Can CBD Cause Headaches

Chronic headaches are one of the most common medical complaints, with an estimated 10-15% of adults experiencing frequent episodes at least once a month. While there isn’t yet definitive evidence on how CBD affects headaches and migraine pain specifically, some studies have suggested that it may help reduce inflammation associated with migraines, which suggests that it might also have the potential to be a preventative measure against future headaches. We’ll look at all of this information and more to determine if CBD is causing headaches.

Overview Of Cannabidiol

Cannabidiol, more commonly known as CBD, is like a hidden key that unlocks the potential of hemp and cannabis plants. CBD extraction from these plants provides many beneficial health effects without any of the psychoactive effects typically associated with medical marijuana or other cannabinoids like THC. In recent years, medical cannabis has become increasingly popular for treating various health conditions, including migraine headaches. The question arises– does using CBD oil cause headaches?

The short answer to this question is not necessary. While there are some adverse side effects of taking CBD, such as fatigue, changes in appetite, and weight gain, studies suggest that it does not directly contribute to migraines or other types of headaches. Because every individual human body reacts differently to prescription medications and supplements, it is possible that someone could experience headaches while taking hemp-derived CBD. If a person experiences any uncomfortable symptoms while taking CBD, they should stop using it immediately and consult their doctor before continuing use.

Research indicates that the effectiveness of CBD oil depends on the dose taken and how often it is used. Start small; begin by trying out lower doses first and gradually increasing until you find your ideal dosage level that works best for your body’s needs. It is also important to remember to purchase only high-quality hemp-derived CBD products from trustworthy companies so you know exactly what you’re consuming.

Potential CBD Side Effects

While many CBD users experience a range of health benefits, it’s important to note that there may also be negative side effects associated with its use, like headaches or migraines.

Headaches associated with CBD usage appear to be linked to dosage and product type. Most commonly, these episodes are associated with the ingestion of oil products containing high THC and CBD concentrations. In addition, those who take larger doses than what their medical professional recommends seem more likely to experience this side effect.

It’s important for people who experience headaches to understand the risks when taking any supplement, including high-quality CBD-based products. Those who suffer from regular headaches should consider speaking with their doctor before using CBD or any other herbal medicine in order to determine if it could potentially cause an adverse reaction.

Reasons For Headaches Caused By CBD

The potential side effects of CBD have been widely discussed. While some people have reported experiencing minor headaches from taking CBD, the evidence is inconclusive as to whether it can actually cause headaches in all cases. It is important for individuals interested in using CBD products to understand what could potentially lead to such a common side effect and how they may be able to prevent it.

Reports suggest that headache symptoms usually occur when people take too much CBD or ingest low-quality products with minimal regulatory oversight. High doses can create a feeling of dizziness or lightheadedness, which can contribute to head pain similar to migraines. Additionally, certain ingredients used in manufacturing processes can also increase the risk of developing adverse reactions, including headaches.

Therefore, before beginning any kind of regimen involving CBD products, it’s important for users to consider the quality and proper dosage instructions provided by manufacturers and consult their doctor about any possible risks associated with taking them – especially if you are prone to casual headaches or other medical conditions. Taking these steps will help ensure your overall safety and well-being while reaping the full benefit of this powerful oil extracted from nature’s own resources.

Drug Interactions To Note

Incorporating CBD has the potential to interact with a variety of pharmaceutical drugs and blood thinners. It is important to note that when taken in combination, it can cause an unexpected drop in blood pressure, which could lead to adverse health outcomes for humans. If you are taking any blood pressure medication regularly, it is recommended that you speak with your doctor about possible interactions before using CBD.

It is also essential to remember that large doses of CBD may increase the risk of developing medication overuse headaches if used frequently or too close together. Therefore, it is important to follow the dosing instructions provided by your doctor or pharmacist closely and not exceed the prescribed amount without consulting your physician first.

Finally, as with many supplements, the wrong dosage or frequency can result in side effects, so caution should be exercised when considering how much CBD to take and how often. 

Potential To Reduce Migraines

Migraine headaches can be a debilitating condition. Understanding how CBD might have an effect on migraine attacks is essential to determining its potential therapeutic benefits.

The use of quality CBD products may potentially reduce the frequency and intensity of migraine attacks for some users, although more research is needed to determine the exact mechanism at play. While there are no adverse effects that have been linked to using CBD, it’s important to consult your healthcare professional before beginning any treatment plan.

To further understand how CBD could benefit those who suffer from chronic migraines or tension headaches, here are three key points:

  1. Research indicates that cannabinoids interact with endocannabinoid receptors in the brain, which helps regulate chronic pain levels associated with headache disorders.
  2. Studies suggest that cannabidiol (CBD) may improve sleep quality, providing relief from rebound headaches due to a lack of restful sleep cycles.
  3. There is evidence that topical applications of CBD-rich hemp plant oil can provide localized relief from pain due to muscle tension and other causes of stress-related types of headaches.

At this time, we don’t yet know whether these findings will hold true when tested in larger clinical trials, but they indicate promise for those living with migraine-related symptoms and conditions.

Taking Incorrect Doses Of CBD Oil

According to a lab report from third-party testing, an incorrect dosage of CBD oil can be linked to headaches in some users. In fact, approximately 28% of first-time users reported feeling a headache after taking the wrong dosage. This is likely due to the decrease in blood pressure that results from using it.

The risks associated with taking an incorrect dose are not limited to just headaches; they can also lead to fatigue and confusion, as well as increased levels of stress. For those who use CBD for therapeutic purposes, these side effects should be taken into consideration when determining the right amount for their body.

It is important to note that while there are potential risks associated with taking too much or too little CBD oil, that does not mean that every user will experience them. It is always best practice to start small and gradually increase your dosage until you find what works best for you.

Poor Quality CBD Oil

The use of low-quality CBD products can lead to unwanted side effects, including aching headaches. Poor-quality hemp oil is not suitable for treating headaches and should be avoided.

The concentration of the active ingredients in low-quality CBD oil may vary wildly from batch to batch, leading to unpredictable results when using it as a therapy for migraine relief. Additionally, contaminants such as heavy metals, toxic chemicals, or pesticides could be present in CBD products due to inadequate safety and testing standards for these types of products.

This lack of consistency and quality assurance that what you are ingesting is safe and effective means that anyone considering taking CBD as a remedy for headaches must do so with caution, ensuring they source only organic, high-quality CBD products free from microbial contamination or filler ingredients.

It’s important to understand the potential risks associated with taking any form of supplement, particularly something new like CBD, which has yet to have long-term studies conducted on its effectiveness and safety profile. Always consult your doctor before starting a new course of treatment if you experience regular headache symptoms or other health conditions related to them.


In conclusion, CBD has been known as a natural remedy that has been used to treat various ailments. While it may be beneficial for some people, there are potential undesirable side effects, such as tension headaches. These can occur due to drug interactions, the wrong dose, or low-quality CBD. It’s important to discuss any treatment plan with your doctor before starting so they can properly assess if CBD is right for you and guide you on the correct dose needed.
