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.
Individuals are continuously suffering varying degrees of anxiety about death. We did a study on “An overview of Death Anxiety”, https://goo.gl/PvKvMJ. Method of concept analyses and an extensive online literature have been used for this study. Overall data provided evidence that anxiety about death is rife within western culture. Its prevalence, particularly with women and significant number of cases elderly people experience less death anxiety than young people.
Cannabidiol has been found to act as an antagonist of GPR55, a G protein-coupled receptor and putative cannabinoid receptor that is expressed in the caudate nucleus and putamen in the brain. It has also been found to act as an inverse agonist of GPR3, GPR6, and GPR12. Although currently classified as orphan receptors, these receptors are most closely related phylogeneticaly to the cannabinoid receptors. In addition to orphan receptors, CBD has been shown to act as a serotonin 5-HT1A receptor partial agonist, and this action may be involved in its antidepressant, anxiolytic, and neuroprotective effects. It is an allosteric modulator of the μ- and δ-opioid receptors as well. The pharmacological effects of CBD have additionally been attributed to PPARγ agonism and intracellular calcium release.
CBD is showing real promise as a compound that can contribute to protecting the brain, thanks to its anti-oxidant and anti-inflammatory abilities. Scientists are investigating its role in neurogenesis and its ability to help the brain heal from injury, and as a treatment for neurodegenerative disease. Research suggests that CBD may help to reduce brain damage from stroke or other neurological injury. And CBD is increasingly looked to as a possible therapy for several neurodegenerative diseases, including Parkinson’s, Alzheimer’s, and multiple sclerosis.
Dan Frey, a physical therapist in Portland, Maine, says that his patients report the most success using CBD to treat long-term trouble spots rather than acute injury sites. Frey, who doesn’t prescribe medication or supplements, says his conversations about CBD are initiated by patients. Many also tell Frey they find it helps with pain management, especially when used in conjunction with other treatments such as massage and a targeted strengthening and mobility program.
About one in ten Americans suffer from restless leg syndrome (RLS). This disorder is characterized by an overwhelming urge to move ones legs while at rest or trying to sleep. These urges are often unpleasant and can cause great discomfort and of course a lack of sleep. The cause of RLS is still unknown, but research suggests that it can be related to abnormalities in the central nervous system.
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).
Early research shows promising signs that a product made from cannabis known as cannabidiol (CBD) oil may help relieve anxiety. CBD is a type of cannabinoid, a chemical found naturally in marijuana and hemp plants. Unlike tetrahydrocannabinol (THC), another type of cannabinoid, CBD doesn’t cause any feelings of intoxication or the “high” you may associate with cannabis. Learn more about the potential benefits of CBD oil for anxiety, and whether it could be a treatment option for you.
There are thousands of unique varieties of hemp. The cultivars used for CBD oil contain significantly higher concentrations of CBD than others. Using these uniquely potent plants, it is possible to extract cannabis oil that contains significant levels of cannabidiol, as well as essential vitamins, minerals, fatty acids, terpenes, flavonoids, and other non-psychoactive cannabinoids.
CBD is shorthand for cannabidiol, one of the more than 100 cannabinoids found in cannabis. CBD products are said to deliver their many claimed benefits by boosting the body’s endocannabinoid system, which is a system that “is a unique signaling pathway that controls the function of a variety of systems throughout the body, including the cardiovascular system,” says Nicholas DiPatrizio, Ph.D., a professor of biomedical sciences at the University of California, Riverside School of Medicine. (More on the endocannabinoid system later.)
Hippocampal neurogenesis: The hippocampus is a major brain area, and plays a critical role in a variety of brain functions. It’s most famous for its role in memory formation and cognition. Brain scans of patients suffering from depression or anxiety often show a smaller hippocampus, and successful treatment of depression is associated with the birth of new neurons (neurogenesis) in the hippocampus.
Various strains of "medical marijuana" are found to have a significant variation in the ratios of CBD-to-THC, and are known to contain other non-psychotropic cannabinoids. Any psychoactive marijuana, regardless of its CBD content, is derived from the flower (or bud) of the genus Cannabis. Non-psychoactive hemp (also commonly-termed industrial hemp), regardless of its CBD content, is any part of the cannabis plant, whether growing or not, containing a ∆-9 tetrahydrocannabinol concentration of no more than three-tenths of one percent (0.3%) on a dry weight basis. Certain standards are required for legal growing, cultivating and producing the hemp plant. The Colorado Industrial Hemp Program registers growers of industrial hemp and samples crops to verify that the THC concentration does not exceed 0.3% on a dry weight basis.
Thirty minutes later, I was surprised by how subtle the effect was. While I expected a hazy nodding-off effect similar to melatonin's, the oil simply relaxed my body ever so slightly—my heart stopped pounding against my chest, my legs stopped kicking beneath my sheets, my mind stopped racing. I wasn't sure if it was the oil or the late hour, but eventually, physical relaxation gave way to mental relaxation, and I drifted off to sleep.
In the United States, approximately 70 million people suffer from insomnia, insufficient sleep or another sleep disorder. CBD has been mistakenly described as sedating. In modest doses, CBD is mildly alerting. Cannabidiol activates the same adenosine receptors as caffeine, a stimulant. But several patients with sleep issues report that ingesting a CBD-rich tincture or extract a few hours before bedtime has a balancing effect that facilitates a good night’s sleep.
Dr. Ethan Russo, medical director at Phytecs, a biotechnology company spearheading research into plant- based medicines and the endocannabinoid system, took issue with Titus’s claim, however. “Bioaccumulators can recruit heavy metals from the soil,” Russo said, “but breaking them down would be alchemy.” Government regulation of the pharmaceutical industry is designed to protect consumers from unfounded scientific claims.
Cannabidiol, or CBD for short, is a natural phyto-cannabinoid (or plant-based chemical compound) found in cannabis plants, including hemp and marijuana. Unlike other cannabinoids — namely tetrahydrocannabinol, or THC — CBD does not produce any psychoactive effects, and will actually counteract these effects to a degree. CBD will induce feelings of sleepiness; for this reason, it can be an effective soporific for people who struggle to fall and/or remain asleep due to insomnia and other sleep disorders.
CBD can fight insomnia without making you get high. On the other hand, certain CBD oil formulations that contain low amounts of THC may also be employed for treatment of this condition. This is why it is very important that your doctor approves of your decision about taking CBD oil or edibles for sleeping disorders. Make sure that you are not self-administering yourself with any online treatment.
Medical reviews published in 2017 and 2018 incorporating numerous clinical trials concluded that cannabidiol is an effective treatment for certain types of childhood epilepsy. An orally administered cannabidiol solution (brand name Epidiolex) was approved by the US Food and Drug Administration in June 2018 as a treatment for two rare forms of childhood epilepsy, Lennox-Gastaut syndrome and Dravet syndrome.
Update 12 October 2018 - Cannabis-based medicinal products will be able to be prescribed by specialist doctors for conditions including epilepsy following a change in the law laid in parliament. From 1 November 2018 specialists, such as neurologists, will be able to prescribe medicinal cannabis on a case-by-case basis where the patient has an unmet special clinical need that will not respond to licensed medications. Anyone who is under a specialist should discuss their treatment plan with them.
Colored impurities from the oil can be removed by adding activated charcoal to about one third to one half the weight or volume of the solvent containing the dissolved oil, mixing well, filtering, and evaporating the solvent. When decolorizing fatty oils, oil retention can be up to 50 wt % on bleaching earths and nearly 100 wt % on activated charcoal.
One of the most experienced practitioners in this field is Los Angeles physician Bonni Goldstein, who has used the compound to treat dozens of children with intractable epilepsy. She says about half of these patients have seen a significant drop in the number of seizures. “Used in the right way, with the right patient, CBD is extremely powerful,” she says.
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.
Why stress happens and how to manage it Stress is essential for survival; the chemicals it triggers help the body prepare to face danger and cope with difficulty. Long-term stress is linked to various health conditions and can cause physical and psychological symptoms. How is it diagnosed, what types of stress are there, and how is it treated or managed?

In recent years, CBD has generated a tremendous amount of interest among consumers, clinicians, and scientists. Why? Not only does evidence suggest CBD counteracts many of THC’s adverse effects, but numerous animal studies and accumulating evidence from human experimental, clinical, and epidemiological studies suggest CBD has powerful anti-anxiety properties. Administered acutely (“as needed”), it appears safe, well-tolerated, and may be beneficial to treat a number of anxiety-related disorders, including:
Here’s my experience: started with insomnia in 2011 that led up to a vicious circle insomnia/anxiety/depression. Took all kinds of sleeping pills/benzodiazepines for around 3-4 years straight until I decided to stop. Yoga, meditation, binaural beats, smoking pot, you name it. I started reading about CBD like 2 months ago and decided to give it a try. I live in Europe so I was able to get my hands in a product that’s a mix of CBD and melatonin. So far it has been working great if I take it after exercising for around 1 hour at the gym. It works well but in moments of high stress it has no effects at all. As soon as I get worried about anything, or if I get sick I’m not able to sleep at all even if I take the whole bottle of CBD oil, I honestly don’t know why, I guess it’s very “mental” but in general I sleep very well after taking CBD oil.
Combining the powerful properties of CBD with a unique mix of herbs and other all-natural ingredients, this Hemp Signature Blend from Bluebird Botanicals offers real and effective relief from the symptoms of inflammation. Designed to support your body and soothe your joints, this is CBD oil redefined. The fascinating inclusion of frankincense carteri, black cumin seed, cold-pressed oil, and rosemary extract marks this out as something special.
Kane fingers one of his innocuous-looking plants, expressing mild bemusement at the U.S. ban on commercial hemp cultivation. “Hemp produces fibers of unparalleled quality,” he notes. “It’s a tremendously high biomass crop that replenishes the soil and doesn’t require much in terms of inputs. We import tons and tons of hemp each year from China and even Canada, yet as a matter of federal policy, we can’t legally grow it. There are places where farmers in the U.S. can literally look across the Canadian border and see fields that are yielding huge profits.”
So Mechoulam called the Israeli national police and scored five kilos of confiscated Lebanese hashish. He and his research group isolated—and in some cases also synthesized—an array of substances, which he injected separately into rhesus monkeys. Only one had any observable effect. “Normally the rhesus monkey is quite an aggressive individual,” he says. But when injected with this compound, the monkeys became emphatically calm. “Sedated, I would say,” he recalls with a chuckle.
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.
It was actually a bad bout of jet lag after a trip to California that inspired me to finally test out the CBD oil (I'll admit that my weed-based reservations kept me from trying it for the first few months). Knowing that the oil had also helped people with sleep issues, I squeezed one full dropper of the Everyday Plus oil onto my tongue, per the instructions, and waited.

Mood enhancement: While CBD isn’t known for provoking a euphoric high, there’s some evidence to suggest that it may enhance mood. Research in animal models notes that CBD yields a combination of anxiolytic and antidepressant effects. That said, this research cannot be generalize to humans. If you’re severely depressed, don’t expect CBD to treat your depression. However, the fact that the drug targets the 5-HT1A receptor and CB1/CB2 receptors suggests that it could improve mood in certain individuals.
CBD also blocked reconsolidation of aversive memories in rat . Briefly, fear memories, when reactivated by re-exposure (retrieval), enter into a labile state in which the memory trace may either be reconsolidated or extinguished , and this process may be pharmacologically modulated to achieve reconsolidation blockade or extinction. When administered immediately following retrieval, CBD prevented freezing to the conditioned context upon further re-exposure, and no reinstatement or spontaneous recovery was observed over 3 weeks, consistent with reconsolidation blockade rather than extinction . This effect depended on CB1R activation but not 5-HT1AR activation .
A study conducted by Martin-Santos et al. (2012) aimed to compare the acute effects of two notable cannabinoids: CBD (cannabidiol) and THC (tetrahydrocannabinol). Researchers recruited 16 healthy males and set up a randomized, placebo-controlled, double-blind, cross-over trial. The 16 participants received three consecutive single-dose agents administered 1-month apart in the following order: 10 mg THC (oral) – first month, 600 mg CBD (oral) – second month, or a placebo – third month.
If he had his way, what Mechoulam regards as the often irresponsible silliness of recreational pot culture would give way to an earnest and enthusiastic embrace of cannabis—but only as a medical substance to be strictly regulated and relentlessly researched. “Right now,” he complains, “people don’t know what they’re getting. For it to work in the medical world, it has to be quantitative. If you can’t count it, it’s not science.”
The interesting thing about CBD and sleep is that in small to medium doses, CBD is mildly alerting – stimulating the same receptors as caffeine. However, several patients with insomnia report that consuming CBD oil (in tincture or extract form) a few hours before bed leads to a great night’s sleep. So why do the anecdotal results contradict the reported medical studies?
A study published in 1993 by Zuardi et al. attempted to elucidate the effects of ipsapirone and cannabidiol among humans exposed to an experimental anxiety task. For the study, researchers recruited 40 healthy volunteers that were assigned to a simulated public speaking (SPS) test – designed to mimic the effects of public speaking. The 40 participants were divided into 4 groups of 10 – each of which was assigned randomly to receive: CBD (300 mg), Valium (10 mg), ipsapirone (5 mg), or a placebo.
An animal study involving male Wistar rats conducted by Resstel et al. (2009) examined the effect of CBD on restraint stress (RS). Previous research had demonstrated that the phytocannabinoid cannabidiol (CBD) yielded anxiolytic and antipsychotic properties in animal models. For this reason, they investigated whether CBD facilitates adaptation to scenarios of inescapable stress and whether this response is mediated by 5-HT1A receptors.
One of the strongest nutraceutical CBD oils is called Charlotte’s Web, with a 50mg dose. Charlotte’s Web is produced in Colorado by the Stanley Brothers, and named after Charlotte Figi, a girl who became famous in the US after her frequent seizures, brought on by the rare Dravet syndrome, were greatly reduced when she started taking CBD oil aged five. The company makes THC products too and is extremely successful, having just offered shares on the Canadian securities exchange, raising about $100m.
