How Long for CBD Oil to Take Effect after a Dose?

how does cbd work

First, it’s essential to know that your experience will vary based on your biology and the product you’re using. CBD generally “kicks in” between 15 minutes and three hours after consumption. We’ll cover the fastest ways to get CBD results in just a bit.

Next, let’s explore some of the factors contributing to each person’s unique experience with CBD.

What Affects How Long CBD Stays in Your System?

How long does CBD last in your system? This is a case where the answer is going to vary by person. Several factors affect how long CBD stays in a person’s network. The consensus-based research is that CBD stays in a person’s system for between two and five days. Some people could have CBD in their systems for weeks. That may be important to know if you’re interested in taking a full-spectrum CBD that contains traces of THC.

Here’s a look at some of the critical factors that will reduce or lengthen CBD’s lifespan in your system:

  1. Frequency of use. CBD builds in your body over time.
  2. The amount that you use. A higher dose of CBD will stay in your system for a longer time.
  3. Your body chemistry and metabolism.
  4. Body mass index (BMI).
  5. Method of consumption.

Food consumption can also impact how long CBD stays in your system. For instance, taking CBD on an empty stomach will cause the CBD to be metabolized and discharged by your body in a faster cycle.

Taking CBD on a full stomach slows the way it cycles through your system. Next, we’ll discuss how your method of consumption impacts your CBD experience.

How You Use CBD Oil Matters

Yes, the method you use to consume CBD is going to impact your experience. CBD vape products tend to offer the quickest results because the CBD is entering your lungs directly.

This method also causes the CBD to leave your body quicker than other intake methods. How long for CBD vape to work?

You can typically expect to feel the effects within a few minutes.

CBD oils and tinctures also offer quick results.

That’s because CBD oil that is applied under the tongue enters your bloodstream quickly. Unlike vape CBD products, CBD oil lingers in your system.

How long does CBD tincture take to work? It typically takes between 30 minutes and three hours for a tincture to kick in. The potency of the oil you’re using will play a role in how quickly things get moving.

CBD oil mixed into the food can take longer to kick in than CBD oil that is applied directly under your tongue. The same goes for CBD edibles.

You’ll have to wait for your digestive system to metabolize the CBD oil if you opt for the edible route.

Lastly, you can opt for what is widely considered the “slowest” delivery method for CBD. That would be creams or lotions. CBD creams and lotions absorb slowly into the skin after being applied topically. Many people enjoy these products for long-term use. However, you generally won’t feel a huge impact upon the first application.

CBD Duration Chart 

To summarize, let’s view CBD duration in the form of the table:

CBD Product Type Onset Time Duration of the Effects

CBD vape oils: 2 minutes                30 minutes to an hour

CBD oils: 30 minutes                       3 to 4 hours

CBD edibles: 60 minutes                Up to 6 hours

CBD topicals: 1-3 hours                   Up to 5 hours

Do Quality, Manufacturer, and Type of CBD Matter?

A higher degree of CBD is likely going to produce sharper, more potent results. What’s more, effectiveness and potency can vary by manufacturer. Potency can play a role in how quickly you’ll feel effects with something like a tincture. That’s why it’s crucial to measure strength in milligrams versus product volume instead of merely assuming that a higher volume means higher potency.

CBD type can also impact your experience. Generally, a full-spectrum CBD product is going to stay in your system longer than a broad-spectrum product. There is also the concern that the trace amount of THC contained in full-spectrum CBD could say in your system long enough to be detected in a blood test. Broad-spectrum CBD undergoes a process that eliminates THC.

How Long Does It Take CBD to Start Working?

The length of time it takes CBD to start working depends on many factors. They include your body weight, metabolism, and body chemistry. However, some of the biggest influences are the consumption method, the CBD potency, and the dosage amount.

CBD taken sublingually will reach the circulatory system faster than CBD is taken orally and has a higher bioavailability (more reaches the bloodstream). Also impacting the length of time to feel the effects of CBD is whether the product is made with CBD full-spectrum, CBD broad-spectrum, or CBD isolate, and the milligrams of CBD in each dosage.

Customarily speaking, you can expect to feel the effects of CBD anywhere from 15 minutes to one to two hours after consumption, depending on the CBD forms and types. This is anecdotal information provided by users.

When do CBD Gummies Start Working?

Any CBD product taken orally must travel through the digestive system first, where cannabinoids are incorporated into the bloodstream. The cannabinoids then travel to the liver, where they are metabolized and reenter the bloodstream. After arriving at the brain, the results are experienced. It can take from 30 to 60 minutes for an edible to begin working, per a study published on the National Institutes of Health website titled, “Smoking, Vaping, Eating: Is Legalization Impacting the Way People Use Cannabis?”.

The higher the potency, the quicker you should experience results. Other factors to consider include dosage amount, body weight, metabolism, and whether you eat the gummy on an empty stomach. Also important is the quality of the CBD product. It can take up to six hours for total consumption.

How Does CBD Oil Work for Relief?

CBD users have provided a lot of anecdotal evidence that CBD may help alleviate pain and calms feelings of the stress that frequently accompanies chronic pain. Each person is different in terms of the cause of the pain and their physical makeup.

Nevertheless, the way CBD oil is consumed has a meaningful impact on how long it takes the oil to work for pain. CBD oil placed under the tongue will work the fastest because it is absorbed almost directly into the circulatory system. CBD oil consumed by swallowing or adding to foods and drinks must be processed through the digestive system and liver before the effects are felt.

Like edibles, it can take 30 to 60 minutes for CBD oil to beginning working on general pain when swallowed. It can take six to eight hours before the full effects are experienced.

How Long does it Take for CBD Vapes to Work?

As pharmaceutical researchers note in an article posted on the National Institutes of Health website, the effects of CBD inhalation are affected by factors like vaporizer warmth, how great someone holds their breath, and the condition of the respiratory tract. The first results can begin in as little as a few minutes due to high systemic bioavailability.

When Does Sublingual CBD Oil Start to Work?

Sublingual CBD oil is a tincture is placed under the tongue for faster absorption. The CBD oil is absorbed through the mucous membranes located directly under the tongue and quickly enters the bloodstream.

CBD tinctures made with alcohol solutions are stronger than CBD tinctures made with a solvent of vinegar, glycerin, or oil. Sublingual CBD oil can begin working in as little as 15 to 30 minutes because it has a short route to the brain.


How swiftly does CBD oil work? The bottom line is that you can feel an impact within minutes using a direct approach like vaping or sublingual oil. Edibles or tincture oils mixed with food create more of a “trickle” effect. Nobody can say for sure how long any form of CBD will stay in a person’s system. Most data points to a window of two to five days. However, CBD can be present in your system for weeks.
