CBD Effects: How Long Do They Last?

Since the full federal legalization of hemp production under the Farm Bill in 2018, CBD usage in the U.S. has skyrocketed and the market has responded. This boom in demand has not only encouraged many new and innovative CBD health and wellness products onto the market but it’s also assisted researchers in obtaining extensive data on CBD usage.

One of the most critical elements when considering a CBD regimen is frequency and dosage. The good news is that according to the World Health Organization (WHO), CBD is extraordinarily difficult, if even impossible, to abuse. The WHO report found, “In humans, CBD exhibits no effects indicative of any abuse or dependence potential.” But the question for most people remains, how long do the effects of CBD last?

An Overview of CBD

CBD is a naturally occurring chemical found in both the hemp and marijuana plants. Because cannabidiol (CBD) is more plentiful in hemp, most CBD oil manufacturers prefer it to marijuana for cost-effectiveness and to avoid the stricter regulations that affect cannabis farming and cultivation. 

CBD does not occur naturally in human beings — although other chemicals of the cannabinoid class do — ingesting CBD does have multiple beneficial effects. CBD can:

  • Relieve pain
  • Reduce anxiety and stress
  • Improve sleep
  • Alleviate cancer-related symptoms
  • Reduce inflammation
  • Improve appetite
  • Mitigate seizures
  • Elevate mood 

Not everything is known about CBD, but researchers have determined that CBD helps with the body’s production of tryptophan, the building block of serotonin. CBD doesn’t make or help produce extra serotonin. It would be more accurate to say that CBD helps remove the obstacles of tryptophan production, which allows the body to produce as much serotonin as it requires. This essential neurotransmitter can be beneficial in reducing stress and anxiety, which leads to many secondary benefits, like improved sleep, increased appetite, and an overall sense of wellbeing. 

Factors That Affect CBD Absorption

CBD can be ingested orally via a few different delivery methods, like oils or softgels, inhaled as a smoke, or applied topically as a cream or gel. The delivery method is one of the primary factors in absorption. Below are some of the other components of CBD absorption:


Your body’s metabolism may be the most significant factor in both the absorption and duration of your CBD dosage. If you have a high metabolism, you will break down the CBD delivery method and rapidly deliver it throughout your body. This also means that with all other things being equal, a dosage of CBD won’t last as long as it would in an individual with a slower metabolism. In contrast, if you have a slower metabolism, it will take longer for CBD to kick in, but it will also last longer. 


It stands to reason that the dosage of CBD will affect the duration and absorption of CBD. Your body will take longer to metabolize a 75mg dose than it would for a 25mg dose. 

Competing Foods

If you have a full stomach, your body is digesting food and metabolizing the nutrients. These competing calories will slow down your absorption of CBD.

Sublingual Ingestion

CBD oils can be applied directly under the tongue to avoid having to be digested by the stomach. Using this method, CBD can directly enter your bloodstream and will begin working faster. 

CBD Delivery Methods

As was previously mentioned, there are multiple methods for ingesting CBD, and there are numerous CBD-infused products on the U.S. market. Here are some of the most common CBD delivery methods available:

CBD Oils

CBD oil is extracted from the hemp plant and purified by removing the non-CBD portions from the plant’s natural excretions: the oil. It is also the base ingredient for many of the other methods of ingestion or absorption. The preferred way to consume CBD oil is sublingually (under the tongue). This method allows the CBD to bypass your stomach and pass directly into your bloodstream. If you are using CBD for pain relief or alleviating migraines, this may be the best way to introduce the chemical to your body. 

CBD Softgels

These are soft “gummy” tablets that you can chew or swallow. The stomach breaks down the softgel and distributes it throughout your body. The absorption will be slower than with CBD oils. 

CBD Creams, Gels, and Lotions

Because CBD works as a natural anti-inflammatory, there are many topical applications available on the market. While a small amount of CBD will still enter your bloodstream, most of the effective chemicals will do their work at the point of application. 

CBD Vape or Smokeable Products

CBD is the second most prevalent cannabinoid in marijuana, so smoking is an obvious method of ingestion. In fact, prior to the legalization and popularization of CBD, smoking accounted for most of the consumption of CBD. There may, however, be adverse consequences to smoking or vaping CBD oils. Research is ongoing. 

Frequently Asked Questions about CBD

With CBD being a relatively new product in this market, many consumers and potential consumers have questions about the benefits of CBD. Here are some of the most common questions we receive. 

What are the types of CBD?

There are three basic types of CBD:

  • CBD Isolate – This is pure CBD. To manufacture CBD isolate, the oil has to go through additional processes to filter out any non-CBD components. CBD isolate is expensive to manufacture and more difficult to procure. 
  • Broad-Spectrum CBD – This type of CBD is usually derived from high-yielding hemp plants. It will contain terpenes and flavonoids. This form of CBD is less expensive than CBD isolate, and it should not make you fail a THC test since only trace amounts of that compound exist.
  • Full-Spectrum CBD – Many consumers are seeking “the entourage effect,” which is achieved when different naturally occurring chemicals — in this case, CBD, flavonoids, terpenes, and a small amount of THC — work together. By law, full-spectrum CBD can’t have more than .3% THC. Although this is a small percentage of the product, you can still fail a drug test. 

How Does CBD Affect the Body?

CBD has several effects on the human body. It mitigates the adverse effects of cytokine, which is created by stress. Additionally, it’s an anti-inflammatory, which means that it’s effective with regard to pain and swelling. CBD can also improve sleep and appetite. 

How Long Do CBD Effects Last?

The answer to this depends on too many other factors: metabolism, dosage, method of absorption, and what you’ve had to eat or drink prior to consuming it. With a normal dosage, the effects usually only last a few hours. Many consumers will space three doses throughout the day. People who are using it as a sleep supplement will take a single dosage before they go to sleep. It’s always best to consult your physician about dosage and times of usage.
