can cbd cause headache- cbd blogs

Nowadays, CBD oil has been widely used worldwide for different purposes, especially for headaches, without knowing its side effects. Some people suggest that CBD oil helps relieve migraines, but due to limited research on cannabidiol plants, we can not put any conclusion regarding its therapeutic effects on the brain. So the question arises, can CBD oil cause a headache? 

What is CBD oil? 

The cbd oil comes from The cannabis sativa plant, which naturally contains more than 80 active substances known as cannabinoids, including cannabidiol. CBD oil is prepared with a specific concentration of CBD and can be created by extracting CBD into a thick, oily paste and combining it with a carrier oil. 

Who should avoid taking CBD oil? 

CBD oil has relatively moderate effects. Tiredness, diarrhea, and changes in appetite are the most frequent side effects that CBD users experience. These side effects could appear negligible when put side by side with some prescription medications. Similar medicines used to treat similar diseases can have considerably harsher and crippling adverse effects. The following individuals ought to refrain from utilizing CBD:

  • Pregnant women should refrain from consuming CBD oil due to the potential risk to the development of the unborn child.
  • People with liver illness should take CBD oil with caution. 
  • Full-spectrum CBD users who intend to operate heavy equipment or drive, especially when just starting a treatment or experimenting with a different brand. If you take blood pressure medication, your blood pressure is either too low or too high.

Consult your doctor before taking CBD oil if you’re thinking about using it to treat any potential medical issues.Now that we know who shouldn’t use CBD let’s explore the potential negative impact.

Potential adverse effects of using CBD oil

People react differently to cbd oil side effects. Clinical studies have identified the following signs:

Appetite/weight changes

CBD makes you eat more or less. Weight changes may be the outcome of this. 


Diarrhea is a frequent side effect of various CBD products. The carrier oil (coconut, grapeseed, olive, or hemp oil) is usually to blame for this rather than the CBD itself. Avoid using CBD oil when you are hungry if at all feasible. It is also beneficial to eat some protein along with the dose to slow down how rapidly your body absorbs it. Try CBD candies, pills, or topicals rather than oils if this doesn’t work. 

Dry mouth

The 2006 study demonstrated the presence of CB1 and CB2 receptors in the salivary glands. After CBD activates the receptors, less saliva is produced, which causes the mouth to become dry. This condition won’t harm you; it will make you want to drink more water. 


Given that CBD may be a sleep aid for insomnia, it makes sense that excessive doses could make people feel tired and sleepy. If this applies to you, avoid using CBD before operating a vehicle. 


CBD oil consumption may produce moderate nausea. This directly conflicts with the fact that some people may experience nausea relief and hunger stimulation from CBD. Vomiting should disappear rapidly. If this happens to you, reduce your dose.

Lower blood pressure

For some people, using high doses of CBD may result in a slight drop in blood pressure. It occurs when CBD first enters the body, but not everyone will experience it. A sense of dizziness may result. 


A reduction in blood pressure is frequently linked to the sensation of being lightheaded or dizzy. It should go away independently, but lying down for a while or having a snack and a cup of tea might help.


Although CBD may be able to benefit chemotherapy patients who are experiencing nausea and vomiting, it is also known to have the adverse effect of making people throw up. Sadly, some people find it difficult to metabolize CBD oil.  


Even though CBD oil may be effective in treating some anxiety disorders, it has occasionally been shown to make people feel more anxious. 


There is a chance that CBD oil will give you headaches. 

However, the majority of user reviews and scientific studies do not list headaches as a negative effect. To fully comprehend how and why headaches could occur, more information is needed.

Can CBD cause headaches? The Causes and Effects

Compared to other potential side effects outlined above, headaches are comparatively uncommon, even if CBD can induce them. If you do get a headache after using CBD, be sure to rule out any additional potential causes, such as:

– Dehydration, Stress, Insomnia, Fatigue, Hunger, and Caffeine Withdrawal

– Food and drink sensitivities, especially alcohol sensitivity

The incorrect dosage for youThe incorrect dosage of CBD frequently results in side effects. To determine your sensitivity to CBD consumption, it is crucial to always start with a minimal dose. Starting with a low dose allows you to gradually increase to the amount that best suits you while having the fewest adverse effects possible. You must use the proper dosage and remain consistent. This will enable the finest outcomes.
Low-quality CBDEpidiolex, a refined CBD extract for two types of epilepsy, is the only CBD medication currently approved by the FDA and available on the market. Some producers and dealers in this new market are only interested in making a profit because there are no FDA restrictions. They consequently need to make compromises when creating a high-quality product. So I suggest you change to high-quality CBD oil made from hemp instead.
The product has dangerous contaminantsCBD goods of lower quality may contain chemicals like lead or mercury and solvents like ethanol and isopropanol. As CBD is created around the world through different procedures thus, toxins can vary depending on how, where, and under what conditions it was created. These procedures can potentially produce contaminated or diluted CBD if safety precautions are not taken, or care is not taken.
Not subjected to independent laboratory testingThe likelihood that a product contains substances hazardous to your health will rise if it has yet to be lab-tested by an impartial third party. On the other hand, independent, controlled testing will result in a report detailing every ingredient in the product. Choosing CBD oil that was produced to the highest standards will be straightforward for you as a result. 
CBD might not be suitable for youThe effects of CBD may differ depending on the individual’s physique. If your body’s reaction to the dosage doesn’t agree with your internal chemistry, it could give you a headache. That is why I will always highly advise you to speak with your doctor to decide whether CBD is appropriate for you.

Can Cbd cause headaches?

On rare occasions, CBD may result in headaches, but there is also a chance that it may have the opposite effect. There is growing evidence that cannabis may lessen headaches and migraine pain. CBD contains anti-inflammatory properties that could ease migraine symptoms. Its interaction with the endocannabinoid system (ECS) may do this. The ECS controls numerous significant bodily functions, including mood, memory, appetite, regulation of muscles, immune system, inflammation, and pain. 

How can Cbd treat a headache? 

In rare cases, CBD helps treat headaches because of the Endocannabinoid receptor interaction that CBD affects the ECS. These receptors, which include TRPV1 receptors, CB1 receptors, and CB2 receptors, control pain, and inflammation. THC reduces pain perception by attaching to the many CB1 receptors in the brain and nervous system. Due to the dual effects of CBD and THC, there may be additional advantages in managing pain as a result. Because of this, a full-spectrum CBD oil could lessen the impact of persistent migraines. Even though the research is still in its early stages, there is optimism that cannabidiol will be accepted as a safe and reliable treatment for various ailments.

This means that Cbd oil might trigger a headache in some patients, while others may find it beneficial to treat it.

Although it cannot be used to prevent headaches, the qualities of CBD do suggest that it can be used to cure them.
