Does CBD Cause Headache? Understand Risks and Benefits

Cannabis plants, whether hemp or marijuana, have been in the limelight in recent years due to their myriad potential uses, especially for medical purposes. Among these, CBD oil, derived from these plants, is a star. However, some people ask, "Can CBD oil cause headaches?" It's a legitimate question since the CBD industry is booming with various products like CBD gummies and CBD edibles that promise health benefits. This blog delves into this issue, examining whether CBD use can lead to headache symptoms or provide an effective treatment for chronic headaches and migraines.

Does CBD Cause or Relieve Headaches?

The conversation around CBD oil and headaches is a bit of a mixed bag. Essentially, we're dealing with two contrasting narratives here, much like the chicken and the egg conundrum. On one side, we have folks who swear by CBD as their go-to solution for chronic pain, including stubborn tension headaches and crippling chronic migraines. They find that CBD products, like CBD oil and CBD gummies, offer them much-needed relief. This seems plausible considering CBD’s interaction with the endocannabinoid system, which plays a role in managing pain and inflammation within the human body.

On the flip side, though, we've got a small cohort of CBD users who, strangely enough, experience headaches after using CBD. These anecdotal reports are puzzling and contrary to the general trend of CBD being used for pain relief.

The "why" behind this paradoxical effect isn't entirely clear yet. It could be due to several factors:

  • Different effects in different individuals: Just as with prescription medications, CBD might not have the same effect on everyone. Each individual’s endocannabinoid system may respond to CBD in a unique way.

  • Unwanted side effects: Sometimes, the headaches might not be directly from the CBD but from the potential side effects of CBD use, such as dry mouth or lower blood pressure. For instance, low blood pressure could potentially lead to lightheadedness and headaches.

  • Low-quality or contaminated CBD products: Not all CBD products on the market meet high-quality standards. Some products could contain heavy metals, toxic chemicals, or not have the correct amount of CBD as advertised. These factors could potentially contribute to headaches.

  • Incorrect dosage: Taking too much CBD, especially high doses of CBD oil, could lead to unwanted side effects, including headaches. It's often recommended to start with small doses and gradually increase as needed.

Regardless of the ongoing debate, one thing is clear - there's a need for more scientific research and clinical trials to fully understand CBD's potential benefits and adverse reactions, especially when it comes to CBD and headaches.

Key Takeaway: The relationship between CBD and headaches is complex and varies from person to person. While CBD may provide relief for some individuals dealing with chronic headaches and migraines, others might experience headaches as a potential side effect of CBD use. The quality of the product and the dosage are crucial factors that could influence these outcomes. More scientific research is needed to fully understand this relationship.

The Role of the Endocannabinoid System in CBD Use

Let's get into some nitty-gritty about the role of the endocannabinoid system in CBD use. Just to give you a heads up, this might feel a bit like a biology class. But don't worry! We'll try to make it as fun and interesting as possible.

So, what is this endocannabinoid system everyone in the CBD industry keeps talking about? Simply put, it's a complex cell-signaling system in the human body. It was discovered in the 1990s when scientists were studying THC, another compound found in cannabis plants. Although much of its functions are still a mystery, it's known to play a role in regulating a range of functions and processes in our bodies, including sleep, mood, appetite, and, you guessed it, pain!

Here's how the endocannabinoid system is involved when you use CBD:

  • The cast of characters: The endocannabinoid system is composed of endocannabinoids (which are naturally produced in your body), receptors that these endocannabinoids bind to, and enzymes that help break down endocannabinoids.

  • CBD's interaction: Now, here's where it gets interesting. Unlike THC, which binds directly to one of the major endocannabinoid receptors (CB1), CBD doesn't bind directly to either the CB1 or CB2 receptors. Instead, it seems to help endocannabinoids in your body perform more effectively.

  • Impact on pain and inflammation: This interaction is thought to have a positive impact on the body's pain and inflammation responses. This is why some people find CBD products helpful in managing chronic pain or conditions like arthritis.

  • Possible adverse effects: But just as with any other substance, there could be potential side effects. Some people might experience dry mouth, lower blood pressure, or even headaches. It's crucial to understand that everyone's endocannabinoid system is unique, so CBD's effects can vary from person to person.

And there you have it - a snapshot of the endocannabinoid system and its role in CBD use.

Key Takeaway: The endocannabinoid system is a crucial component in how our bodies respond to CBD. It helps regulate various physiological processes, including pain sensation, which is why CBD might help some individuals manage chronic pain. However, CBD's effects can vary widely, and potential side effects can occur, underlining the importance of consulting with medical professionals when considering CBD use.

The Importance of High-Quality CBD Products

In the buzzing world of CBD, there's a dizzying array of products to choose from - CBD oils, CBD gummies, CBD edibles, and so on. However, not all that glitters is gold, and the same applies to the CBD market. While some companies are committed to offering high-quality CBD products, others might be selling low-quality or even potentially harmful products. Hence, it's crucial to emphasize the importance of sourcing high-quality CBD products. Here's why:

  • Avoid unwanted side effects: High-quality CBD products undergo rigorous testing and quality control measures to ensure they're free of unwanted contaminants like heavy metals and toxic chemicals. On the other hand, low-quality CBD products might contain such harmful substances that can lead to adverse side effects or health risks.

  • Ensure correct CBD content: Sometimes, products on the market don't contain the amount of CBD they claim. Some might have significantly less, while others could contain more. Either scenario could lead to problems, like not experiencing the desired effects or experiencing unwanted side effects, respectively.

  • Experience the entourage effect: High-quality CBD products, especially full-spectrum ones, can offer what's known as the 'entourage effect.' This is where the various cannabinoids and terpenes in the product work synergistically to enhance the potential benefits of CBD. Low-quality products may not offer this.

  • Get value for money: Let's face it - CBD products aren't exactly cheap. So, if you're going to spend your hard-earned cash on them, you want to ensure that you're getting a product that's effective and safe.

Remember, when it comes to CBD products, it's not a case of 'you get what you pay for.' Some products might be expensive but of poor quality, and vice versa. It's always a good idea to do your research, check for third-party lab test results, and opt for products from reputable sources, like the ARCannabisClinic.

Key Takeaway: High-quality CBD products are essential for ensuring safety and efficacy. Low-quality CBD products can contain harmful contaminants and incorrect CBD content, leading to potential health risks or ineffective treatment. Always research and select products from reputable sources to get the most out of your CBD experience.

Understanding Potential Side Effects of CBD Use

As we delve deeper into the world of CBD, let's touch on a topic that some folks might feel a bit uneasy about - the potential side effects of CBD use. As much as we love to talk about the benefits of CBD for conditions like chronic pain and anxiety disorders, it's equally important to address the flip side of the coin.

Like any substance we consume, CBD can produce side effects, particularly if consumed in high doses or used improperly. However, the World Health Organization has noted that CBD is generally well-tolerated and has a good safety profile.

Here are some of the potential side effects of CBD use:

  • Dry mouth: This is one of the common side effects reported by CBD oil users. It's not too severe and usually resolves on its own after a while.

  • Lower blood pressure: High doses of CBD oil can cause a small drop in blood pressure, usually within a few minutes of the CBD entering your system. While this isn't a problem for most people, it could be an issue for those with already low blood pressure.

  • Drowsiness: For some folks, CBD can cause feelings of drowsiness or fatigue. It's important to monitor how you feel and adjust your dosage accordingly.

  • Changes in appetite or weight: Some people might notice appetite changes or weight gain when using CBD. Remember, each person's reaction to CBD can be different, so this doesn't happen to everyone.

  • Interaction with other medications: CBD can interact with certain prescription medications, altering how your body processes them. If you're taking any medication, especially blood thinners, it's crucial to talk to your doctor before trying CBD.

It's also important to note that the risk of side effects may be greater with low-quality CBD products. These products can contain unwanted substances like heavy metals and other contaminants that can lead to negative side effects.

Key Takeaway: While CBD is generally considered safe and well-tolerated, potential side effects can occur, particularly with high doses or if CBD is used improperly. These side effects may include dry mouth, lower blood pressure, drowsiness, changes in appetite, weight gain, and interactions with other medications. Always consult with a healthcare professional before beginning any new treatment regimen.


  1. Can CBD cause unwanted side effects? The short answer is, yes, CBD can lead to unwanted side effects. It can potentially interact with prescription medications, such as blood thinners, leading to adverse reactions. However, these side effects typically occur at higher doses.

  2. What are some common side effects of CBD oil? The most common side effects of CBD oil can include dry mouth, weight gain, and lower blood pressure. Other potential side effects could be related to the quality of the CBD product used. For instance, low-quality CBD products might contain heavy metals or toxic chemicals, which could result in adverse side effects.

  3. Does CBD cause headaches? Reports about CBD causing headaches are mixed. Some individual reports suggest CBD oil use leads to headaches, while others find CBD offers effective relief from chronic migraines and tension headaches. More scientific research is needed to draw definitive conclusions.

  4. How much CBD should I take? The correct dosage of CBD can vary significantly depending on the health condition being treated, the form of CBD being used, and individual body chemistry. It's generally recommended to start with lower doses and gradually increase as needed.


While CBD oil, a product of cannabis and hemp plants, has shown promise for conditions like chronic pain and anxiety disorders, it's crucial to understand its potential side effects. Anecdotal reports and some scientific evidence suggest CBD may cause headaches in some people, but it may also provide relief for others.
