Can Effects of CBD Oil Cause Headaches And Allergies?

It will be reinventing the wheel if we take time to comprehend and discuss the medicinal benefits or effects of CBD oil.

Like many types of research came into existing that declared heaps of information about CBD oil’s optimum usefulness, there is some misunderstanding that effects of CBD oil cause adverse effects like headaches and allergies.

So what exactly is CBD oil?

Cannabis sativa plant has many classes that include Cannabidiol or CBD which is one of the active 113 cannabinoids.

It is not an only non-psychoactive component of a plant but also contains immense therapeutic properties that are used to treat many major and minor diseases and illnesses with minimal or no side effects. CBD constitute up to 40% extract from the plant, making itself a major phytocannabinoid.

However, the component that contributes to cause downregulating – “high feeling” in cannabis users is Tetrahydrocannabinol (THC).

Present in abundance in raw hemp or marijuana is, therefore, a psychoactive constituent of cannabis, hence unsafe and illegal in the U.S.

CBD oil, on the other hand, the extracted element from the leaves of the crucial plant is apparently announced as a non-toxic natural ingredient.

Although there are still some people, who believe that CBD oil despite having immense benefits still withhold adverse effects like headaches and allergies. Let’s clear out the air!

Does CBD oil really cause side effects like allergies and headaches?

It is a pretty standard concern for people who are new to any drug or supplement to ask about the side effect that appendage may have.

However, concerning CBD oil and its human consumption, some researches have been done to identify possible effects.

According to a study, documented in 1986 in the International Journal of Neuroscience showed side effects in dystonic CBD users, these effects include dry mouth, hypotension sedation, psychomotor slowing, and lightheadedness. However, all of these symptoms are highly based on doses of CBD.

To our concern, there were no adverse effects of CBD oil such as headaches and allergies. The latest Cannabis and Cannabinoid Research in 2017 comprehensively cleared that CBD might cause side effects related to GIT such as diarrhoea, changes in appetite/weight, and tiredness.

Similar to the previously stated study, CBD still has a good side effect profile when it comes to safety and effects comparatively to various other medicinal drugs and supplements.

It is worth noting that CBD dosage plays a major role in causing some of the side effects in people, but it will happen if particular conditions are met. These conditions lie in the category of dose and quality of CBD oil.

However, it is scientifically proven that high dosage of CBD is non-toxic and significantly cause no harm, yet it is essential that an individual start with a moderate quantity and gradually increase the amount depending upon the body’s need and severity of the illness.

Another most highlighted issue that might cause negatives like headaches and respiratory allergies is the poor quality of CBD oil.

Since CBD oil could be taken through some modes like ingestion, inhalation, intravenous application, and topical, it is not new that one thing which flourishes in the market has million other cheap substitute products to attract the users.

Two main things before buying CBD oil is to ensure the sources and origin of the fancy material.

Importance of CBD oil quality

Unfortunately, the market is filled with a lot of poor quality of CBD oil from unreliable brands. It can be challenging for consumers to educate themselves about the sources rightfully. Hence, there are a few points that we have jotted down for your ease:

  • CBD oil purity and safety

Since cannabis plant absorbs chemicals such as lead and mercury from the ground, the origin of the plant matters.

Many CBD oils are imported from overseas that may contain a minimal amount of CBD oil only legally to announce the product. These fake copies do not show any results and might cause adverse reactions.

  • Third-party lab test

Always look for the CBD product which is third-party lab tested to ensure the potency, quality, residual solvents, and terpenes.

The laboratory testing also determines the use of pesticides, harmful chemical fertilizers if used, and microbial contamination.

  • Product labelling

Product labelling is also an important piece of information that every buyer should be aware of. Proper labelling on CBD oil product would determine the name and place of the product’s manufacturer, identify consumer’s commodity, and determine contents with clear details.


Although CBD oil and its related products are safe to use, proper research and knowledge about the product before you buy is crucial.

While every human has different body chemistry, some people might feel nothing after CBD ingestion; some would experience minor effects.

Headaches and allergies after CBD use are, however, uncommon and could be related to the inferior quality of CBD oil.

Always consult with a healthcare professional regarding your condition and dose of CBD oil.
