Why Are Headaches a Common Side Effect of CBD Oil? It is an established scientific fact that medical cannabis has multiple benefits on the human body. Cannabidiol or CBD oil is rising in Cannabis users sometimes say THC gives them headaches. Can the same thing happen with CBD flower, though, or does smoking CBD help with headaches? These days we are seeing all the seemingly miraculous benefits of cannabidiol (CBD) pile up. But what about the side effects? Read this in-depth guide to learn about side effects of CBD oil and if it can cause headaches.
Why Are Headaches a Common Side Effect of CBD Oil?
It is an established scientific fact that medical cannabis has multiple benefits on the human body. Cannabidiol or CBD oil is rising in popularity as a treatment for anxiety, chronic pain, seizures, and sleep disorders. It is being used in hospitals and homes across the globe. However, there have been anecdotes of users getting headaches when using CBD oil. Is there a scientific basis for this claim?
Can CBD Oil Cause Headaches?
Any substance that you consume has its pros and cons. Although CBD oil can help address a range of ailments and illnesses, it can trigger unwanted side effects as well. The common side effects of CBD oil discovered through scientific studies are dry mouth, changes in appetite, hypotension (low blood pressure), lightheadedness, drowsiness, and diarrhea. Thankfully, most of the recorded side effects are mild in nature.
Despite extensive research, scientists have found no evidence to support the idea that CBD oil causes headaches or related conditions like migraines. Some users may consider lightheadedness or dizziness a headache, but it is unlikely. Therefore, it is more probable that the real cause of headaches may not be CBD oil itself but factors pertaining to its production and use.
It may be helpful to remember that headaches can be caused by a myriad of factors including stress, caffeine, dehydration, and lack of sleep. Outside of the research environment, it is difficult to control the lifestyle factors of CBD oil users. Certain side effects can also be triggered due to drug interactions. For instance, antipsychotic drugs like pimozide are known to negatively interact with CBD.
Given that evidence from clinical trials show that CBD oil does not cause headaches, let us examine other possible causes.
When taking any medication or supplement, the correct dosage is important. A dosage that is too low may lead to inadequate outcomes while a dosage that is too high may cause undesirable side effects. Because CBD oil is so easy to administer, users can be prone to overdosing. Although CBD is non-toxic, excessively high doses may be responsible for causing headaches.
For first-time CBD oil users, it is recommended to start with a small dose and gradually adjust the dosage as your body gets accustomed to it. Consider consulting a medical professional with experience in CBD to figure out the optimal dose for your body weight and health condition. Your doctor can also help to monitor your body’s response over the course of treatment and modify the dosage as needed.
Poor CBD Oil Quality
Unfortunately, cannabis products can vary drastically in quality. As the CBD market is still emerging, it is not yet fully regulated. Hence, some less-reputable brands may sell CBD oil produced from inferior hemp strains or synthetic ingredients. While such products may cost less, they can lead to severe side effects including respiratory issues and allergies.
Cannabis is grown in many regions of the world. The quality of the cannabis plant relies heavily on the purity of the soil in which it was grown as well as whether the plant was treated or processed with volatile chemicals. If the cannabis plant absorbed mercury, lead, or other harmful substances, the resulting CBD oil may be contaminated with toxins.
Lack of Laboratory Testing
Given that the CBD industry is largely unregulated, consumers must look for proof of third-party testing. Independent laboratory testing results will tell you more about the quality and potency of a CBD oil product. It will also list the ingredients, including warning you of any residual solvents or contaminants that should not be present in the product.
Third-party testing results or certificates of analysis should be readily available on CBD brand websites. Never purchase CBD oil from a company that undertakes its own laboratory tests or does not disclose laboratory findings. The absence of proper labeling is a major red flag and a sign that the associated product could do more damage than good.
Aside from third-party tests, look for CBD oil that is made from natural ingredients. There should be no unnecessary solvents, oils, or fillers added to bulk up the product. Ideally, the hemp from which the CBD oil is extracted should be sustainably grown on an organic farm. Farm-to-oil products where brands oversee their own farms and processing tend to be the best.
According to scientist and cannabinologist, Dr. Greg Gerdeman, “the scientific discovery of the endocannabinoid system has, in some important ways, liberated cannabis from the drug abuse paradigm.” As researchers continue their vital foray into the medical applications of cannabis extracts, it is our duty as consumers to treat it with the respect accorded to any other drug.
High-quality CBD oil should not cause headaches. Inferior CBD oil and inappropriate dosing are likely reasons why certain CBD users experience headaches. By taking CBD oil at the correct doses and choosing only certified first-class products, we can ensure the purest and most effective relief from the conditions and illnesses that ail us.
Can CBD Flower Give You a Headache?
Over the years, cannabis users have begun associating headaches with low-quality or contaminated weed. Since there’s nothing specific to cannabis that should result in headaches at the time of use, contaminants in cannabis products are usually the cause.
Learn what weed headaches are, how to prevent them, and whether CBD hemp flower makes headaches worse or makes them go away.
Does cannabis cause headaches?
Smoking cannabis has been known to cause headaches in some users, but this symptom is rare and usually caused by substances other than THC. Headache is a common symptom of “ weed hangover ,” though, which can occur after ingesting a large amount of THC.
Scientists have also cautioned people with migraines away from smoking weed as a cure , citing evidence that THC can cause “rebound” headaches in migraine sufferers. Given this evidence regarding THC, you’d be forgiven for wondering if smoking CBD flower could cause headaches as well.
Why did weed give me a headache?
Scientists don’t know exactly why THC can cause headaches in some users. It’s worth noting, though, that THC is a psychoactive chemical that strongly affects your neurochemistry , potentially leading to imbalances that could cause head pain.
Habitual THC users, though, usually end up suspecting that cannabis quality is the main perpetrator of weed headaches. If you use cannabis on a daily basis, you won’t generally experience symptoms of “weed hangover,” leaving differing quality between cannabis products as one of the only remaining viable explanations.
How do you avoid weed headaches?
If you consistently experience headaches after smoking weed, it could be the case that your particular neurochemical makeup simply isn’t compatible with THC. If you only sometimes get headaches when using THC, though, choosing a different product could solve your problem.
Can CBD cause headaches?
Headache is not a commonly reported side effect of CBD. On the contrary, most users report that CBD helps with headaches .
CBD users have provided anecdotal testimony that CBD might be useful for pain ever since this cannabinoid became popular. CBD has also been widely researched for its pain-fighting potential .
The way you use CBD and the quality of the CBD products you use could impact the potential of this cannabinoid to cause headaches. Always choose the purest, highest-quality products to avoid headaches caused not by the CBD molecule itself, but contaminants in CBD formulations.
Should you smoke CBD flower if you get headaches?
Many people who suffer from headaches have reported relief after using CBD hemp flower. Smoking CBD delivers the effects of this cannabinoid quickly and effectively, potentially making smokable CBD products highly useful for headaches, which often onset rapidly.
If you decide to try smoking CBD hemp flower to help with headaches, take the following advice into consideration:

CBD Oil Side Effects – Can it Cause Headaches?
These days we are seeing all the seemingly miraculous benefits of cannabidiol (CBD) pile up. But what about the side effects?
Perhaps you’ve heard anecdotal stories of CBD causing fatigue, diarrhea, and even headaches.
We must keep these stories in mind because for everything we put into our bodies we must first balance all its potential pros and cons.
In this article, we will set the record straight by thoroughly examining the side effects of CBD, specifically if it can produce headaches.
CBD at a Glance
Despite its use in alternative medicine for 3,000 years, the cannabis plant has been illegal for decades.
CBD was only first discovered and isolated in the 1940s at which time its benefits were unknown.
But with the legalization of medical marijuana in some parts of the country, the cannabis craze was officially ignited.
Following suit, the legality of hemp-derived cannabidiol was passed by way of the Farm Bill of 2018.
Due to its only recent legalization, we are just now developing detailed clinical research surrounding the cannabis plant and its many cannabinoids.
CBD is federally legal if it contains less than 0.3% Tetrahydrocannabinol (THC), the psychoactive compound that is prevalent in the illegal substance marijuana.
Since the hemp plant is lower in THC, CBD is most often derived from this variety.
Cannabidiol combines with terpenes and other cannabinoids including low amounts of THC to create full-spectrum CBD oil products .
These oils have hit the health and wellness market, where they are celebrated for their possible benefits for anxiety , pain, and inflammation relief.
Potential Side Effects of CBD Oil
The effects of CBD oil are quite mild. The most common side effects that are reported by CBD users are tiredness, diarrhea, and changes in appetite.
These effects may seem minuscule when compared side-by-side with some prescription medications.
Comparable drugs used to treat the same conditions can have much worse and debilitating side effects. That being said, some people should avoid using CBD:
– People with liver disease should use CBD oil with caution.
– Women who are pregnant or breastfeeding should avoid CBD due to the possible risk of babies’ development.
– Someone who is planning to drive or use heavy machinery when using full-spectrum CBD, especially when first starting treatment or trying a new brand.
– If you have problems with low blood pressure or high blood pressure or are taking blood pressure medications.
Talk to your doctor if you are thinking about taking CBD oil to treat any medical conditions you may have.
This will decrease the risk of side effects occurring. So now that we know who shouldn’t be using CBD, let’s determine what side effects we may expect.
Side effects vary from person to person. Here are the symptoms that clinical research has discovered:
– Changes in appetite/weight: CBD can either increase or decrease appetite. This can result in fluctuations in weight.
– Diarrhea: This is a common unfortunate effect of some CBD oils. This is typically not caused by the CBD itself, but because of the carrier oil (coconut, grapeseed, olive, or hemp oil).
If possible, try not to consume CBD oil on an empty stomach. It may also help to eat some protein with the dose to help reduce how quickly your body absorbs it.
If this still doesn’t help, try CBD capsules, gummies, or topicals to avoid the oils.
– Dry mouth: This 2006 study showed that CB1 and CB2 receptors are present in salivary glands. The receptors are activated with CBD, after which the saliva production decreases, which causes the mouth to dry. Not considered dangerous, this condition will simply prompt you to drink more water.
– Fatigue: Since CBD may be used as a sleep aid for insomnia-sufferers, it makes sense that high doses can cause fatigue and drowsiness. If this is the case for you, don’t take CBD before driving or operating a vehicle.
– Nausea: For some people, ingesting CBD oil can cause mild nausea . This is in direct conflict with CBD helping relieve nausea in some people, as well as increasing appetite. Nausea should go away quickly. If this occurs for you, decrease your dosage.
– Lower blood pressure: Taking CBD in high amounts may cause a small decrease in blood pressure for some people. It happens at the time CBD enters the system, but will not happen to everyone. It may cause a feeling of lightheadedness.
– Dizziness: The feeling of lightheadedness or dizziness is typically associated with a drop in blood pressure. It should pass on its own, or it may help to lay down for a few minutes or snack on something with a cup of tea.
– Vomiting: Although CBD can potentially help reduce nausea and vomiting in chemo patients, it is also said to cause vomiting as a side effect. Unfortunately, some people have trouble digesting CBD oil.
– Anxiety: Even though CBD oil may be helpful in the treatment of some anxiety disorders , it has been also found to increase anxiety in some cases.
– Headaches: It is possible that CBD oil can cause headaches. However, the majority of clinical trials and user experiences do not have headaches as a side effect. More evidence is needed on how and why headaches may occur.
Reasons for Headaches Caused by CBD
Though headaches can be caused by CBD, they are a relatively rare occurrence, compared to other possible side effects listed above.
If you do have a headache when taking CBD, first make sure to rule out other possible factors like:
– Lack of sleep
– Caffeine withdrawal
– Sensitivities to food and drinks, including alcohol
If you do experience a headache caused by CBD, however, it may be from one of the following reasons:
– Taking the wrong dosage for you: Side effects often occur due to taking the wrong dose of CBD. This can happen by overestimating the amount you need, or not monitoring how much you are taking.
For this reason, it is important to always start with a small dose to judge your sensitivity to CBD use. If you start with a low dose, you can gradually work up to the level that works best for you, causing minimal side effects.
It is important that you get the dosage right , and that you are consistent. This will allow for the best results.
– Low-quality CBD: The only FDA-regulated CBD drug on the market today is Epidiolex, a purified CBD extract for two forms of epilepsy.
Due to the lack of FDA regulations in this brand-new industry, there are some producers and dealers out there who just want to make a buck.
As a result, they cut corners when it comes to producing a good quality product. This has created a surge of products on the market filled with harmful chemicals and synthetic substances.
Products that don’t contain organic CBD oil may cause side effects like respiratory problems, allergies, and headaches. Switch to a high-quality CBD oil that is hemp-derived instead.
– The product contains harmful contaminants: The low-quality CBD products can contain solvents like ethanol and isopropanol, or chemicals such as mercury or lead.
Because cannabis is grown and produced all over the world, it can contain different toxins depending on how and where it was grown, and how it was processed.
Not practicing safety protocols or being careless during all of these processes could result in contaminated or diluted CBD.
These products could impact your health with things like headaches, respiratory diseases, and sometimes even death.
– Product hasn’t been third-party lab-tested: Having a product that hasn’t been lab-tested by an unbiased third party will increase the likelihood that it contains ingredients harmful to your health.
On the other hand, testing that is independent and regulated will produce a report of exactly what it is in the product.
This will allow you to see the quality and potency of the CBD. The tests will also give warnings of the use of any chemicals, bacteria, or pesticides that may or may not be in the product.
In this way, you can easily select the CBD oil that has been created with all the best practices in mind.
– CBD may not be for you: Everyone’s body is different and the effects of CBD may vary.
The way your body responds to the dosing could cause a headache if it doesn’t jibe well with your internal chemistry.
That is why it is always strongly recommended to consult your doctor to determine if CBD is right for you.
Pay Attention to Drug Interactions
Another reason to talk to your doctor before taking CBD is to determine whether it can safely interact with any medications you may be taken.
These interactions may increase the severity of CBD side effects. The reason for these negative interactions may be due to CBD’s inhibition of the enzyme cytochrome P450, or CYP450.
This is an enzyme some drugs use for metabolization. As a result, CBD can either increase the drug’s toxicity or decrease its effectiveness.
Some of the medications that negatively interact with CBD may be:
– Blood thinners like warfarin
– Heart rhythm medication like amiodarone
– Thyroid medication like levothyroxine
– Seizure medications like clobazam, lamotrigine, and valproate.
– Rifampin-based drugs for tuberculosis
– Opioids like fentanyl and alfentanil
– Antiarrhythmic drugs like quinidine
– Migraine medications like Ergomar (ergotamine)
– Anticonvulsants like Tegretol (carbamazepine) and Trileptal (oxcarbazepine)
– Macrolide antibiotics like clarithromycin and telithromycin
– Antifungal drugs like Nizoral (ketoconazole) and Vfend (voriconazole)
– Immune-suppressive drugs like Sandimmune (cyclosporine)
– Antipsychotic drugs like Orap (pimozide)
– Benzodiazepine sedatives like Klonopin (clonazepam) and Halcion (triazolam)
– Antidepressants like Remeron (mirtazapine)
The interactions of these drugs can be mild and may not require any adjustment to your treatment.
Or, you may be able to switch your medication with an interchangeable drug that will not interact negatively.
There is also the possibility that you may simply separate the dosing of your medications to different times of day to where they will not interact.
Talk to your doctor about any drugs you are taking, not just prescription medications, but also over-the-counter, herbal, and recreational. He or she will be able to better ascertain your situation.
Reduction of Migraines
Despite the rare occasion that CBD may cause headaches, there is also the possibility that it can have the opposite effect.
There is evidence emerging that cannabis may help with the pain of headaches and migraines.
This could likely be due to both CBD and THC ’s ability to reduce chronic pain and inflammation.
CBD has anti-inflammatory effects that may help with migraine headaches. This may be done through its interaction with the endocannabinoid system (ECS). The ECS regulates a lot of important processes in our bodies including:
– Muscle control
– Immune function
The CBD influences the ECS by interacting with the endocannabinoid receptors.
These receptors regulate pain and inflammation, including TRPV1 receptors, CB1 and CB2 receptors.
THC binds to CB1 receptors that are abundant in the brain and nervous system, reducing the sensation of pain.
Due to the dual effect of both CBD and THC, this may cause added benefits in the treatment of pain.
For this reason, we believe a full-spectrum CBD oil may help reduce the symptoms of chronic migraines.
Though research is still in its early days, there is hope that cannabidiol can become recognized as a safe and effective use for the treatment of these conditions.
May Cause or Treat Headache Pain
Headaches can be a debilitating condition that can greatly affect our daily lives. Finding out what is causing your headaches is important for determining how to treat them.
If you have taken a high dose of CBD oil, or are using a low-quality oil (that has not been third-party tested), these may be possible causes of your headaches.
Though headaches are a rare side effect of CBD oil, the evidence is showing that it can also produce the opposite effect: relief from headache pain.
