McGuire published his own study in August, in which CBD was shown to reduce psychotic episodes in people with schizophrenia. The daily dose was 1,000mg of pure CBD. And a study in which CBD seemed to ease anxiety, published in Nature in 2011, administered a single dose of 600mg, an hour and a half before giving participants a public speaking task. These larger doses contrast with that found in, say, Botanical Labs’ CBD drink. Rebekah Hall, the company’s founder, says her drink is for recreational rather than medicinal purposes and “the amount of CBD per batch is constant and precise, at 2mg per bottle”. A daily dose of two hemp capsules made by Nature’s Plus offers 15mg of mixed “plant cannabinoids” without a specific CBD count.
My trouble falling asleep has never been a major problem. But when I recently learned that nearly 60 percent of people taking cannabidiol—better known as CBD, one of the over 80 compounds found in the marijuana plant—are doing it to help with sleep, I was intrigued. (That stat's according to a survey conducted by Brightfield Group and HelloMD, an online community that brings doctors and cannabis patients together.)
But now, as more and more people are turning to the drug to treat ailments, the science of cannabis is experiencing a rebirth. We’re finding surprises, and possibly miracles, concealed inside this once forbidden plant. Although marijuana is still classified as a Schedule I drug, Vivek Murthy, the U.S. surgeon general, recently expressed interest in what science will learn about marijuana, noting that preliminary data show that “for certain medical conditions and symptoms” it can be “helpful.”
Topical solutions also vary greatly in potency. For example, Prevail Botanical’s salve contains 1,000 milligrams of CBD in 2.2 ounces. Floyd’s of Leadville cream has 700 milligrams in a 30-gram (1.05 ounce) container. These deliver higher amounts of CBD than other topicals I tried, such as PlusCBD’s balm (100 milligrams in 1.3 ounces) and Medterra’s cream (750 milligrams in 3.4 ounces). Remember, more isn’t necessarily better.
There were distinct changes in neural activation associated with the significant anxiolytic effects provided by CBD. When compared to the placebo, administration of CBD significantly: increased ECD tracer uptake in the right posterior cingulate gyrus and decreased ECD tracer uptake in the left parahippocampal gyrus, hippocampus, and inferior temporal gyrus. Researchers concluded that reductions in social anxiety from CBD are related to modulation of neural activity in the limbic and paralimbic regions.
These preliminary findings piqued Blessing's interest. For instance, she points to a 2011 study of a few dozen people, some of whom had social anxiety disorder, who were asked to speak in front of a large audience. Researchers compared anxiety levels in people after they took CBD, compared to those who got the placebo or nothing at all. (The participants didn't know if they'd been given the drug or the placebo.)
Research has shown that administration of cannabidiol actually inhibits agonist effects at the CB1/CB2 receptor sites. Although the effects of CB1 inverse agonism aren’t fully elucidated, many speculate that CB2 inverse agonism may contribute to cannabidiol’s anti-inflammatory effects. Due to the fact that neuroinflammation is associated with anxiety disorders, we could hypothesize that a decrease in inflammation may yield anxiolytic responses in a subset of CBD users.
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.
One thing that I really really liked though, was that the effects seemed to last a long time. I have only taken the oil on four separate occasions now, and each time it’s seemed to last like 6-8 hours (or at least all evening). This makes sense too, because after doing a little reading up I found that the sublingual tinctures are much longer-lasting than CBD vape oils or e-juices.
Glad you're off that stuff and sorry to hear about the hell of cold turkey on that stuff. I've had a taste of that horror missing doses of a benzo, clonazepam, and now tapering slowly over 5 months. The other things – weed psychological addiction, sugar, caffeine, gonna white knuckle the weed as I'm out soon and saving to take the bar exam. I'm going to try using CBD oil as I heard it's effective at reducing anxiety, lifting mood, and so on. Thank you for sharing and wishing you, too, and us all, good health and peace. Will ask my pharmacist about expected withdrawal. Thank you!
Opioid receptor modulator: Another possible mechanism by which CBD may alleviate symptoms of anxiety is through allosteric modulation of mu-opioid receptor (MOR) and delta-opioid receptor (DOR) sites. Though it is known that allosteric modulation of the MOR and DOR is capable of reducing anxiety, it isn’t fully understood how. Some speculate that MOR and DOR sites affect GABAergic and dopaminergic neurotransmission.
Relevant studies are summarized in Table Table3.3. In a SPECT study of resting cerebral blood flow (rCBF) in normal subjects, CBD reduced rCBF in left medial temporal areas, including the amygdala and hippocampus, as well as the hypothalamus and left posterior cingulate gyrus, but increased rCBF in the left parahippocampal gyrus. These rCBF changes were not correlated with anxiolytic effects . In a SPECT study, by the same authors, in patients with SAD, CBD reduced rCBF in overlapping, but distinct, limbic and paralimbic areas; again, with no correlations to anxiolytic effects .
Hey Chris. Thanks for your inquiry. I completely understand why you would like to get off what you’re taking. I’d say a good place to start is with the serving size of the product you buy. A typical range for CBD is 10 – 20 mg of oral doses. CBD products are not very strain focused, so people typically just look at the mg of CBD when making a decision. Any other question, please free to ask away. Here to help 🙂
As noted, CBD has been found to have a bell-shaped response curve, with higher doses being ineffective. This may reflect activation of TRPV1 receptors at higher dose, as blockade of TRPV1 receptors in the DPAG rendered a previously ineffective high dose of CBD as anxiolytic in the EPM . Given TRPV1 receptors have anxiogenic effects, this may indicate that at higher doses, CBD’s interaction with TRPV1 receptors to some extent impedes anxiolytic actions, although was notably not sufficient to produce anxiogenic effects.
CBD is a cannabinoid found in both cannabis and hemp. By using stringently controlled organic hemp – which only contains trace amounts of THC – we ensure that our lab here at Royal Queen Seeds can extract all of the CBD goodness, without any worry of THC contamination. RQS CBD Oil contains less than 0.2% THC, making impossible to get high with it, and legal in most EU countries.
Lidicker noted that one study on humans, published in the journal Neuropsychopharmacology, showed that CBD was able to help with public speaking-induced anxiety. She also pointed to a clinical trial that started in August at a hospital in Massachusetts, in which researchers are administering 10 mg of CBD three times a day for a month to test its effects on patients with anxiety.

A wealth of marketing material, blogs and anecdotes claim that cannabis oils can cure whatever ails you, even cancer. But the limited research doesn't suggest that cannabis oil should take the place of conventional medication, except for in two very rare forms of epilepsy (and even then, it's recommended only as a last-resort treatment). And, experts caution that because cannabis oil and other cannabis-based products are not regulated or tested for safety by the government or any third-party agency, it's difficult for consumers to know exactly what they're getting.
