Why Does CBD Give Me a Headache?

One of the most frequently disturbing aspects of everyday life is the sudden onset of a headache. These prickling, stabbing pains beset everyone eventually, and occur for a variety of different reasons. And we have been trying to find a way to get rid of them for decades.

Only recently have people started to consider CBD oil for headaches. So, how about it? Can CBD be useful for treating headaches?

What Is a Headache?

The first thing to learn when considering whether or not headaches can be treated using CBD oil is to understand what a headache is, to begin with. Broadly speaking, headaches are any kind of pain in the head or face area. In fact, that pain can also extend across the upper neck or some of the muscles in the back.

Most commonly, headaches are described as a sensation of muscle contraction, inducing pain throughout the muscles in your head. Typically, these happen due to spasms, for a variety of different reasons.

The irritating thing about headaches is that they seem to have a high number of different causes. A headache in the back of the head might be a result of a head injury; or, it could be brain encephalitis. That general frontal head pain could be too much screen time at work; or, it could be the onset of a severe viral infection.

Headaches are so nonspecific and varied that just describing every pain in the head as a headache is simply too vague. This is why the classification goes a bit further and typically stratifies headaches into different categories, or types. So, what are these different types of headaches?

What Are the Different Types of Headaches?

Most headaches get defined into one of three main categories: Primary headaches, secondary headaches and other, general headaches, like facial pain.

Primary headaches are typically what you think of when you hear about a headache. They refer to headaches as a result of migraines or tension pain within the brain. Common primary headaches have all sorts of names, including things like tension headaches, migraine headaches, and cluster headaches. Tension headaches are more common and occur due to adverse stress or other medical conditions. Migraines and cluster headaches are something altogether more horrifying, causing massive amounts of pain for seemingly no reason.

Secondary headaches are the result of things like dental pain or muscle or bone issues, causing stress and pain that leads to a headache.

General headaches encompass all kinds of different headaches, including one known as a rebound headache. These are a result of medication overuse, where using too much of a drug can induce pain in the head.

Headaches are just something that all of humanity has to deal with for all kinds of strange and inconvenient reasons. Being able to figure out why headaches happen and how to get rid of them would undoubtedly be very helpful.

What Causes Headaches?

Generally speaking, headaches have a few specific and detailed reasons for affecting you, though there are plenty of times when the reasons might be pretty mysterious.

Primary headaches, the ones you usually experience, tend to stand on their own as the affliction. They occur due to too much activity, or irritation of the brain. This can mean that your brain tissue, muscles, or even the blood vessels throughout your head have become overstressed.

They can also occur due to lifestyle changes, or altered chemical intake and reactions throughout the body. For example, you can get headaches due to not getting enough sleep or having too much stress in your life. Furthermore, eating and drinking certain things, like too much alcohol, drinks with high sugar content, or overeating fatty or nitrate-rich foods can cause headaches as well.

Sometimes, the precise causes of headaches can also be a weird mix of many different things. You can experience severe secondary headaches as a result of dental pain. Badly growing teeth or malformed jawbones can produce head pain through excess pressure, resulting in a terrible headache.

Ultimately, almost everything can potentially cause headaches, as a headache is such a general and all-encompassing term to describe what is a very complicated part of your body. If you have a headache, however, you likely have something wrong with you that needs treatment.

Before we can discuss taking CBD oil for headaches, however, we need to understand if it is safe. Is there any risk that CBD oil might cause headaches?

Can CBD Oil Cause Headaches?

Considering that we are thinking about CBD oil as a potential treatment for headaches, it would be strange to think of CBD oil as causing them, wouldn’t it?

However, as your body can create headaches due to changes in body chemistry, or in taking new drugs, we need to be careful. Even if CBD oil itself is not dangerous, our bodies could have a headache just because we tried something new.

While many people purport CBD oil to be almost side-effect-free, there are a few things to keep in mind. The main side effects of CBD include a slight tendency towards sleepiness, as well as a drop in blood pressure and things like dry mouth.

Headaches, however, are not a listed side effect of CBD. If you were to take CBD for the first time and find yourself having a headache, you shouldn’t worry. If you get a headache just after taking it, it is likely a result of something else entirely.

Thankfully, CBD oil headaches are not common.

So, how can we use CBD oil to help with headaches?

Can CBD Oil Help with Headaches?

CBD oil has long been taken to treat headaches, in much the same way that marijuana has been used for headaches as well.

Though there is still a considerable quantity of research to be done in figuring out the full effects of cannabis on our bodies, it would appear to show some potential.

One study by Lochte B.C. for the Journal of Cannabis and Cannabinoid Research found that there was insufficient research to determine its use as a treatment for headaches. However, they also found that there were innumerable instances of anecdotal and preliminary results, indicating that it would indeed be incredibly useful.

This means that it is difficult to definitively prove, as there simply are not enough completed studies out there to demonstrate its capacity as a headache treatment. This is in spite of the sheer number of people that it already helps.

However, there are, in the very least, a few studies. A study by Leimuranta P. for the Journal Frontiers in Pharmacology found that cannabinoids are incredibly useful when it comes to headaches. Though the precise mechanisms are still unclear, they noticed a clear trend in treating headaches.

Ultimately, though, the issue comes down to anecdotal evidence. This is because many of the medicinal uses of cannabinoids are still relegated to illegalities or hearsay. Not enough people in positions of power care about cannabis products sufficiently to approve enough studies about them.

Until we reach that wonderful, scientifically beneficial point, we need to rely on hearsay and conjecture, as well as the few studies already published. And, of those studies already done, we can very clearly see that CBD oil does indeed help with headaches a great deal.

But how much should you actually be taking?

How Much CBD Oil to Take for Headaches

Deciding to start using CBD oil for headaches is all well and good, but what about the actual methods for doing so? For those just getting into it, trying to understand how much CBD oil to take at a time can feel pretty confusing.

The thing to bear in mind is that there isn’t really a specific CBD dosage for every person. How much CBD oil you should take at one time depends on your total weight. Precise CBD oil dosage is more about guesstimation and experimenting than it is about following exact formulas. To make it easier, however, many brands provide a rough guide to get you started, allocating a small checklist and weight recommendation for you to follow.

This means that, if you are inexperienced with CBD oil, you should probably stick to the major brands to get a CBD dosage guide reliably.

Once you have decided on a brand, a dosage, and to take some CBD oil, how long can you expect it to take to work?

How Long Does CBD Take to Prevent Headaches?

The tricky thing about using CBD oil medicinally is that there isn’t any consensus on how long it is supposed to take. This is because the time it takes for CBD oil to take effect can vary depending on how you take it.

If you were taking it as a regular CBD oil sublingually, which means placing it under your tongue, it would take effect faster than if you were to take it orally, like with a capsule.

Once again, it is also tied to your body chemistry and how quickly your body deals with things. Your endocannabinoid system, which is the bodily system responsible for working with cannabinoids, both internal and external.

Some people have faster endocannabinoid system uptake, whereas others are far slower. Some people have almost no functioning ECS, making external cannabinoids practically useless on them.

For taking CBD oil to combat headaches, scale your expectations based on how frequently you get them. If you only irregularly get infrequent, uncomfortable headaches, you might notice an effect within a few hours.

However, if you suffer from periodic, regular migraines, then perhaps give it around three months.

Your body can take time to adapt to various changes in your diet and body chemistry, so it is possible that CBD oil might take just as long to take hold as well.

If you are going to take CBD for headaches, you are going to need to have a little patience.

Final Thoughts on CBD Oil for Headaches

CBD oil for headaches is one of those tried and tested treatment options that people have been using for decades in the USA. People have been using cannabinoids to treat headaches for millennia all over the world, but it is only recently that it has begun being popular again.

No one wants to have to suffer a headache, especially those that suffer frequent migraines or cluster headaches and trying something new to combat it can often feel scary.

However, when it comes to taking CBD oil for headaches, you do not need to worry. CBD oil has no side effects or significant consequences, nor is there any reason to concern yourself. Really the only thing you need to do is take the appropriate amount for your weight, have some patience, and, above all, wait. While it is possible that CBD oil for headaches just might not be for you and your body, you need to make sure to give it the necessary time to work.

After a few days or months, you will know one way or another whether or not CBD oil is the right choice for you to treat your headaches.

I thought CBS was to help migranes not give it.ive just purchased cbd and wow scared of trying it now after listening to u all


This article is titled, “Why does CBD oil give me a headache?” and the whole article is about how CBD treats headaches, with a small section about how headaches aren’t caused by CBD. I get a horrible headache every time I use some kinds of CBD, which also includes body aches, specifically in my neck and upper back. I believe it’s related to the quality of the product, so if I get a headache, I know the brand is not good for me.


Has anyone experienced weight gain while taking CBD OIL?

Began a quality, organic cbd oil from my local compounding pharmacy. Started out taking 2.5mg two times a day for 2 days then increased to 5mg for a day and a half (3 times)…woke up w a severe headache after the 2nd dose, but took the 3rd dose hoping it was unrelated and might actually help. Nope, so bad I couldn’t get out of bed and have an ice pack. Does anyone think it could be related to cbd causing detox?


I have a bad back due to my military days. So I decided to use CBD to help. But after using CBD I developed a headache. It’s a mild headache in the left side of my head at the temple and around my eye socket that last for many days. Discontinued using CBD maybe it’s just not for me.


Every time I take cbd oil, I get a headache


I started taking a Cbd candy about 2 weeks ago, to see if it would help with my sleep and Fibromyalgia. Well, 1st night, headache aprox 1 hr after taking it. I tried again SIX times. I wanted to make SURE it wasn’t a coincidence. Each time I took it, like clock work, aprox 1 hr after, I got a headache. I’m SO upset because I really had hopes Cbd would help me. Now I’m SO discouraged and haven’t taken it anymore. The one I tried was a candy. I’m not sure if other types or companies would be better… Read more »
