How Long Does It Take For CBD Oil To Work? How Long Does It Last?

How fast does CBD oil work? How long before CBD oil works? I often hear these questions especially to those who are new to CBD or those considering to take this.

If you are asking yourself the same queries, then you are just on the right page.

I’ll provide the answers you need and explain it in detail in the next sections. So, without further ado, let’s get started!

How Long Does CBD Oil Take To Work

CBD works, but the time it takes to deliver results may differ per individual depending on various factors. According to Brooke Alpert, RD, the founder of Daily Habit, a line of CBD powder, CBD isn’t a one-size-fits-all thing.

You have to consider the amount you take, the form of CBD you take and where you got your CBD as all of these things have an impact on how long it takes for CBD to work.

For instance, if you are putting a CBD product in a coffee with almond milk or sugar or anything that might need to be digested, then CBD will kick in more slowly compared to taking it sublingually.

Charlotte’s Web co-founder Jesse Stanley also shared that the strength of the CBD product may matter. “You might need to try a few strengths until you find what works for you,” he said.

He encourages the people to view CBD as a dietary supplement and give it enough time probably four to six weeks to fully realize its benefits especially if one is taking it to alleviate anxiety, pain or for stress relief.

“We are all unique in our needs and bodily systems. Some people experience rapid and very noticeable benefits while others notice benefits over time and daily use, which is common for many dietary supplements,” Stanley says.

Factors that Affect CBD Absorption and How Long CBD Works

There is no universally accepted or daily recommended dosage for CBD. This is also true when it comes to how fast or slow CBD works. Here are some factors that determine the effectiveness and how fast CBD works.

Origin of the hemp – Alpert and Stanley both recommend that you get a full-spectrum CBD product because it contains all the cannabinoids that are found in the cannabis plant. Full-spectrum CBD is more effective than CBD isolate and tends to deliver faster results.

Method of consumption – The way CBD is administered has a huge impact on its bioavailability. In theory, intravenous or IV administration is a direct way to get the most CBD absorbed into the bloodstream, but that is neither comfortable or the most preferred option.

CBD comes in many forms, there are gummies, oils, tinctures, capsules, and powders. You can take CBD sublingually, topically, orally or by inhaling it.

However, edibles take a longer time to reach the ECS, but they also stay in your system longer, so you experience the benefits for an extended time. Meanwhile, taking CBD orally takes between an hour to 6 hours for its levels in the bloodstream to the peak which makes oral consumption the perfection option for individuals looking for long-term therapeutic effects or supplementation.

Body Weight – The amount of body fat determines the amount of CBD you have to take. Heavier people are recommended to take more dosage. Remember, you need to take enough CBD to see results. Your body weight and mass also affect how long the CBD remains in your system.

People who weigh more tend to have more fat cells enabling them to absorb and store more CBD. Thus, heavier people with more fat experience prolonged effects of CBD. Meanwhile, those who weigh 150-240 pounds should take a dose of 15-20mg twice daily to get the most effects.

Metabolism – The metabolic rate also influences how long CBD stays in the system as it determines how long it takes to break down and synthesize compounds, which will affect how long it takes the body to process and metabolize the cannabinoid.

Frequency of use – Aside from the human body, the frequency of usage also matters. Some take it in the morning, others at night. Several also consume CBD twice. How often you take CBD might depend largely on the type of product, amount of CBD present and the ailment you are targeting.

You do not have to worry about this because reputable manufacturers usually provide instructions on how to properly utilize their products. This has likely to do with the dosage you need to take.

Dosage and Potency – The higher the dosage of CBD, the higher the amount that will eventually be absorbed in the body. This is also true for the concentration, potency or purity of the CBD product.

QualityCBD oil products are not created equal. They have different formulations, some have impurities, additives and carrier oils like hemp seed oil, coconut oil, terpenes and more. Anything added on the production will in one or more ways affect how CBD will be absorbed, processed and metabolized the body.

How Long Does It Take For CBD Oil To Work For Anxiety

CBD oils have been proven effective in alleviating anxiety and depression systems. CBD works well for obsessive-compulsive disorders, panic disorders, phobias, mild depression, general anxiety disorders, post-traumatic stress disorders, and agoraphobia.

A general rule of thumb is to take a few drops of CBD oil and see how you feel. If you don’t see any positive effects after a few weeks, increase the dosage.

However, each person is different, so the results may vary. Some users experience improvements in their anxiety and depression after just a few hours of taking CBD oil. Meanwhile, others have to wait a few days. Some also experience improvements after 2 weeks.

It’s best if you monitor your CBD oil intake and keep a journal to determine the best dosage for you. If you don’t see any result, increase the dosage. In general, give it a few weeks to see results.

How Long Does It Take For CBD Oil To Work For Pain

CBD works with common aches and pains. They can also help with inflammation that comes with muscle soreness and restless legs.

This is also beneficial for arthritis, fibromyalgia and joint pain. A 2016 study revealed that CBD gels on rats reduced both joint pain and inflammation without any side effects.

How fast does CBD oil work for pain? As mentioned above, the effectiveness of CBD differs depending on the factors that affect the absorption of CBD.

The form of CBD and the intensity of pain you are experiencing are among the factors that you have to consider when determining your CBD dosage. Your body weight and the quality of the CBD product also matters.

I can’t give a concrete turnaround time when CBD works for pain as this depends per individual. However, one thing is sure, it works.

CBD oil for pain management is cost-effective and convenient because you can easily control your dosage and the effects last for about 2 to 6 hours.

How Long Does CBD Work For Sleep?

Do you have insomnia or other sleeping problems that keep you from enjoying a good night’s rest? Do you wake up feeling tired and restless every morning? If you do, CBD might help you with that.

It doesn’t really take long for CBD to work when it comes to help you sleep. According to Healthline, you can take CBD at least an hour before bed to improve insomnia and promote a restful night’s sleep.

The speed CBD takes to work for sleep also depends on the way you take it. Vaping CBD like BEBOE’s Calming CBD Blend is short-acting because it takes as little as 90 seconds to work, but only last for about an hour.

Taking a CBD tincture sublingually to help you sleep takes 20 minutes to kick in and the results last between four to five hours. If you opt for edibles like CBD pills or CBD capsules, it will take up to two hours to work and the results may last between six and eight hours.

How Long Does CBD Take To Work For Nausea

CBD has been proven to be very effective in reducing nausea and vomiting for patients who underwent chemotherapy.

A 2014 article published in the European Journal of Pharmacology reported that “cannabis has long been known to limit or prevent nausea and vomiting from a variety of causes.”

How long does it take for CBD to take effect? According to a study published in the British Journal of Pharmacology, the participants were given cannabis-based medicines two hours before the start of each cancer treatment and every six hours thereafter for 24 hours.

After a total of 480 treatments, the only side effects reported were slight irritability in two of the youngest children between 3.5 and 4 years old. Both acute delayed nausea and vomiting were controlled.

If you are experiencing these conditions, take CBD and wait for a couple of hours. You will likely experience an improvement after two hours or so.

How Long Does It Take For CBD Oil To Work For Epilepsy

CBD works well for epilepsy or seizures. Galveston resident Trysten Pearson experienced his first seizures in 2013 when he was only 12. His life changed when he was 17 and tried CBD.

“I really wanted this medicine to work because of how many times pills have failed me,” said Trysten, who takes drops of the oil orally. “Once I started taking it, I felt so much better. I don’t have seizures,” Pearson said.

CBD works immediately for epilepsy, but this might work differently per patient. For Pearson’s case, in the first 30 days using CBD, he only experienced one seizure.

CBD oil works for IBS, ulcerative colitis and Chro’s disease too. It even works for cats and dogs if your pets have health issues.

However, it works differently per individual because it delivers results based on one’s weight, CBD dosage, CBD quality, frequency of use and metabolism to name a few. The way your body responds to the medication also matters and it makes a huge difference.

If you know someone who is also taking CBD and it works immediately for her but not you, don’t be sad and just continue taking it, maybe it just takes longer for you. Give CBD enough time, keep using it for at least six weeks.

How Long Does CBD Last?

How long does CBD oil last?

Just like the way it takes for CBD to work, the span of time it works depends on various factors including the CBD form, how you take it, its quality and the dosage to name a few.

Usually, CBD effects last for approximately 4 to 6 hours, but then again, the results may be shorter or longer depending on the strength of the dose.

CBD edibles, capsules, tinctures, vaporizers and topical creams have different duration.

Here’s an overview of the CBD duration.

CBD Oil FormatOnset of EffectsDuration of effects
CBD vape oils (inhalants, vape juice, e-liquid, CBD flower)They work within minutes as these products bypass the digestive process and are absorbed directly into the lungs.30mins to 1hr
CBD gummies, ediblesUp to 60 minutes. Edibles must pass through the digestive system before being absorbed through the liver. 4hrs - 6hrs
CBD oil, tinctures or dropsUp to 30 minutes. Drops and tinctures bypass the digestive system and CBD is absorbed Up to 30 minutes. Drops and tinctures bypass the digestive system and CBD is absorbed directly into the bloodstream through the skin under the tongue.2hrs - 4hrs
CBD Oil CapsulesUp to 60 minutes – CBD capsules must pass through the digestive system before being absorbed4hrs to 6hrs
CBD Oil TopicalsUp to 2 hours. Topicals must be absorbed through the skin. The CBD’s absorption rate can be impacted by the amount of hair on the skin and fatty tissue under it.2hrs - 4hrs
CBD Oil Transdermal PatchesIt may take hours to show effects. The CBD’s absorption rate can be impacted by the amount of hair on the skin and fatty tissue under it. Transdermal patches may also be designed to release CBD at certain time intervals over the course of their relatively long lifetime.24hrs - 28hrs


CBD works differently per individual and the turnaround time depends on many factors like user’s weight, dosage, frequency of usage, quality of the product and more. This is true to how fast CBD works and how long it lasts. CBD oil may or may not work immediately. So, give it time, perhaps, 3 to 4 weeks or month.

Remember, there is no universal rule when it comes to how CBD delivers results. The process takes a trial and error. You’ve got to work on it to determine the best dosage and the frequency of usage that will work best for you considering your ailment, metabolism, and body weight.
