Cannabidiol (CBD), a Cannabis sativa constituent, is a pharmacologically broad-spectrum drug that in recent years has drawn increasing interest as a treatment for a range of neuropsychiatric disorders. The purpose of the current review is to determine CBD’s potential as a treatment for anxiety-related disorders, by assessing evidence from preclinical, human experimental, clinical, and epidemiological studies. We found that existing preclinical evidence strongly supports CBD as a treatment for generalized anxiety disorder, panic disorder, social anxiety disorder, obsessive–compulsive disorder, and post-traumatic stress disorder when administered acutely; however, few studies have investigated chronic CBD dosing. Likewise, evidence from human studies supports an anxiolytic role of CBD, but is currently limited to acute dosing, also with few studies in clinical populations. Overall, current evidence indicates CBD has considerable potential as a treatment for multiple anxiety disorders, with need for further study of chronic and therapeutic effects in relevant clinical populations.
The eCB system regulates diverse physiological functions, including caloric energy balance and immune function . The eCB system is also integral to regulation of emotional behavior, being essential to forms of synaptic plasticity that determine learning and response to emotionally salient, particularly highly aversive events [29, 30]. Activation of CB1Rs produces anxiolytic effects in various models of unconditioned fear, relevant to multiple anxiety disorder symptom domains (reviewed in [30–33]). Regarding conditioned fear, the effect of CB1R activation is complex: CB1R activation may enhance or reduce fear expression, depending on brain locus and the eCB ligand ; however, CB1R activation potently enhances fear extinction , and can prevent fear reconsolidation. Genetic manipulations that impede CB1R activation are anxiogenic , and individuals with eCB system gene polymorphisms that reduce eCB tone—for example, FAAH gene polymorphisms—exhibit physiological, psychological, and neuroimaging features consistent with impaired fear regulation . Reduction of AEA–CB1R signaling in the amygdala mediates the anxiogenic effects of corticotropin-releasing hormone , and CB1R activation is essential to negative feedback of the neuroendocrine stress response, and protects against the adverse effects of chronic stress [38, 39]. Finally, chronic stress impairs eCB signaling in the hippocampus and amygdala, leading to anxiety [40, 41], and people with PTSD show elevated CB1R availability and reduced peripheral AEA, suggestive of reduced eCB tone .
Cannabidiol is currently a class B1 controlled drug in New Zealand under the Misuse of Drugs Act. It is also a prescription medicine under the Medicines Act. In 2017 the rules were changed so that anyone wanting to use it could go to the Health Ministry for approval. Prior to this, the only way to obtain a prescription was to seek the personal approval of the Minister of Health.
Cannabidiol (CBD) is a component of Cannabis sativa that has a broad spectrum of potential therapeutic effects in neuropsychiatric and other disorders. However, few studies have investigated the possible interference of CBD on the sleep-wake cycle. The aim of the present study was to evaluate the effect of a clinically anxiolytic dose of CBD on the sleep-wake cycle of healthy subjects in a crossover, double-blind design. Twenty-seven healthy volunteers that fulfilled the eligibility criteria were selected and allocated to receive either CBD (300 mg) or placebo in the first night in a double-blind randomized design (one volunteer withdrew from the study). In the second night, the same procedure was performed using the substance that had not been administered in the previous occasion. CBD or placebo were administered 30 min before the start of polysomnography recordings that lasted 8 h. Cognitive and subjective measures were performed immediately after polysomnography to assess possible residual effects of CBD. The drug did not induce any significant effect (p > 0.05). Different from anxiolytic and antidepressant drugs such as benzodiazepines and selective serotonin reuptake inhibitors, acute administration of an anxiolytic dose of CBD does not seem to interfere with the sleep cycle of healthy volunteers. The present findings support the proposal that CBD do not alter normal sleep architecture. Future studies should address the effects of CBD on the sleep-wake cycle of patient populations as well as in clinical trials with larger samples and chronic use of different doses of CBD. Such studies are desirable and opportune.
Since then several other so-called endocannabinoids and their receptors have been discovered. Scientists have come to recognize that endocannabinoids interact with a specific neurological network—much the way that endorphins, serotonin, and dopamine do. Exercise, Mechoulam notes, has been shown to elevate endocannabinoid levels in the brain, and “this probably accounts for what jogging enthusiasts call runner’s high.” These compounds, he explains, apparently play an important role in such basic functions as memory, balance, movement, immune health, and neuroprotection.
The good news is that most of the official research done on CBD oil has shown that there are very few negative side effects from using it. However, CBD is not without some side effects. Most notably, in the clinical studies for epilepsy, sedation was one of the more common side effects. Decreased appetite and diarrhea were also seen in some patients. Depending on what other medicines they are taking, certain patients may need to have periodic blood tests to check on liver function.
In his office, however, Hernandez was wary of the CBD boom. He advises well-meaning parents to think twice about voyaging into the world of over-the-counter hemp oil treatments, even if their circumstances are dire. “It’s a huge gimmick that a lot of companies are using,” Hernandez said. “You don’t know what you’re getting. ... There’s a major quality problem.”
Can’t sleep? Cannabis oil also works for people with insomnia. The calming effects of the oil help people to sleep calmly, relieving issues of anxiety and restlessness. A 2015 scientific review published in the American Journal of Health-System Pharmacy found that cannabis treatment is effective for military veterans with post-traumatic stress disorder (PTSD). Research suggests that cannabinoids, the psychoactive components of unrefined cannabis, regulates neurotransmitter release and produces a wide range of central nervous system effects, including increased pleasure and alteration of memory processes.
In terms of cancer, the suggestion is to have three doses of CBD oil each day, and gradually increase the amount to 1 gram per day. The full treatment is believed to take 90 days. Please note that CBD oil is still illegal in many countries, but there is a significant amount of research being done on its medical applications, and a number of reputable sources have put out guides regarding the use of CBD oil for treatment of many diseases.
CBD may help reduces REM behavior disorder in people with Parkinson’s disease. REM behavior disorder is a condition that causes people to act out physically during dreaming and REM sleep. Typically, during REM, the body is largely paralyzed, a state known as REM atonia. This immobilization keeps sleepers from reacting physically to their dreams. In REM behavior disorder, this paralysis doesn’t occur, leaving people free to move—which can lead to disruptive sleep and to injuring themselves or their sleeping partners. Cannabis may also work to reduce pain and improve sleep quality in people with Parkinson’s disease.
In my second experience with CBD, I decided that I needed to double up the dose to determine whether I could enhance the anxiolytic effect. Keep in mind that this was weeks after my first administration with zero CBD usage in between. This time I decided to take 2 capsules of the BioCBD+ in the evening at around 6:00 PM prior to grocery shopping.
No statistically significant differences were found between groups in the VAMS, STAI, Digit Symbol Substitution and Symbol Copying Tests, and PVT. In the analysis of the WAIS, the results in the Symbol Copying Tests showed no effects of drug (F1,24 = 2.46; p > 0.05) or order of administration (F1,24 = 0.44; p > 0.05), but the interaction between drug and order was significant (F1,24 = 4.9, p < 0.05). To check if this interaction could have potentially interfered with the results, we split the subjects, comparing the placebo and CBD groups separately in the two orders (first placebo or CBD). Again, there was no difference between groups in the two situations.
Epidemiological studies of various neuropsychiatric disorders indicate that a higher CBD content in chronically consumed cannabis may protect against adverse effects of THC, including psychotic symptoms, drug cravings, memory loss, and hippocampal gray matter loss [115–118] (reviewed in ). As THC acutely induces anxiety, this pattern may also be evident for chronic anxiety symptoms. Two studies were identified, including an uncontrolled retrospective study in civilian patients with PTSD patients , and a case study in a patient with severe sexual abuse-related PTSD , which showed that chronic cannabis use significantly reduces PTSD symptoms; however, these studies did not include data on the THC:CBD ratio. Thus, overall, no outcome data are currently available regarding the chronic effects of CBD in the treatment of anxiety symptoms, nor do any data exist regarding the potential protective effects of CBD on anxiety potentially induced by chronic THC use.
Very detailed and well researched article, thank you. I would like to highlight the possibility of using CBD suppositories as well, since the bioavailability of rectal administration can reportedly reach up to 70%, compared to 6% via oral ingestion or 30% when vaporized. I have even heard of people who produce their own suppositories or simply inject a mixture of CBD and organic edible oils with a syringe. Might not me the most pleasant option, but obviously very efficient.
Meanwhile, so-called wellness drinks infused with CBD are gaining traction. The UK’s first has been launched by Botanic Lab, promoted as “Dutch courage with a difference”. Drinks giants Coca-Cola, Molson Coors Brewing Company and Diageo are all considering launching their own versions, while UK craft breweries such as Cloud 9 Brewing and Stockton Brewing Company are offering cannabis-oil laced beers, and mixologists are spiking their cocktails with CBD mellowness. The fancy marshmallow maker, The Marshmallowist, has added CBD-oil flavour to its menu, promising that “you feel the effects immediately upon eating”, without specifying what those effects might be.
Again, with all things, each person will react differently so you will have to know yourself well and maybe experiment with a few different concentrations to know what is right for you. My friend used an equal ratio of CBD to THC and after just a week, his blood pressure was down, his bowel movements were much more regular, and it helped with his lactose intolerance.
It is well known that people who consume cannabis in other forms notice increased appetite, famously called “the munchies”. However, cannabis essential oil can help regulate your appetite and induce hunger, while also stimulating your digestive system to operate at a regular level. This can help people who want to gain weight quickly, particularly after an extended illness or injury.
Several studies assessed CBD using contextual fear conditioning. Briefly, this paradigm involves pairing a neutral context, the conditioned stimulus (CS), with an aversive unconditioned stimulus (US), a mild foot shock. After repeated pairings, the subject learns that the CS predicts the US, and subsequent CS presentation elicits freezing and other physiological responses. Systemic administration of CBD prior to CS re-exposure reduced conditioned cardiovascular responses , an effect reproduced by microinjection of CBD into the BNST, and partially mediated by 5-HT1AR activation . Similarly, CBD in the prelimbic cortex reduced conditioned freezing , an effect prevented by 5-HT1AR blockade . By contrast, CBD microinjection in the infralimbic cortex enhanced conditioned freezing . Finally, El Batsh et al.  reported that repeated CBD doses over 21 days, that is chronic as opposed to acute treatment, facilitated conditioned freezing. In this study, CBD was administered prior to conditioning rather than prior to re-exposure as in acute studies, thus further directly comparable studies are required.
In the end, companies like HempMedsPx are asking consumers simply to trust them. CBD oils are never subjected to systematic testing by any U.S. regulatory body. The FDA regulates all pharmaceutical labs in the country. But cannabis labs like the ones that HempMedsPx and others use are not, because cannabis is not federally recognized as a legal drug.
@lalyfa In 2010 I went off a cocktail of psychotropics including antidepressants, antianxiety and antipsychotics cold turkey. The meds were wrong for me and the withdrawal was severe and I rarely slept, had RLS, neuropathy and cranky beyond words. Some of these meds took 9+ months to clear my system. Be sure to follow doctor's advice. I did not have a doctor at the time and would not go to the ER knowing it would have resulted in more abuse. Not an intelligent thing to do and not sorry I made the choice even though the experience was horrific and would not reccomend anyone go this route. As to how long the withdrawal lasts the best thing is to discuss this with a pharmacist as this is where their training is and they understand much better and be of help. Wishing you the best.
As someone dealing with anxiety — hi pals, isn't this pool getting crowded? — all day, every day, taking CBD oil sounded like something that was at least worth a shot. So, I contacted Charlotte's Web by the Stanley Brothers, a CBD hemp oil company based in Colorado. Their hemp oil had positive reviews, which is good for me and my tattered memories of freshman year. They kindly sent me some of their Everyday Advanced Oil, which they recommend taking 0.6 ml of twice a day. I decide to try it for a week.
CBD Living Water is expensive at $5.00 per bottle with 2 servings. It has no flavor (the tincture had a sweet weird flavor I didn't like) and is easy to drink. I only used 4 bottles to help me through my withdrawal. I don't use it now, but I will if I have anxiety in the future. I am impressed with how helpful it was in my withdrawal. I think it would help in withdrawal from cigarettes too. I did that 34 years ago though.
Certain individuals may be more prone to anxiety than others as a result of mu-opioid receptor expression and/or activation. Research indicates that mu-opioid receptors participate in the modulation of anxiety based on the specific region of the brain in which they are stimulated. What’s more, a report published in 2015 indicated that the neural circuitry associated with the DOR (delta opioid receptor) can induce OR inhibit anxiety.
However, CBD oils and the vast majority of other legal CBD-infused products are usually derived from high-CBD industrial hemp. Extracting CBD from cannabis strains is still widely prohibited. In fact, RQS CBD oil is exclusively sourced from organic EU hemp. The most popular CBD products on the market are CBD oils, CBD topicals, and CBD softgel capsules.
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.
People who smoke cannabis often smoke it to get high and for its calming qualities, using cannabis specifically cultivated for very high amounts of THC content. Strains such as skunk are bred to contain as much of the psychoactive compound as possible, with THC levels increasing dramatically over the last few decades due to the popularity of THC’s effects for recreational users.
Devinsky puts more weight behind the scientific advancements: In June, the FDA approved an epilepsy drug called Epidiolex, which contains a purified form of CBD oil. In controlled clinical trials, the drug was proven to reduce seizures in people with Dravet syndrome and Lennox-Gastaut syndrome — and it didn't produce as many of the unpleasant side-effects that come with other epilepsy medications.
I felt like many other users – afraid and nervous to take a dose of something that is supposed to take away my nervousness and anxiety. I use PureKana Vanilla 300mg. I’ve used it off and on for about a month. I started with 3-4 drops to get my body use to it and I noticed that the first night I tried it I ended up sitting on the couch watching t.v. not thinking about whether or not I was feeling ok – I just was. My bf asked how I was feeling and I was just feeling good – normal – calm. The next time, I took 4 – 6 drops but my anxiety overpowered the oil. I was going into a stressful work situation and even though I tried to attack the issue before I thought it would happen I ended up having an anxiety attack until I removed myself from the loud crowd and sat in nature with quietness. It was very discouraging at that point. I decided to give it a break and a week later I felt my stomach butterflies and ‘off’ feeling happening. I took 6 drops and sat outside where I was comfortable with a book and water. I ended up feeling fine and my anxiety just melted away without me realizing it. I think cbd oil is a great natural way to treat anxiety but go into it open-minded. It may work right away but sometimes the situation could outweigh the small dose and you just need more for a more stressful situation. I still believe in the power of the plant. It was put on this earth for a reason – to help!
But Hague has something else he wants to show me. He leads me into a moist propagation room, where a young crop is taking root in near darkness. These babies, tagged with yellow labels, are being grown strictly for medical purposes. They’re all clones, cuttings from a mother plant. Hague is proud of this variety, which contains almost no THC but is rich in CBD and other compounds that have shown at least anecdotal promise in treating such diseases and disorders as multiple sclerosis, psoriasis, post-traumatic stress disorder, dementia, schizophrenia, osteoporosis, and amyotrophic lateral sclerosis (Lou Gehrig’s disease).
Anxiety disorders are far more serious and can prevent you from maintaining a normal life. Some have said that anxiety is not a disease or illness, but rather a physiological, psychological-emotional state that occurs when we behave apprehensively. It turns into a disorder when the worry and the anxiety it creates interfere with your lifestyle. Ongoing anxiety can lead to numerous medical illnesses and even mental issues, if not dealt with.
The DEA isn’t the only government agency scrutinizing CBD vendors. To fend off the FDA, hemp oil companies contend their wares are not drugs but “dietary supplements.” Despite the suggestive “meds” in the company’s name, HempMedsPx is careful to note on its web site, “Although some of our founders are medical professionals, we cannot make medical claims about the benefits of our products.” Others are not quite so nuanced in their marketing. The internet is flooded with CBD products claiming to treat everything from seizures to arthritis to skin conditions and other maladies.
Sample sizes: As was already mentioned, the sample sizes used to test the effects of CBD for anxiety were relatively small-scale. Although the results from these small-scale studies may be accurate, larger-scale trials (with larger sample sizes) are warranted to confirm preliminary outcomes. A therapeutic effect found in just 10-20 patients may not hold up in a group of several hundred.
During my visit, Penny showed me how she administers Harper’s CBD oils. We stood in her kitchen, where a window opened onto a vista of green grass and a wooden swing set out back. After carefully mixing and measuring Harper’s oils, Penny poured the liquid into a jumbo-sized plastic syringe. “We put this all online,” she told me, referring to the several YouTube videos she has made to help other parents administer hemp oil. Penny leaned down over her daughter to fit the tip of the syringe into her gastronomy tube, and I stood by silently. Harper looked at Penny, and Penny smiled back at her, and eased the plunger down.
In general, the preparation methods for unregulated cannabis oil are relatively simple. They do not entail highly specialised equipment, and use easily accessible solvents such as petroleum ether, naphtha, alcohol and olive oil. For this reason, people who have access to cannabis plant material, from either legal or illegal sources, may prepare it at home by themselves.
