Can CBD Oil Cause Headaches?

One of the most common disorders of the nervous system is a headache. The World Health Organization claims that almost half the entire adult population suffers from headaches at least once a year.

Headache can be caused by many different things and is usually treated by painkiller pills, which can do more harm than good to the human body. You probably have heard of or even experienced the side effects of pharmaceutical medications.

That is one of the many reasons why more and more people are turning to the alternative, more natural medicine like CBD oil. But there is a question: can CBD oil also cause headaches?

CBD oil and side effects - Can CBD oil cause headaches?

For thousands of years, herbs have been known as an effective cure for various diseases. However, herbal medications aren’t perfect. They also have minor side effects but, fortunately, far less compared to pharmaceuticals.

One of the most controversial and discussed herbs is definitely Cannabis Sativa and its well-known species – hemp and marijuana. They both contain cannabidiol (CBD), but hemp has a lower amount of THC, the cannabinoid that makes you” high”. Therefore, for medical purposes, CBD is usually extracted from the hemp plant, so it doesn’t have any psychoactive effects, and that’s why it is legal.

CBD can be found in different forms of edibles – tinctures, capsules, gummies and salves. All of those edibles contain CBD oil, which is known as very beneficial for human health. On the other hand, it can cause a few side effects, but can CBD oil cause headaches, as one of them?

In the following article, we will learn more about CBD oil and its benefits and side effects.

What is CBD oil?

CBD oil is a product derived from the stalks, leaves and flowers of the hemp plant. It contains a huge amount of cannabidiol and a small amount of THC (less than 0.3%).

There are two most common methods of producing CBD oil. The first one is the solvent extraction method, where the plant soaks in a solvent. When the liquid is absorbed, the solvent binds to the plant’s compounds. Then, this mixture undergoes heating to get concentrated CBD because hydrocarbons have a low boiling point compared to hemp’s compounds.

A more advanced and, also, more expensive extraction method is carbon dioxide extraction. Therefore, it’s not surprising it results in completely safe, pure, and healthy CBD concentrate.

Companies that use this method have the highest quality CBD products, and that is exactly what you get with the quality and purity of the CannazALL™ CBD product line.

The process starts with loading raw hemp into an extraction hopper, after which it goes under pressure, allowing the CO2 to reach supercritical temperatures. This pressurized product then goes through the entire extraction apparatus. The solid material (cannabidiol) is collected at the bottom of the container. Then the CO2 is again recycled through the extractor. The result is a pure amount of CBD.

Benefits of the CBD oil

CBD oil gained popularity over the past decades, thanks to its great benefits to human’s health. CBD oil is a cure for many diseases, so it became a part of healthcare for many people worldwide.

Widely known benefits of CBD oil are:

Pain relief

It’s widely known that CBD oil has great effects in managing pain.

As a part of the immune system, the human body has an endocannabinoid system, responsible for various functions such as pain. This system produces endocannabinoids – neurotransmitters that attach to cannabinoid receptors in your nervous system. By impacting endocannabinoid receptor activity, CBD helps reduce chronic pain, reducing inflammation and interacting with neurotransmitters.

Reduction of anxiety and depression

As most common mental health disorders, anxiety and depression can have devastating impacts on people’s health.

CBD oil functions as a natural and safe antidepressant. CBD can affect the brain’s receptors for serotonin, a neurotransmitter that helps to regulate mood and social behavior. Be careful to use pure CBD oil because any traces of THC can increase anxiety and result in the reversing of the desired effect.

Alleviation of cancer-related symptoms

People who suffer from cancer have to live with uncomfortable symptoms like depression, pain, and sleep deprivation.

Cancer treatment often results in chemotherapy which can cause vomiting and nausea. These symptoms could be so intense that the patient needs to take medications. However, common drugs may be addictive or too strong, so a better alternative is CBD oil.

In a recent study, patients who used CBD oil claimed that they felt the relief from pain, and it also helped reduce vomiting and nausea.

Reduction of acne

Acne is one of the common skin conditions that affect about 9% of the population.

It can be caused by several factors, including bacteria, overproduction of sebum, genetics or underlying inflammation.

CBD oil may help treat acne due to its anti-inflammatory characteristic and the ability to reduce sebum production. In addition, it targets problematic cells without drying or irritating the skin.

CBD oil is also contained in skincare products, as they become a more natural solution to maintaining healthy, young-looking skin.

Neuroprotective properties

Since CBD can affect the endocannabinoid system and the brain’s signalling systems, it can help people with neurological disorders like epilepsy and multiple sclerosis.

CBD oil can significantly reduce seizure activity in children with complex childhood epilepsy disorder. It can provide a better quality of life and sleep quality for people with Parkinson’s disease. It can also help reduce the progression of Alzheimer’s disease.

CBD oil is very helpful for brain damages and the nervous system. It helps the growth and development of new neurons. Traumatic blows, ischemia, or genetic and autoimmune disorders can result in permanent or temporary neural damage.

Lower blood pressure

People dealing with high blood pressure should take CBD oil due to its antioxidant and stress-reducing properties. High blood pressure is connected to risky health conditions like stroke, heart attack and metabolic syndrome. CBD has the ability to lower blood pressure and prevent heart-related illnesses.

These are the most common diseases and benefits that CBD oil has shown in treating them. But what about side effects?

Side effects of the CBD oil

CBD oil is considered to be a safe product, so its side effects are minor, especially compared to pharmaceutical medications. It’s not truly possible to take the fatal dose, but you probably won’t feel well if you take too much.

However, not every human has the same organism. Some people should definitely avoid using CBD oil:

1. People with liver disease should use CBD oil with caution.

2. Pregnant women or women who are breastfeeding should avoid CBD

3. People with low blood pressure or if they’re taking blood pressure medications.

4. Drivers or people who use heavy machinery, especially if they’re starting the treatment

That being said, let’s find out what side effects we may expect from CBD oil usage:

Dry mouth

The 2006 study showed that the endocannabinoid system receptors CB1 and CB2 are present in the salivary glands, and when these receptors are activated, saliva production can drop, leading to a dry mouth. It’s nothing dangerous, just drink more water.

Lower blood pressure

If some people consume too much CBD oil, their blood pressure would slightly decrease at the time when CBD enters their system. They might feel lightheaded or dizzy for a few minutes. It will pass on its own, but lying down, snack or some drink would help.

Changes in appetite/weight

CBD oil can either increase or decrease appetite, which can result in fluctuations in weight.


This is one of the common effects, but CBD oil itself does not typically cause it. Diarrhea is caused by the carrier oil used as one of the ingredients (coconut, grape seed or olive).

If you experience diarrhea, avoid consuming CBD oil on an empty stomach. You can eat some protein when taking oil to reduce how quickly your body absorbs it. If this still doesn’t help, try some other forms of CBD, such as gummies or capsules.

As you can see, these side effects are not that serious. Studies and consumers report these until today, but is there more?

What about headaches?

Can CBD oil cause headaches? Well, yes and no.

As we mentioned, CBD oil is a great cure for pain. Many consumers confirmed that CBD oil had helped them with headaches and migraines. So, wouldn’t it be contradictory if it can also cause it?

Can CBD oil cause headaches – when & why?

There is no clear evidence that CBD oil can cause headaches, but if you experience it after consumption, there can be several reasons.

Wrong dosage

When it comes to CBD oil consumption, it’s very important to take the right dose of oil. If you are a first-time user, we recommend starting slowly with small amounts.

Your body may need time to get used to CBD and you need to find out the right size of dosage for you. If you take too much at once, you can experience headache as a side effect. As time goes by, you can easily adjust your doses.

Poor-quality CBD oil

The CBD market is still fresh and unregulated, so not every CBD oil has high-quality ingredients and formulations.

Cannabis is grown and produced worldwide, so it can contain different toxins depending on how and where it was grown and how it was processed. Without safe protocols during all of these processes, it could result in contaminated or diluted CBD. Therefore, you probably can’t experience any benefits from those CBD oils.

High-quality products are made with mostly natural ingredients and are tested by a third-party lab. It’s always wise to buy only from the brands that have a certain reputation on the market.

Solvents and chemicals in CBD oil

CBD oil can contain solvents, such as ethanol and isopropanol or chemicals such as mercury or lead. It can impact your health causing headaches or respiratory diseases.


If CBD oil caused you a headache, it’s also possible that you experienced a Herxheimer reaction. This reaction can happen due to detoxification caused by CBD. So, the death of the cells gives you a headache as the body processes all these toxins, which usually lasts from one to three days.

Now that you know why CBD oil may cause you headaches, make sure you’re purchasing a high-quality product and follow the instructions.

To summarize

Now you have full knowledge about CBD oil and its great beneficial impacts on health and few minor side effects that may or may not happen. If you are looking for a more natural cure, then this is the perfect product for you.

However, be very careful when buying CBD oil since there are plenty of brands on the market. Get every information about the product and the brand you are buying from, so you can be sure that it is a high-quality product.

Before consumption, you should consult with your doctor if this is the best option for you. If you start with CBD oil treatment, begin with small doses until you reach the desired effect.
