Does CBD Cause Headaches?

Does CBD Cause Headaches?

CBD, also known as Cannabidiol or Cannabinoid, has increased in popularity in recent years as an all-natural, go-to home remedy.

The CBD industry has jumped into creating CBD-infused items such as bath salts, coffee, lotions, oils, pet treats, shampoos, and more.

It's not surprising that an increasing number of consumers want to test CBD products and get the reported benefits.

There’s no doubt CBD provides many health benefits but just like other drugs and medications, CBD comes up with a few undesired side effects like fluctuation in blood pressure, drowsiness and headaches.

While we've previously addressed certain questions regarding CBD, we're here to tackle another major and debated concern: Does CBD oil actually cause headaches?

We'll look at why and how CBD oil could cause headaches, as well as the causes for each type of headache CBD oil might cause, and much more.

Let's take a closer look.

What is CBD?

CBD is the first and most abundant Cannabinoid found in hemp. When hemp was legalized and approved by the FDA, CBD products exploded into the mainstream.

CBD is a non-addictive and non-psychoactive compound and is considered a safer and more reliable drug than THC (Delta-9-tetrahydrocannabinol).

Cannabidiol interacts with our endocannabinoid system (ECS) and helps to regulate appetite, immune system, sensory processing and sleeping cycle.

Furthermore, CBD has been shown to have neuroprotective and anti-inflammatory properties that help in the maintenance of the body's homeostasis.

Cannabidiol Health Benefits

CBD oil provides a wide range of health benefits, including:

  •         Controlling PTSD
  •         Reducing sleeplessness and anxiety
  •         Pain relief for arthritis
  •         Improving sleep quality
  •         Improving skin issues like acne
  •         Lowering the desire for nicotine and drugs
  •         Reducing pain and inflammation
  •         Preventing seizure

There is no doubt that there is ongoing research and clinical trials on CBD to see how effectively it cures illness and how beneficial it can be.

Why Does CBD Have Risks and Side Effects?

We all know all medications provide health benefits but it doesn’t mean they can’t have any adverse side effects, there can be both positive and negative effects of any drug.

Just like other consumable substances, Cannabidiol can impact consumers differently.

CBD can cause nausea, diarrhea, dizziness, dry mouth, and sudden drop in blood pressure means that consumers must be aware of the CBD dosage and amount of CBD they take in at a given time.

The effects of CBD on ECS can vary greatly, it depends on the dosage.

Despite the fact that no studies have found any proof of it to date, some people state that CBD oil actually caused headaches. This triggered a huge debate about whether CBD really causes headaches.

Does CBD Cause Headaches?

It's likely that you've consumed a CBD product of low quality that contains chemicals and solvents if you're getting headaches or migraines as a side effect. Because the CBD market is yet unregulated, several manufacturers neglect product quality in order to reduce costs.

And it's possible that these filler substances are causing your headaches. As a result, it is important to educate yourself on high-quality CBD products and purchase them from reputable or authorized dealers.

Another cause of headaches could be the amount of medication you're taking. While there isn't any clear research on the best CBD oil dosage just yet, ingesting too much of it at one time might be harmful, especially if you're new to it. It is better, to begin with, a lower dose and allow your body to adjust to the CBD oil before increasing the dose size which will help you attain the desired benefits.

To be clear, there is still no evidence that CBD oils cause headaches in consumers. To reduce the risk of experiencing head pain from these medications, it's best to start with high-quality items and the minimum possible dosage.


What Does Research Say About CBD & Headaches?

The time of consuming CBD products and dosage have a lot to do with side effects. People may experience side effects like migraines, lightheadedness, and dry mouth but these don’t include headaches.

So far, researchers haven’t found any evidence that CBD causes headaches.

In 2017, research has been conducted on which people consume CBD oil and experience apparent side effects. People experienced weight gain, fatigue, diarrhea, and appetite changes, but no headaches were reported.

According to a 2018 study, researchers found clear evidence that ECS plays an important role in regulating migraines. This indicates that Phytocannabinoids (cannabinoids present in cannabis) have a similar effect on the ECS.

Similarly, a study in 2016 showed that Marijuana helps in decreasing the frequency of migraine attacks. However, they concluded that additional research and tests are needed for a better understanding of the relationship between Marijuana dosage and migraines.

In the same way, there is no clear link between CBD and headaches. The only evidence found is that Cannabidiol helps to reduce headache symptoms like anxiety, depression, etc.

If you are using CBD and experiencing headaches, it is important to speak with a healthcare provider to determine the cause of your symptoms. They can help you determine whether the CBD is the cause of your headache and suggest ways to manage your symptoms. It is also important to use CBD products as directed and to only use products that have been tested for purity and quality.


Then Why Do Consumers Complain of Headaches?

We have reviewed all research and studies and found no clear evidence of CBD causing headaches.

However, the following are a few plausible causes of headaches after ingesting CBD:

1)      Wrongful Association

We normally blame the last meal or beverage we consumed for stomach aches, aren’t we? People often do the same with CBD oil.

If you’re consuming CBD oil for headaches and you experience severe headaches it’s most likely because you haven't given the cannabinoid enough time to heal you or it could be possible that you haven’t consumed the required dosage to treat your headache.

2)      Low Quality CBD Products

It’s a major cause, your CBD products may contain additional ingredients that counter the benefit of CBD. It is possible since you can get CBD at a lower cost and maybe you can buy a product that does not include any Cannabinoids at all. That’s why we always recommend you purchase only from reputable brands in the market.

Carmen’s Medicinal offers pure CBD products from oil, and gummies to capsules. Our products don’t contain any harmful ingredients, you can check our lab reports and lab tests at our official website:



3)      CBD Dosage and Timings

It can be difficult for new users to determine the proper dosage. Unfortunately, the effects of CBD differ from person to person. A small dose can make you feel energized, while a large dose can put you to sleep. We recommend keeping track of your experiences and how your body responds to each dosage. These records might help you figure out the right dosage and timings for taking CBD.

To Avoid Headaches, Consider CBD Quality & Source

Never buy CBD oil from an unauthorized source. There are many people who do not have a license to grow cannabis or make and sell CBD oil.

Consider the following factors while choosing a product:

  • CBD Source: Find out where the company grows its cannabis before purchasing a type of product (hemp/cannabis or marijuana).
  • Third-Party Lab Testing: Never purchase a CBD product that doesn't declare its authenticity through test results from an authorized laboratory. These tests confirm the product's potency, purity, and chemical contamination.
  • CBD Product Labeling: Check the CBD product's label. This tells you a lot about the brand and ingredients. Products that are not sourced properly, are of poor quality and are not safe to consume.

Many factors can contribute to headaches. Do not include contamination into CBD oil to prevent headaches.


How does CBD affect headaches?

According to a recent study, the great majority of migraine sufferers found relief through the consumption of CBD oil. According to the results of a clinically validated survey, 86% of respondents reported a reduction in headache impact after using a cannabidiol (CBD) formulation for a 30-day trial period.

Can CBD cause rebound headaches?

Researchers examined the data of 368 individuals who experienced chronic migraine for at least a year and discovered that those who used cannabis had a much higher risk of getting medication overuse headaches, or rebound headaches, than people who did not consume cannabis.

Does CBD affect your brain?

CBD has been shown in studies to affect blood circulation in the brain. People experience no anxiety after taking CBD because Cannabidiol reduces the blood flow to the part of the brain that causes anxiety.

What is CBD migraine?

Research suggests that Cannabidiol (CBD) oil may help cure migraines by reducing inflammation and relieving discomfort. The increasing number of studies indicates that CBD can help to ease pain, particularly neurological discomfort associated with a variety of diseases.


The Important Takeaway

Keep in mind that the whole CBD market is still growing. While important discoveries and possibilities have recently emerged and more scientific data and evidence are required to support CBD as a viable medical treatment. This also indicates that no one is currently aware of the ideal dosages, complete benefits, impacts, and concerns of ingesting CBD products, especially in the long term.

You should use CBD oils with caution as responsible consumers because different people may react differently to them. Always do your research on the potential consequences of the CBD oils you're utilizing. To ensure the authenticity and quality of the products, be sure to thoroughly check labels and packaging.

Additionally, before using CBD products or putting them into your regular health routine, always get the advice of your doctors or other medical specialists. It's better to know in advance that these will not interfere with any current drugs, supplements, or ailments you may be undergoing.

Remember: Simply because something originates from nature does not mean it is safe to consume. CBD and THC are examples of such substances. Do your research, find products you can trust, start low, and always consult with a medical professional.
