Does CBD oil cause memory loss?

It is not certain whether CBD oil can cause memory loss. Existing studies are mixed, with some showing that the cannabinoid may improve memory loss while others claiming that it does not affect memory loss. This article expounds more on the effects of the cannabinoid on memory loss.

Memory loss, whether temporary or permanent, compromises one’s quality of life. Sadly, there is no way to reverse memory loss and all one can do is learn to live with it. Meanwhile, CBD seems is climbing the popularity ladder and there seems to be nothing that it cannot help with. Can CBD cause or improve memory loss? There is insufficient evidence to prove either case. Existing studies show that CBD oil can improve memory loss while others show that it has no effect on mental issues. Peer into this article that explains more about the effect of CBD oil on memory loss.

Introduction to CBD and CBD Oil

CBD is everywhere, from cuisines to body products to the supplement world. With such an increase in its demand, there is a greater need to know what it is. According to Massi et al. (2006) and Bauer et al. (2020), CBD is a non-psychoactive cannabinoid extracted from hemp plants. Hemp belongs to the cannabis class whose members boast chemical compounds called cannabinoids, and CBD is of them. Many people are attracted to CBD and its products because of its non-psychoactive nature. It is intoxicating and cannot cause the ‘high’ effect of smoking weed.


The body cannot directly CBD absorb as a compound. Thus, CBD companies incorporate the cannabinoid into compounds that the body can absorb. CBD oil is one of such forms, featuring oils as the base carrier. Most CBD brands use MCT coconut, extra virgin, and hempseed oils as the base carriers. The body cells cannot absorb CBD but when it dissolves in such base carrier oils, they absorb CBD molecules. Among the many products at the JustCBD store are CBD oils and CBD tinctures.

Types of CBD Oil

Do you want to venture into the CBD regime and want CBD oils to be your ideal deliverable method? You should know the types of CBD oils, including;

  1. Full-spectrum CBD; features CBD with the whole range of cannabinoids, including the psychoactive THC. Also has terpenes and flavonoids, which, according to VanDolah et al. (2019), lead to a full entourage effect. One of the products in our inventory is the JustCBD full-spectrum oil that you can order online.
  2. Isolate-based CBD; is pure CBD without any other hemp compound in the form of terpenes, flavonoids, or additional cannabinoids.
  3. Broad-spectrum CBD; is like full-spectrum CBD but does not have the psychoactive THC. It is great for those looking for a full entourage effect without THC.

Does CBD Cause Memory Loss?

CBD is relatively new and much is yet to be understood about it. According to Corroon & Phillips (2018), the cannabinoid has a great safety profile, showing that it is good for consumption. Still, many ask if the side effects linked to it might be memory loss. So far, studies have not provided sufficient evidence to show that taking CBD oil might make you lose your memory. In fact, one study claims that the oil can improve memory abilities. According to Oreja-Guevara et al. (2015), CBD seemed to improve cognition and memory dullness. Still, this does not mean that the cannabinoid is an alternative medicine to memory loss. If anything, the FDA has not approved of using CBD oil for memory loss, and until studies show beyond doubt that the cannabinoid might boost memory, we do not recommend it for this.

What Other Studies Say about Memory Loss

Scientific research has not provided enough evidence to show that CBD might make a person lose his memory. Is that all? While one study quoted above showed that taking CBD oil might improve cognition and mental dullness, not all studies are projected toward the same angle. Instead, they are mixed, and some suggest that the cannabinoid might have on memory. According to Casciato et al. (2020), CBD oil does not affect memory. In the study, flies were given CBD and observed if they would remember some things but they did not. The research concluded that CBD did not improve memory, contrary to the early findings that the cannabinoid can boost memory.

How Much CBD Oil Should You Take?

Watt & Karl (2017) stated that CBD is therapeutic and many people want to benefit from these properties. Do you want to take CBD oil? One question that people ask while anticipating taking CBD is how much of the cannabinoid they should take. Interestingly, there is no one-size-fits-all CBD amount for all CBD users. Rather, how much you can take depends on the following factors;

  1. Previous exposure to CBD oil or CBD history; the more you take CBD oil, the more the body gets used to it. At first, you keep the potencies and concentrations low but increase this as you get more exposed to it.
  2. CBD potencies; the more potent the CBD oil, the less you need to take to feel CBD effects, and the reverse is also true.
  3. Why you are taking CBD oil; if you are taking CBD for general well-being, you don’t need as much as you would take for a health condition.
  4. The severity of the condition; how severe the condition for which you are taking CBD oil is affects how much of the cannabinoid you need to take. Acute random pain my not as much CBD oil for severe and long-lasting pain.

How Long Does CBD Oil Take to Work?

There is no exact time that CBD takes to work for all users. Generally, it takes 15- 60 minutes to kick in, depending on the many factors. For instance, if your inherent body factors and metabolism are CBD-favorable, the cannabinoid takes effect fast. Other factors affecting how long CBD oil takes to work include the potency of the oil, how much you have taken, CBD oil history, and how full the stomach is as you take CBD oil.


Studies are mixed and it is unclear whether CBD can cause memory loss. Some studies show that the cannabinoid may improve memory loss and cognition while others reveal that it does not affect memory in any way. This article looks at the effect of CBD on memory and also expounds more on the non-psychoactive cannabinoid of scientific interest to many.
