise many questions, with one of the most common being, “how long does CBD last?” If you’ve never taken cannabidiol (CBD) before, knowing how long its effects will linger is important for nailing down your ideal dosage, and ultimately deciding if CBD oil is right for you.

How Long Do the Effects of CBD Last?


Usually the effects of CBD are felt for approximately 4-6 hours. However, this does depend on the strength of the dose, with stronger doses lasting longer.

To accommodate this duration period, it’s common to see people in CBD communities choose to take a morning and evening dose daily, particularly for ongoing issues, such as anxiety or chronic pain.

How the CBD was administered impacts the duration of its effects as well. Ingesting CBD, either with edibles or capsules, takes longer to take effect, but also lasts for longer compared to other methods of taking CBD. When CBD products are ingested, they must first be digested and processed by the liver before making it to the bloodstream, which is when their effects can first be felt in the body.

In comparison, when administering CBD using a tincture product sublingually (using a dropper under the tongue), by vaping or smoking, CBD is absorbed into the bloodstream much more rapidly and the effects of the CBD are felt much faster.

Factors that Affect How Long CBD Lasts

How you choose to take CBD oil is not the only factor that determines the duration of its effects.

Other factors that affect how long CBD lasts in the body include body weight, certain lifestyle choices, how frequently you use it, and dosage.

Your Body Weight

Cannabidiol (CBD) is a fat-soluble compound. What this means is that it is stored in the body’s fat cells. With any fat-soluble substance, like vitamin D or vitamin K, weight plays a role in CBD oil’s rate of metabolization.

If you’re on the leaner side with a lower body fat percentage, CBD’s effects may not last as long as in a person with a higher body fat percentage. Typically, people with more muscle than fat have a higher metabolic rate which means substances like CBD oil will be processed through the body much faster, reducing the duration of their effects.

Your Lifestyle

Another factor that plays a role in how long CBD lasts in the body is lifestyle and activity level. If you lead an active lifestyle, your body is likely to process CBD more quickly because your metabolism will be faster, resulting in a reduced duration of effect.

Your Frequency of Use

The frequency with which you use CBD oil can influence its effects. Unlike other substances, it is unlikely that you will build a tolerance to CBD. In fact, it’s theorized that CBD creates a “reverse tolerance.” Simply put, with repeated use of CBD oil, it is likely that you will require less to feel the desired effects over time. It is believed that CBD increases the presence of naturally produced endocannabinoids in the body, so as your body adapts to create equilibrium, you require less to get the same effects.

If you take CBD regularly, the reverse tolerance you build could cause you to feel its effects for a shorter perceived amount of time.

Your Dosage

The more CBD oil you take, the longer it will take for your body to process it, and the longer the effects will last.

However, it is recommended that you begin with the lowest recommended dose on your CBD oil product. Until you know how CBD oil will impact you, it is best to take it slow.

How Long Does CBD Stay in Your Body?


In general, it takes around five to twenty minutes for CBD to begin to take effect in your body upon consumption. Surely, factors such as the size of the dosage and product potency make a difference. Still, as an average, the effects of most regular CBD doses last between two to four hours.

Most people assume that once the product’s effects have gone, so has the cannabinoid itself. However, even if you don’t feel the effects of CBD, it doesn’t mean the substance has left your system entirely. Over some time, the quantity of CBD in your system gradually reduces as it is expelled from the body. However, this is a slower process than most people imagine.

According to some experts, CBD takes between three to four days to exit your body completely. However, as we have already told you, a variety of different factors influence the effect of substances in your body. In any case, CBD doesn’t take any more than a week to leave your body altogether.

We must also add that most drug tests won’t have a problem with CBD in your system. Since it doesn’t cause you to be impaired at work, most employers don’t set out to test for the substance. However, if your CBD product has a higher level of THC, it may lead to a positive result. Even with poorly manufactured or improperly-labeled products, this can happen. This is why you should always stick to reputed brands and third-party tested CBD products.

How Long Does a Bottle of CBD Oil Last?

This depends on how many mg (milligrams) of CBD oil a person is taking each day and the strength and concentration of the product someone is using.

If you are taking a 10mg daily dose (which is the minimum amount normally found in capsules and CBD edibles), then a 200 mg tincture of CBD will last approximately 20 days, and a 500 mg tincture will last for around 50 days, depending on how accurately you’re able to dose.
