The family of 5-HT receptors or serotonin receptors are a group of G-protein coupled receptors. They play a big role in anxiety. These receptors bind to CBD and when activated by it, and this results in an anti-depressant effect. These receptors also work in processes such as anxiety, addiction, appetite, sleep, pain perception, nausea, vomiting, etc.
Although not as abundant as THC cannabinoid content, cannabidiol accounts for approximately 40% of all cannabinoids within cannabis extract. Unlike THC, cannabidiol is non-psychoactive and isn’t typically ingested with the intent to attain any sort of psychological euphoria. That said, the medicinal properties associated with cannabidiol (often administered in the format of “CBD oil”) are thought to far exceed those of THC.
Formatting: When smoked, the bioavailability of cannabidiol is around 31% – indicating that only about one-third of an actual dose is being absorbed. Researchers should attempt to determine whether alternative CBD formats such as intranasal or transdermal CBD exhibit superior bioavailability to oral preparations. Preliminary evidence suggests that intranasal bioavailability may reach 46%. (Source: http://www.ncbi.nlm.nih.gov/pubmed/20545522).
Overall, existing preclinical evidence strongly supports the potential of CBD as a treatment for anxiety disorders. CBD exhibits a broad range of actions, relevant to multiple symptom domains, including anxiolytic, panicolytic, and anticompulsive actions, as well as a decrease in autonomic arousal, a decrease in conditioned fear expression, enhancement of fear extinction, reconsolidation blockade, and prevention of the long-term anxiogenic effects of stress. Activation of 5-HT1ARs appears to mediate anxiolytic and panicolytic effects, in addition to reducing conditioned fear expression, although CB1R activation may play a limited role. By contrast, CB1R activation appears to mediate CBD’s anticompulsive effects, enhancement of fear extinction, reconsolidation blockade, and capacity to prevent the long-term anxiogenic consequences of stress, with involvement of hippocampal neurogenesis.
Depending on which hormone is stimulated, cannabis can boost or suppress appetite. For this reason, cannabis oil can help patients with eating disorders or be a natural way to treat obesity. This manipulation of the cannabinoid system is becoming popular, and more research is being done to determine its efficacy for patients with weight concerns. (6)
The cannabis plant is filled with hundreds of different compounds, several of which have been studied for decades for their therapeutic benefits. The cannabis compounds that have captured the most scientific interest are known as cannabinoids. Cannabinoids are now used in treatment for a broad—and growing—range of conditions and symptoms, from sleep and pain, to anxiety and inflammation, to Parkinson’s disease and cancer.
In terms of recent scientific investigations on the topic, in 2011 a group of researchers conducted a study that revolutionized the thoughts about CBD and anxiety. They took 10 people with social anxiety who had never had any treatment for this disorder and divided them into two groups. One group was given 400mg of CBD and the other a placebo. The results showed that those who had received the CBD oil had successfully improved their anxiety symptoms compared to the placebo.
Following cloning of the endogenous receptor for THC, namely the CB1R, endogenous CB1R ligands, or “endocannabinoids” (eCBs) were discovered, namely anandamide (AEA) and 2-arachidonoylglycerol (reviewed in ). The CB1R is an inhibitory Gi/o protein-coupled receptor that is mainly localized to nerve terminals, and is expressed on both γ-aminobutryic acid-ergic and glutamatergic neurons. eCBs are fatty acid derivatives that are synthesized on demand in response to neuronal depolarization and Ca2+ influx, via cleavage of membrane phospholipids. The primary mechanism by which eCBs regulate synaptic function is retrograde signaling, wherein eCBs produced by depolarization of the postsynaptic neuron activate presynaptic CB1Rs, leading to inhibition of neurotransmitter release . The “eCB system” includes AEA and 2-arachidonoylglycerol; their respective degradative enzymes fatty acid amide hydroxylase (FAAH) and monoacylglycerol lipase; the CB1R and related CB2 receptor (the latter expressed mainly in the periphery); as well as several other receptors activated by eCBs, including the TRPV1 receptor, peroxisome proliferator-activated receptor-γ, and G protein-coupled 55 receptor, which functionally interact with CB1R signaling (reviewed in [21, 24]). Interactions with the TRPV1 receptor, in particular, appear to be critical in regulating the extent to which eCB release leads to inhibition or facilitation of presynaptic neurotransmitter release . The TRPV1 receptor is a postsynaptic cation channel that underlies sensation of noxious heat in the periphery, with capsacin (hot chili) as an exogenous ligand. TRPV1 receptors are also expressed in the brain, including the amygdala, periaqueductal grey, hippocampus, and other areas [26, 27].

CBD exerts several actions in the brain that explain why it could be effective in treating anxiety. Before we dive in, it’s important to note that most research describing how CBD works is preclinical and based on animal studies. As the saying goes, “mice are not men” — and, results from animal studies don’t always neatly transfer to human therapies. However, preclinical studies provide insights that move us in the right direction:
CBD oil isn’t legal everywhere. In the United States, some states allow it for only specific medical purposes and some don’t. You may need to get a license from your doctor to be able to use CBD. If cannabis is approved for medical use in your state, you may be able to purchase CBD oil online or in special cannabis stores or clinics. As research on CBD continues, more states may consider the legalization of cannabis products.
CBD is available in oils, or it can be added to creams, ointments and beauty products. It can also be used in a vape pen or even consumed through food like CBD gummies. Joel Greengrass, CEO of Theramu, a company that creates non-THC CBD oil, said he has observed a huge increase in interest and popularity of CBD for skin and wellness complaints, as well as for the treatment of a range of anxiety conditions.
The cannabinoids found in both CBD and THC oil mimic the endocannabinoids that our bodies naturally produce. Endocannabinoids are compounds that regulate vital functions such as internal stability, homeostasis, pain regulation, and immune system functioning. Whether they’re produced by the body or obtained from the cannabis plant, cannabinoids facilitate communication on a cellular level between cells to trigger various bodily processes. Therefore, a deficiency of cannabinoids can result in a system thrown out of balance, manifesting in unwanted symptoms and other health complications.
I have lower back pain with some arthritis and arthritis in my hands.ive recently tried CBD Oil. It really does work. I have the drops and ointment. They both work. Because of the back pain I never would have been able to go on a hike with my family. We had a lot of fun. And "No Pain", all day. I'm also Type 2 diabetic. Anxious to see what my A1C is next month. I'm a believer.
Typical treatments for anxiety usually center around either therapy, medication or both. This includes talk therapy or cognitive behavioral therapy, and medications like benzodiazepines, antidepressants, beta blockers and SNRIs (serotonin and norepinephrine reuptake inhibitors). But non-pharmaceutical solutions are also becoming more popular, especially as new research on them emerges. Case in point: CBD products.
The scientific evidence for CBD's ability to quell anxiety, dampen psychosis, and lift the mood is patchy at the moment, although the National Institute on Drug Abuse is optimistic: "CBD has shown therapeutic efficacy in a range of animal models of anxiety and stress, reducing both behavioral and physiological (e.g., heart rate) measures of stress and anxiety."
In an initial experiment, the male Wistar rats received injections of CBD and were exposed to 60 minutes of restraint stress – with cardiovascular responses recorded. In a second experiment designed to determine effects of CBD on the 5-HT1A receptor, researchers administered a 5-HT1A antagonist prior to the CBD. Precisely 24 hours after CBD administration, the Wistar rats were tested in an elevated plus-maze to gauge anxiety.
Human trials are few and far between. The lone 2016 CBD and sleep-related study was restricted to a single adolescent suffering from PTSD and resulting insomnia. Although, the conclusions indicate the poor girl was sleeping better and on the road to recovery with a low sublingual spray dose of CBD. We must disclose that GW Pharmaceuticals founded the Cannabinoid Research Institute that carried out the research.
He emphasises that the company’s products are “whole-plant extracts that include a variety of phytochemicals, not just CBD. These beneficial compounds include a range of phytocannabinoids, terpenes and flavonoids that work together.” This isn’t necessarily seen as a positive by researchers, with McGuire saying: “They muddy the water.” However, Sativex is also a plant extract containing other cannabinoids and substances. David Potter, chief botanist at GW Pharmaceuticals, which makes the drug, says the evidence at the time the drug was developed “suggested there was a synergy between these active ingredients”.
Chronic administration: There’s minor evidence suggesting that chronic administration of CBD may be deleterious to neurophysiological health. This evidence didn’t come from a human study, but discovered that chronic CBD administration (10 mg/kg, intraperitoneal injections) for 14 days reduced BDNF expression in various regions of the brain. It also altered protein expression of TrkB and phospho-ERK1/2 – indicating (potentially) unwanted epigenetic changes.
Animal studies have shown that CBD can be effective in treating anxiety. Research on CBD is still limited, but the early results are promising. Generalized anxiety disorder (GAD) is characterized by excessive worrying and irrational fear. In a 2011 study, researchers found that participants with GAD experienced a significant decrease in anxiety after consuming CBD. Brain scans backed up the findings that were reported by the patients.
Guzmán is a biochemist who’s studied cannabis for about 20 years. I visit him in his office at the Complutense University of Madrid, in a golden, graffiti-splotched building on a tree-lined boulevard. A handsome guy in his early 50s with blue eyes and shaggy brown hair tinged with gray, he speaks rapidly in a soft voice that makes a listener lean forward. “When the headline of a newspaper screams, ‘Brain Cancer Is Beaten With Cannabis!’ it is not true,” he says. “There are many claims on the Internet, but they are very, very weak.”
"Cannabinoids have been found to have antioxidant properties, unrelated to NMDA receptor antagonism. This new found property makes cannabinoids useful in the treatment and prophylaxis of wide variety of oxidation associated diseases, such as ischemic, age-related, inflammatory and autoimmune diseases. The cannabinoids are found to have particular application as neuroprotectants, for example in limiting neurological damage following ischemic insults, such as stroke and trauma, or in the treatment of neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease and HIV dementia.
In addition to that, data from statistics have demonstrated that CBD oil and anxiety are amongst the most explored subjects on the web, that is as far as cannabis-related treatments and restorative medicines are concerned. Particular studies on CBD oil anxiety, have soar exponentially during previous years. This is present-day evidence that traditional cannabis treatments are starting to rise, and in fact, numerous individuals are as of now receiving the rewards of the hemp-based compound.
I had come to meet Dr. Angel Hernandez, the director of the hospital’s pediatric epilepsy program. A trail of wall-mounted signs led me to the pediatric neurology ward, a bright and airy space with flat-screen TVs running cartoons nonstop. Decorative kites were strung up in the corridors, and rainbow curtains lined the windows. Some of the kids in the waiting area that morning were alert and awake, others groggy. Some were strapped into special strollers designed for children with mobility problems, and some had shaven heads and healing scars. Hernandez came out to greet me, and I was surprised he recognized me after what felt like a very long time. He had diagnosed me with epilepsy in 2004 and treated me for several years.
Anti-inflammatory: Many individuals with neuropsychiatric disorders have severe inflammation, particularly neuroinflammation. Neuroinflammation is associated with many causative underpinnings including: air pollution, brain injuries, viruses, and even standard aging. This increase in inflammation can lead to glial cell and cytokine abnormalities, each of which could contribute to anxiety disorders. CBD has been shown to reduce neuroinflammation, which in turn may directly improve anxiety, as well as cognitive function and mood.

Support for legalization has steadily grown over the last several years. Today, medical marijuana is legal in 23 states and the District of Columbia. And even federal officials have begun to soften their stances. Last fall, outgoing Attorney General Eric Holder signaled his support for removing marijuana from the list of Schedule I narcotics. “I think it’s certainly a question we need to ask ourselves, whether or not marijuana is as serious of a drug as heroin,” Holder said. This summer, Chuck Rosenberg, the acting administrator of the U.S. Drug Enforcement Administration, acknowledged that marijuana is not as dangerous as other Schedule I drugs and announced his agents would not be prioritizing marijuana enforcement. Still, as long as marijuana remains illegal under federal law, the haphazard system in which it is studied, produced, and distributed will remain, and Americans will not be able to take full advantage of its medicinal properties.

Both Bonn-Miller and Ward stress that it's up to the consumer to be well-educated about the material they're purchasing and the research that's out there. "The companies that are creating [cannabis oils] are offering lots of claims about its use that are not necessarily substantiated by any research," Bonn-Miller said. So "I think there needs to be, from a consumer standpoint, a lot of vigilance," he added.
