CBD AND YOUR BRAIN While THC interacts directly with the endocannabinoid system in our brains, CBD actually blocks THC from activating the CB1 receptor. This is why cannabis strains with high CBD levels are not as intoxicating as their low-CBD counterparts. CBD has been shown to activate opioid, serotonin, and dopamine receptors in the brain. CBD’s relationship with these receptors could be the reason studies have shown CBD to be useful in treating drug addiction. Opioid receptors are known for their role in pain regulation and are targeted by prescription painkillers such as morphine, heroin, and fentanyl. Dopamine receptors play an important role in regulating behavior and cognition, such as motivation and reward-seeking behavior. CBD’s ability to activate the serotonin 1A receptors can prove to be therapeutic for a wide range of disorders, including anxiety, depression, neuropathic pain, opioid dependence, nausea, vomiting, and schizophrenia. Much of the current CBD research has been tested in animal studies and is prompting scientists to do further research in human trials. The following studies have shown a lot of promise for many debilitating conditions. EPILEPSY Charlotte Figi’s success in using CBD to treat her epilepsy is backed up by science. Studies have repeatedly shown that CBD successfully reduces the frequency of seizures in medicationresistant populations. A 2016 study gave 214 epilepsy patients a 2-5mg dose of CBD in addition to their current medication and monitored them for 12 weeks. The doses were increased over the course of the study until the patients reached their own tolerance level, or a maximum dose of 25mg/day. The results showed patients had 36.5 percent fewer seizures per month. Overall, the study found CBD to be safe and effective for treating epilepsy, even for minors. This study was funded by GW Pharmaceuticals, who developed the drug Epidiolex, a prescription-grade CBD medication that was approved by the FDA in 2018. PAIN Animal studies have provided evidence that CBD is helpful in treating multiple types of chronic pain. A 2018 study gave oral doses of CBD oil to dogs with osteoarthritis and found there was a significant decrease in their pain levels without any noticeable side effects. Another study from the European Journal of Pain showed a substantial benefit to applying CBD topically in animals with arthritis, without any side effects. Sativex, another cannabis-based drug from GW Pharmaceuticals, was approved for use in the United Kingdom in 2010 to treat neuropathic pain, multiple sclerosis, spasticity, and overactive bladder. Sativex is a nasal spray that delivers a dose of 2.7mg THC and 2.5mg CBD in each spray. ANXIETY AND DEPRESSION Some people may be able to manage their anxiety and depression with CBD instead of medication. Low serotonin levels are common in those suffering from anxiety and depression. CBD interacts with serotonin receptors and induces antidepressant effects similar to the drug imipramine, a tricyclic antidepressant. A 2011 study examined the effects of CBD in people who suffer from social anxiety disorder. They gave participants a 400mg oral dose of CBD or a placebo. Researchers found that participants who received the CBD had an overall reduction in anxiety levels. A 2018 study gave 57 male participants a dose of CBD before undergoing a simulated public speaking test. They found that those that received a 300mg dose had significantly reduced anxiety levels. The dose seemed to be important. Participants who received 150mg and 600mg did not see such dramatic results. A 2019 study investigated whether CBD could induce rapid and sustained antidepressant-like effects in rodent populations after just one dose. They found that it did, in fact, have dramatic results, which may be related to rapid changes in synaptic plasticity. Their findings supported using CBD as a fast-acting antidepressant drug. NEURODEGENERATIVE DISEASES In a 2018 review of the neurological benefits of phytocannabinoids, researchers highlighted their therapeutic value in treating malignant brain tumors, Alzheimer’s disease, Parkinson’s disease, multiple sclerosis, and strokes. Research in animal and human models show many therapeutic properties in brain function and protection through its effect on the endocannabinoid system and by influencing endogenous cannabinoids. If you have consulted your doctor and think that CBD would be a good fit for your situation, there are a few different ways to use CBD oil.” 88 Maximum Yield
