Although brain fog can be a convenient, shorthand term to describe a general feeling of mental unwellness, different people may experience it in a different way. For example, one person may feel that their brain fog prompts less anxiety, but that their ability to concentrate has reduced over time.
Your body naturally produces its own endocannabinoids to support this system, but just like with any other nutrient, we can have a deficiency and may need extra support. The cannabis plant produces phytocannabinoids that also interact with your endocannabinoid system. There is increasing evidence that CBD may have potential therapeutic benefits, including anticonvulsive, sedative, hypnotic, antipsychotic, and neuroprotective properties.
The scientific understanding, up to this point, is that cannabinoids influence receptors primarily in the endocannabinoid system. The human body also produces cannabinoids on its own and has CB1 and CB2 receptors.
However, other studies concluded that high doses of CBD led to increased tremors and muscle movement in Parkinson’s patients. You have a higher likelihood of finding relief than experiencing discomfort.
CBD’s therapeutic potential with respect to addiction also extends to the serotonin system. Animal studies have demonstrated that CBD directly activates multiple serotonin receptors in the brain. These interactions have been implicated in its ability to reduce drug-seeking behavior. CBD’s influence on the serotonin system may also account in part for its anti-anxiety properties, which have been robustly demonstrated across both human and animal studies.
Thus, CBD can be used to reduce issues with anxiety and even issues with severe anxiety such as panic attacks or the anxiety associated with individuals who are diagnosed with PTSD. This affinity to serotonin accounts for many of its medicinal properties. By modulating serotonin release CBD also affects the release of hormones such as oxytocin (which affects prosocial behaviors) and cortisol (which is released during the perception of stress). This allows CBD to influence issues with mood, sociability, and even thinking. By affecting serotonin perception by neurons in the brain, CBD can be used to treat many issues including pain, depression, nausea from chemotherapy, and severe psychiatric disorders such as schizophrenia2.
However, these products aren't regulated by the FDA and are largely untested. The FDA has warned that CBD products are often mislabeled or overpromise their supposed benefits. In studies, these were more common in the first two weeks on Epidiolex, after which time CBD definition they tended to diminish.
A 2010 study in mice suggests that CBC may affect motor activity, essentially suppressing movement in response to fear in mice. However, a 2005 study of brain activity in 22 people found that CBC did not produce any noticeable changes in the participants' behavior or activity. In medicine, THC is often prescribed in tandem with CBD for a variety of conditions.
