These studies yield promising results, but cannot definitively determine that CBD improves anxiety. Larger, well-designed trials must be conducted to confirm the association between CBD and improved anxiety. For now, you can also try these strategies to reduce stress.

Our current reality is undoubtedly anxiety-inducing. And understandably, demand for household products such as toilet-paper and hand sanitizer has spiked in response. But perhaps more surprising is the surge in e-commerce sales of self-care products containing CBD oil. CBD is perhaps best known for its beneficial effects on anxiety and sleep, and up until recently, this was merely hearsay.[1] The past five years have been pivotal for the legalization of CBD and its use in clinical trials. But does the science support the hype behind this craze? We’re laying out the research so you can be an informed consumer.

CBD likely has a dose-dependent effect on sleep—it appears that low doses are stimulating and keep you awake, but larger doses have a sedating effect and can improve sleep time and wakefulness during the night.[16,17] But scientific evidence behind these effects is limited and the mechanism behind them is not yet clear. Further trials are warranted, and until then, check out these proven ways to improve your sleep.

Keywords: Cannabis (marijuana); cannabidiol; delta9-tetrahydrocannabinol; functional MRI; neuroimaging.

Background: Accumulating evidence suggests that the non-intoxicating cannabinoid compound cannabidiol (CBD) may have antipsychotic and anxiolytic properties, and thus may be a promising new agent in the treatment of psychotic and anxiety disorders. However, the neurobiological substrates underlying the potential therapeutic effects of CBD are still unclear. The aim of this systematic review is to provide a detailed and up-to-date systematic literature overview of neuroimaging studies that investigated the acute impact of CBD on human brain function. Methods: Papers published until May 2020 were included from PubMed following a comprehensive search strategy and pre-determined set of criteria for article selection. We included studies that examined the effects of CBD on brain function of healthy volunteers and individuals diagnosed with a psychiatric disorder, comprising both the effects of CBD alone as well as in direct comparison to those induced by ∆9-tetrahydrocannabinol (THC), the main psychoactive component of Cannabis. Results: One-ninety four studies were identified, of which 17 met inclusion criteria. All studies investigated the acute effects of CBD on brain function during resting state or in the context of cognitive tasks. In healthy volunteers, acute CBD enhanced fronto-striatal resting state connectivity, both compared to placebo and THC. Furthermore, CBD modulated brain activity and had opposite effects when compared to THC following task-specific patterns during various cognitive paradigms, such as emotional processing (fronto-temporal), verbal memory (fronto-striatal), response inhibition (fronto-limbic-striatal), and auditory/visual processing (temporo-occipital). In individuals at clinical high risk for psychosis and patients with established psychosis, acute CBD showed intermediate brain activity compared to placebo and healthy controls during cognitive task performance. CBD modulated resting limbic activity in subjects with anxiety and metabolite levels in patients with autism spectrum disorders. Conclusion: Neuroimaging studies have shown that acute CBD induces significant alterations in brain activity and connectivity patterns during resting state and performance of cognitive tasks in both healthy volunteers and patients with a psychiatric disorder. This included modulation of functional networks relevant for psychiatric disorders, possibly reflecting CBD’s therapeutic effects. Future studies should consider replication of findings and enlarge the inclusion of psychiatric patients, combining longer-term CBD treatment with neuroimaging assessments.

Conflict of interest statement

The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

The Neuropsychopharmacology journal published a relevant study in 2019. It analyzed the impact of CBD on brain excitation and inhibition systems. The researchers recruited 34 male volunteers, half of whom had autism spectrum disorder (ASD). They found that CBD potentially shifted GABA+ and Glx metabolites, which could help with some of the symptoms of ASD. However, the team pointed out that further studies were required.

The possible benefits attributed to both are down to their respective effects on the body’s endocannabinoid system (ECS). The ECS contains endocannabinoids, naturally produced cannabinoids, that bind to receptors located throughout the body. The ECS helps regulate various things such as appetite, pain, and memory.

CBD is one of over 110 cannabinoids produced by cannabis. It is also abundant in the hemp plant. THC is famed for its ability to cause an intoxicating high. In contrast, CBD is non-intoxicating. Nonetheless, there is evidence that both compounds have possible therapeutic effects. This is part of the reason why CBD for sale is now an exciting proposition.

How Do CBD Products Affect the Brain?

CB1 and CB2 are the main cannabinoid receptors, though scientists are confident that there are more. CB1 receptors are mainly found in the central nervous system (CNS). They help regulate mood, pain, coordination, and other crucial functions. CB2 receptors are primarily in the immune system. They have an impact on inflammation and pain.

THC’s effects are akin to those caused by anandamide, nicknamed the ‘bliss’ molecule. It binds to our CB1 receptors, which are responsible for many of the cannabinoid’s intoxicating effects. In fact, THC binds more closely to anandamide’s CB1 receptors than the molecule itself! Anandamide prevents the release of other neurotransmitters, which is part of the reason why we feel a euphoric high after using marijuana.

There is also a possibility that CBD reduces oxidative stress, which occurs at the cellular level. Cells produce free radicals whenever they generate energy. Environmental toxins also produce this waste product. The body utilizes antioxidants to deal with free radical production and ensure the damage they cause is minimized.

Now that you know some basic differences between CBD and THC let’s find out more about CBD and the brain.
