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.
The CBD utilized in our tinctures is extracted from industrial hemp cultivated in the United States. To further ensure quality and purity, our industrial hemp goes through a supercritical CO2 extraction process to obtain the best possible CBD solution. This solution is then formulated by our board-certified pharmacists into finished products and sent out for third-party testing. Our CBD oil is made with high-quality CBD extracted from organic hemp that is abundant in naturally produced terpenes, oils, vitamins, omega fatty acids, and other components.
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.
For people who suffer from insomnia, constant anxiety during the night or simply struggle to get a sound, restful night of undisturbed sleep, cannabis sativa essential oil may work like a charm. However, according to a research report published by Dr. Ethan Russo, Director of Research for the International Cannabis and Cannabinoids Institute, terpenoids produce an “entourage effect”.
I assume this is also a side effect of the eased anxiety, but I seem to fall asleep within the 20- to 30-minute range rather than my normal 45 minutes to one hour (or longer). Not only do I seem to be skipping (or at least shortening) the whole tossing-and-turning phase of my sleep cycle, but I'm able to snap out of the overthinking mindset that often keeps me up at night. Of course, there's no telling whether a big life event would kindly disrupt this newfound bliss, but I'd like to think it's helped on day-to-day basis.
For the study, researchers recruited 8 volunteers and administered the following: THC (0.5 mg/kg), CBD (1 mg/kg), CBD/THC mix OR Valium (10 mg) or placebo (serving as controls). The volunteers each received the combinations in an order different from the others. Researchers were able to verify that CBD inhibited anxiety as induced by THC, but physiological data revealed it was not a result of direct THC inhibition.
Also mention the specific source from which you attained your CBD (e.g. the company), how you administered it (e.g. orally, sublingually, vaporization, etc.), whether you noticed any unwanted side effects, and whether you use other medications and/or supplements along with it. Understand that CBD appears effective and safe when used for anxiety, but warrants further investigation – especially when used long-term and/or chronically. When used on a situational basis, a single oral dose of 600 mg appears to significantly decrease symptoms of anxiety.
The arrival of Epidiolex is unlikely to erase the unregulated CBD market, however. For one, Epidiolex has been studied only in connection with a small number of epileptic conditions. If and when Epidiolex makes its way to drug stores, it will be approved only for the treatment of Dravet Syndrome and Lennox-Gastaut Syndrome, two rare forms of catastrophic epilepsy. People like me, with comparatively mild Janz Syndrome, and people like Harper, with extremely rare conditions like CDKL5, may still be out of luck.
Cannabis Oil: Cannabis oil is typically made from marijuana with a high THC percentage. Therefore, it must be purchased in an area where marijuana is legal or can be obtained with a prescription. The amounts of compounds, including CBD and THC, will drastically vary from product to product. Commercially produced cannabis oils will have more controlled concentrations of CBD and THC for medical purposes.
Neurologists are skilled at predicting side effects and interactions between well-researched pharmaceuticals. But due to the dearth of reliable research about CBD, doctors like Hernandez and Knupp cannot guide their patients in its use. If there are adverse reactions, Penny will find out because Harper will suffer through them. She has had to figure out through trial and error how best to mix and measure Harper’s oils. The bottom line, Penny said, is simple: “We are the research.”
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.
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.
The equivalency factor is not designed to compare the effects of cannabis oil to dried cannabis, or provide dosage information. For many patients, consuming cannabis orally will produce much stronger effects than inhaling it. For example, when considering a product that has an equivalency factor of 12ml of oil to 1 gram of dried cannabis, and a patient who usually consumes 1 gram of dried product a day, this patient will likely use less than 12 ml of oil per day. Even for patients who have previous experience of using cannabis oil, it is recommend that you start with a low dose and go slow.
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.
All this means that scientists can still only obtain marijuana-derived CBD from farms licensed by the National Institute on Drug Abuse (which until this year meant only one farm owned by the University of Mississippi). As for whether you should have a preference for CBD that comes from hemp, marijuana, or a pure synthetically produced version, there are some theories that THC—and even the smell and taste of cannabis—might make CBD more effective, but Bonn-Miller says these ideas have yet to be proven.
