The endocannabinoid system has very widespread effects throughout the body and has the potential to be used therapeutically and medicinally. Research suggests that cannabidiol (CBD) may be helpful as a therapeutic treatment for certain neurological conditions.
5 Ways CBD Affects Your Brain
Cannabidiol (CBD) is a non-psychoactive chemical made by cannabis plants. In most cannabis plants, CBD is the second most common chemical produced. THC is the most common chemical produced by most cannabis plants. Though many people think about THC when they think about marijuana, CBD is becoming more popular due to its numerous health benefits.
Relieves Anxiety and Depression
Many people are familiar with marijuana’s ability to help alleviate anxiety. While THC helps some people feel more relaxed and calm, it can actually increase anxiety in other people. This has led researchers to examine CBD as a treatment for anxiety and depression instead.
For instance, in one study, researchers examined the effects of CBD on the brain and anxiety levels. The researchers discovered that CBD reduces blood flow to areas of the brain linked with anxiety, such as the hypothalamus, which usually become overactive in people with anxiety disorders. It was also found that CBD reduced overall anxiety, with participants reporting lower anxiety levels after having received the chemical.
CBD may also be effective as an antidepressant. CBD appears to work by balancing the dysfunction in the endocannabinoid system in people with depression. Additionally, CBD has been found to work on a serotonin receptor that influences depression symptoms.
These studies have opened doors for both patients and clinicians. While antidepressants can take weeks to work and cause side effects, CBD works immediately without many side effects.
Protects Brain Cells from Harm
Although many believe that marijuana damages the brain, studies indicate that some components of cannabis, such as CBD, can actually protect brain cells from harm. In fact, in 1999, the United States Department of Health and Human Services actually obtained a patent for the neuroprotective effects of cannibinoids. The patent states that cannabis and its chemical properties can protect brain cells in individuals with neurodegenerative diseases, such as Alzheimer’s disease, Parkinson’s disease, and other types of dementia.
CBD’s neuroprotective effects are related to its effect on CB2 receptors in the brain. CBD acts on CB2 receptors to create anti-inflammatory responses in immune cells located in the brain. This reduces the extent to which damage to the brain is caused by inflammation.
Oxidation contributes to brain tissue damage and is partly responsible for the brain damage seen in individuals with conditions like Parkinson’s disease and Alzheimer’s disease. Research indicates that CBD acts on CB2 receptors to decrease oxidative damage.
Activates the Endocannabinoid System
The endocannabinoid system is comprised of CB1 receptors, which are mainly located in the brain, and CB2 receptors, which are mostly located on immune cells. Chemicals like THC and CBD activate the endocannabinoid system when marijuana is consumed. THC binds with CB1 receptors in the brain, producing psychoactive effects, such as pain relief, heightened mood, short-term memory impairments, and hunger.
Unlike THC, CBD does not activate CB1 receptors. That’s why CBD doesn’t have any psychoactive effects. Rather, CBD interacts with CB1 receptors in a way that inhibits chemicals, such as THC, from binding to CB1 receptors. CBD decreases many of the psychoactive effects THC can have, such as memory problems and anxiety.
Additionally, CBD increases anandamide levels within the brain. Anandamide is one of the few natural cannabinoids made in the body. Anandamide has a part in regulating other chemicals in the brain like dopamine and serotonin.
Relieves Inflammation and Pain
Cannabis has been used to alleviate pain for thousands of years. While the pain-killing ability of THC has long been known, studies indicate that CBD can effectively relieve pain as well. CBD helps manage pain by acting on CB2 receptors, which are mainly located on immune cells. The CB2 receptors are responsible for managing some cellular functions.
One of the cellular functions CB2 receptors are responsible for managing is suppressing the inflammation response created by immune cells. CBD decreases the amount of inflammatory molecules, such as chemokines and cytokines, that are present at sites of inflammation. CBD’s ability to decrease inflammation peripherally helps block pain signals from going to the brain.
Fights Psychosis and Seizures
CBD can also be effective in managing epilepsy. CBD seems to manage seizures by lowering the degree of excitation of cells in the brain that play a part in seizures. CBD stops the brain mechanisms that contribute to seizures by enhancing the release of the inhibitory neurotransmitter GABA.
CBD also has antipsychotic effects. CBD increases anandamide in the brain. Increased levels of anandamide in the brain have been associated with decreases in psychotic symptoms.
CBD possesses numerous health benefits and can help manage both medical and mental health conditions. If you are interested in using cannabis to help manage your health, please call LifeBoost to pre-qualify for the use of medical cannabis.
CBD and the Brain: The Impact of Cannabidiol on Brain Health
Scientists are just beginning to unveil the therapeutic benefits of cannabidiol (CBD). As new discoveries come to the forefront, we are learning that CBD could give your brain health a major boost, due to its ability to protect brain cells from the harms of traumatic brain injuries (TBIs), stroke and neurodegenerative disorders like Alzheimer’s and Parkinson’s disease.
Learn about how CBD affects the brain, the neurological conditions the cannabinoid may help treat, and how to use it for maximum effect.
How CBD Affects the Brain
Before we can understand CBD’s effects on the brain, we need to understand how the endocannabinoid system (ECS) works. Your ECS plays a fundamental role in homeostasis or balance. The ECS is involved in fertility, appetite regulation, pregnancy, pre- and postnatal development, pain sensation, mood, the pleasurable effects of voluntary exercise and the formation of memory.
The ECS plays an important part in the development and plasticity of the human brain throughout a person’s lifetime, with endocannabinoids like anandamide and 2-arachidonoylglycerol (2-AG) playing a very important role in protecting the brains of newborns and the maturation of the adolescent brain.
When the ECS is disrupted, or if a person’s genetics do not encode cannabinoid receptors or endocannabinoids properly, health problems occur. The ECS can be disrupted by injuries or illnesses, which can form a part of an inflammatory event (e.g. a long-term viral or bacterial infection) that can cause both short- and long- term changes to the functioning of the ECS.
Age also plays a factor in how the ECS functions, just as the brain changes over the course of one’s lifetime. Keeping the ECS “in balance” could therefore help overcome or theoretically even prevent conditions that affect the human brain as it ages.
There are several neurological and mood disorders which are linked to disruption to the ECS, and there is some good evidence suggesting that the ECS is a key modulator of sociability, emotions and cognition. Some of these conditions are genetic and can occur at any age, while others are more likely to occur as we age (although there may still be a genetic component). Some are also autoimmune conditions.
There are several studies and reports suggesting that CBD and other cannabinoids (including THC in some instances) may be useful for the treatment of neurological and mood disorders such as:
, particularly childhood forms of epilepsy such as Dravet syndrome and Lennox-Gastaut syndrome.

CBD vs. Other Cannabinoids
CBD is not the only cannabinoid that may help people with neurological conditions. Its psychoactive counterpart, THC, has been shown to affect the brain in different ways as well, although not all of these are positive.
As a general rule, CBD works best in combination with THC and other cannabinoids, such as cannabigerol (CBG) and cannabinol (CBN). This chemical “team effort” is known as the entourage effect.
Potential Health Benefits
CBD and other cannabinoids including THC may present the following neurological health benefits:
- Help reduce neuroinflammation (inflammation in the brain)
- Facilitate neurogenesis (growth of new brain cells)
- Help with excitotoxicity (damage to nerve cells caused by prolonged activation of an excitatory neurotransmitter, commonly glutamate)
- Decrease hypothermia – CBD and THC may reduce body temperature , potentially lowering blood pressure , potentially easing certain cardiac conditions like arrhythmia
- Fewer motor and autonomic deficits in those with spinal cord injuries
- Enhancing anandamide signaling – disruption of which is implicated in autism
Research into these possible health benefits of CBD is ongoing, and more clinical trials are necessary.
Is CBD a Nootropic?
Nootropics are drugs that improve cognitive performance, including attention span, memory and even creativity. Some researchers consider CBD to be a nootropic, but there is currently no consensus in the scientific community.
CBD could be considered a nootropic because of its potential to improve blood flow in the brain, easing anxiety and depression and potentially treating conditions that affect the memory, like Alzheimer’s and PTSD. When people feel less anxious and less depressed, they are more likely to pay attention, remember things and be creative.
Using CBD for Brain Health
Effectively using CBD for brain health means pinpointing the best product, dosage and treatment duration for you.
Many CBD products may offer brain benefits, but we cannot say this for sure as there is little research to evaluate their efficacy. You can choose from CBD topicals, CBD edibles, sublingual CBD tinctures and smokable CBD products. Some CBD products may be better for treating insomnia (especially products containing higher amounts of myrcene and linalool), while others are designed to help people with anxiety and depression (where terpenes like limonene may be more helpful).
Dosing CBD is very much a customized process and depends on your personal needs and treatment goals. Beginner CBD consumers may start with as low as 5 milligrams (mg) of CBD per day, while more experienced consumers may take up to 100 mg per day, or potentially even more. Tweaking CBD dosages is common and the amount of CBD that feels good today may change in the near future.
It is also worth remembering that CBD has different effects at different dosages (i.e. it has biphasic effects). Lower doses (under 15 mg) of CBD may have more stimulating effects, whereas higher doses may have more sedative effects. Again, the effect CBD has and at what dose is very much individual, so take this as a rough guide. Check out our guide to dosing for more information.
One study found extended CBD use (twice daily for 10 weeks) to be beneficial. The researchers determined that, “Prolonged CBD treatment appears to have promising effects for improving psychological symptoms and cognition in regular cannabis users.”
Speak with your doctor about CBD dosing guidelines of how often and for what duration would be best for you personally.
The Bottom Line: CBD’s Impact on Brain Health
CBD appears to have numerous potential benefits for brain health. Improving focus, relieving anxiety, and reducing inflammation are just a few ways that the cannabinoid could strengthen your brain.
